What material should be selected for the long-life hazardous waste disposal rotary kiln lining brick
Several typical refractory materials used in hazardous waste disposal rotary kilns are chromium zirconium corundum 50 bricks, chromium zirconium corundum 30 bricks, chromium corundum bricks, high alumina bricks , corundum mullite bricks and aluminum chromium silicon carbide bricks at 1100 and 1300 ℃ respectively. Anti-corrosion performance of slag. The results showed that: 1. After the corrosion test at 1100℃, the 6 groups of samples all showed good corrosion resistance and anti-permeability performance, and a large amount of slag remained in the crucible after the test. 2. After the corrosion test at 1300 ℃, the slag erosion and penetration behavior of the 6 groups of samples were significantly increased. The chromium zirconium corundum 50 brick still maintains excellent corrosion resistance, but the slag penetration phenomenon occurs; the chromium zirconium corundum 30 brick and the chromium corundum brick are slightly corroded, and the degre...
