Casting carburizer use requirements

Casting carburizer is a kind of additive used in steelmaking, which can greatly increase the amount of scrap steel and reduce the amount of pig iron or no pig iron.The use of carburizer in steelmaking can not only reduce the use of pig iron, but also increase the use of scrap steel.Carburizing agent is an essential material for steel production.

At present, the vast majority of carburizing agent is suitable for electric furnace melting, but also a small part of the absorption rate is particularly fast carburizing agent for cupola.The feeding mode of electric furnace melting, should be carburizing agent with scrap and other charges put in, a small dose of add can choose to add on the surface of hot iron.

However, it is necessary to avoid large quantities of feeding into the molten iron to prevent excessive oxidation and carburization effect is not obvious and the carbon content of the casting is not enough.The addition of carburizing agent, according to the ratio of other raw materials and carbon content to determine.Carburizing agent characteristics of its choice of pure carbon graphitization substances, reduce excessive impurities in pig iron, carburizing agent selection can reduce the casting production cost.

Casting steelmaking to steelmaking with carburizing agent requirements, low sulfur content, carburizing effect is stable, high carbon absorption rate.It can be used for carburizing cast steel and cast iron in various electric furnaces, bringing considerable economic benefits to production.But do you know what kind of carburizer is a good carburizer?The first is the appearance of carburizing agent, clean without impurities.
