Abstract

Изобретение относится к способу регулирования высоты получаемого вспененного шлака расплава нержавеющего сплава в электрической дуговой печи. Согласно изобретению, при этом высоту шлака в электрической дуговой печи непрерывно регистрируют термографически как функцию времени его образования и температуры в нем и в зависимости от температуры и температурного градиента регулирующие подачу пенообразующего материала.
