• Sillimanite Brick

    Sillimanite Brick

    Sillimanite bricks are refractory bricks with good characteristics, which are prepared from sillimanite minerals by high temperature firing method or slurry casting method. Sillimanite is converted into mullite and free silica after high temperature calcination.

  • High Alumina brick

    High Alumina brick

    High alumina brick is an alumina silicate refractory material, in which alumina content exceeds 55%, and it is calcined from high content alumina raw materials. It has high heat resistance and high temperature resistance at 1770°C and above. High alumina bricks have good slag resistance and are mainly used for masonry of steel-making electric furnaces, glass furnaces, cement rotary furnaces, etc.

  • Special Alumina Brick

    Special Alumina Brick

    Special alumina bricks are made of high-grade sillimanite, pyrite, mullite, and corundum as raw materials, and have a refractoriness of 1750~1790℃. Among them, Al2O3 is high, and the amount of impurities is small, and the formation of fusible glass is small. Therefore, the load softening temperature is higher than that of clay bricks. Special alumina bricks contain more Al2O3, which is close to neutral refractory materials and can resist the erosion of acid slag and alkaline slag.

  • Corundum Brick

    Corundum Brick

    The alumina content of corundum brick is more than 90% and the main crystal phase is corundum. It has high compressive strength at room temperature (up to 340MPa), high load softening start temperature (more than 1700℃), good chemical stability, and strong resistance to acidic or alkaline slag, metal and molten glass, etc. Resistance.
    Thermal shock stability is related to its structure, and the corrosion resistance of dense products is good. There are two types of sintered corundum bricks and fused corundum bricks. Sintered alumina and fused corundum can be used as raw materials, or bauxite clinker with high Al2O3/SiO2 ratio can be combined with sintered alumina and made by sintering method. Phosphoric acid or other bonding agents can also be used to make non-fired corundum bricks.

  • Silica Brick

    Silica Brick

    Silica brick is an acidic refractory material with good resistance to acid slag erosion. The softening temperature of the silica brick under load is as high as 1640~1670°C, the volume is relatively stable at high temperature, and it can be used for a long time.

  • Clay Brick

    Clay Brick

    Clay bricks are made of 50% soft clay and 50% hard clay clinker, which are batched according to certain particle size requirements. After molding and drying, they are fired at a high temperature of 13001400. Fireclay bricks are weakly acidic refractory products, which can resist the erosion of acidic slag and acid gas, and have a slightly weaker resistance to alkaline substances, good thermal performance, and resistance to rapid cold and heat

    Clay bricks are one of the main varieties of silica-alumina series products. They are refractory products with 30-48% Al2O3 content made of clay clinker as aggregate and refractory clay as binder.

  • Andalusite Brick

    Andalusite Brick

    Andalusite bricks can save 30-50% more energy than using refractory clay or lightweight brick lining. The use of andalusite refractory bricks can not only reduce fuel consumption and increase stability, but also save more than 40% of the consumption of general refractory materials.
    Andalusite bricks can be used in key parts such as hot blast stoves and hot blast towers, as well as various auxiliary pouring and operating equipment, and can also be used to make furnace facilities, high-temperature aluminosilicate insulators, and sand moulding fabrics.
