ramming material at the bottom of electric furnace

Knowledge about dry ramming material at the bottom of electric furnace

At present, the working layer of high-power and ultra-high-power electric furnaces is generally constructed with magnesia dry ramming material. The working layer uses refractory materials to directly contact molten steel and slag, and directly bear high-temperature thermal load and corrosion of molten slag, and erosion of molten steel and steel scrap. Mechanical impact and oxidation…
