Cr-Al-Zr brick

The chromium-Alumina-Zirconia bricks have very good quality with competitive price and good performance.

The chromium-Alumina-Zirconia bricksmainly applies to the inside lining of coal-water slurry gasifier, it has excellent erosion-resistance to molten coal slag, airflow and various amboceptors. High chrome brick has good thermal shock resistance stability, good high temperature strength and volume stability,  and can be used for a long time under the action of acid slag and vapour.
