Common Issues During the Installation of Magnesia-based Dry Vibratable Mixes for Tundishes

The working lining of the tundish comes into direct contact with molten steel; therefore, it is required to reduce inclusions in the melt, enhance steel purity, and exhibit strong resistance to erosion by molten steel and slag. Additionally, it should facilitate extended casting times for thin-slab continuous casting and allow for easy dismantling after use … Read more

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
