The alumina refractory ceramic balls uses industrial aluminum aluminum as raw materials, and is made of light oxide empty heart refractory ceramic balls made of light spray. The lightweight refractory warming tiles prepared by aluminum oxide empty heart ball can be used for high -temperature furnace lining of flames. So what are the characteristics and smelting technology of aluminum oxide? Henan 40 % Xiaobian answered for everyone.
Features of alumina refractory ceramic balls:
1. High use temperature: can reach 1750 degrees, good thermal stability. The change rate of heavy burning lines is small and longer.
2. Optimize the structure and reduce the weight of the furnace body: The current high-temperature resistance material is a heavy-quality brick volume density of 2.6-3.0g/cm. The aluminum oxide empty heart ball brick is only 1.1 ~ 1.5g/cm. The same cubic meter volume. The use of alumina empty heart refractory ceramic ball bricks can reduce the weight of 1.1-1.9 tons.
3. Save materials: The same temperature is achieved. If the price of heavy bricks is used as the price of aluminum oxide empty heart refractory ceramic ball bricks. And it also needs considerable insulation fire refractory materials. If the alumina empty heart brick is used, the amount of 1.1-1.9 tons of heavy tiles can be saved per cubic meter, and 80%can be saved by 80%.
4. Save energy: Aluminum oxide empty heart refractory ceramic ball has obvious insulation characteristics, low thermal conductivity coefficient, which can play a good thermal insulation effect. Reduce heat distribution, improve thermal efficiency, and play a purpose of saving energy. Energy -saving effect can reach more than 30%.
Production process of aluminum oxide empty heart ball:
1. Add the alumina raw material to the dumped arc furnace to melt into liquid.
2. Then pour the stove to a certain angle, so that the fuse flows out of the water pouring groove at a certain speed, and the flat nozzle with the liquid flow passes with the flow of 60 ° ~ 90 is stressed at a high -speed air current with a pressure of 0.6 ~ 0.8MPa. Blowing, that is, it becomes an aluminum oxide empty heart ball.
3. The characteristics and construction methods of aluminum oxide empty heart ball. The editor of the wholesale price manufacturer of aluminum alumina empty heart refractory ceramic balls below will give you a detailed introduction.
4. High temperature resistance of aluminum oxide empty heart refractory ceramic balls, good use efficiency, and due to the special structure, it can effectively reduce the weight in the furnace, the insulation effect of the aluminum oxide empty heart ball is significant Effects, before the construction of aluminum oxide empty heart ball, it must be cleaned up to achieve a better adhesion. You must use water when stirring. Master the time when stirring.
