Refractory ceramic balls
Introduction:
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℃.
Application:
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.
