Description of the invention (/) (Please read the notes on the back before filling out this page) The invention is based on continuous casting of metal. In particular, the present invention is directed to the processing of the outer and upper surfaces of spokes or rollers, the latter of which is a mobile villa constituting a mold for continuous casting of flakes made of, for example, gold cymbals. A machine for directly making two-roller continuous ore from liquid gold __making several thick slabs, the mold-laying of which includes a thin gap, the latter of which is defined by two spokes rotating in the opposite direction defined by the sacral axis (which maintains a horizontal state). The lateral side, and the two W hot side plates pressed against the ends of the rollers. These cars can have diameters of up to 1 500 «· and widths of 600 β to 800« in today's S-experience equipment. However, from a long perspective, this S degree will have to be as high as 1 300 to 1 500 · »* K period to meet the production requirements of industrial equipment. These rollers usually include a steel core seat * whose outer periphery is drawn with a sleeve made of arsenic or copper alloy. The sleeve is cooled by circulating K between the core seat and the sleeve or the inside of the sleeve. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs on the surface of the traditional Lian-Mian casting billet, billet or slab. The surface of the sleeve that contacts the liquid metal can be plated with a gold layer. Nickel is usually used and its thickness is typically as high as 1 to 2ra. This nickel layer can adjust the thermal conductivity of the sleeve to the optimal value (this value is lower than if the gold 靥 is in direct contact with 鋦), so that the metal can be solidified under the condition of cutting metallization: too fast solidification will cause Defects on the surface of the product. This adjustment can be performed by changing the thickness K and structure of the nickel layer. On the other hand, it forms a protective layer against copper, preventing it from being subjected to excessive thermal stress and mechanical stress. This nickel layer will wear during the use of the roller, and must be repaired periodically, specifically by removing the remaining thickness locally or completely, and then depositing a new layer. Chinese National Standard (C ^ S) A4 specification (210 × 297 mm) Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention (y) The cost of repairing is lower than the whole replacement due to wear and tear. The precipitation of the high-quality sleeve 0 nickel is preferably performed by the following method K electrolytic method. The new sleeve (a sleeve that has been partially or completely removed) has a hollow shape of a hollow hip, and is made of a rhenium or rhenium alloy such as rhenium (1%) and rhenium (〇 ♦ 1%) rhenium alloy The finished product, which is mounted on a core seat, can be easily transported from one processing station to another station in a mounting / removing factory. After undergoing various preparative surface treatments (calendering, degreasing, pickling) to improve the adhesion to the concrete, the sleeve was sent to a nickel dissolution station. This station pack contains a tank * with plating solution inside, and the core seat above it can be placed in a horizontal position, and the 铙 axis is rotated. In this way, the lower part of the sleeve is immersed in the groove, and κ is rotated at a speed of about 10 rpm, for example. The core seat / sleeve assembly can process the whole sleeve to K. During K-nickel plating, the sheath constitutes the cathode. The emitter can consist of one or more titanium anode baskets immersed in the tank, where the anode blue is enclosed by a thin diaphragm, facing the surface of the sheath. And accommodate nickel balls. If it is also desired that a large portion of the end of the K-nickel-plated sleeve (which rubs against the side plates during casting and is therefore prone to wear) • other pole baskets can be placed facing the ends. Other types of anodes (soluble or insoluble) can also be used. As a variant, measures can be taken to keep the sleeve 茼 still while the electrolyte moves through the sleeve. It is therefore important to create a relative motion between the sleeve and its electrolyte to ensure that the interface between the two is updated. During the casting of the casting, the level of the suspected layer suffered a very high willingness. The machine should comply with the Ten Countries National Standard (CNS) A4 specification (210X297 mm) for this paper size. ---- ^ ------- ^ ------ II I.-ί-(Please read the notes on the back before filling in this page) Printed by A7, Shelley Consumer Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs _____B7_ 5. Description of Invention ($) Both force and thermal stress Have. It is often observed that after only a few foggy castings have melted, cracks appear in the plating layer near the edge of the roller. Some split males spread from the sleeve angle of the sleeve to a few C · wide areas. They may cause defects to form on the surface of the prayer, because it causes the latter to cool unevenly. Gallium * they can form a weakness, and the very rapid deterioration of the nickel plating layer begins. It may even extend the cracks and penetrate the plating layer, which may lead to the destruction of the entire sleeve. Therefore, these cracks will inevitably lead to the immediate and permanent deactivation of the car and the complete re-production of the coating on the sleeve. Because this operation takes a long time (several days), the industrial application of the twin-roll steel casting method requires a large number of backups, and the period K ensures the normal operation of the production. Since the material K used for the sleeve is not easy to process and is a very expensive component, this will cause high costs in using the equipment. The purpose of the present invention is to modify the endurance properties of the metal plating of the sleeve to the thermal mechanical stress. The method is to slow down or even prevent the appearance of cracks in the plaque area as much as possible. Average time between repairs. The object of the present invention is a method of plating a K metal layer on a sickle surface of a double-roller or a spoke of a thin cymbal of a limousine cast iron. In this method, the suspect surface is immersed at least partially. In an electrolytic solution containing gold osmium salt to be deposited, facing the at least one anode, the surface is placed at the cathode, and a relative motion is generated between the casting surface and the dissolution solution, Its special feature is that the insulation cover is inserted between the pole or the anode and the shuttle angle of the surface, and the insulation shield prevents the flow medium from being concentrated on the shuttle angle.

Description of invention (ten) and its vicinity. The object of the present invention is also a device for plating a kappa gold layer on a prayer surface of a roller for continuously forming a thin gold reed roll for a double roll or a military roll. The type thereof includes: a plating tank, It contains an electrolytic tincture containing gold tincture salt to be deposited; a mechanism for immersing the surface at least partially in the plant and for generating a relative movement between the surface and the disintegration substance : At least one stirrup, which is placed in the tank so as to face the casting surface; and a lining for lifting the casting surface to the cathode potential; characterized in that the device includes a shield made of an insulating material, which The shields interposed between the Burmese surface and the anode or the anodes * The shields can prevent the flow media from concentrating on the shuttle angles. Preferably, the shields have the general shape of a round shape, the center of curvature is the same as the corners of the mineral surface facing them *, and they have two parallel sides, each side being placed at the extension of the shuttle angle , The same distance from the latter 〃d " * and the two sides are connected by a corner cut, the sides of the cut are perpendicular to each other. It will be understood that the present invention includes electrode deposition of a gold layer by placing an insulating shield near the jacket. These garrisons (with a good example described) are designed to achieve a uniform streamline distribution in the edge area of the nest. This will give the 锼 layers M uniform thicknesses in these areas * to the desired nominal thickness. The inventors have discovered that the rapidity of cracks in the plating layer in the edge area of Tall and the uniformity of the thickness of the coating in these areas are maintained in accordance with the Chinese National Standard (CNS) A4 specification ( 210 × 297 mm) /. ----; -------- Yishui ----- 1T.-Guang i · (Please read the precautions on the back before filling this page) A7 _B7_ V. Description of the Invention (f) (Please read the precautions on the back before filling out this page) There is similarity, especially at the corner of the shuttle. In the absence of any special device design to prevent this phenomenon, the phenomenon of excessive thickness of the plating layer was found to occur near the middle of the shuttle corners of the sleeves, and to hold these shuttle corners themselves. For example, if the nominal thickness of the box layer is 2m over a large part of the sleeve surface, it may sometimes be found that the thickness is greater than 7η · at the shuttle angle. Some of these over-thickness phenomena can be attributed to the concentration of current media near the middle of these shuttle angles. Even though these concentration phenomena exist only in very limited parts of the sleeve *, it seems that the above-mentioned cracks occur rapidly enough. This is because it has been confirmed that they have generated hydrogen from K, which may cause gas-containing phenomena in the forming sedimentary area. And • these concentration phenomena make the lattice structure of the nickel plating layer, and hence its hardness and its group, suspect that the edges and corners are non-uniform with the rest of the suitor. One way to reduce this phenomenon of through-thickness of the plating layer is to give the shuttle angle a radius of curvature of several meters instead of making it a sharp edge. However, in practice, this radius must not exceed 1 to 2 m, otherwise the possibility of liquid gold splashing between the end of the roller and the firing side plate will increase. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Another conventional method involves skewing the streamline by means of a device called " data collector β. These devices are metal-guided, and are arranged parallel to the shuttle angle and its vicinity through which the flow medium passes. They skewed some of the current medium towards them, and without these devices, these current lines would have concentrated on the shuttle angle of the sleeve and its surroundings. However, this solution is not satisfactory when used alone. Moreover, the positioning and operating parameters of these current collectors must be carefully measured, because otherwise, in addition to the phenomenon of through-thickness, the edge will still exist, sometimes it will be found that the opposite, the thickness of the plating layer in a certain place will be less than the nominal thickness -8- This paper size applies to Chinese National Standard (CpS) A4 specification (210 × 297 mm) A7 B7 V. Description of invention (") (Please read the" I "on the back of t» before filling out this page), table These current media are excessively deviated from the corresponding areas. Furthermore, when electroplating is performed, nickel is deposited on the current collectors in a non-negligible amount. Therefore, it is necessary to recover this chain, and it is for the sake of sedimentation. The current consumed is a pure loss. But the most important thing is that this disastrous change changes the size of the data collector, and then it can work in a very standardized way. Therefore, when the work is in progress, the data collector The effect varies greatly, which makes it difficult to manage. In fact, for the required coating thickness of 2 ··, the coating has a thickness of 2 · 5 on the edges and corners has been considered the best, but this value is still too high to make it Satisfactory resolution Therefore, for this application, the streamer cannot reliably achieve satisfactory nickel deposition uniformity, especially for the tinplate of lotus reading casting rolls. The inventors have discovered that the A very uniform nickel deposit was obtained in the middle and near the middle. The most reliable way is to place an insulation shield, preferably the specified structure shape, a short distance from the shuttle angle * and found that under these conditions, it is located in the edge area of the sleeve The phenomenon of premature cracks in the coating can be eliminated by K.

Description of the invention (β) 2 1〃 Vertical anode The first circle K section view shows a device according to the present invention. * The cross-section plane is located within the perimeter of 霣 plating 1 which contains the electrolyte (the main component of which is H), but it is placed as The copper sleeves 3, K of the cathode are placed before the two anodes 4, 4 'at the bottom of the plating tank 1. The sleeve 3, which has a cylindrical outer shape and an outer diameter of 1,500 m, is mounted on a core seat 5, and the sleeve 6 of the latter is rotated by a mechanism not shown in the figure during K plating operation. At least the lower part of the holster 3 is immersed in a holm plating right. In the example shown, the anodes 4, 4 'are soluble anodes and consist of an arc-shaped titanium anode basket filled with particles. However, rhenium is only one embodiment, and different numbers of rhenium plates and other structural forms (for example, an insoluble anode) can also be provided. The anodes 4, 4 'extend beyond this cross-section. After the plane, their width is larger than the sleeve 3. Those treated as straight edges of the holster 3 are shields 7, 7 'made of insulating material (only 7 is visible in the first holster), and its function is to prevent the current lines from the anodes 4, 4' from reaching the holster. Edge area and edges, K to avoid the nickel plating on it is too thick. The positions of these shrouds 7, 7 'relative to the silk cover 3 can be adjusted by the positioning structure in which the moving rod 8 is shown in FIG. The exact form of these shields 7, 7 'is shown in the second figure. In the example shown, they present an elongated shape of approximately a square or rectangular cross section * and an overall shape with a curved shape, the center of curvature of which is the same as the shuttle angle of the copper sleeve 3 facing. Their upper edges are closest to the edge of the sleeve and exert an effect on them. These upper edges have a corner cutout 9, 9 ', the latter of which is -11-.

(Please read the ji · Issue on the back of ## before filling this page) Order the wisdom of the Ministry of Economy A7 B7 printed by the Consumer Cooperative of the Property Bureau V. Description of the invention (1) Both sides are vertical and approximately the same length, for example, about 5m. The shields 7, 7 'are arranged by the rod 8 plus K so that the outer edges 1 1, 1 1' of the cutouts 9, 9 'are each placed at about the same shuttle angle 1 2 from the facing net cover 3 The distance 〃 d 〃. When it is desired to deposit nickel to a thickness of 2 to 3 m, this distance 〃 d " is initially about 5ra. On the other hand, the sides 1 3, 1 3 'of each shield 7, 7' must have a minimum length of 50 «in this embodiment of the present invention. It is precisely that under these conditions, the protection of Qin 7, 7 'can fully polarize the Xiaoliu media, making it the best distribution uniformity in the plaque field on the edge of the sack. As an option, the shields 7 and 7 'can be arranged such that K gradually moves away from the jacket 3 as the thickness of the plating layer increases. This movement can be performed in a step-by-step manner or by continuous reading. This ensures that there is sufficient clearance to remain between the shield and the coating at all times, and the K phase allows the rhenium nickel calendar to grow. It is suspected that the precise shapes of the anodes 4, 4 'and the shields 7, 7' are different. The plating on the ends of the silk cover 3 will be performed uniformly on the larger or smaller surface portions. In order to increase this part, the vertical anodes 21, 21 ', 21 ... are like the anode house filled with training particles *, which can be similar to the end of the anode basket 4, 4' and facing the sleeve 3, as It has been mentioned in the prior art that it is generally placed in the slot 1. Obviously, these shields may differ in their structure from those given as an example, as long as they can achieve the desired uniformity of the thickness of the coating to be achieved. In particular, they may not be composed of square, rectangular or other sections of elongated bodies, but may be composed of a plate or a plate assembly. * The surface of the plate or plate assembly facing the feeding jacket preferably has the same as that in the example. -12- This paper size applies to the Chinese National Standard (CNS) A4 specification (210X297 mm) ----------- clothing-• · * (please read ^ & on the back first) Please fill in this page for the matters needing attention) Print the A7 B7 399106 printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs V. Description of the invention (/ to) Structure. In other words * this surface should preferably include two parallel sides, which should be at the extension of the shuttle sleeve angle, the same distance from the latter " d " and connected by a corner cut, Its sides are perpendicular to each other. The present invention does not exclude this feasibility. The K-phase supplements and further refines the effect of the shroud. * It is also possible to use the data flow device permanently or indirectly, that is, these flow devices are added to the cover or are independent of the latter. Of course, the present invention can be used to deposit non-nickel gold rhenium onto a holster. In the same way, the shovel formed in this way can be used not only in the double-roller continuous pin gold slabs (made from period or other materials), but also in the slabs for continuous casting and one of the rotating cars gently licks the metal. In the eaves on the surface of the liquid pool (army casting). Moreover, it can also be used in the case described below, that is, the cast surface of a solid shaft is plated * in which the sleeve and the core seat are formed into a single body and the same workpiece. It can also be easily transformed into a situation where a suitable sleeve or solid roller is completely immersed in the electrolytic cell. Finally, as above, the relative movement between the nesting and the decomposing mass can be produced by keeping the sleeve stationary and the electrolyte moving around its periphery. This can be achieved by K, especially when the sleeve is completely immersed in the hydrolysis solution, and the movement of the hydrolysis solution is generated by the nozzles in a certain interval to circulate the electrolyte between the anodes and the anodes around. -13- This paper size is applicable to China National Standard (CNS) Α4 size (210X297mm)
