The role and use of refractory ball
The refractory ball is made of industrial alumina and refractory kaolin as the main raw materials, and is scientifically formulated, shaped and calcined at high temperature. It is especially suitable for high and low temperature shift furnaces, reformers, hydroconverters, desulfurization tanks and methanation furnaces in chemical fertilizer plants. It plays the role of dispersing gas and liquid, and supporting, covering and protecting catalysts. Refractory porcelain balls can also be used in hot blast stoves and heating transformation equipment in the steel industry.
Refractory ball properties:
High mechanical strength and long service life;
Good chemical stability, no chemical reaction with materials;
High temperature resistance, the maximum heat resistance temperature of refractory ceramic balls can reach 1900 degrees.
Classification and application of refractory ball:
The refractory ceramic balls are divided into ordinary refractory balls and high-alumina refractory balls. The ordinary refractory balls are suitable for converters and conversion furnaces in the sulfuric acid and fertilizer industries. The high-aluminum refractory balls are suitable for hot air furnaces and heating conversion furnaces in urea, steel and other industries.

The refractory ceramic balls are divided into ordinary refractory balls and high-alumina refractory balls. The ordinary refractory balls are suitable for converters and conversion furnaces in the sulfuric acid and fertilizer industries. The high-aluminum refractory balls are suitable for hot air furnaces and heating conversion furnaces in urea, steel and other industries. At present, the main problem encountered with the use of refractory balls is that high-alumina refractory balls have high hardness and brittleness. Dry grinding is easy to cause cracking of the ball stone and craters on the surface of the ball stone, resulting in very high wear. Before polishing the ball stone, pick out the ball stone with high cracking or wear.
