  • High Alumina Plastic Refractory

This product is made of high-quality bauxite as the main raw material and phosphate as the binder. It has the characteristics of long shelf life, good thermal shock resistance, and good construction performance.

  • Light Weight Insulating Castable

The castable is made of mullite lightweight aggregate, floating beads as main raw materials, and aluminate cement is used as the binder. It has the characteristics of good thermal conductivity, high strength and so on. It is widely used for heat insulation of kilns.

Refractory Bricks of Aluminum Electrolysis Cell :

Bricks for Aluminum Electrolysis Cell(side wall bricks, corner bricks and composite bricks)
Not only made of high-quality silicon carbide and industrial silicon powder as raw materials, but also made by vibrating pressure forming and stepped high pressure oxidation process, this product is characterized with good cryolite corrosion resistance, strong oxidation resistance, high temperature strength, strong thermal conductivity and long service life , so it is an ideal material for the side wall of a 180KVA large-scale pre-baked electrolytic cell. Compared with carbon blocks, this product improves current efficiency, reduces DC power consumption, and has a significant effect of energy saving and consumption reduction.

Silicon Nitride Bonded Silicon Carbide Port Bricks :

This brick has the characteristics of high temperature resistance, corrosion and erosion resistance of molten aluminum (aluminum alloy), no pollution of molten aluminum (aluminum alloy), and good thermal shock resistance. It is mainly used in the casting process of aluminum (aluminum alloy) melting and refining.

Refractories for Copper, Zinc, Lead and Nickel industries

Direct-bonded magnesia chrome bricks are made of high-purity or sub-high-purity sintered or fused magnesia and chromium concentrate as raw materials. The product has few impurities. After being fired at high or ultra-high temperature, the glass phase is concentrated in the triangular area of the crystal phase, and the crystal phase and the crystal phase are directly combined. It has the characteristics of low porosity, high crushing strength, strong wear resistance, corrosion resistance, thermal shock resistance and good peeling resistance.

Fused Rebonded Magnesia Chrome Brick、Magnesium-aluminum-chromium Composite Spinel Brick

Fused rebonded magnesia chrome bricks are re-sintered products made of fused magnesia chrome particles.

Magnesium-aluminum-chromium composite spinel brick is a new type of high-grade composite material, which developed by Rongsheng according to the characteristics of zinc volatilization kiln. It not only has excellent scouring and erosion resistance, but also has good peeling resistance. After being used by Zhuzhou Smelting Co., Ltd., Yunnan Copper Zinc Co., Ltd. and other large zinc smelting enterprises, this kind of brick has obvious advantages over chrome slag bricks, direct-bonded magnesia chrome bricks, magnesia bricks and thermal shock resistant high alumina bricks. It is the ideal material for zinc volatilization kilns.
