Application: 1、Regenerative burner bed applications Heat exchange media Properties: Spherical balls of alpha-alumina (corundum) is produced by sintering ball-formed calcined alumina at a temperature just under the 3704°F (2040°C) fusion point of aluminum oxide. Two kinds of  formation process: rolling and pressing . In the working process, alumina balls in the heat storage tank divide the air flow into very small flow strands, and the air flow forms strong thunderstorm when it flows in the heat conduction body, which can effectively absorb the heat on the surface of the heat conduction body, so the regenerative burner can be changed frequently and quickly.After the high temperature gas flows through the regenerator, the temperature can rise to only about 100℃ lower than the flue gas temperature, and the temperature efficiency is more than 90%. Advantages: The corundum alumina ball is made of industrial alumina as the main raw material. It has the characteristics of low shrinkage, high temperature load softening temperature, corrosion resistance, high strength, large heat storage and discharge, good thermal shock stability, good thermal conductivity and small number of thermal expansion. Appearance: White crystalline gravel or ball. Depending on requirements, ball sizes are produced from 1/8 to 2 inch (tolerance ± 6% mm)。

Application: Widely used in petroleum,chemical industry,chemical fertilizer,natural gas,environmental protection and other fields,as the catalyst in the reactor cover support materials and tower filler,The main effect  is to increase the distribution of gas or liquid, to support and protect low strength active catalysts. Properties: With high temperature and high pressure resistance,low water absorption,chemical stability,acid and alkali resistance,resistance to organic solvent corrosion, the balls can with stand the temperature changes in the production process.High purity, high strength, high temperature resistance, high pressure resistance, strong acid and alkali corrosion resistance, thermal shock stability, chemical stability characteristics.
