What should I do if my alumina hollow ball bricks are cracked? Alumina hollow ball bricks may crack during production. Many people don't know what to do in this situation. Today, the editor of Zibo Heyi Insulation Materials Co., Ltd. will explain this problem to you.
Generally, alumina hollow ball bricks will develop a thick layer of cracks after prolonged use. Therefore, it is required to reduce the pouring temperature and pouring speed during use. At low pouring temperatures, the shrinkage and wear of the alumina crucible can be reduced. During the smelting process, oxygen removal measures are taken to improve its function, resulting in better density. At the same time, cold iron is placed in the hot zone. After pouring, the hot blinding agent is placed at the riser of the corundum crucible to solve the problem of cracks in alumina hollow ball bricks.
The above is the solution to the cracking of alumina hollow ball bricks compiled by the editor of Jiaozuo Shiheng. Hope it can help you.
