At present the vast majority of Carburant apply to electric melting, but also a small number of particularly rapid rate of absorption by carbon-agent for the cupola. Carbon agent adding amount, according to other raw materials ratio and carbon content to be setted. Different types of cast iron, according to choose different models of increasing carbon dose. Carburant own choices characterized by pure carbon graphite material, to reduce impurities in pig iron too many years, increasing the carbon choose the right agent can reduce the casting cost of production...
