METHOD FOR controlling HEIGHT of formed foamed SLAG of STAINLESS ALLOY MELT in electric arc furnace

摘要

The invention relates to a method for controlling the foamed slag in a stainless melt in an electric arc furnace. According to the invention, the height of the slag in the electric arc furnace is thermographically detected continuously as a function of time and slag height and the addition of foaming material is controlled according to the temperature and the temperature gradient.
