High-density chromium-zirconium-corundum brick for hazardous waste disposal rotary kiln
The invention discloses a high-density chromium-zirconium-corundum brick for a hazardous waste disposal rotary kiln, and belongs to the field of refractory materials. The chromium-zirconium-corundum brick comprises the following components in percentage by weight: 1-10% of chromium oxide with the particle size of less than or equal to 3mm; 1-10% of zirconium oxide with a particle size of less than or equal to3mm; 5-15% of alumina micro powder with a particle size of less than or equal to 0.004mm; 1-5% of a binding agent; and the balance of corundum with the particle size of less than or equal to 8mm. The chromium-zirconium-corundum brick is prepared by mixing the raw materials according to the required ratio, preparing a pug in a mixing mill, performing molding under the pressure of more than or equal to 400 tons, and sintering a green brick in a tunnel kiln or a shuttle kiln at 1500-1800 DEG C after molding. The chromium-zirconium-corundum brick has the advantages that the chromium-zirconium-corundum brick is suitable for various specifications of rotary kilns for hazardous waste disposal, the service life of the product can reach more than 6 months, and the chromium-zirconium-corundum brick plays a very positive role in improving the operation rate of the rotary kilns for hazardous waste disposal.
一种危险废物处置回转窑用高致密铬锆刚玉砖，属于耐火材料领域。铬锆刚玉砖按重量百分比各组份为：粒径≤3mm的氧化铬：1～10％；粒径≤3mm的氧化锆：1～10％；粒径≤0.004mm氧化铝微粉：5～15％；结合剂：1～5％；余量为粒径≤8mm的刚玉；将上述原料要求配比混合，于混炼机中制成泥料，在≥400吨的压力下成型，成型后砖坯于1500～1800℃的隧道窑或者梭式窑内烧成。优点在于，适用于各种规格危险废弃物处置用回转窑，产品使用寿命可达到6个月以上，对提高危险废弃物处置用回转窑运转率起到了非常积极的作用。
