Problems solved by technology

The disadvantage is that the particle size of iron oxide is not fine enough, and the dispersion in the silica brick is not uniform enough; calcium oxide is actually added with calcium hydroxide, and its lime milk solution is easy to flocculate and difficult to disperse, so it is less effective as a mineralizer

Abstract

The invention relates to an aluminum silicon refractory. The refractory comprises an aggregate, a powder material and an admixture, wherein the aggregate comprises a kaolin, xenotime, zircon and silicon carbide; the powder material comprises ooze and bauxite micropowder; the admixture comprises a composite binding agent and a composite mineralizer. The aluminum silicon refractory has good high temperature resistance, erosion resistance, wear resistance and low heat conductivity, has good mechanical properties, heat stability and heat shock resistance, reduces heat dissipation loss, is safe andnon-toxic, and is an environment-friendly material, so that the refractory has a good toughening effect, the medium temperature strength, the high temperature strength, the heat shock resistance andthe slag erosion resistance of the refractory are significantly improved, the service life is prolonged, and economic benefits are increased.

Description

technical field [0001] The invention belongs to the field of refractory materials, in particular to an aluminum-silicon material with high temperature resistance, corrosion resistance, thermal shock resistance, wear resistance and low thermal conductivity, which improves the high temperature resistance, alkali corrosion resistance and thermal shock resistance of refractory materials refractory material. Background technique [0002] Silica bricks are made of high-quality special-grade high-alumina bauxite and silicon carbide as the main raw materials, and are often mixed with special refractory materials such as corundum, mullite, andalusite, and alumina micropowder. Silica bricks mainly rely on the physical and chemical properties of silicon carbide to obtain good performance. The high thermal conductivity of silicon carbide endows silica molybdenum bricks with good thermal shock resistance; the high hardness of silicon carbide endows silica molybdenum bricks with better w...
