The present invention relates to a continuous casting mold panel suitable for casting molten steel while applying electromagnetic stirring. In continuous steel casting, a technology has been developed in which molten steel in a mold is stirred by electromagnetic force in order to improve the quality of slabs. This technology uses electromagnetic force to stir molten steel that is in the process of solidifying, thereby increasing the equiaxed crystal region in the cross section of the slab, reducing segregation in the steel ingot and improving hot workability of the slab. It is also an excellent technology that can reduce blowholes and nonmetallic inclusions in the slab surface area and improve the yield of steel ingots, and the higher the magnetic flux density in the mold, the better the effect. . By the way, the conventional mold panel for continuous casting of large slabs has a plate thickness of 40 mm, as shown in Fig. 1 as an example in perspective view and as shown in Fig. 2 in partially enlarged horizontal sectional view. A copper alloy inner plate 1 with a thickness of ~70 mm and a non-magnetic stainless steel back plate 2 with a plate thickness of 40 to 50 mm.
Both plates have a layered structure, and both plates have headless non-magnetic stainless steel bolts 4 screwed into screw holes 3 provided at a plurality of predetermined locations on the inner plate 1, and bolt through holes 5 provided on the back plate 2. The bolts 4 are inserted into the back plate 2 and nuts 6 are screwed onto the bolts 4 on the outside of the back plate 2, thereby integrally connecting them. Further, a groove 7 which becomes the cooling water channel A was formed on the back side of the inner plate 1, and the groove 7 was formed into the cooling water channel A by combining the inner plate 1 and the back plate 2 together. . That is, since the bolts 4 for connection cannot be welded to the inner plate 1, they must be screwed, which increases the thickness of the plate, and the stirring effect cannot be achieved even if a large-capacity electromagnetic coil is used. Therefore, if you try to obtain a higher electromagnetic stirring effect using a conventional mold panel, you will have to use an electromagnetic coil with a much larger capacity, which will increase the cost of continuous casting. This was unavoidable, and although it was possible to improve the quality of the product, it had the disadvantage of increasing costs. Therefore, the present inventors conducted research based on the viewpoint that the reason why it was not possible to reduce the thickness of the inner plate was due to the screwing of the coupling bolts to the copper alloy inner plate. , in weight%, contains Cr: 0.4~1.5%, Zr: 0.01~0.3%, Al: 0.05~0.8%, Ti: 0.01~0.6%, and further contains Fe, Ni, and Co as necessary. When composed of a precipitation-hardening copper alloy containing one or more of these: 0.05 to 1%, and the remainder consisting of Cu and unavoidable impurities, this copper alloy has an electrical conductivity of 30 to 70%. (IACS%), it is possible to vertically weld non-magnetic stainless steel bolts to this copper alloy inner plate using the arc stud welding method, and as a result, the thickness of the inner plate can be reduced to 5. They found that it would be possible to make the film thinner to ~25mm. Therefore, this invention was made based on the above knowledge, and consists of a two-layer structure of an inner plate made of copper alloy and a back plate made of non-magnetic stainless steel, both plates being made of non-magnetic stainless steel. In a mold panel for continuous casting that is integrated with bolts, the above inner plate has the following weight percentages: Cr: 0.4 to 1.5%, Zr: 0.01 to 0.3%, Al: 0.05 to 0.8%, Ti: 0.01 to 0.6%. and, if necessary, one or more of Fe, Ni, and Co: 0.05 to 1%, with the remainder being Cu and unavoidable impurities, and IACS% of 30 to 1%. Constructed of copper alloy with 70% electrical conductivity, and its thickness is 5 to 25%.
mm, and is further characterized by a bolt mounting structure welded upright on the back of the inner plate by arc stud welding, and grooves that serve as cooling channels are provided on the back plate. It is something. Next, in the continuous casting mold panel of the present invention, the reason why the composition range, electrical conductivity, and plate thickness of the inner plate are limited as described above will be explained. A Component composition (a) Cr The Cr component has the effect of improving the strength at room temperature and high temperature, but if the content is less than 0.4%, the desired high strength cannot be secured; on the other hand, if the content is less than 1.5% Since toughness decreases when the content exceeds 0.4% to 1.5%. (b) Zr The Zr component has the potential to further improve high-temperature strength,
It has the effect of improving heat fatigue cracking resistance by improving high-temperature ductility, but if its content is less than 0.01%, the desired effect will not be obtained.
On the other hand, if the content exceeds 0.3%, a tendency towards embrittlement appears, so the content was set at 0.01 to 0.3%. (c) Al The Al component has the effect of improving sulfur attack resistance and preventing corrosion fatigue cracking in the mold, as well as improving oxidation resistance, and allows for wide-ranging adjustment of electrical conductivity. The content is 0.05%.
If it is less than 70%, the desired effect will not be obtained, and the electrical conductivity will be particularly high, exceeding 70%, and when welding the bolt to the inner plate,
A weld heat-affected zone begins to form on the inner surface of the inner plate, and on the other hand, when its content exceeds 0.8%,
The electrical conductivity of the inner plate may be less than 30%, making it difficult to secure the desired heat removal effect, so the content was determined to be 0.05 to 0.8%. (d) Iron group metals These components have the effect of further improving strength at room temperature and high temperature, so they are included as necessary when particularly high strength is required, but their content is less than 0.05%. However, if the content exceeds 1%, the toughness decreases, so the content was set at 0.05 to 1%. (e) Ti The Ti component has the effect of improving heat resistance and oxidation resistance, but its content is 0.01%.
If it is less than the desired effect, the desired effect cannot be obtained.
On the other hand, if the content exceeds 0.6%, the toughness will decrease, so the content should be
It was set at 0.01% to 0.6%. B Plate Thickness If the plate thickness is less than 5 mm, the strength will be insufficient and it will be impossible to avoid the formation of a weld heat affected zone on the inner surface of the inner plate during arc stud welding of non-magnetic stainless steel bolts to the inner plate. ,on the other hand,
If the plate thickness exceeds 25 mm, the electromagnetic stirring effect will be reduced, so the plate thickness was set at 5 to 25 mm. C Electrical conductivity If the electrical conductivity is less than 30%, the inner plate thickness should be reduced by 5%.
Even if the thickness is reduced to 25 mm, the heat removal effect becomes insufficient, and on the other hand, when the electrical conductivity exceeds 70%, even if the inner plate is 25 mm thick, when arc stud welding is applied to the inner plate of a stainless steel bolt, Since a weld heat affected zone will be formed on the inner surface of the inner plate, the electrical conductivity was set at 30 to 70%. Further, the diameter of the stainless steel bolt in the mold panel of the present invention is preferably 5 to 20 mm from the viewpoint of welding problems, the strength of the bolt itself, and the welding strength. Next, the mold panel of the present invention will be explained by way of example with reference to the drawings. Embodiment FIG. 3 shows a perspective view of an embodiment of the mold panel of the present invention, and FIG. 4 shows a partially enlarged horizontal sectional view. As shown in the drawings, the molded panel of the present invention has a two-layer structure in which an inner plate 1 made of copper alloy and a back plate 2 made of non-magnetic stainless steel are stacked and bonded together. bolt 4
It is similar to a conventional molded panel in that the connected state is maintained by a nut 6 screwed thereon, but the bolt 4 erected on the inner plate 1 is erected by arc stud welding, while Grooves 7 forming cooling water channels A are provided on the back plate 2 side, and furthermore, all of the bolt through holes 5 provided in the back plate 2 do not interfere with the welded parts 8 raised along the bolt bases. This panel differs from the conventional mold panel shown in FIGS. 1 and 2 in that the inner plate side has stepped holes with a larger diameter. Figure 5 shows the inner plate 1, and Figure 6 shows the back plate 2.
are shown in perspective views, and FIG. 7 shows an enlarged sectional view of the bolt through holes 5 of the back plate 2. The welding of the bolts 4 to the inner plate 1 is described in Japanese Unexamined Patent Application Publication No. 1986-55.
This was done by the arc stud welding method described in Japanese Patent No. 141382. That is, as the copper alloy inner plate 1, a plate material made of a precipitation hardening copper alloy having the composition, electrical conductivity, and plate thickness shown in Table 1 is heated at a temperature of 925 to 975°C. 0.5 to 4 at specified temperature

The test was carried out under the conditions of 1050 to 1250 A and a current application time of 0.15 to 0.35 seconds. As a result, no weld heat affected zone was observed on the inner surface of the inner plate. In the molded panel of the present invention having the above-mentioned structure, the thickness of the inner plate 1 is reduced by vertically welding the bolts 4 to the inner plate 1 by arc stud welding, and the thickness of the inner plate 1 is reduced to 5. ~25mm, it is possible to maintain sufficient mechanical strength, and a small-capacity electromagnetic coil can provide a large electromagnetic stirring effect, especially when the inner plate 1 is made thinner. Since the cooling capacity is thus greatly improved, the casting speed can also be increased. As is clear from the above description, the mold panel of the present invention is useful for the economical production of continuous casting molds, and can significantly reduce running costs, making it possible to streamline slab manufacturing. Has excellent advantages.
