Melting period: melting of steel mainly for the purposes of open-hearth and electric furnace steelmaking. Zhejiang steelmaking deoxidizer. EAF charge from the energization start to melt all clear so far from open hearth to the charge against the hot metal finish all of finish far have said melting period. Melting of the charge as soon as the task is melted and heated, and make good melting of the slag. Steelmaking slag process: adjustment operations steel, iron slag chemical production, alkalinity and viscosity and response capacity. Steelmaking deoxidizer. The purpose is through the slag - metal reaction has been refining the requirements issued by the composition and temperature of the metal. For example BOF slag and blowing operation is to generate sufficient liquidity and alkalinity of slag to the sulfur, phosphorus dropped below steel cap plan, and when blowing slag splashes and overflow volume is minimized.
