25mm 30mm Heat Storage Refractory Ball Ceramic Fire Ball High Alumina Balls for Heat Storage
The main materials of high alumina refractory fire ball are industrial alumina and fire-proof kaolin, it is made by scientific formula, molding and high temperature calcination. Its maximum refractoriness can reach 1900ºC. It is of high mechanical strength, long service life, good chemical stability, high temperature resistance, etc.
Application:
Refractory balls include ordinary refractory balls and high alumina refractory balls. The ordinary refractory ball is suitable for the converter and shift converter of the sulfuric acid and fertilizer industry. High alumina refractory ball is suitable for the hot-blast furnace, heating shift converter, and other equipment of the urea and steel industry.
