Converter magnesia carbon bricks refer to magnesia-carbon refractory products made of magnesia graphite as main raw materials for converter lining. The main raw materials are fused magnesia high-purity sintered magnesia high-purity graphite. Generally, it is required that MgO in magnesia is greater than equal to 95%, the content of C in graphite is greater than equal to 94%. Use phenolic resin asphalt as binder, appropriate additives according to the conditions of use, make finished products after batching, kneading, molding, heat treatment.
