Alumina Regenerative Ball

The industrial alumina with more than 98% Al2O3 is melted in electric arc furnace, and the temperature of liquid material is 2200-2300 ℃, Blow the liquid away with compressed air, The air is wrapped in the air by the blown Al2O3 liquid. After cooling and solidification, the alumina hollow ball is formed. After collecting the blown ball, the finished product is obtained through sorting and screening. The crystal form of the product is α - Al2O3 microcrystal, with low impurity content, low density, low thermal conductivity and high mechanical strength. It is several times of that of ordinary light products, and the maximum service temperature is 1800 ℃. The product is a kind of refractory with high temperature resistance and excellent energy saving effect, with energy saving up to more than 40%. The product can be used for high temperature, ultra-high temperature insulation filler.
