Product Introduction
RongSheng refractory ball is made of industrial alumina and kaolin as the main raw materials, through scientific formula, forming and high temperature calcination. The appearance color may be slightly yellow and the surface is relatively rough.
Refractory alumina ball is divided into ordinary refractory ball and high aluminum resistance ball. Refractory porcelain ball high temperature resistance to high temperature can reach 1900 degrees, high mechanical strength and long-term use.

Application
Refractory balls are suitable for converters and conversion furnaces in sulfuric acid and fertilizer industries, as well as hot blast furnaces and heating conversion furnaces in urea, steel and other industries. Ordinary refractory balls are suitable for general industries, while high-aluminum refractory balls are suitable for industrial environments with higher requirements.
