Refractory porcelain ball is made of industrial alumina and refractory kaolin as the main raw materials. It is made by scientific formula, molding and high-temperature calcination. It has high mechanical strength, long service life, good chemical stability, and no chemical reaction with materials; Good high-temperature performance, the highest heat-resistant temperature can reach 1900 degrees. It is especially suitable for high and low temperature shift furnaces, reformers, hydrogenation reformers, desulfurization tanks and methanation furnaces in chemical fertilizer plants, and plays the role of dispersing gas and liquid, and supporting, covering and protecting catalysts. It can also be used in hot blast stoves and heating conversion equipment in the iron and steel industry.
