Production method of industrial alumina ball

Making oxygen bai industrial alumina and is the main raw material of aluminum ball du, blowing through the fused method, zhi, on the basis of arc furnace electric melting equipment, through the use of graphite or other refractory masonry, we ought to be in the edge of build by laying bricks or stones first-class port, and then install the nozzle, the nozzle should be connected with compressed air device. We can tilt the furnace and use graphite as an electrode. We can add aluminum oxide powder in the molten pool and then use electricity to melt. When the temperature is more than 2200 degrees Celsius, it will be rolled. Under the condition of tilting the furnace, the solution will flow out. Compressed air will also spray the solution flow. Under different conditions of the viscosity and surface tension of the solution, if the solution is continuously blown and condensed, then it may form a ball enveloping the air. Only after we collect and screen it, can we store it in different particle sizes for standby use. The greater the pressure of the compressed air, the greater the number of alumina globules. The thickness of the oxide wall varies with particle size, and if the size range is 0.5 mm to 5 mm, it should be 0.1 mm to 0.3 mm thick. The natural bulk density of a hollow ball is inversely proportional to its particle size.
