DEOXIDISER FOR STEEL Russian patent published in 2017 - IPC C21C7/06

Abstract RU 2638470 C1

FIELD: metallurgy.

SUBSTANCE: deoxidizer for steel contains, wt %: calcium carbide 40-55, calcium oxide 20-38, aluminium oxide 12-25 and impurity compounds 3-10 at concentration ratio of calcium oxide to the concentration of aluminium oxide 1-2.5 and is homogeneous alloy of calcium carbide CaC₂with a low-melting flux system CaO*Al₂O₃.

EFFECT: invention allows to increase the degree of deoxidiser assimilation with steel oxygen with simultaneous development of processes of desulphurisation and removal of nonmetallic inclusions formed by free-running liquid of lime-alumina slag.
