The use of vacuum smelting, casting billet without pores, subsequent processing does not peel; no grain boundary oxidation can ensure the good performance of the finished product; Compared with the traditional iron mold casting process, the segregation is small, the grain is fine and the microstructure is uniform. The weight of the ingot is 2 tons, the large billet ingot has greatly improved the yield of the finished product, the product is upgraded, and the tolerance, plate shape, and surface quality have been comprehensively improved.
