The basic requirements for the recipe of the induction furnace ramming material for the ingredients:

1. Accurate ingredients: Inaccurate ingredient weights can easily lead to improper control of chemical composition in the smelting process or insufficient casting of castings, and excessive amounts may increase consumption. Inaccurate distribution of the chemical components of the ramming material will bring difficulties to the smelting operation, and in severe cases will make the smelting impossible. Generally, the ingredients are based on the type of steel smelted, equipment conditions, existing raw materials and different smelting methods.

2. The principle of using ramming material for melting steel: The principle of using ramming material for melting steel mainly considers the charging method, smelting method, the chemical composition of the steel grade, and the quality requirements of the product.
