Product Description
Refractory Alumina Ceramic Ball
Introduction
Refractory Alumina Ceramic Ball (also called High Alumina Refractory Ball, or High Alumina Sphere Refractory), Alumina ceramic ball is made of industrial alumina and refractory kaolin as the main raw materials,
The heat storage refractory ball has the characteristics of strong oxidation resistance and slag resistance.
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, hydroconverters, desulfurization tanks, and alumina balls and heating conversion equipment that are replaced by hot blast stoves in the steel industry.
Alumina ceramic ball has high strength and wear resistance; good thermal conductivity and the heat capacity are excellent, and its heat storage efficiency is high; the thermal stability of the regenerative porcelain ball is good, in high temperature room refractory ceramic ball 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 ball makes the combustion temperature quickly reach the rolling steel to heat the steel slab.
Alumina 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.
Properties
l Good chemical stability, no chemical reaction with materials.
l High mechanical strength, wear resistance, and long service life.
l Good high-temperature resistance, the highest heat resistance temperature can reach more than 1700 degrees.
l The thermal conductivity and heat capacity is large, and the heat storage efficiency is high.
l The thermal storage ceramic ball has good thermal stability and is not easy to break when the temperature changes drastically.
