Effect of the metal charge mass and the slag thickness on the process of steelmaking in an arc furnace

The effect of the metal charge mass and the foamed slag thickness on the sulfur, phosphorus, nitrogen, and hydrogen contents in a metal produced in a 120-t arc steel-melting furnace is studied. It is shown that the sulfur and nitrogen contents in the steel increase and the phosphorus and hydrogen co...

Zusammenfassung:The effect of the metal charge mass and the foamed slag thickness on the sulfur, phosphorus, nitrogen, and hydrogen contents in a metal produced in a 120-t arc steel-melting furnace is studied. It is shown that the sulfur and nitrogen contents in the steel increase and the phosphorus and hydrogen contents decrease as the metal charge mass increases or the slag thickness (mass) decreases.
