Hot Blast Stove Regenerator High Alumina Refractory Balls with Al2O3 Content ≥55

Description of Thermal Storage refractory balls

Refractory ceramic ball has the characteristics of strong oxidation resistance and slag resistance.Refractory ceramic ball is easy to replace and clean and can be reused.

Main specifications of refractory ball: Φ40mm Φ50mm Φ60mm Φ70mm

The material of Refractory ceramic ball is divided into high alumina, corundum and zirconium corundum.

Types of Thermal Storage refractory balls

Refractory ceramic ball can be used in high and low temperature shifting furnaces, reforming furnaces, hydroconverters, desulfurization tanks, and refractory balls and heating conversion equipment that are replaced by hot blast stoves in the steel industry.

Refractory ceramic ball has high strength and wear resistance; the thermal conductivity and the heat capacity are large, and the heat storage efficiency is high; the thermal stability of the regenerative porcelain ball is good, and the temperature is not easily broken 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 ball makes the combustion temperature quickly reach the rolling steel to heat the steel slab. Requirements.

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

Use precautions of Thermal Storage refractory balls

Thermal Storage refractory balls is a class of alumina spheres that are referred to as high alumina spheres due to their high alumina content. High alumina balls can be subdivided into series of 90, 92, 95, 99, etc. according to the alumina content.

Thermal Storage refractory balls is widely used in different types of ceramics, enamel, glass, chemical industry because of its high strength, high hardness, high wear resistance, excellent specific gravity, small volume, high temperature resistance, corrosion resistance and pollution-free. And so on the factory's thick and hard materials finishing and deep processing.

Thermal Storage refractory balls, The users of high-aluminum balls are mainly ceramic factories. At present, there are data showing that grinding mud with 10% high aluminum balls (φ35MM) of pebbles (natural ball stones) can reduce the grinding time by 15% compared with pebbles only. Aluminum ball 30% high aluminum ball (φ35MM) grinds the mud, compared with only the aluminum ball, can shorten the grinding time by about 30%, simply calculate the electricity cost saved, about 2 years can be used because of the use of high aluminum balls The higher cost "province" comes back.

Thermal Storage refractory balls ,According to reports from individual manufacturers, all the natural ball stones were replaced by high-aluminum balls, and the output was about three times. Grinding raw materials with high-aluminum balls not only saves electricity costs, increases production, but also improves the efficiency of mechanical use, and has a great protective effect on mechanical equipment.

Thermal Storage refractory balls ,At present, the main problem encountered in the use of high-aluminum balls is that high-aluminum balls have high hardness and brittleness. Dry grinding is likely to cause cracking of the ball stones and pits on the surface of the ball stones, resulting in a very high wear rate. The method of polishing the ball stone before, picking out cracked or high-strength ball stones to minimize the loss of customers.
