the refractory ball is made of industrial alumina and refractory Kaolin as the main raw material by scientific formula, forming and high temperature calcination.
Characters of Refractory ball:

1. High mechanical strength and long cycle of use.

2. Good Chemical stability, no Material chemical reaction;

3. High temperature performance, refractory ceramic ball maximum heat temperature can reach 1900 degrees.

Application of Refractory ball:

It is especially suitable for the high and low temperature conversion furnace, conversion furnace, hydrogenation converter, desulfurization tank and methanation furnace of chemical fertilizer plant to dispersed gas and liquid,and support, cover and protect the catalyst. Refractory ceramic balls can also be used in the hot and cold stoves and heating transformers of the steel industry.

 Refractory ceramic ball include ordinary refractory ball and high alumina refractory ball. Ordinary refractory ball is mainly for converter and converter furnace of sulfuric acid and fertilizer industry, high alumina refractory ball for  hot stove, heating furnace and other equipment of urea, steel and other industries.
