Dolomite refractory brick
The invention discloses a dolomite refractory brick, relating to the technical field of manufacturing of refractory materials. The dolomite refractory brick is prepared from the following raw materials in parts by weight: 60-70 parts of dolomite fine powder, 10-15 parts of pyrophyllite powder, 20-30 parts of magnesite and 8-15 parts of paper pulp. The dolomite fine powder is prepared by carrying out high-temperature calcination and pulverization on dolomite. The dolomite refractory brick is prepared by the following steps: proportioning, mixing, making the blank, drying, and firing to obtain the dolomite refractory brick. Compared with the prior art, the dolomite refractory brick does not shrink at high temperature, does not rupture under the condition of extreme changes in temperature, has the advantages of high acid/alkali erosion resistance and long service life, and can not be damaged due to acid/alkali erosion.
