The basic refractory brick product made of magnesia as the main raw material, magnesia and alumina (mainly bauxite) as the co-ground powder as the matrix, and fired at high temperature is called magnesia-alumina brick. It is also called periclase spinel brick. Rongsheng manufacturer‘s magnesia alumina bricks are used in the top of steelmaking open hearth furnace.
Characteristics and Uses of Magnesia-Alumina Bricks
Magnesia alumina bricks have good thermal shock stability, high-temperature mechanical strength, and high load softening temperature.
Magnesia-alumina bricks have good slag resistance, high-temperature performance, and thermal stability, and are cheaper than magnesia spinel bricks. They are widely used in steelmaking open-hearth furnace roofs. They are also used in ladles, permanent linings of steelmaking furnaces, regenerators of glass kilns, iron-mixing furnaces, copper smelting reflective kiln roofs, and high-temperature kilns in the refractory industry.
