Product Introduction
Refractory balls are made of industrial alumina and refractory kaolin as the main raw materials, which are made by scientific formula, forming and hightemperature calcination.Refractory ball is divided into ordinary refractory ball and high aluminum resistance ball.Refractory ball high temperature resistance to high temperature can reach 1900 degrees, high mechanical strength and long-term use.

Aplication:
Refractory balls are widely used in high & low temperature conversion furnaces, hydrogenation converters, desulphurization tanks and methanation furnaces to support, cover and protect the catalysts. They can also be used in heating furnace of iron and steel industry and the transformation of equipment.Ordinary refractory ball is suitable for sulfuric acid and fertilizer industries converter and transform furnace.High aluminum refractory ball is suitable for industries such as steel, urea, hot blast furnace, heating and transformation furnace and other equipment.
