(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
