Refining: the steel-making furnace (converter, electric furnace, etc.) over the beginning of the refining of molten steel to another container for Deoxidants price of refined steel-making process, also known as secondary metallurgy. So the steelmaking process into two steps early smelting and refining. First Lian: charge in an oxidizing atmosphere furnace melting, dephosphorization and decarbonization and the main alloying. Refining period: steel-making process through the slag and other methods of steel quality of some harmful elements and compounds Buy Deoxidants by chemical reaction into a gas phase or selected rows, floating into the slag, making it excluded from the liquid steel process operating period. Reduction of: General Power EAF steelmaking operations, usually finished late oxide slag to tapping this time called the reduction period. Its main task is to make reducing diffusion slag, deoxidation, desulfurization, control of chemical composition and adjust the temperature. Current high-power and ultra-power electric arc furnace operation has been canceled reduction period.
