Monolithic castables for ladle safety lining are composed of corundum, high quality bauxite, superfine powder and other ingredients and featured with good work ability on site casting, high strength, high volume stability and long life span.
Main raw materials of Ladle Working layer gunning mix are corundum and magnesium aluminate spinel, after spraying use on the working layer surface in carbon-free ladle.
Fused alumina, magnesium aluminate spinel, fused MgO and graphite are the main raw materials in use for Low carbon corundum-spinel brick. Low carbon corundum-spinel bricks, featured with high strength, better corrosion resistance and thermal shock resistance, are mainly used in the bottom and sidewall for low and ultra-low carbon steel production.
