At steel mills melt processing calcium solve a complex task: reduction of oxygen, sulfur, nonmetallic inclusions; modification of nonmetallic inclusions, improving the mechanical properties of the metal, improving castability on continuous casting machine AK steel, etc. Quantity of calcium absorption, morphology and composition of inclusions dependent changes in the concentration of aluminum, oxygen and sulfur in the melt in the case of administration of calcium metal in the form of a cored wire as well as the slag composition when administered alloys of calcium release from the steel making unit into a ladle. A method of entering into the metal to silicocalcium release of steelmaking unit in the steel ladle in aluminum containers glasses. Industrial data obtained, confirming the possibility of providing a sufficiently high and stable, in a particular shop, calcium absorption and its effective impact on the composition and physico-chemical state of the melt and the properties of the finished steel products.
