Description
Our Refractory for Cement Kiln refers to the high alumina bricks suitable for cement kilns, mainly including phosphate bonded high alumina bricks, phosphate bonded high alumina wear-resistant bricks and anti-stripping bricks. They have good structural stability, alkali resistance and high temperature resistance, so they are suitable for various environments. In addition, they are widely used in dry-process kilns, Libo kilns and wet-process kilns, and can be installed in kiln door covers, rising flue, cooling areas and other areas.
Features
This Refractory for Cement Kiln is a refractory material with softening temperature greater than 1500 ℃ under 0.2MPA load, and plays a vital role in the lining of rotary kiln and kiln system. It has excellent thermal shock resistance, can be cooled more than 25 times at 1100 ℃, and is not easy to deform at high temperature. In addition, its surface has good peeling resistance, which can ensure the integrity of the shape and avoid the phenomenon of surface peeling.
