Blast furnace iron runner skimmer suitable for oscillating sintering and preparation method of blast furnace iron runner skimmer
The invention discloses a blast furnace iron runner skimmer suitable for oscillating sintering. The blast furnace iron runner skimmer comprises the following raw materials in percentage by mass: 18-25% of brown fused alumina aggregate with the particle size of 5-8mm; 18%-25% of brown fused alumina aggregate with the particle size of 3-5 mm; 10%-18% of brown fused alumina particles with the particle size of 1-3 mm; 8%-15% of compact corundum particles with the particle size of 0.074-1 mm; 5-9% of dense corundum fine powder with the particle size of less than or equal to 0.074 mm; 6%-12% of silicon carbide particles with the particle size of 0.074-1 mm; 6-12% of silicon carbide fine powder with a particle size of less than or equal to 0.074 mm; 0.5%-3% of spherical asphalt with the particle size of 0.1-0.8 mm; 3%-6% of submicron SiO2 micro powder with the particle size being smaller than or equal to 0.020 mm; 2%-7% of alpha-Al2O3 micro powder with the particle size of less than or equal to 0.020 0.5%-1.0% of boron oxide powder with the particle size being smaller than or equal to 0.044 mm; by redesigning the formula, the raw materials of the blast furnace iron runner skimmer are well matched with oscillation sintering, and the obtained product is good in high-temperature performance, high in volume stability, excellent in erosion resistance, long in service life and low in comprehensive operation and maintenance cost and has remarkable economic and social benefits.
