Description of the invention (1) [Technical Field] The present invention relates to a method of making continuous entanglement of pin blanks by further improving the surface and internal quality of pin blanks obtained by continuous entanglement. [Background Technology] In the continuous binding of flat copper sheets used in the manufacture of wider dysprosium plates, as a molten copper flow path between the feeding trough for accommodating molten pins and the continuous casting mold, refractory materials are generally used. Made of impregnated nozzle. This impregnated nozzle is easy to adhere aluminum gas (Alumina) to the inner surface of the nozzle especially during the continuous casting of aluminum static copper. Therefore, the molten steel flow path gradually narrows as the time of binding is passed, and there is no way The shortcomings of obtaining the desired flux of molten dysprosium. Therefore, in general, during the supply of the melting pin, an inert gas such as AΓ is supplied into the nozzle to prevent the adhesion of aluminum gas. However, when the discharge rate of molten copper in high-speed high-throughput machining is high, the inert gas will be involved in the flow of the melting pin, and it will not be able to float out of the molten metal surface in the insert and be caught in the solidified shell. The inert gas trapped in the steel will cause defects such as si iyer or expansion in the final product. In addition, in the two-hole nozzle in the form of a two-hole nozzle with a symmetrical discharge port at the lower end of the immersion nozzle, the flow of molten iron in the mold becomes uneven due to the asymmetrical blockage of the left and right sides of the discharge port, resulting in The problem of reducing the quality of manufacturing. At this time, not only is the problem of trapping gas, but also the involvement of the intermediary substance of the bias flow caused by the closure of the discharge port of the injection port and the mold powder. The inventors of this case, mainly used Aj? To deacidify and the sulfonic acid concentration is (please read the precautions on the back before writing this page). Installed.

Description of invention (2) Low master below 500PPm The aluminum is completely sold out and repeatedly checked to find out the clogged nozzle during continuous casting. As a result, a tubular linear sprue with the oxygen concentration in the fuse pin adjusted to 3 ◦ p pm or less, optimally adjusted to 20 p Pm or less, and the front end of the open dip sprue to be the discharge port of the fuse pin was obtained , There will be almost no nozzle clogging. However, in such a linear nozzle, the discharge flow of molten steel is below the mold, and therefore, there is a disadvantage that intervening objects or gas bubbles in the molten pin may penetrate deep inside the molten pin pool. In order to prevent the intrusion of such intermediary objects, there is a technique of applying a static magnetic field generating device that applies a static magnetic field to the casting mold for continuous casting, and applying a brake to the molten dysprosium downward. For example, in Japanese Patent Gazette No. 5-8-5157, it is shown that the level near the meniscus around the mold for continuous casting generates a DC magnetic field, and the molten metal injection is controlled by adjusting its strength and direction The technology of the depth and direction of the intrusion of the flow. In this technique, since the magnetic field is only provided near the crescent, the braking force is insufficient. The inventors of the present invention, by adjusting the gas concentration in the molten steel to a low value, did not blow Ar gas into the nozzle , And the use of linear nozzles, to establish the prevention of occlusion of the nozzle, the other side by the strong molten steel down flow, to create high-quality steel embryo technology. Furthermore, the inventors of the present invention have obtained the braking effect of lowering the flow by molten steel, causing a flow of molten pins in the direction of the crescent portion, and even if the crescent portion due to the flow changes, it is effective to apply a static magnetic field to the meniscus face The effect of braking.

Description of the invention (3) The purpose of the present invention is to provide a tandem setting method that can obtain pin blanks with good surface and internal quality. The other object of the present invention is not to use Ar gas, which can solve the problem that the nozzle will not be clogged during continuous manufacturing. In addition, the object of the present invention is a continuous setting technique of dysprosium embryos that applies an appropriate braking force to the molten dysprosium downflow and also prevents the meniscus from changing as a result. [Summary of the Invention] In order to achieve the above-mentioned objectives, the inventor of the present invention, based on the knowledge obtained above, has technical means as follows. That is, the present invention pseudo-uses molten dysprosium with a gas content of 30 ppm or less in the melting pin, and uses a linear type dipping nozzle, and no inert gas is blown in the nozzle, and the melting pin is supplied from the feeding tank to the tandem As a basic in the casting insert, it also limits the magnetic field conditions attached to the continuous casting insert.

Description of the invention (6) 12, 12 and a pair of long-side walls 14, 14 formed by a continuous casting mold 10, a vertical dipping spout 18 vertical from the feed trough. The straight impregnation 18 is formed in the shape of a tube that opens the discharge port 20 linearly below the nozzle. The static magnetic field generator 22 is arranged on the back of the long side wall 14 of the continuous casting mold 10 and is equipped with Located near the discharge port 20 of the linear dip sprue 18 and at the height of the meniscus 24, and from one long side wall 14 to the other long side wall 14 parallel to the short side wall 12 Static magnetic field. This static magnetic field can slow down the molten dysprosium discharged from the linear dip sprue 18, while suppressing the variation of the meniscus 24, and preventing the mold powder from being caught in the molten iron. Use the mold 10 to change the discharge velocity V of the molten pin from the linear nozzle by changing the throughput of the molten pin, and change the applied magnetic field strength B and the applied magnetic field range (dimension in the height direction) L to observe the cold product Defects in rolled materials. The experimental results of the relationship between the discharge flow velocity V (m / sec) from the nozzle discharge port and the applied magnetic field range L (mm) and the magnetic flux density B (T) are shown in FIG. 2. For the cold-rolled material obtained by changing the magnetic flux density and the applied magnetic field range, the defect occurrence rate obtained by the magnetic flaw detection method is 1 in the non-magnetic field casting method, and less than 0.45 is indicated by a round mark. ◦. 45 ~ ◦. 7 is represented by a triangle symbol, and 0.7 or more is represented by an X symbol. From the results in Figure 2, it can be seen that the defect occurrence rate is compared with the non-magnetic field mounting method, and the coefficient k =. B · L is 25 or more by the magnetic flux density B (X coordinate) and the magnetic field application range L (y coordinate) And the applied distance L is the clothing paper ruler, which is suitable for China In-House Rubbing Standard (CNS) A 4 specifications (210 X 297 public loan)., ^ 装 装 -------- 訂 定 -------- ^ I (please first Read the precautions on the back and fill out this page) Ministry of Economy t Central Standards Bureau®: printed by the Industrial and Consumer Cooperative ** '81.9.25,000 〇l39i * ^ A6 B6 Printed by the Central Bureau of Standardization of the Ministry of Economic Affairs 8 Industrial and Consumer Cooperative. (7) In the area of 80 mm or more and the magnetic flux density of 0.07 T or more, the defect occurrence rate becomes ◦ 4 5 or less. Next, the configuration example of FIG. 9 will be described. In FIG. 9, a linear dipping nozzle 18 is used, and static magnetic field generators 26, 28 are arranged above and below, and between the upper and lower magnetic field generators 26, 28. , A gap portion 30 close to a non-magnetic field that can homogenize the flow of the decelerated solvent is provided. A static magnetic field parallel to the short side wall 12 is applied to the long side wall 14 from one of the long side walls generated by the static magnetic field generator 2 8 below the gap 30, and the static magnetic field generator 2 6 The deceleration of the fuse pin proceeds toward the short side wall 12 and forms a descent on one side. As a result, the downflow of the molten pin which is sufficiently decelerated and uniformized can be obtained. The results of changing the discharge velocity V and changing the magnetic flux density B and the applied magnetic pole range L are shown in FIG. 10, and the defect occurrence rate of the cold-rolled material obtained by the casting method without a magnetic field is compared as 1, and is less than 0. 4 5 is represented by a round symbol, 0.45 to ◦. 7 is represented by a triangular symbol, and 0.7 or more is represented by an X symbol. As can be seen from the first graph, the number of knots obtained by the magnetic flux density B and the applied magnetic field range L = B ♦ L is 16 or more; and the defect occurrence rate becomes less than 4 5. As a result, the applied magnetic field range is also superior to the one-stage magnetic field. As described above, it can be seen that even if the applied magnetic field range and applied magnetic field strength are small, the quality can be further improved. From these results, the following conclusions can be obtained. By using a linear dipping nozzle and a static magnetic field, continuous casting without nozzle clogging can be achieved, thereby improving productivity. In addition, it is important that the flow of molten sales can be inhibited because there is no sprue (please read the precautions on the back before writing this page) 丨 Installation and ordering. .1, Clothing paper ruler applies to China National Standard (CNTS) A 4 Specifications (210 X 297 public loan) 81.9.25,000 A6 B6 2139Γ.1 V. Description of the invention (8) (Please read the precautions on the back before writing this page) Bias, which can be made into clean flat blocks. In particular, due to the prescribed magnetic flux density and the applied magnetic field range, cold-rolled materials with extremely low defect occurrence rates can be obtained. In addition, applying a static magnetic field at the position including the molten gold surface in the continuous casting mold can suppress the fluctuation of the molten metal surface, and applying a static magnetic field near the discharge port of the immersion nozzle, and applying it downward through the gap The static magnetic field can obtain a uniform downward flow of the molten pin. Therefore, a cleaner dysprosium embryo can be produced without the entangled mold powder. In particular, it is extremely important to generate a static magnetic field near the crescent without covering the molten metal surface. For example, when a static magnetic field is not applied to the molten gold surface of dysprosium and a magnetic field is generated only below the molten metal surface, even if the flow under the molten metal surface can be braked, the vibration of the molten metal surface of molten steel cannot be suppressed. Therefore, the mold powder caused by the vibration of the molten metal surface may be caught in the molten metal surface. Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs. Also, in the present invention, the magnetic field has a very important function, but it must be as described below in the field of magnetic fields. First, regarding the static magnetic field, the end before the nozzle is not included, and it can also be applied below the front end. In particular, when the discharge port portion at the tip of the nozzle exists in the magnetic field, the molten americium discharge flow becomes a slow downflow that is sufficiently decelerated by the magnetic field. Secondly, due to the gap and the magnetic field below, the decelerated exhaust flow becomes a more uniform descending flow, and can cast casting pieces with excellent internal and surface quality. In addition, a static magnetic field is generated under the molten steel ejected from the nozzle discharge port to fully cover the continuous mounting mold, and a static magnetic field is partially generated and the mounting is more excellent. ί /?

Description of the invention (9) Secondly, the invention can be borrowed by electricity Additional magnetic field. The second and third images show such an example. In addition to the static magnetic field generating coil 60 that generates a static magnetic field in a direction perpendicular to the long side surface of the binding piece, a straight line perpendicular to the mounting The energizing stick 62 that applies a DC voltage in the direction of the short side of the sheet. The static magnetic field generated by the magnetic field generating coil 60 can be applied only to an appropriate portion below the immersion nozzle discharge port 20, for example, directly below the mold 10, that is, in the central portion of the casting sheet 2 in the direction of the width. In Fig. 23, the direction of the magnetic field B of the molten steel, the direction of the current I, and the direction of the magnetic field strength F are represented by a one-dotted line, a dotted line, and two-pointed dotted lines, respectively. At this time, since the static magnetic field is applied below the immersion nozzle discharge port 20, the downward flow velocity in the insert H can be effectively reduced, and the intrusion of intervening objects or bubbles can be prevented. In the static magnetic field energization and tandem mounting method using the linear dipping nozzle 18, the discharge flow from the nozzle is pseudo-currently flowing in the direction of the uniform downward direction. The position below the outlet 20 is applied to brake the molten copper flow. In the present invention, in order to brake the flow of the fuse from the discharge port of the linear immersion spout, a braking force may be applied to the fuse near the discharge port of the spout by energization. In addition to the static magnetic field generator 8 2 disposed on the back of the long side wall 14 of the continuous casting mold 1◦, there are also energizing terminals 84 for applying a direct current to the direction perpendicular to the short side surface of the chip in the nozzle row Near the exit. In Fig. 28, the direction of the magnetic field B in the fuse, the direction of the current I, and the direction of the magnetic field strength F are represented by a dotted line, a dotted line, and a two-point key line, respectively. Due to the structure of such equipment, in the present invention, the static magnetic field perpendicular to the long side of the insert is generated in the casting pin in the mold-installation ----- tr ------ 1 ( Please read the precautions on the back and then fill out this page) The paper printed by the Ministry of Economic Affairs Central Standards Bureau Jugong Consumer Cooperative is again applicable to the Zhongwei Family Jiazhun (CNS) A 4 specifications (210 X 297 public exchange) _ 81.9 .25,000 A6 B6 39 ^ · i 5.

Description of the invention (14) The result, in the nozzle as 1 〇pi / In the continuous casting of the conventional two-hole type immersion nozzle that uses Ar gas to prevent the nozzle clogging gas from mi η, an aluminum gas deposit layer with a maximum thickness of 10 mm is recognized near the nozzle outlet. In the continuous inlay using the linear dipping nozzle and the I-shaped static magnetic field generator 32, even if Ar gas is not blown into the nozzle, the adhesion layer of aluminum oxide is about 2mm at the maximum, so the nozzle is blocked. Experimental example one 3 The lumps on the molten metal surface of the molten pin in the ladle of the same composition as Experimental Example-2 are added with Αβ powder and Fe is removed from the molten slag on the molten pin surface in the ladle. And concentrate FeO As a ladle refining of 3% or less, the gas concentration in the melting pin is 1 5 ~ 18 p pm. Using this melting pin, under the same casting conditions as Experimental Example-2, three consecutive feeds (280t / Feeding) continuous inlay to investigate the adhesion status of aluminum oxide in the immersion nozzle at this time. Furthermore, in this experimental example, no gas for preventing nozzle occlusion was blown into the two immersion nozzles As a result, according to the conventional method of using a two-hole immersion nozzle, the injection rate that was used to block the nozzle cannot be reached during the third feeding, and the binding speed was reduced from 1. to 1. 2m / min .In continuous casting using linear dipping nozzles, there will be no reduction in casting speed, and after completing the setting, recover the linear dipping nozzles and observe the inner surface, only about 1 ~ 2 mm of aluminum is attached Oxygen.

Invention (15) (Please read the precautions on the back before writing this page) experiment, but under this condition, the high temperature molten pin jet discharged from the front end of the nozzle becomes a strong flow and flows vertically downward. The solidified shell is washed, which prevents the solidification of this part from proceeding. Therefore, it is possible to set the leak and make it impossible to perform the binding. In contrast, in the experimental examples 2 and 3 using the linear dipping nozzle, the static magnetic field is applied , You can get a stable casting as described above. The continuous casting slabs obtained in Experimental Example 1 2 will be hot-rolled and cold-rolled into a cold-rolled material with a thickness of 0.7 mm, and the surface defects of the obtained pin plate (the sum of expansion defects and longitudinal crack defects) will be investigated. ) Incidence. The results are shown in Figure 5. Printed by the Employee Consumer Cooperative of the Central Standards Bureau of the Ministry of Hydrocarbon Economy. In Figure 5, it can be seen that the occurrence rate of surface defects is very small when the tandem setting according to the present invention is carried out. The reason is that the static magnetic field of the casting mold for continuous casting is applied so that the injection flow of dysprosium does not intrude deep inside the depression of the meniscus, and the flow of molten copper in the crescent portion is suppressed without being caught in the mold powder. In addition, the result of the suitable example of Experimental Example 1 is better than that of Experimental Example-2, because the gas concentration of molten steel is low, and Ar gas blowing which is the main cause of expansive defects is not applied. In addition, the comparative example 3 of this experiment also obtained good results, but because the gas for preventing nozzle clogging was not blown into the nozzle, the nozzle clogging occurred, and the desired production speed and production could not be obtained Sex and other shortcomings.

Description of the invention (16) PPm, concentration 450 ~ 55〇ppm, gas A molten pin with a concentration of 25 to 2 8 p pm was continuously subjected to three feed (300t / feed) parts under the following conditions and continuously manufactured to investigate the adhesion of aluminum oxide in the linear dipping nozzle. The T-shaped static magnetic field generator 34 is arranged to have a dimensional relationship as shown in Fig. 7, and uses the strand of the straight-type dipping nozzle 18 and the two strands using the conventional two-hole type dipping nozzle. The binding conditions are as follows: Mold size: short side 2 1 5mm, long side 1 600mm, pound speed: 1. 6m / min superheat of dissolved dysprosium in the feed tank: 20 ~ 25Ό Maximum magnetic flux of static magnetic field generator: 3200 As a result of Gaussian, in the continuous casting of the conventional two-hole type immersion nozzle using the injection of 1 〇Nl / mi η in the nozzle to prevent the nozzle blocking gas, the maximum thickness of 10 mm can be recognized near the nozzle outlet The adhesion layer of aluminum gas, but in the continuous construction of the experimental example using a linear dipping nozzle and a static magnetic field, the Ar gas is not blown into the nozzle, but the adhesion layer of aluminum gas is up to about 2 mm Therefore, it is determined that the nozzle blockage is extremely small.

Description of the invention (17) The FeO in the slag on the surface is refined with a ladle whose FeO concentration is 2% or less, and the gas concentration in the molten steel is 12 ~ 18 P pm. The molten pin was continuously cast three times (300 t / feed) under the same constraints as in Experimental Example 1 to investigate the adhesion of aluminum gas in the immersion nozzle at this time. As a result, in the conventional method using the two-hole dipping nozzle, the injection rate set for the nozzle clogging cannot be achieved at the third feeding, and the casting speed was reduced from 1.6 m / min to 1.1 lm / min. In the continuous setting of the experimental example, without lowering the casting speed, the rectilinear dipping nozzle 18 was recovered after casting to observe the inner surface, and only about 1 to 2 mm of staggered oxygen was attached. In addition, the linear dipping nozzle 18 is used instead of the static magnetic field experiment, but under this condition, the high temperature molten pin flow discharged from the tip of the nozzle becomes a strong flow and flows vertically downward to clean and solidify The shell therefore prevents the solidification of this part from proceeding. Therefore, it is impossible to perform the casting because of the occurrence of the embedding. On the other hand, in the experiment example 1 using static magnetic field 34, 5, due to the application of static magnetic field, stable casting as described above can be obtained. The continuous cast slabs obtained in Experimental Examples-4 and 5 were hot-rolled and cold-rolled to a cold-rolled material with a thickness of 0.8 mm, and the surface defects (expansion defects and stripe-shaped defects) of the obtained pin plates were investigated. Of the total). The results are shown in Figure 8. In Fig. 8, it can be seen that the occurrence rate of surface defects in a suitable example is very small. The reason for this is that the static magnetic field of the casting mold for continuous casting is used so that the injection flow of molten copper will not intrude deep into the molten steel pool and suppress the melting of the meniscus face ----------: --- .----_------ 装 ------ tr ------ f (please read the precautions on the back before filling in this page): The standard is applicable to the Central Wai National Standards (CNS ) A4 specifications (210 X 297 Koji) 81.9.25,000 A6 B6 printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V.

In addition, the results of the suitable examples of Experimental Example 1 and 5 are better than those of Experimental Example 1 because the oxygen concentration of the molten steel is low, and Ar gas blowing, which is the main cause of expansive defects, is not applied. Also in the comparative example of this Experimental Example-5, good results were obtained, but because the gas skull for preventing nozzle clogging was not blown into the nozzle, the nozzle clogging occurred, and the desired casting speed and production could not be obtained Experimental example one 6 of the shortcomings such as sexuality. Secondly, as shown in Figure 9, a linear dipping nozzle 18 is used in one of the strands, and static magnetic field generators 26, 28 are arranged on the upper and lower sides, thereby applying static on the upper and lower sections The magnetic field was used to perform the fabrication experiment, while the other side of the stock was used as a comparative example to perform the fabrication experiment using the conventional two-hole dip nozzle. Both sides of the strand using a static magnetic field and the conventional two-hole impregnated nozzle were blown with 1 ON 1 / m i η to prevent nozzle clogging with gas.

In addition, the result of the defect occurrence rate is shown in FIG. 14. It can be seen from Figure 14 that the incidence of defects is reduced when gas blowing is not performed. In this way, the casting can be performed by blowing the gas without performing it, and a very high-quality plate can be obtained. However, the occurrence of defects during the application of gas blowing also sufficiently reduces the defects. Experimental Example_ 10 Continuous setting was carried out using the continuous setting device shown in Figs. 15 (a) and (b). As shown in Fig. 15 (a) and (b), a linear dipping nozzle 18 having a linear discharge port 20 with a front opening of the nozzle body open is used, and the static magnetic fields 42, 44 are applied up and down. The molten dysprosium supplied in the continuous mold 10 is applied to the magnetic field of the static magnetic field generator 4 2 placed on the continuous casting mold 10 while the brake is applied to the static magnetic field generator 42 to calm the molten metal surface.

In the continuous inlay of the two-hole type dipping nozzle, it was recognized that the largest aluminum gas with a thickness of 12mm was attached near the discharge port of the nozzle. 81.9.25,000 This paper is also a general standard (CNS) A 4 specification (210 X 297 public loan) -Z8 The paper printed by the 8th Industrial Consumer Cooperative of the Central Bureau of Economic Development of the Ministry of Economic Affairs is again applicable to the China Gardener Standard (CNS) A 4 specifications (210 X 297 public loan) _ A6 B6 V. Description of invention ( 27) The target layer, but in the use of linear impregnated nozzles and the use of static magnetic field continuous binding, the thickness of the aluminum gas adhesion layer is an average of 1. Omm at the opening of the discharge port, it can be seen that the nozzle is blocked very little . Example 1 1 1 2 No gas blowing was performed in the two streams, while the other systems were subjected to continuous setting experiments under the same conditions as in Example 1 10. The setting speed at this time was 2.0 m / m i η and experiment example 1 was carried out unchanged. Furthermore, the experiment was conducted after reducing the oxygen concentration in the molten steel to 15 ~ 20PPΠ1 by ladle refining. As a result, it is difficult to control the original flow rate when the two-hole dipping nozzle is opened from the opening of the sliding nozzle at the second feeding, but it is unable to control the end of the pouring of the third feeding because the nozzle is blocked. Achieve the specified injection speed, thus reducing the setting speed. However, in a casting experiment using the linear dip nozzle 18 of the present invention and applying a static magnetic field 42, 44, no nozzle clogging will occur, and the injection speed will not be reduced, so the setting speed will not be reduced either. After the experiment is completed, the two nozzles are recovered, and the blocking conditions are compared. It can be seen that the linear nozzles are only attached to aluminum oxide with an average of 1.0 mm or less. On the other hand, when using the conventional two-hole immersion nozzle, aluminum oxide adheres to the discharge port, and at the same time, the two holes of the immersion nozzle have different blocking methods. As a result, it can be seen that the left and right discharge flows are unbalanced . In addition, the results of Experimental Examples 10 and 11 are collectively shown in Fig. 18. The results in Figure 18 show that the inlaid flat block is hot-rolled and then cold-rolled, and the magnetic flaw detector is used to measure each 81.9.25,000 produced as a cold-rolled plate (please read the precautions on the back first (Fill in this page)-installed · 2139Γ * A6 B6 Printed by the MK Industrial and Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 5. Invention Instructions (28) Defects per unit area and averaged. In addition, after the magnetic flaw detection, it is investigated what causes the defects, and it is found that there are gas causes, intermediary causes, and powder causes. The incidence rate of the surface defects of the cold-rolled sheet at the time of Experimental Example 1 10 is 1 and its comparison shows the incidence rate of other surface defects. The figure 18 shows the conventional mounting method and the mounting method of the present invention. Experimental example of the result of the comparison experiment between 1 0, 1 1. From this result, it can be seen that, in the present invention, the internal defects of the slab are significantly reduced. As shown in the experimental example shown in Figure 18-1 1, especially at the higher purity of the melting pin, not only is there no nozzle clogging, but there is no blow hole defect because no gas is blown in. Excellent effect. Experimental Example 1 12 Using the linear dip sprue of the present invention, a comparative experiment was carried out on a casting method in which a static magnetic field was applied in two stages including a gap portion and a casting method in accordance with a static magnetic field in only one stage. In addition, the injection amount of the gas for preventing nozzle clogging was limited to 15 Nl / m i η from the total of the upper nozzle and the sliding nozzle.

As shown in Figure 15 as the experimental results of the present invention when the two-stage static magnetic field has a nozzle discharge port in the upper magnetic field, and as shown in Figure 16 as a comparative example, the results of the experiment in the one-stage static magnetic field are compared The results are shown in Figure 19.

Taking the conventional defect occurrence rate as 1 indicates the defect occurrence rate of the comparative example. As a result, it can be seen that the defect occurrence rate of the present invention is very low. The comparative example has a higher defect occurrence rate than the present invention, because there is no gap in the applied magnetic field, so the fuse flow is less likely to spread than the present invention (please read the precautions on the back before writing this page) .

Therefore, due to the intermediary substances, air bubbles and other currents in the discharge flow, they are caught in the shell vertically below the nozzle and do not become better. However, these are comparisons in the application of a magnetic field, and it is known that the formation is better than those in the past without applying a magnetic field. This is because the fluctuation of the molten metal surface is suppressed by the applied static magnetic field in both the present invention and the comparative example. In addition, in the present invention, it is known that not only is the exhaust flow decelerated, but also that the discharge flow can be diffused in this portion by providing a gap between the static magnetic fields in the upper and lower stages, and the static magnetic field in the lower stage becomes a more uniform downflow. Experimental Example 1 1 3 A comparison experiment was conducted between the case where the static magnetic field was applied to the entire width area and the case where the static magnetic field was applied to the partial width area. The experiment department uses two strands of continuous casting machine, and uses the low-alloy aluminum with the oxygen concentration of 20 ~ 24ppm to completely sell it. Both sides perform blowing of 1 ONP / m i η to prevent nozzle blocking gas. The casting conditions at this time are as follows. The size of the insert mold: 200mm in the thickness direction, 150mm in the width direction, and 800mm in the height direction. Superheat of molten steel in the feed trough: about 30.

Maximum magnetic flux density. 4T Equipped with the above-mentioned equipment to perform the experiment. In addition, the experiment method of the present invention was used for comparison to perform other stock experiments, and the condition at this time was regarded as the same experiment as Experimental Example 1 1. The results are shown in Figure 20. From the results of Figure 2◦, it can be seen that those applied to a width of 170 mm are superior. However, at this time, even when a static magnetic field is partially applied, it is known that it is superior to the conventional mounting method. Experimental Example_ 1 4 Continuous casting was carried out using the continuous casting device shown in Figure 21 (a) and (b). A linear dipping nozzle 18 having a linear discharge port 20 with an open tip of the nozzle body is used, and the nozzle is supplied to the continuous mold 1 as shown in Figure 21 (a) and (b). The molten steel inside is continuously cast while braking in the magnetic pole area of the static magnetic field generator 58 disposed in the lower part of the continuous casting mold 10. As a result, there will be no nozzle clogging due to the adhesion of aluminum oxide, so (please read the precautions on the back before filling out this page) —install · order_. ^ 'This paper trick & degree applies to Zhongweiyuanjia standard (CNS) A4 specifications (210 X 297 g); 81.9.25,000 A6 B6 printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs V. Description of invention (32) Even when the melting pin is injected into the mold at the desired speed, No intervening objects will penetrate deep inside the molten steel. Also, by this braking effect, even when the flow of molten dysprosium in the direction of the meniscus occurs, the static magnetic field generator 56 provided at the upper part of the continuous casting mold 10, which is equivalent to the position of the meniscus face, The magnetic field brakes the flow of the melting pin, so it can also prevent the mold powder from getting caught on the molten gold surface. Experimental example 1 1 5 Suitable for two-strand continuous inlaying machine, the molten steel refined by the ladle refining C concentration 400 ~ 550ppm, A5 concentration 400 ~ 570ppm, gas concentration 2 3 ~ 2 9 p pm molten steel three times under the following conditions Feed (285t / feed) component and perform continuous casting to investigate the adhesion of aluminum gas in the linear dip nozzle. As shown in FIG. 21, the lower static magnetic field generator 58 is configured such that its upper end is located at a height below 100 mm from the lowermost end of the immersion nozzle, and its lower end is located below 60 mm from the lowermost end of the discharge port position. The upper static magnetic field generator 56 is faked so that its upper end is located above 100 mm of the dysprosium meniscus 24, and its lower end is located below 200 mni from the meniscus 24. Of the two strands, the conventional two-hole dipping nozzle is used in one strand, and the linear dipping nozzle is used in the other strand, and the static magnetic field generator 56 is only applicable to the strand using the linear dipping nozzle 18. 58.

In the continuous inlay of the conventional two-hole type immersion nozzle in which the gas used for preventing the nozzle clogging is blown into the nozzle by blowing 1 〇Nj? / Mi η, it is recognized that aluminum gas with a maximum thickness of 10 mm adheres near the nozzle outlet Physical layer. In continuous casting using a linear dipping sprue and applying a magnetic field, even if Ar gas is not blown into the sprue, it is confirmed that the adhesion layer of aluminum oxide is about 2 mm at the maximum, and the sprue blocking is extremely small. In Experimental Example 14: Ai? Powder was added to the slabs on the molten metal surface in the molten barrel of the same composition, and the Fe in the slabs on the molten metal surface of the molten metal in the ladle was reduced. After the FeO concentration is 2.3% or less, the ladle refining is carried out and the gas concentration in the molten steel is 12 to 16 PPm. Under the same mounting conditions as in Experimental Example 14, the feeding is performed three times (285 t / Feed) Continuously set in succession, and investigate the adhesion of aluminum oxide in the impregnated nozzle at this time.

Description of the invention (34) (Please read the precautions on the back before writing this page) No gas was used to prevent nozzle clogging in the nozzle. As a result, in accordance with the conventional method of using a two-hole immersion nozzle, the injection rate could not be achieved due to the nozzle clogging during the third feeding, and the casting speed was reduced from 1.65m / min to 1. Om / min . In the continuous entanglement of the linear impregnation nozzle and the static magnetic field, and without reducing the casting speed, when the linear impregnation nozzle is recovered after the setting is completed and the inner surface is observed, only about 1 ~ 2mm is attached Of aluminum oxide. In addition, an experiment using a linear immersion nozzle was not applied, and the experiment of static magnetic field was not applied, and the experiment of only the static magnetic field generator at the lower part was applied. It flows vigorously and flows vertically down and cleans the solidified shell, which prevents the solidification of this part from proceeding. Therefore, so-called casting leakage occurs, making the setting impossible. Also, in the latter experiment, stable operations were impossible due to the large fluctuations in the molten metal surface. In addition, under this condition, the flat slabs were rolled by rolling, and when the surface of the cold-rolled pin plate was observed, a large amount of mold powder was present. On the other hand, in Experiment Examples 14, 15, the application of the static magnetic field up and down can be used to perform stable mounting as described above. The Ministry of Economic Affairs, Central Bureau of Standards, Employee and Consumer Cooperatives printed * 'Nong will set up flat slabs obtained in Experimental Example 14,15, and hot-rolled and cold-rolled to form a cold rolled sheet with a thickness of 1.◦ m IT1, and investigate The incidence of surface defects (total expansion defects and streak defects). The results are shown in Figure 22. In Fig. 22, it is found that the incidence rate of surface defects is extremely small when continuous casting using a linear dip sprue and applying a static magnetic field is performed. This reason is because the injection magnetic flux of dysprosium does not use this paper ruler / 5 by applying the Chinese Magnetic Standard (CNS) Grade 4 specification (210 X 297 public exchange rate) 81.9.25.000 due to the application of the magnetic field for continuous mounting molds. Α6 Β6 V. Description of the invention (35) (Please read the precautions on the back before filling in this page) Intruding deep into the molten pool, it can also inhibit the flow of molten salt on the meniscus. In addition, the result of the suitable example of experimental example 15 has a better result than the suitable example of experimental example _14, because the gas concentration of the melted net is low, and the main Ar gas that has become the expansion defect is not applied Formed by the blow-in. In addition, the comparative example 15 of this experimental example can also obtain good results, but because the gas for preventing nozzle clogging is not blown into the nozzle, the nozzle clogging occurs and the desired casting speed cannot be obtained. There are shortcomings in productivity. Experimental Example 1 16 The second and third figures are explanatory diagrams illustrating the configuration of Experimental Example 16. The mold 1 has a static magnetic field generating coil 6 that generates a static magnetic field in a direction perpendicular to the long side of the insert, and a power supply for applying a DC voltage in a direction perpendicular to the short side of the insert. 6 2.

They are represented by a dotted line, a dotted line, and a two-point key line. In the above-mentioned configuration of FIG. 23, the static magnetic field generating coil 60 and the energizing stick 62 provided at the level of the immersion nozzle discharge port 20 in the casting direction are shown separately, but the same structure can also be used The author sets more than two sections in the casting direction.

In the static magnetic field electrified entangled casting method using the linear impregnating nozzle 18, the discharge flow from the nozzle often becomes uniform downward to the molten dysprosium. Therefore, the above-mentioned static magnetic field electrifying artifact is applied only to the impregnating nozzle row The outlet 20 is located further below and is applied near the center of the width direction of the cast H2, and it is only necessary to apply braking to the molten copper flow.

Experimental Example 1 2 0 Figure 29 (a) (b) is a table The structure of the main part of the continuous setting device using Experimental Example 1-20 is shown. On the back of the long side wall 14 of the continuous casting mold 10, a static magnetic field generator 82 is arranged, and in the direction perpendicular to the short side of the casting piece There is a current-carrying terminal 84 for applying a DC voltage.

Inspect the stencil on the inspection production line and compare the occurrence rate of longitudinal cracks and expansion defects caused by copper production. The defect occurrence rate is calculated as defect occurrence rate = defect weight / inspection weight. In the previous example, the longitudinal crack was 0.02% and the expansion was 0.16%. In the present example, the longitudinal crack was 0.03% and the expansion was 0.03%. The mold powder that occurred on the surface of the continuous casting piece, and the longitudinal crack defect caused by the aluminum group casting, there is no big difference between the two. However, for the expansion defects, in the present example, since the conventional method is reduced to 1/5, the present example clearly has the ability to suppress the intrusion of argon gas or intervening substances blown from the nozzle into the The effect inside the film.

Experimental Example 1 2 2 When the same copper type as Experimental Example 2 1 was used to successively set steel with a total oxygen content of 20 ppm or less, it was cast in the same way as Experimental Example 2 1 without blowing argon gas into the immersion nozzle. Mounting under conditions, inspection of cold-rolled steel plates, the occurrence of longitudinal cracking defects of the pinned, rolled, and annealed pin plate according to the present invention is .01%, no expansion defects are found and good results are obtained, However, when the gas is not blown in the general casting method, the injection rate cannot be achieved due to the clogging of the nozzle during the third batch of continuous casting, and the setting speed becomes from 1. 6m / min to 1. . The result of 2m / min. Of course, in the method of the present invention, the casting speed is not reduced, and a slight nozzle clogging of the aluminum oxide adhesion layer of about 1 to 2 nm is confirmed on the inner surface of the linear nozzle after the casting is completed.
