Production process of high Anti-stripping alumina brick

High Anti-stripping alumina bricks are high-alumina bricks with anti-stripping properties produced by adding ZrO2 (zirconium dioxide) or other materials based on high-alumina clinker. The production process of anti-stripping high-alumina bricks is relatively complex, and the production is roughly divided into four stages: preparing the required raw materials—extrusion molding—high temperature forging—cooling and packaging.
