Chromium-free brick for RH inner lining and preparation method of chromium-free brick
The invention relates to a fireproof material and a preparation method thereof and in particular relates to a chromium-free brick for an RH inner lining and a preparation method of the chromium-free brick. The chromium-free brick for the RH inner lining is prepared from the following components in parts by weight: 15-18 parts of fused magnesite coarse particles, 20-25 parts of fused magnesite fine particles, 20-25 parts of fused magnesite fine powder, 2-5 parts of light calcined magnesia powder, 3-6 parts of alpha-alumina micro powder, 5-10 parts of aluminum-magnesium alloy, 10-15 parts of fused spinel powder, 10-15 parts of fused zirconium corundum and 3-5 parts of liquid phenol-formaldehyde resin. The chromium-free brick for the RH inner lining, prepared by the method provided by the invention, not only has a simple production method, but also has the characteristics of slug invasion resistance, high high-temperature strength, relatively high density and the like, and raw materials for preparing the brick do not contain chromium and are environmentally friendly, so that the comprehensive service performance of the chromium-free brick is superior to that of a magnesite-chrome brick.
