open hearth steelmaking
Molecular formula :
MW :
CAS :

nature : gas or heavy oil as fuel, used in flame will open hearth furnace pig iron and steel scrap and other raw materials and furnace while loading of ore, limestone and other agents and oxygen flux direct heating, melting and refining of liquid refining folk Steel methods. The 20th century from 30 to 50 years has been the world's most important method of steelmaking has been gradually oxygen furnace and converter replaced by the law. Smelting process normally takes fettling, filling, heat, hot metal was melting, refining, and steel deoxidation steps. According to the steel compound used by pig iron (or hot metal) and scrap laws and carbon Act. A blast furnace hot metal supply with the general law and scrap ore ratio can be divided into different ore, scrap ore, scrap ore, scrap the cheapest places Scrap common law.
