Refractory porcelain balls Refractory balls are made of industrial alumina and refractory kaolin as the main raw materials, through scientific formula, shaping and high-temperature calcination. nature
It has 1. high mechanical strength and long service life; 2. good chemical stability and no chemical reaction with materials; 3. good high temperature resistance, the maximum heat-resistant temperature of the refractory ceramic ball can reach 1900 degrees. It is especially suitable for use in high and low temperature conversion furnaces, reforming furnaces, hydroconverters, desulfurization tanks and methanation furnaces in fertilizer plants. It plays the role of dispersing gas and liquid, and supporting, covering and protecting catalysts. Refractory ceramic balls can also be used in hot blast furnaces and heating conversion equipment in the steel industry.

Product Feature:
Application:
Refractory porcelain balls are divided into ordinary refractory balls and high-aluminum refractory balls. Ordinary refractory balls are suitable for converters and conversion furnaces in the sulfuric acid and fertilizer industries. High-aluminum refractory balls are suitable for hot blast furnaces, heating conversion furnaces and other equipment in urea, steel and other industries.
