Abstract: PROBLEM TO BE SOLVED: To prevent the generation of warpage and deformation in a electrode plate even when a cell main body is contracted by making one end of an electrode plate part arranged in the cell main body having an inside space a non- constraint end which is not constrained by the cell main body. SOLUTION: When an electroconductive body 15 is arranged on a second mold 20 so that the end surface 15c of an electrode plate 15a contacts a step 20a formed in the mold 20, and a first mold 21 is mounted on the second mold 20, the conductive part 15b of the body 15 passes through an opening formed in the first mold 21. After that, a space 22 is filled with a molten resin, the resin is cooled to obtain a part in which a lid 13 is molded integrally with the body 15. Due to a large thermal expansion coefficient of the resin, the length L' of the produced lid is shorter than the length L of the space 22. However, since a thermal expansion coefficient of metal is by far smaller as compared with the resin, the length 1 of the electrode plate 15a indicates no substantial change even after a cooling process, preventing the warpage of the plate 15a.

Title: Method for preventing surface crack at the time of continuously casting ni-containing steel
Inventor: KATO TORU
IPC: B22D11/124
Filed: 1994-06-23
Abstract: PURPOSE:To restrain the surface cracking and to improve the quality and the yield of a cast slab by controlling the cooling so that the surface temp. of the cast slab in a secondary cooling zone does not exceed a specific temp., in the continuous casting of a steel containing a specific range of Ni. CONSTITUTION:In the continuous casting of the steel containing 0.1-50wt.% Ni, the cooling is controlled in the secondary cooling zone so that the surface temp. of the cast slab does not exceed 1200 deg.C to restrain the oxidation in the grain boundary on the surface part of the cast slab. When the surface temp. of the slab becomes >=1200 deg.C in the Ni-containing steel, Fe2SiO4 is melted and thus, the oxidation in the grain boundary is made to be remarkable and the traverse crazing crack is easily developed. Further, even if the contents except Ni are varied, oxidized scale form is not observed to large variation. Therefore, in the objective steel in this case, the contents of component elements except Ni is not necessary to limit. By this method, the surface cracking, such as traverse-crazing crack, developed on the surface of the cast slab is restrained at the time of continuously casting the Ni-containing steel.
