Steel ladle working lining carbon-free corundum spinel precast block and preparation method thereof
The invention discloses a steel ladle working lining carbon-free corundum spinel precast block and a preparation method thereof. The refractory material is prepared from the following raw materials in parts by weight: 5-15 parts of white corundum with the particle size of 10-20 mm, 10-25 parts of tabular corundum particles with the particle size of more than 5 and less than or equal to 10 mm, 10-20 parts of tabular corundum particles with the particle size of more than 3 and less than or equal to 5 mm, 10-15 parts of tabular corundum particles with the particle size of more than 1 and less than or equal to 3 mm, 10-20 parts of tabular corundum particles with the particle size of less than or equal to 1 mm, 0-10 parts of tabular corundum powder with the particle size of 0.074 mm, 10-15 parts of sintered alumina-magnesia spinel with the particle size of 0.074 mm, 2-5 parts of active alpha-Al2O3 micro powder with the particle size of 2.5 microns and 2-5 parts of calcined alpha-Al2O3 micro powder 5 to 15 parts of yttrium oxide stabilized barium aluminum zirconate cement, 0.1 to 0.2 part of water reducing agent and 0.05 to 0.1 part of explosion-proof fiber. The refractory material is excellent in slag corrosion resistance, thermal shock resistance and high-temperature performance.
