The charging method in electric furnace melting should put the carbon additive into the furnace along with the scrap steel and other furnace materials. For small-dose addition, it can be added on the surface of the molten iron. However, it is necessary to avoid putting a large amount of carbon additive into the molten iron at one time to prevent excessive oxidation and the situation that the carbon increase effect is not obvious and the carbon content of the castings is not enough. The amount of carbon additive added depends on the ratio and carbon content of other raw materials.
Different types of cast iron should choose different models of carbon additives according to needs. The characteristics of carbon additives themselves choose pure carbon-graphitized substances to reduce excessive impurities in pig iron. Choosing the appropriate carbon additive can reduce the production cost of castings.
