High Strength High Aluminum Castable Introduction
High strength high alumina castable is synthesized by a high ratio of high alumina aggregate, powder and binder and admixture. It has high temperature performance, high tolerance, wide temperature, no reduction, and wear resistance. In depth application in hardware, smelting, chemical, non ferrous metals and other industries, especially in the steel industry, important applications in the front kiln mouth of the rotary kiln, disintegration furnace, kiln hood and other parts.
High Strength High Aluminum Castable Feature
High strength high alumina castables are resistant to penetration, erosion, impact, abrasion and mechanical properties.
High temperature performance, high tolerance, wide temperature, no reduction, wear resistance.
High strength high alumina castable as the least wear loss, high strength, arbitrary shape control, strong integrity, simple construction and good construction performance. Due to the addition of high molecular polymer, the base concrete is firmly bonded.
