Magnesia-carbon bricks are produced using high-purity high-alumina bauxite, high-purity and high-density fused magnesia, and high-purity graphite as main raw materials, adding appropriate amounts of antioxidants, with phenolic resin as the binder, and formed under high pressure using a 2500-ton fully automatic hydraulic press. The product is used as a working lining material in ladle walls and bottoms, directly contacting molten steel, offering advantages such as high strength, excellent resistance to mechanical abrasion, good thermal shock stability, and high refractoriness.
