• 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.

  • Magnesia Chrome Brick

    Magnesia Chrome Brick

    Magnesia chrome brick is made of high-grade magnesite clinker and chromium oxide as raw materials, through high-pressure molding and high-temperature firing, the maximum allowable ambient temperature is 1700°C. Magnesia chrome brick has good heat peeling resistance, high alkali corrosion resistance and high thermal shock resistance characteristics, and it is environmentally friendly and has a long service life.

  • Magnesia Carbon Brick

    Magnesia Carbon Brick

    Magnesia carbon bricks are made of high melting point alkaline oxide magnesium oxide (melting point 2800°C) and high melting point carbon materials that are difficult to be infiltrated by slag as raw materials, and various non-oxide additives are added. A non-burning composite refractory material combined with a carbon binder.
    The main raw material for the production of magnesia carbon bricks, the quality of magnesia has an extremely important influence on the performance of magnesia carbon bricks. The purity of magnesia has a significant impact on the slag resistance of magnesia carbon bricks. The higher the magnesium oxide content, the lower the relative impurities, the lower the degree of silicate phase separation, the higher the degree of direct bonding of periclase, and the higher resistance to slag penetration and slag melting loss. The impurities in magnesia mainly include calcium oxide, silicon dioxide, and iron oxide. If the content of impurities is high, especially boron oxide compounds, it will adversely affect the refractoriness and high temperature performance of magnesia.

  • Magnesia Dolomite Brick

    Magnesia Dolomite Brick

    Magnesia dolomite bricks are made of high-purity and dense magnesia and sintered magnesia dolomite sand or dolomite sand as raw materials. According to different use environments, select the appropriate ratio of MgO and CaO, use anhydrous binder, and form at a suitable temperature. , High temperature firing.

    Magnesia dolomite bricks have strong resistance to low iron and low alkalinity refining slag outside the furnace, and are beneficial to desulfurization and dephosphorization to remove impurities in steel, and have the effect of purifying molten steel. Used in cement kilns, magnesia dolomite bricks have a great affinity with cement clinker, are easy to hang on the kiln, and have uniform thickness.

  • Magnesia Brick

    Magnesia Brick

    The magnesium oxide content of magnesia brick is 90%-98%. Magnesia brick has good fire resistance and corrosion resistance. It uses magnesium oxide or fused magnesia as raw materials and is fired at a high temperature of 15501600°C. It is the firing of high purity products. The temperature is above 1750℃. They are corrosion resistant and are widely used in various high temperature furnaces.
