It is for preventing volume expansion of the slag in the steelmaking process during solidification.Slag anti-powdering agent helps to reduce the slag to be the powder and the dust in the hot
steel.
Overview
Silicon carbide briquettes are produced for use in cupola melted gray and ductile base iron for the purpose of introducing silicon and carbon to the iron. The advantage silicon carbide holds over
ferrosilicon products is the addition of a carbon component which may provide carbon units to the iron and /or reduce cupola coke requirements, The reduction in coke may in turn lead to increased
melt rate.
