Product Description of Factory Wholesale Price High Alumina Refractory Brick RS-55 RS-65 RS-75 Alumina Brick For Steel And Glass Furnace

High alumina brick is an alumina-silicate refractory material containing over 48% alumina oxide. It is produced through the calcination and molding of bauxite or materials with a high AL2O3 content. It exhibits excellent thermal stability with a refractoriness exceeding 1770℃. Additionally, it offers strong resistance to slag, making it ideal for lining steel-making electric furnaces, glass furnaces, and cement kilns.

Features And Application of RS-55 RS-65 RS-75 Alumina Brick For Steel And Glass Furnace

High Alumina bricks possess outstanding characteristics such as exceptional high-temperature resistance, impressive resistance to corrosion and abrasion, elevated bulk density, and minimal iron content. They find extensive applications in mining, metallurgy, cement, chemical, refinery, and refractory industries. These High Alumina bricks, containing 70% Al₂O₃, are suitable for a wide range of uses including electric arc furnace roofs, steel ladles, cement rotary kilns and their coolers, lime kilns, aluminum melting furnaces, kilns for the chemical industry, reheating furnaces and soaking pits, and glass tank furnaces among others.
