Construction and Maintenance of 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 refractory materials used in the working layer are in direct contact with molten steel and slag. Directly withstand high-temperature heat load and erosion of molten slag, erosion of molten steel, mechanical impact of scrap steel, … Read more
