The silicon brick of hot blast furnace has the following characteristics:
(1) Under the conditions of long-term high temperature and load, the volume is stable, the high temperature creep rate is low, and one or even two blast furnaces can be used continuously.
(2) It has good thermal shock resistance above 600ºC. Adapt to the temperature variability of hot blast furnace, so that the brick and masonry remain intact.
(3) Chemical erosion resistance is better than clay bricks and general high aluminum bricks. The erosion of the silicon brick by the alkaline substances in the gas and dust is limited to the formation of a glass phase on the surface, and does not occur spalling.
(4) The thermal conductivity of silicon bricks is larger than that of clay bricks and high aluminum bricks, which is conducive to storing and releasing heat in a short time.
Company main products and profile:
Our total annual production capacity is about 100,000 tons of dense-shaped refractory product, and 100,000 tons of monolithic refractory product.
We have three tunnel kilns for silicon-aluminum dense bricks and one new plant for the monolithic refractory.
We're sure our custom-made products and professional services will bring you a stable quality supply and more profit.
