Product Description

Semi Rebonded Magnesia Chrome Brick for Copper Smelting Converter Refractory Magnesite Chrome Brick

Semi-rebonded magnesia-chrome brick is fired from partially fused magnesia-chrome sand. The main mineral composition of semi-rebonded magnesia-chrome bricks is periclase, spinel, and a small amount of silicate. The grains are opaque, the spinel in the periclase crystal is fully developed, and the matrix part is of a metasomatic turbidity structure. The inter-crystal is the direct combination of periclase-periclase or periclase-spinel, and the silicate phase exists between the crystal grains in an isolated state. The thermal shock resistance of semi-recombined magnesia-chrome brick is better than that of direct-bonded magnesia chrome brick.
This brick is widely used in roofs of open hearth furnaces, electric arc furnaces, copper smelting converters, flash furnaces, RH, DH vacuum treatment devices, outside refining VOD furnaces, AOD furnaces, cement rotary kilns, etc.
