Composite spinel firebrick is a product obtained by high-pressure molding and high-temperature sintering using high-purity magnesia andmagnesia-chromium composite spinel as main raw materials.
Composite spinel firebrick is a product obtained by high-pressure molding and high-temperature sintering using high-purity magnesia andmagnesia-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.
Advantage of Composite Spinel Brick
●Good thermal shock resistance
●Anti-erosion, anti-penetration and anti-reduction
● Customerize mould according to different size requirements for free
Application of Composite Spinel Brick
●High-temperature kiln
●Used for the rest part beyond the slag line of refining ladles

Al2O3-SiC-C Brick is developed with corundum, andalusite, flake graphite and SiC as the main raw materials, and bonded by phenolic resin. After being mixed, high pressure pressed, and firing treatment, Al2O3-SiC-C brick is characterized with excellent slag erosion resistance, thermal shock resistance, abrasion resistance and achieve good performance.
Zircon refractory ramming material is made of high-quality zircon sand aggregate, powder, aluminum phosphate as binder and admixture, and has the best ratio of thermal conductivity and thermal shock resistance.
Electro-fused AZS hot refractroy repair material uses fused cast corundum refractory as raw material, adding α-alumina micro-powder to the furnish, adopting new generation ceramic binder, adding special component ultrafine powder and introducing dispersing medium, modified adding phase and chemical adding phase.
