Fireproof spraying coating for steel ladle working lining and preparation method of fireproof spraying coating
The invention relates to a fireproof spraying coating for a steel ladle working lining. The fireproof spraying coating is prepared from the following raw materials in parts by weight: 20-50 parts of sintered bauxite clinker, 10-20 parts of fused magnesite, 8-20 parts of fused magnesia-alumina spinel, 5-12 parts of fused white corundum, 5-10 parts of active alumina micropowder, 3-10 parts of andalusite, 3-7 parts of silicon dioxide micropowder, 2-5 parts of a sintering agent, 0.1-0.2 part of externally added explosion-proof fibre, and 0.1-0.3 part of an externally added compound water-reducing agent. The fireproof spraying coating disclosed by the invention is simple in preparation method and simple and convenient to construct; rapid construction maintenance and rapid use of the steel ladle working lining can be realized; because of being compounded by adopting a carbon-free material, the fireproof spraying coating is environment friendly and free from pollution; therefore, molten steel can be purified effectively; the characteristics of high-temperature molten steel to the steel ladle working lining, such as washing resistance, slag corrosion resistance, thermal shock resistance and product comprehensive benefits, can be sufficiently improved; and the service life of the steel ladle working lining can be increased and prolonged effectively.
