Chrome corundum castable for hazardous waste rotary kiln
The invention discloses a chrome corundum castable for a hazardous waste rotary kiln, and belongs to the technical field of refractory castables for hazardous waste incineration rotary kiln treatmentsystems. The chrome corundum castable comprises corundum, electric smelting chromium sesquioxide, chromium sesquioxide micro powder, aluminum oxide micro powder, silicon dioxide micro powder, pure calcium aluminate cement, additives and the like. The granularity and the mass percent of each raw material are as follows: 60-80% of corundum with the granularity of less than or equal to 8mm, 0-10% ofelectric smelting chromium sesquioxide with the granularity of less than or equal to 1mm, 0-10% of chromium sesquioxide micro powder with the granularity of less than or equal to 5mu m, 1-10% of silicon dioxide micro powder, 1-10% of aluminum oxide micro powder and 2-10% of pure calcium aluminate cement; the castable also comprises 0.02-0.5% by mass of an additive, wherein the additive is one or more of sodium tripolyphosphate, sodium hexametaphosphate, sodium lignin sulfonate or polycarboxylic acids. The chrome corundum castable has the advantages of high strength, good wear resistance, gooderosion resistance, good permeation resistance and the like.
