Chrome corundum composite brick for hazardous waste incinerator rotary kiln and preparation method of chrome corundum composite brick
The invention discloses a chromium corundum composite brick for a hazardous waste incinerator rotary kiln, which comprises a heavy part and a light part, wherein the heavy part adopts chromium oxide,sintered corundum, fused corundum, mullite and activated aluminum oxide micro powder, the light part adopts light corundum aggregate and composite light burning powder, and the heavy part and the light part are sintered at high temperature to form a light and heavy integrated brick body. The light part serves as a thermal insulation layer, and the heavy part serves as a working layer. The invention also discloses a preparation method of the corundum composite brick. Compared with conventional corundum bricks and insulating bricks, the corundum composite brick prepared by the method has the advantages that the technical performance is stable, the effective working thickness of the working layer is relatively increased under the condition that the total thickness is not increased, and the service life is prolonged.
本发明公开了一种危废焚烧炉回转窑用铬刚玉复合砖，包括重质部分和轻质部分，重质部分采用氧化铬、烧结刚玉、电熔刚玉、莫来石和活性氧化铝微粉，轻质部分采用轻质刚玉骨料和复合轻烧粉，重质部分和轻质部分通过高温烧结形成轻重质一体化的砖体。轻质部分作为保温层，重质部分作为工作层。本发明还公开了此种刚玉复合砖的制备方法。采用本发明方法制得的刚玉复合砖技术性能比以往的刚玉砖与保温砖具有稳固的结构，在不增加总厚度的情况下相对增加了工作层的有效工作厚度，延长了使用寿命。
