Gute saving to provide you with the best performance of corundum castable plate corundum castable is a pure, do not add any additives such as MgO, B2O3, etc. firing shrinkage completely sintered alumina, with coarse crystalline Liaoning insulation castable, well-developed α-Al2O3 crystal structure. High melting point, about 2040 ℃; large grain hardness, Mohs hardness 9, Knoop hardness 2000; resistance to chemical attack, in addition to hydrofluoric acid and phosphoric acid, most of the alkali and mineral acids has no effect on the tabular alumina; because of its absence of microcracks and large internal pores, high strength; at the same time, heat impact strength decreased much, so good thermal shock resistance. Tabular alumina castable advantages: high refractoriness; high heat load strength, low creep; high-density, low permeability; thermal shock resistance, good abrasion resistance; low shrinkage; high purity, reduce impurities on the impact of high temperature material properties. Gute saving low cement castable, quality assurance low cement castable preparation process is very strict, so many factors that affect performance, mainly superfine, aluminate cement and admixture. Refractory aggregates and admixtures. Refractory aggregate and water consumption, is also an important factor. Ultrafine low cement castable role is to determine the pillars of low cement castable refractory series can also be no exaggeration to say insulating castable, no ultrafine Shanxi insulation castable refractory be no low cement series castable. In the low cement castable refractory, ultrafine dispersion major acts accelerator and structure dense agent. The former cement particles highly dispersed without flocculation, which microporous structure fully tamped and improve strength. Superfine types are SiO2, a-Al2O3, Cr2O3, ZrO2 and MgO, etc. SiO2 ultrafine powder specific surface area of ??about 20m2 / g, which after about 1/100 of cement particles, and therefore has a good dispersibility and filling. With the increase of the amount of Jilin ultrafine SiO2 insulation castable, increase strength, reduce refractoriness, the appropriate amount of ≥3%.
