More Information
Summary:The invention discloses a microporous magnesium-aluminum-chromium composite brick for a waste incineration rotary kiln and a preparation method of the microporous magnesium-aluminum-chromium composite brick. The microporous magnesium-aluminum-chromium composite brick is composed of 45-60% of magnesium-aluminum-chromium spinel sand, 15-30% of fused magnesia, 10-25% of high-purity magnesia fine powder, 1-5% of chrome green powder, 1-5% of SiC fine powder and 1-3% of PMMA microspheres. Uniformly mixing the high-purity magnesia fine powder, the chrome green powder, the SiC fine powder and the PMMA microspheres to obtain premixed powder; mixing the magnesium-aluminum-chromium spinel sand and the fused magnesia, adding the binding agent, continuously mixing, finally adding the premixed powder, uniformly mixing to obtain mixed pug, and molding the mixed pug into a magnesium-aluminum-chromium composite brick semi-finished product; and sequentially drying, sintering and cooling the semi-finished product to obtain the
