Analysis on the Refractory Erosion of the Electric Arc Furnace and Study on the Measures of Protecting the Furnace Lining

The erosion situation of the refractories of the deep reduction electric arc furnace have been introduced firstly, including the regions such as furnace wall, tapping hole and slag hole, and analyzing on the causes of the erosion shows that high temperature, chemical erosion of oxides in slag, as well as physical scour are the main causes of the serious erosion to the lining. Based on the practical production conditions three solutions are provided including preventing oxidation of metallized pellets, control the temperature and carrying out hot-spray-mending on the furnace.
