Chrome Corundum Brick
Chromium corundum products exhibit superior high-temperature performance compared to pure corundum products.
Application
Suitable for glass melting furnaces, steelmaking metallurgical furnaces, copper smelting furnaces, aluminum electrolysis cells, rotary kilns, and high-temperature reactors.
Description
Chrome corundum bricks are produced using chromium oxide and aluminum-containing components as raw materials. These are mixed in specific proportions and melted at temperatures exceeding 2000°C to form chrome corundum clinker, with aluminum-chromium solid solution as the primary crystalline phase. The clinker is then crushed, batched, mechanically pressed, and fired at high temperature to obtain the final brick products.
