High-density chrome corundum brick for hazardous waste disposal rotary kiln
The invention discloses a high-density chrome corundum brick for a hazardous waste disposal rotary kiln, and belongs to the field of refractory materials. The chrome corundum brick comprises the following components in percentage by weight: 1-20% of chromium oxide with the particle size of less than or equal to 3mm; 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, wherein Al2O3 is greater than or equal to 94%. The chrome 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 chrome corundum brick has the advantages that the chrome 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 chrome 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刚玉砖，属于耐火材料领域。铬刚玉砖按重量百分比各组份为：粒径≤3mm的氧化铬：1～20％；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：其中Al2O3≥94％；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。
