Brown fused alumina
Refractories are construction materials designed to withstand aggressive service conditions at high temperature. Refractory materials are used as heat-resistant walls, coatings or linings to protect units from oxidation, corrosion, erosion and heat damage. Industries that need refractories include: steel, non-ferrous metals, glass, power, cement, petrochemicals and waste incineration. Refractory products can be divided into the following types: Bricks and shaped materials, monolithic materials and insulating materials.
Bricks and shaped materials – prefabricated shapes including bricks for linings, kiln furniture and functional products such as slide gates for steel flow control.
Surface treatment operation that consists in impacting the surface with free abrasive particles from a high-pressure air or water stream.
