High Strength 2.95g/cm3 Magnesia Spinel Brick For High Temperature Kiln
High Strength Magnesite Spinel Brick For High Temperature Kiln Various Size
Magnesite Spinel Brick
Composite spinel firebrick is a product obtained by high-pressure molding and high-temperature sintering using high-purity magnesia and magnesia-chromium composite spinel as main raw materials. Composite spinel refractory brick not only has high strength, good thermal shock resistance, but also has anti-erosion, anti-penetration and anti-reduction ability, and has good effects on high-temperature kiln such as zinc volatilization kiln.
