Description for Sillimanite Bricks

Sillimanite Bricks are manufactured with main raw material of sillimanite. Sillimanite is a kind of quality refractory raw materials and is used to produce high-alumina brick with low creep, high refractoriness under load, high heat shock and micro-expansive, and furnace top. Sillimanite can be transformed into mullite and free silicon dioxide through high temperature firing. Generally adopt high temperature firing method and slurry casting to manufacture. Its physical and chemical property is better than high alumina bricks. Its refractoriness is 1770~1830 ℃ and apparent initial softening temperature is 1500~1650℃. Sillimanite brick is mainly used for molding of throat in glass furnace, furnace lining and furnace throat of blast furnace, and kiln furniture in ceramic industry.

Sillimanite brick is pre-fired in the high temperature for achieving excellent volume stability in the process. Sillimanite Bricks exhibit surprisingly low porosity and excellent thermal shock resistance.

Sillimanite Bricks Properties

  • Good thermal shock resistance

Sillimanite Bricks Application

  1. Application In Non-Ferrous Metal Metallurgy Industry
    Use Sillimanite Brick as the high-temperature indirect heating material with its features of high temperature resistance, high strength, good thermal conductivity and shock resistance, such as vertical retort furnace, tray of rectifying furnace, aluminium cell, lining of copper melting furnace, arc type board of zinc powder furnace, protecting tube and etc.
  2. Application In Iron And Steel Industry
    Use Sillimanite Brick as the lining of large-scale blast furnace for longer service life with its features of corrosion resistance, heat resistance, wear resistance and good heat conductivity.
  3. Application In Metallurgical Processing Industry
    Hardness of silicon carbide ranks only second to diamond. Use Sillimanite Brick as the ideal material for wearproof tubes, impeller, pump chamber, hydrocyclones and ore bucket lining with its feature of stronger wear resistance. Its wear-resisting property is cast iron. Its service life is rubber’s 5~20 times. It is also one of the ideal materials for Airlines flight.
  4. Application In Building Materials, Ceramics And Grinding Wheel Industry
    Use Sillimanite Brick to produce kiln furniture thin plate, which not only reduce the capacity of kiln furniture but also improve the capacity and product quality of kiln and shorten the production cycle. Sillimanite Bricks are the ideal indirect materials for baking ceramic glaze.
  5. Application In Energy Saving
    Use Sillimanite Brick as the heat exchanger with its features of good thermal conductivity and stability, which reduce 20% burnup, save 35% fuel and increase 20~30% productivity.
