A refractory ball is a kind of sphere made of industrial alumina and refractory kaolin as the main raw materials and calcined at high temperatures with a scientific formula. It is mainly divided into high alumina refractory balls, silicon refractory balls, magnesium aluminum refractory balls, porcelain balls, etc. It is suitable for converters and shift furnaces in the sulfuric acid and fertilizer industries, and high-alumina refractory balls are suitable for hot blast stoves, heating shift furnaces, and other equipment in urea, steel, and other industries.

The main function of the refractory ball in the actual use process is that it has good high-temperature resistance and high hardness. Putting the refractory ball evenly into the heating furnace can evenly distribute the gas, and the uniformly dispersed gas can reduce the impact on the gas. The role of the catalyst prolongs the service life of the catalyst, and at the same time, it has high hardness, so it can support the heating object in the heating furnace.

the Functions of Refractory Balls

The working principle of the refractory ball is to divide the airflow into small streams by many small balls. The airflow flows through the heat storage body for a period of time, forming a fierce turbulent flow, which effectively breaks through the boundary layer on the surface of the heat storage body. Small size, small conduction radius, small thermal cathode, high density, and good thermal conductivity, so it can meet the requirements of frequent and rapid reversing of regenerative burners.

We use more high-alumina refractory balls in the process of use. Although the high-alumina refractory balls are very hard, they also become very brittle after high temperatures. It leads to a phenomenon of very high wear, so we must pick out the balls with high cracking and wear in the actual use process.
