1.premelting refining slag 2.mainly used for calcium furnace of steel mill, LF converter ladle refining

Features and Main Application:

Calcium Aluminate  (Pre-melting Refinning Slag) has the characteristics of uniform ingredient, low melting pointing, fast melting speed, low impurities, shortening melting time etc. it can reduce the consumption of alloy during deoxygenation and alloying process, quicken slagging speed, inprove mechanics condition of desulfurization, inprove desulfurization effects, decrease hydrogen content in steel , improve lining life span, decrease pollution and refining cost.
