4 343 2 2 ΑΊ _____ B7 V. Description of the invention (1) (Technical field to which the invention belongs) The present invention relates to a DL for loading a sintering raw material by magnetic force into a sintering ore used for manufacturing one of the blast furnace charging raw materials. The method of the sintering machine, in more detail, magnetically sinters the rolled sintering raw material layer stacked on the supporting plate of the sintering machine, including rolled iron containing a large amount of metallic iron, and returning iron containing calcium fertilizer grains. Raw materials and fine-grained sintered raw materials are mostly segregated on the upper layer of the sintered raw material layer and loaded onto the pallet. (Knowledge) Printed by the Central Consumers ’Bureau of the Ministry of Economic Affairs and the Consumers’ Cooperative (Please read the precautions on the back first) (Please fill in this page again) When using a DL-type sintering machine to manufacture sintered ore, first add limestone and serpentine as auxiliary materials to iron sources containing metallic iron such as powdered iron ore, sand iron, and rolled iron. Rock, return to the mine, etc., and add sintering raw materials such as coke powder, gas powder, etc. as a fuel source to adjust the granulation to about 7% moisture, as shown in Figure 21, using a drum feeder 3 Sintering The raw material for the sintered ore in the hopper 1, and it will be supplied to the chute 4 is inclined to the flat-panel. By filtration during the sliding down on the inclined chute 4, segregation of the permeation particle size * causes segregation of the fine-grained sintering material in the lower layer portion, and segregation of the coarse-grained sintering material in the middle layer portion. When the lower end of the sintered raw material 2 having a particle size segregation in the vertical direction is loaded on the supporting plate 5 continuously moving in the direction of the arrow, the particle size segregation in the vertical direction is reversed. The relatively fine-grained sintering material is segregated in the upper layer portion, and the coarse-grained sintering material is segregated in the middle and lower layer portions to form a certain thickness of the sintering material layer 7. After that, a large burner (not shown) was used to set the surface layer of the sintered raw material layer 7 on fire. This paper size applies the Chinese National Standard (CNS) A4 specification (210 × 297 mm). System 4 34 3 2 2 A1 _B7_ V. Description of the invention (2) The air above the sintering raw material layer 7 is self-set on the main bar (gratebar) of the pallet 5 by an exhaust fan (not shown)-side The bottom plate 5 is sucked downward, while the pallet 5 is advanced to the end side of the sintering machine, and the sintering operation of the sintering raw material 2 is performed in this process, thereby producing a sintered ore. At this time, the particle size distribution and composition distribution of the raw materials stacked in the height direction of the sintering raw material layer will have an important influence on the sintering result. That is, in the initial stage of ignition by the igniter, the suction air from below the pallet 5 will pass through the interior of the sintered raw material layer 7 whose surface is ignited from the surface downward. In the preheated state, it is supplied to the sintered melting zone formed in the upper layer portion of the sintered raw material layer 7 (for example, a region above 1 200 ° C). In contrast, the air that is drawn downward during the sintering process After being preheated in the sintering completed area formed on the upper layer of the sintering raw material layer, it is supplied to the sintering melting zone formed in the sintering raw material layer and the lower layer. In addition, the inner layer temperature of the upper layer portion of the sintering raw material layer is lower than that of the middle and lower layer portions, and the temperature is kept at a high temperature for a short time. Therefore, the degree of fusion of the sinter ore generated in the upper layer portion is weak, which may cause There is a problem that the strength of the sintered ore becomes weak and the yield of the sintered ore decreases. Here, in recent years, the method of loading sintering raw materials has actively adopted a segregation loading method that consciously changes the particle size distribution of the raw materials and the carbon content in the height direction of the sintering raw material layer deposited on the bracket. It helps to solve the above problems. For example, in Japanese Patent Application Laid-Open No. 61-2231 36, by setting a plurality of strips extending due to the fluid of the sintering raw material loaded on the pallet, the paper size applies the Chinese National Standard (CNS) A4 specification (210 × 297 mm). ) (Please read the notes on the back before filling this page)

The sintered layer formed on the plate has a low density, and the sintering can be improved by improving the air permeability in the upper layer by segregating the fine particles in the upper layer and segregating the coarse particles in the lower layer. Mine yield and productivity. However, this method has a problem that a sintering raw material having a moisture content of about 7% adheres to a plurality of strip-shaped members, and it is difficult to stably maintain the segregation state of the sintering raw material layer originally expected. Furthermore, in Japanese Patent Application Laid-Open No. 63-263386, a plurality of wires are provided in a direction perpendicular to the flow direction of the sintering raw material to be loaded, and the area of the opening between the wires can be adjusted to The sintered raw material layer formed on the pallet after loading has a low density, and the upper layer is fine-grained, and the lower layer is coarse-grained segregation | and by improving the air permeability in the upper layer, the yield of sintered ore can be improved and production can be improved. Sex. This method is printed by the Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs. Although the sintering raw material is removed by winding the wire with a drum to prevent the sintering raw material from adhering to the steel wire, it is necessary to remove the temporary blocking It is very difficult to sinter raw materials between steel cables. Therefore, there is a problem that the segregation state of the sintering raw material layer originally expected cannot be maintained stably. On the other hand, Japanese Patent Application Laid-Open No. 5-3 1 1 2 5 7 discloses that a common sintering raw material is used to mix and blow a combustible gas with a low melting point molten material onto the upper portion of the sintering raw material layer deposited on the pallet. In this method, although the heat of the flammable gas and the low melting point molten material are additionally supplied to the upper part of the sintering raw material layer deposited on the pallet, the sintering reaction here can be enhanced to obtain high strength. Sintering machine, but in order to apply the Chinese National Standard (CNS) A4 specification (210X297 mm) to this paper size 4 34 3 2 2 A7 __C_B7__ V. Description of the invention (4). Supply flammable gas and mix low melting point The raw materials or the conveyed and blown-in materials must be reset, so there are other problems that cause the equipment costs to be greatly enhanced or the equipment needs to be expanded. Furthermore, in Japanese Patent Application Laid-Open No. 58_1 3 3 3 3 3, it is disclosed that an electromagnet is provided at the loading position of the sintering raw material. The electromagnet applies magnetic force to the falling sintering raw material while loading the pallet. Method ◊ Specifically, an electromagnet is installed on a rotor feeder provided below the supply hopper, and the electromagnet causes magnetic force to act on the metallic iron (F e ), And gently lower the dropping speed. At the same time, because the raw material particles with small particles are relatively affected by the magnetic force, they are relatively stronger than the raw material particles with larger particle sizes. Therefore, the smaller the particle size, the slower the falling speed, and the earlier the larger particle size falls, As a result, coarse particles are loaded into the lower layer of the sintering raw material layer deposited on the pallet, and fine particles are loaded into the upper layer, so that a segregated state can be obtained in the sintering raw material layer. Printed by Zhengong Consumer Cooperative, Central Bureau of Standards, Ministry of Economic Affairs (please read the precautions on the back before filling this page). However, the electromagnet is installed in the rotary feeder. When the machine is put into the inclined chute, the segregation situation is reversed up and down, so it is difficult to obtain the opposite effect. In addition, although the electromagnet ION or 0 F F can be repeatedly used to separate the attached iron components, there is a problem that a stable segregation state cannot be obtained due to the magnetic field action and the separation action, and the efficiency is poor.

(Implementation form of the invention) Printed by the Consumer Cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back before filling this page) In the present invention, by filtering the sintering raw material when it slides down on the inclined chute, The particle size segregation produced by infiltration attempts to achieve the conventionally such that coarse sintered raw materials with large particle sizes exist in the upper and middle layer sections, and fine sintered raw materials with small particle sizes exist in the state of particle size segregation in the lower layer sections. In this way, the sintering raw material whose particle size is segregated is promoted by filtration and permeation on the inclined chute. When it is put into the pallet from the front end, a permanent magnet is built in under the inclined chute. Or, a cylindrical magnet drum of an electromagnet causes the magnetic force to act on the fluid of the sintering raw material, so that the rolled iron exhibiting strong magnetism or the returned mill containing calcium fertilizer grain iron is magnetically sintered. The raw materials are magnetized and segregated to the sintered raw materials. The paper size applies the Chinese National Standard (CNS) A4 specification (2 丨 0X297 mm) -12-4 34 3 2? A7 _____ _B7 _ 'V. Description of the invention (1〇) Lower side. Also, the sintering raw material moving on the pallet by the magnet drum, the permanent magnet or the electromagnet hidden in the magnet drum causes the magnetic force to act on the magnetic sintering raw material, thereby reducing its falling speed and being gently loaded. Into the pallet * Φ, that is, the raw material particles with a small particle size are relatively stronger than the raw material particles with a larger particle size. Therefore, the smaller the raw material particles with a smaller particle size, the lower the falling speed and the larger the particle size. The sooner the particles fall, they are charged into the lower layer of the sintering raw material layer. The main thing is that according to the present invention, the magnetic sintering raw material and the falling speed are magnetized by the magnetic force from the magnet drum. The slow-grained fine-grained raw material is segregated on the side close to the outer peripheral surface of the magnet drum (sintering). The lower side of the raw material). Therefore, the coarse-grained and weakly magnetic or non-magnetic sintered material will be segregated on the side far from the outer side of the magnet drum (above the sintering material, the middle layer side). Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page). Then, when the self-magnet drum is loaded on the pallet, the upper and lower layers of the sintering raw material will segregate due to the above. Reversal occurs. Therefore, the sintering raw material layer loaded on the pallet is surely included in the magnetic sintering raw materials, such as rolled iron with a large amount of metallic iron showing strong magnetism or returning iron containing calcium fertilizer grain iron. Among the fine-grained sintering raw materials with a slow falling speed, the coarse-grained raw materials and the magnetically weak or non-magnetic sintered raw materials are mostly contained in the middle and lower layers to obtain a good segregation state. In addition, in the present invention, since the sintered raw material attached to a cylindrical magnet drum having a permanent magnet or an electromagnet embedded therein is cleanly scraped off by a squeegee, it is possible to effectively and efficiently apply magnetic force in addition to In addition to the fluid of the sintering raw material, the sintering raw material can be stably loaded on the pallet from the magnet drum.

Description of the invention (n) More In the present invention, by adjusting the magnitude of the magnetic force of the permanent magnet or the electromagnet embedded in the magnet drum or the permanent magnet or the electric motor built-in; the number of rotations of the magnet drum can be adapted to the sintering raw material. The difference #, that is, the difference in particle size distribution and chemical composition, can be adjusted as desired & the amount of magnetic sintering raw material and fine-grained sintering raw material on the upper part of the sintering raw material layer loaded on the pallet can be adjusted as desired "Improving the sinterability" As a result, even the sintering strength of the upper layer portion of the sintering raw material layer is increased, and as a whole, an operation with a high sintering yield can be achieved. When the permanent magnet is built in the magnet drum, compared with the case of the built-in electromagnet, power is not needed, so the power can be saved, and the above-mentioned effects can be obtained at a low cost. In addition, if the magnitude of the magnetic force of the permanent magnet can be adjusted by adjusting the number of rotations of the magnet drum, the amount of the magnetic sintering raw material in the upper part of the sintering raw material layer can be adjusted efficiently and easily. In addition, when the operating conditions of the sintering machine greatly change, it can be dealt with by replacing the permanent magnet with a different magnetic force or the magnet drum with a permanent magnet having a different magnetic force. In addition, permanent magnets have excellent performance, can be durable for 10 to 20 years, and can be used semi-permanently and stably. When the electromagnet is built in the magnet drum, it is easy to cope with the changes in the operating conditions of the sintering machine as long as the electrical conditions applied to the electromagnet are changed. If necessary, it can also be adjusted by adjusting the position of the magnet drum to deal with the following β. Please refer to the drawings to explain the creative warp and weft of the present invention and the specific implementation mode of the present invention in detail. In order to achieve the above purpose, the present inventors applied the Chinese National Standard (CNS) A4 specification (210X297 mm) to the paper size of the sintering raw material.

'The Fe in the rolled iron will be associated with limestone or iron ore. The original S i 02 reacts to produce a Ca 0 — F e O — S i 02 system with a low melting point (about 1 1 80 ° C) solution. Furthermore, the solution has a low viscosity due to the high content of F e0 And it has the effect of promoting the combination between the ore. Also, the back ore contains a lot of calcium fertilizer grain iron that has reacted with lime (CaO) and iron ore (Fe203). Since it accelerates, the sintering reaction can proceed sufficiently even in the upper layer portion of the sintering raw material layer which is kept at a high temperature for a small amount of time.

At this time, if it is a target amount of magnetic sintering raw material composed of rolled iron in the upper layer portion 7 of the sintering raw material layer 7 stacked on the pallet 5 and being returned to the mine, the built-in magnet drum is adjusted. When the magnetic force of the permanent magnet 1 of 6 is 1, the size of the magnetic sintered paper that is segregated in the upper part 7 A can be applied to the Chinese national standard (CNS) A4 specification (2I0X297 mm) -18-A7 B7 434322 V. Description of the Invention (16) (Please read the precautions on the back before filling out this page) and keep the target value. Here, the adjustment of the magnitude of the magnetic force can be performed by appropriately replacing the intensity of the magnetic field of the permanent magnet 11 and the positional relationship with the magnet drum. * If the number of rotations of the magnet drum 6 is adjusted, the magnetic sintering raw material existing in the upper layer portion 7 A can be adjusted to a target amount on-line. The sintered raw material adhering to the outer ring is scraped off by the main scraper 8 disposed in the non-magnetic field, and as shown by the arrow, it is dropped onto the scraper and recovered. In addition, there is also a sintered raw material layer 7 formed on the pallet 5 by a sintered raw material 2 loaded through a magnet drum 6 and removed by a suitably equipped auxiliary scraper 18. Most of the sintering raw materials that show strong magnetism, such as back ore and iron ore, exist in the upper layer 7A. Therefore, Fe e 0 in the rolled iron will react with Si 02 from limestone or iron ore. The CaO—FeO—S i 02 series has a low melting point (about 1180 °) solution. Furthermore, because the solution has a high content of F e 0 printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs, it is sticky. Low, can promote the bonding between ore. In addition, most of the back ore already contains calcium fertilizer granulated iron produced by the reaction of quick lime (C a ◦) and iron ore (F e 2 03). Once these reactions react, the reaction speed will be faster, so * maintained The time at a high temperature is small, and the sintering reaction can proceed sufficiently even in the upper layer portion 7 A. As a result, the sintering strength of the upper layer portion 7 A of the sintering raw material layer 7 can be increased, and the strength of the entire sintered ore can be improved together with the middle and lower layer portions 7 B. Table 2 shows examples of the blending conditions of the sintering raw materials used. This paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm) -19-4 34 3 2 2 A7 __B7 V.

The sintering material loading device shown in FIG. 10 of the present invention indicates that it is separated directly below the inclined chute 4 and an auxiliary inclined chute is provided in parallel. 14 'while supplying the sintered raw material 2 cut out from the self-supplying hopper 1 through the drum feeder 3, while switching the two inclined chute 4' 1 4 provided in the up-down direction, it is supplied to the built-in permanent magnet 1 1 or the magnet drum 6 of the electromagnet 1 2 »At this time, the commonly used inclined chute 4 on the upper side is set to move freely obliquely upward like an arrow, and is performed between the operating position and the retreat position Move back and forth. Printed by the Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs-Although the inclined chute 4 on the upper side is generally used, in order to remove the sintering raw material attached to the inclined chute 4 on the upper side at a frequency of about 30 minutes, The inclined chute 4 is moved from the operating position to the retracted position, and the sintering raw material adhered to the inclined chute 4 is removed by a separately provided squeegee (not shown). In this removal operation, although the auxiliary inclined chute 14 on the lower side is used, when the sintered raw material 2 cut out from the drum feeder 3 is moved to the magnet drum 6 through the auxiliary chute 14 on the lower side The falling trajectory of the sintered raw material 2 changes at that time. Here, the magnet drum 6 can be set to follow the change of the falling trajectory, and can move freely forward and backward in the horizontal direction shown by the arrow in FIG. 10, while the upper inclined chute 4 moves to the retreat position. , The magnet drum 6 is moved in the left direction. Thereby, the conditions from which the auxiliary inclined chute 14 provided on the lower side is put into the sintering raw material 2 of the magnet drum 6 can be adjusted to the same conditions as when the inclined chute 4 on the upper side is used.

Description of the invention (21). As a result, the magnetization of the magnetic sintering raw material existing in the sintering raw material 2 with respect to the magnet drum 6 can be maintained well, and the sintering raw material 2 can be continuously loaded on the pallet 5 from the magnet drum 6 * If it is When the operation of removing the sintered raw material attached to the upper sloping chute 4 is completed at the retreat position, the magnet drum 6 is moved to the right while returning to the operating position immediately, and returned to the original position by returning The sintered raw material 2 is brought into a state in which the general raw material dropping trajectory passes through the upper inclined chute 4 to the magnet drum 6. The sintering raw material loading device shown in FIG. 11 of the present invention is provided on the lower back surface of the flat-type inclined chute 4 for reducing the speed of the sintering raw material 2 falling on the inclined chute 4 and has a self-propelled 0 0 Gauss to 1 0 0 0 Gauss is a cheap square permanent magnet with weak magnetic force 15.

Description of the invention (22) (Please Read the precautions on the back before filling this page.) The permanent magnet 1 5 installed on the back of the lower part of the inclined chute 4 causes the magnetic force to act on the self-supply hopper 1. It is cut out by the drum feeder 3. The sintering raw material 2 sliding down the chute 4 can reduce the falling speed of the sintering raw material 2 sliding down the inclined chute 4. At this time, the magnetic force can be adjusted by changing the position of the permanent magnets 15 in proportion to the magnitude of the falling speed of the sintering raw material 2. That is, when the dropping speed is large, the magnetic force of the permanent magnet 15 is increased, and when it is small, the magnetic force is reduced, and the sintering raw material 2 is decelerated from the inclined chute 4 by adjusting the magnetic force according to the dropping speed. The front end moves to the magnet drum. The sintered raw material 2 of the drum 6 reduces the falling speed. Therefore, the efficiency of magnetizing the magnetic sintered raw material on the magnet drum 6 becomes higher, and the segregation state of the sintered raw material 2 is strengthened. Furthermore, since the sintering raw material 2 that promotes the segregation state is gently poured into the pallet 5 from the magnet drum 6 at a reduced speed, the sintering raw material layer 7 deposited on the pallet 5 is charged. The density decreases, the air permeability becomes good, and the sinterability can be improved.

The magnetic sintering raw material damaged by the magnet drum 6 is magnetized at 1 degree by the magnetic force in the magnetic field generated by the auxiliary magnet drum 16 to support the segregation of the magnetic sintering raw material. This makes segregation bigger. Therefore, when the self-magnet drum 6 is mounted on the pallet 5, the upper and lower segregation layers are reversed and stacked on the pallet 5. Therefore, the sintering raw material layer 7 can further increase the content.

Therefore, as shown in FIG. 15, among the sintering raw materials 2, the magnetic sintering raw materials pass through the magnet drum. The magnetic force of the permanent magnet 11 of 6 A is magnetized on the outer ring 10, and after promoting its segregation, it moves to the inclined chute 4 B. Secondly, the sintering material sliding down on the inclined chute 4 B similarly filters and permeates the particle size segregation again, and then moves to the second-stage magnet drum 6 B, which promotes the magnetic sintering material. In the segregated state, it is loaded on the pallet 5. According to this structure, since the segregation treatment of the sintered raw material 2 is repeatedly performed at 2 degrees, the segregation is further increased. Therefore, it is possible to cause the magnetic sintering raw material and the fine-grained raw material having a slow falling speed to segregate toward the upper layer portion 7A of the sintering raw material layer 7.

The direction of rotation of the magnet drum 6, as shown by the arrow in the figure, is set to allow the speed of the sintering raw material 2 sliding down on the endless belt 19 to be freely forward and reverse. If the rotation direction of the magnet drum 6 is set to the same direction as the sliding direction of the sintering raw material 2, the falling speed of the sintering raw material 2 can be increased. If it is the opposite direction, the falling speed can be slowed. Adjust the rotation direction and rotation speed to the most appropriate case. At this time, the sintered raw material 21 cut out from the self-supplying hopper 1 is filtered by the filtering and slipping of the endless belt 19 of the belt conveyor-type inclined chute 20, and the particle size segregation caused by the penetration can make the The sintered raw material 2 on the endless belt 19 can move the fine particles to the lower layer portion, while the coarse particles segregate on the upper portion, and move to the position of the magnet drum 6 in the segregated state of the middle layer portion.

The relationship between the magnetic flux density (Gauss) and the falling speed (m / sec) of the sintering raw material printed on the surface of the chute surface by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs is printed. Shown in Figure 25. From Figure 2 5 it can be confirmed that as the magnetic flux density increases from 0 Gauss to 900 Gauss, the falling speed of the sintering raw material will be from 1. 6m / 3 6 (: lowered to 1.2 m / sec.

Description of the invention (31) When the magnetic force of Gauss (Figure 2 6 (A)), it is in contrast to the case where no magnetic force is applied from the permanent magnet 2 2 By comparison, it can be observed that the falling fluid of the sintering raw material expands in the vertical direction. This means that when magnetic force is applied, the falling sintering raw material is gently loaded. Next, in order to investigate the influence of magnetic force on the productivity of the sintered ore, the sintering raw material loading device shown in FIG. 20 is used to make the device move along the inclined chute 4 made of stainless steel (SUS 300).

Description of the invention (32) At this time, when a magnetic force of more than 700 Gauss is applied to the permanent magnet 22 arranged on the end of the inclined chute 4 with a slow falling speed of the sintered 'raw material 2' , The magnetic sintering raw material will stagnate due to magnetic force and become unable to flow, so the magnetic flux density in the upper part of the chute is set to 700 Gauss. In addition, in Experiment No. 2 of Table 2, the magnetic flux density at each position in the height direction of the chute was set to a certain 700 Gauss, and in Experiment N 0.3, the increase in the fall speed was adjusted to The magnetic flux density at the upper part of the chute increases by 900, 1100, and 1300 Gauss.

Furthermore, when comparing Experiment No. 2 and Experiment No. 3, by setting the magnetic flux density higher toward the lower side in the height direction of the inclined chute 4, it can be confirmed that the bulk density can be reduced to 0. 15 t on / m3 , And the productivity is increased to 0.1 lSton / hr-m2 »According to the sintering raw material loading device shown in FIG. 20, not only the magnetic sintering raw material but the fine-grained raw material with a slow falling speed are mostly segregated on the pallet 5. The upper layer portion of the upper sintering raw material layer 7 also has the effect of reducing the bulk density of the sintering raw material layer 7. In addition, even if it is implemented according to the above-mentioned Figure 1 ~ Figure 8 and Figure 9 ~ Figure, the paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) —; ------------ .. —Order— (Please read the notes on the back before filling out this page) Printed by the Central Consumer Bureau of the Ministry of Economic Affairs of the Consumers Cooperatives -35-A7 B7 434322 V. Description of the Invention i 33). The invention shown in 19 In the embodiment, magnetic force is applied to the sintering raw material during the process of loading it into the pallet. Although the effect is different, the effect of reducing the bulk density of the sintering raw material layer can be obtained. (Effects of the Invention) As described above, in the present invention, the sintering raw material cut out by the drum-type feeder in the ore supply hopper provided in the loading device of the DL type sintering machine is loaded on the pallet. At this time, the magnetic force is applied from a magnetic drum or a square permanent magnet with a permanent magnet or an electromagnet built in, in addition to the works of the strong magnetic rolled iron and back to the ore that are present in the sintering raw material. The magnetic sintering raw material is magnetized outside the lower side of the sintering raw material, and the fine-grained raw material with a slow falling speed can be segregated in the lower layer, while the weakly magnetic raw material, non-magnetic raw material and coarse-grained raw material are segregated in the upper layer, and the middle layer portion is segregated. 》 In addition, by reversing the upper and lower layers of the sintering raw material generated when the sintering raw material is loaded on the pallet, magnetic sintering raw materials with good sinterability and good sinterability and fine-grained raw materials with a slow falling speed can be made. Most of them are segregated in the upper part of the sintering raw material layer stacked on the pallet, and the raw materials with relatively low sinterability and weak magnetic properties, non-magnetic raw materials and coarse-grained raw materials are segregated in the middle and lower layers. Moreover, the effect of reducing the bulk density of the sintering raw material layer can also be obtained. Therefore, the sintering strength of the sintered ore sintered on the pallet will be improved, and the strength of the entire sintered ore can be increased together with the middle and lower sintered parts that originally had high sintering strength. As a result, according to the present invention, it is not necessary to perform a major equipment modification on the sintering raw material charging device, and it is not necessary to apply the Chinese National Code of Practice (CNS) Α4 (210X297 mm) IJ.- ---.------- '~ Order (谙 First read and read the notes on the back and then fill out this page) Printed by the Central Laboratories of the Ministry of Economic Affairs and Consumer Cooperatives 36-A7 B7 434322 V.
