Brief Introduction Of High Alumina Ball
The aluminum content of 60%-65% is classified as medium aluminum balls, the aluminum content of 75%-80% is classified as medium-high aluminum balls, and the aluminum content of more than 90% is classified as high aluminum balls. Among them, high aluminum balls are further divided into 90 porcelain, 92 porcelain, 95 porcelain and 99 porcelain.

Application
High alumina 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.
