Casting Technology of 42CrMo4 Steel

There are two mainstream methods for 42CrMo4 smelting and casting, one is electric arc furnace smelting, secondary refining and vacuum degassing, and the other is converter steelmaking and continuous casting technology adopted by large steel mills.

The difference is that electric arc furnace steelmaking is suitable for small batch production, and the composition of molten steel is greatly affected by scrap steel. Converter steelmaking is suitable for mass production, and the purity of molten steel is high. Compared with electric arc furnace steelmaking, the smelting cycle is shorter and the power consumption is lower.
