Alumina Refractory Ball

Alumina Refractory Ball

The main materials of refractory ball are industrial alumina and fire-proof kaolin, it is made by scientific formula, molding and high temperature calcination. Its maximum refractoriness can reach 1900. It is of high mechanical strength, long service life, good chemical stability, high temperature resistance, etc.

Refractory balls include ordinary refractory ball and high alumina refractory ball. The ordinary refractory ball is suitable for converter and shift converter of sulfuric acid and fertilizer industry. High alumina refractory ball is suitable for the hot-blast furnace, heating shift converter and other equipment of urea and steel industry.
