Description
Изобретение относитс к области черной металлургии и может использоватьс при раскислении стали.The invention relates to the field of ferrous metallurgy and can be used in the deoxidation of steel.
Известна лигатура, содержаща марганец, алюМИний, ванадий, , серу, фосфор, железо .A known ligature containing manganese, aluminum, vanadium, sulfur, phosphorus, iron.
Цель изобретени - повысить качество стали . Дл этого в состав лигатуры дополнительно введены кальций и ниобий при следующем соотношении компонентов, вес. %: Марганец60-80The purpose of the invention is to improve the quality of steel. To do this, calcium and niobium are added to the composition of the ligature in the following ratio of components, weight. %: Manganese60-80
