Preparation method of forsterite refractory brick
The invention discloses a preparation method of a forsterite refractory brick, relating to the technical field of manufacturing of refractory materials. The forsterite refractory brick comprises the following raw materials in parts by weight: 70-80 parts of foresterite, 15-25 parts of magnesium carbonate, 15-20 parts of magnesium oxide and 10-15 parts of paper pulp. The preparation method comprises the following steps: proportioning, compounding, blank making, drying and firing to obtain the forsterite refractory brick. Compared with the prior art, the forsterite refractory brick prepared by the method has the advantages of high refractoriness under load and favorable heat stability, can not shrink at high temperature, is used as a liner material of a forging heating furnace or cement kiln, can not have crack damage due to shrinkage at high temperature, and prolongs the service life of the liner of the forging heating furnace or cement kiln.
