The basic requirements of induction furnace ramming materials for ingredients
The basic requirements of induction furnace ramming materials for ingredients:
Accurate ingredients: Inaccurate ingredient weights can easily lead to improper chemical composition control 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.
The accuracy of the ingredients includes two aspects: the weight of the ramming material and the ingredients of the ingredients. We have many years of experience in induction furnace ramming materials. Take oxidation smelting as an example. If the carbon content is too high, it will increase the amount of ore or extend the oxygen use time; if the carbon content is too low, it will definitely be melted. Carry out carbon increase; if the S and P in the ramming material are too high, it will bring difficulties to the operation in front of the furnace, which not only prolongs the smelting time, but also corrodes the furnace lining seriously, and sometimes even terminates the smelting. In order to prevent the above situation, it is very important to know the chemical composition of steel materials and cast iron materials before batching.
