Sillimanite brick, andalusite brick is in high alumina brick ingredients to add a certain proportion of sillimanite or andalusite and other trace elements made of products, also known as three stone products.

Sillimanite brick, andalusite brick is in high alumina brick ingredients to add a certain proportion of sillimanite or andalusite and other trace elements made of products, also known as three stone products. This series of products has excellent thermal shock resistance, and high temperature creep has also been greatly improved. In the blast furnace, hot blast stove, torpedo tank and other key parts of the use received good results.
