Introduction of Refractory Ceramic Balls

Refractory ceramic balls are easy to replace and clean and can be reused.

The material of the refractory ball is divided into high alumina, corundum, and zirconium corundum.

There are many types of refractory balls, which can be used in high and low-temperature shifting furnaces, reforming furnaces, hydro converters, desulfurization tanks, and refractory balls and heating conversion equipment that are replaced by hot blast stoves in the steel industry.

Refractory ceramic balls have high strength and wear resistance; good thermal conductivity and heat capacity are excellent, and their heat storage efficiency is high; the thermal stability of the regenerative porcelain ball is good, in high-temperature room refractory ceramic balls can hold energy escaping when the temperature is drastically changed. The heat storage ball is especially suitable for the air separation equipment regenerator and the blast furnace gas heating furnace of the steel plant as the heat storage filler. The heat storage ball double preheats the gas and air, and the heat storage ceramic balls make the combustion temperature quickly reach the rolling steel to heat the steel slab.

The refractory ceramic balls with high alumina content, high density, high mechanical strength, good wear resistance, stable chemical properties, and excellent heat resistance, high-aluminum ceramic balls are widely used, can be used as chemical filler, high aluminum The porcelain ball can be used as a grinding medium. High-aluminum force.

Features of Refractory Ceramic Balls

Good chemical stability, no chemical reaction with materials.

High mechanical strength, wear resistance, and long service life.

Good high-temperature resistance, the highest heat resistance temperature can reach more than 1700 degrees.

The thermal conductivity and heat capacity is large, and the heat storage efficiency is high.

The thermal storage ceramic balls have good thermal stability and are not easy to break when the temperature changes drastically.
