Aluminum oxide （Al2O3）
Calcium slag, slag using method of aluminothermic reduction to produce metal Calcium , the main component is calcium aluminate, mainly used in LF furnace, open hearth furnace, converter steel ladle refining, removing sulfur, oxygen and other impurities in molten steel, reducing steel The content of harmful elements and impurities is suitable for ordinary carbon steel, high carbon steel, high and low alloy steel.
Calcium slag, slag using method of aluminothermic reduction to produce metal Calcium , the main component is calcium aluminate, mainly used in LF furnace, open hearth furnace, converter steel ladle refining, removing sulfur, oxygen and other impurities in molten steel, reducing steel The content of harmful elements and impurities is suitable for ordinary carbon steel, high carbon steel, high and low alloy steel.Main usage scenarios:
(1) High-grade special steel, requiring low titanium and low silicon. Such as: bearing steel, spring steel, etc.
(2) Hot metal pretreatment high-efficiency refining agent to replace the current CaO-CaF2 system
(3) RH vacuum addition of high-efficiency desulfurization and inclusion adsorption
(4) Ultra-pure ferritic stainless steel VOD reduction slag
(5) LF furnace slagging agent
