How to use andalusite to make low creep agglomeration Mo Laishi brick

   Make aggregate with andalusite, silicon line stone makes the grain intermediate, the collective fine crocus of pink of aluminium powder of oxidation of pink of silicon line stone, aluminous pink, industry, clay makes matrix makings can be madeMake agglomerationMo Laishi brick. Its raw material deserves to fall for instance: Aggregate: Intermediate grain: Fine pink =50: 12: 38. In burden from compound bond, with 260t attrition is pressedBricky machine shapes. Drying of base substrate classics is divided at 1% to incomplete remains water, in loading blaze kiln, undertake firing. Firing temperature is 1490 ° C, heat preservation 19h, the gas of goodsAperture rate can be amounted to 17.15% , bulk density 2.53g/cm3, 136.5MPa of intensity of normal temperature compression, loading bate temperature 1627 ° C. 1450 ℃ , 50h creep is led butAmount to 0.87% . If firing temperature is 1450 ℃ , heat preservation time is lengthened to 26h, also can achieve the goal of agglomeration. But, physical function index is compared 1490The products index with firing ℃ is a few lower, for example 1450 ° C, 50h creep rate is 0.98% .
