company news about About chrome brick

Dense chrome oxide bricks to isostatic pressing for E glass and C glass tank furnace side wall, neck or other serious erosion area, life of up to 6 ~ 7 years. Chromium containing products in recent years has made new progress, such as joining in the AZS Cr2O3 formation of Al2O3-ZrO2-SiO2-Cr2O3  refractory brick materials at high temperature, Cr2O3, on the one hand and the formation of Al2O3 solid solution, on the other hand, because the Cr2O3 is a high melting point material into the brick, glass increased the viscosity of the glass phase, thus improving the exudation temperature of glass phase the glass products, glass erosion resistance is greatly improved. USA a company to produce a combined with fused cast AZS/Cr2O3 refractories, its chemical composition and physical properties are superior, compared with the original used Al2O3/Cr2O3 materials, reducing the power consumption of the 4 year period of furnace, the production increased 15, the cost is reduced by 3.75, the glass quality is not affected, the brick can machine pressure molding, manual tamping play shaping or isostatic pressing, and then high temperature sintering.
