Magnesite-spinel brick for RH inner liner and preparation method of magnesite-spinel brick
The invention relates to a fire-proof material and a preparation method of the fire-proof material, in particular to a magnesite-spinel brick for an RH inner liner and a preparation method of the magnesite-spinel brick. The magnesite-spinel brick for the RH inner liner is prepared from the following ingredients in parts by weight: 15 to 18 parts of fused magnesite coarse particles, 20 to 25 parts of fused magnesite fine particles, 20 to 25 parts of fused magnesite fine powder, 2 to 5 parts of TiAl3 powder, 3 to 6 parts of alpha-aluminum oxide micro powder, 5 to 10 parts of metallic aluminum, 10 to 15 parts of fused spinel powder, 5 to 10 parts of fused magnesia-zirconia sand and 3 to 5 parts of liquid phenolic resin. The prepared magnesite-spinel brick for the RH inner liner has the advantages that the production method is simple; the characteristics of good slag corrosion resistance, high high-temperature intensity, higher compactness and the like are also realized; raw materials do not contain chrome; the environment is friendly; the comprehensive use performance is superior to that of a magnesia-chrome brick.
