Silicocalcium SK15, SK20, SK30 GOST is a ferroalloy used in metallurgy for deoxidation of steels and alloys, as well as as a degasser, desulfurizer and modifier of cast iron. It consists of 60-65% silicon, 28-35% calcium, and also contains up to 5% iron. The specific content of chemical elements depends on the brand and is regulated by GOST-4762-71.
Silicocalcium is a complex deoxidizer of steels and alloys, an active degasser of cast iron. In metallurgy, it is valued for the fact that it can be used in furnace and out-furnace processing of alloys. It increases the quality of steel, its strength and ductility, but does not change the physico-chemical properties. Silicocalcium is the basis for modifiers and steel ligatures together with titanium, magnesium, vanadium, barium, aluminum and other metals. Various combinations of ligatures are used for the manufacture of alloys with specified characteristics:
In combination with vanadium, silicocalcium increases the strength of steel assemblies and parts at low temperatures without reducing the impact strength.
The additive with barium cleans the alloys from sulfur, increases the mechanical strength and ductility of the metal.
In the composition with zirconium — significantly increases the resistance of steel to cracks, as well as strength and hardness. The metal can be used in conditions of sudden temperature changes.
