Product Description

Product Description

High chrome bricks are produced from high purity raw materials, such as industrial grade chromium trioxide and alumina.  The manufacturing process includes precise blending, shaping, drying, and firing at elevated temperatures to guarantee superior density and mechanical strength.
These bricks come in multiple grades, with chromium oxide content varying between 75% and 95%, allowing them to suit diverse industrial applications.  Every production batch is subject to strict quality inspections to ensure compliance with industry standards, delivering consistent performance and long-term durability.
