    The density of insulation firebrick is 0.60~1.25g/cm3, and the working temperature is 900°C to 1600°C. Insulation firebrick can reduce the cost of the foundation, reduce the cross-section of the frame, and save reinforced concrete can significantly save the comprehensive cost of the building. Compared with solid clay bricks, the overall cost of using lightweight bricks can be reduced by more than 5%. Lightweight bricks have good work ability and are easy to construct.

  • Magnesia Spinel Brick

    Magnesia Spinel Brick

    Magnesia spinel bricks use high-purity magnesia and magnesia alumina spinel as the main raw materials. The firing temperature and firing atmosphere are strictly controlled to make it have good flexibility and thermal shock stability, kiln skin performance and corrosion resistance The performance exceeds that of high-quality magnesia chrome bricks.

  • Magnesia Hercynite Brick

    Magnesia Hercynite Brick

    Magnesia hercynite bricks have the advantages of chromium-free environmental protection, good thermal shock stability, good kiln skin hanging ability, good corrosion resistance, low thermal expansion and low thermal conductivity, and better structural flexibility. In practical applications, the brick has a service life of more than 1 year, the kiln skin is hung quickly in the firing zone, the thickness of the kiln skin is uniform and stable, the refractory bricks have no large flaking phenomenon, and there is no flaking phenomenon of refractory bricks when the kiln is stopped. The temperature of the kiln barrel is low, and the heat energy less loss.

  • Fused Cast AZS Block

    Fused Cast AZS Block

    Fused cast AZS block manufacturing process mixes selected zircon sand and industrial alumina powder at a ratio of 1:1, plus a small amount of Na2O (added in the form of sodium carbonate), B2O3 (added in the form of boric acid or borax) flux, and mix well After being melted at 1800~1900, it can be cast to form a fused-cast brick containing 33% ZrO2. On this basis, using partially desiliconized zircon sand as raw material, fused-cast bricks containing 36% to 41% ZrO2 can be produced. Zirconium corundum bricks use industrial alumina powder and selected zircon sand as raw materials to produce refractory products with a ZrO2 content of 33% to 45%.
    Fused cast AZS block is an important refractory material to ensure the normal operation of glass melting furnaces. At present, glass melting furnaces increase the melting rate, extend the life of the furnace, and reduce fuel consumption mainly due to the use of this refractory material.

  • Al2O3-SiC-C Brick

    Al2O3-SiC-C Brick

    AI203-SiC-C brick, referred to as ASC brick. AI203-SiC-C brick is made of fused corundum (or sintered corundum, special grade bauxite clinker), graphite and silicon carbide with fixed carbon above 90%-95% as the main raw materials. It is made by adding graphite, bauxite, and additives, after batching, forming, drying and high temperature firing. ASC brick has very good high temperature performance and anti-oxidation, anti-flaking and anti-slag erosion properties, can withstand long-term high-temperature solution erosion, and has a long service life.

  • Silicon carbide brick

    Silicon carbide brick

    Silicon carbide bricks are made of silicon carbide as the main raw material, mixed with various binders according to requirements, and formed by high pressure. Silicon carbide bricks have high thermal conductivity, good wear resistance, thermal shock resistance, and corrosion resistance. They are ideal energy-saving materials for industrial kilns. It can be used for lining of aluminum electrolytic cell, molten aluminum pipe and kiln furniture for ceramic kiln, lower part of large and medium-sized blast furnace shaft, furnace waist and belly, aluminum refining furnace lining, zinc distillation tank lining, etc.

  • Alumina bubble brick

    Alumina bubble brick

    Alumina bubble brick is one of the ultra-high temperature material energy-saving insulation materials. It uses alumina hollow spheres as the main raw material and combines with other binders to fire alumina hollow spheres in a high temperature furnace at 1750. Alumina bubble brick has the characteristics of low thermal conductivity, good heat preservation, high compressive strength, and can work at temperatures below 1800°C. It has excellent heat resistance and heat insulation properties, and excellent energy saving.

  • Ladle Shroud

    Ladle Shroud

    Ladle shroud also known as the protective sleeve, is mainly used between the ladle and the tundish. It is an important part of the connection between the ladle and the tundish. The lower part of the upper connecting ladle is connected with the water outlet of the sliding nozzle device, and the lower end extends into the tundish. It prevents the molten steel entering the tundish from the ladle from being re-oxidized and splashed; protects the molten steel from secondary oxidation during casting, improves the quality of the molten steel; reduces the deposition of oxide products in the steel on the inner wall of the nozzle, and extends the service life.

  • Tundish Stopper

    Tundish Stopper

    Tundish stopper is a refractory rod that is installed in the steel bucket to control the opening and closing of the nozzle and the flow of molten steel by lifting displacement, also known as pottery stopper. It is composed of rod core, sleeve brick and plug brick. The rod core is usually made of plain carbon steel round steel with a diameter of 30-60mm. The upper end is connected with the cross arm of the lifting mechanism by bolts, the lower end is connected with the plug brick by threads or pins, and the middle sleeve brick.Tundish stopper must be carefully built and used after baking and drying for more than 48 hours to avoid breakout accidents caused by refractory explosions.

    The integral stopper rod is installed in the tundish when in use. The flow rate of molten steel entering the mold can be adjusted by controlling the position of the stopper rod head to the tundish nozzle, and argon can also be blown to the tundish through the argon blowing hole to prevent the nozzle from being blocked.
