Thermal Shock Resistant Silica Refractory Bricks / Mullite Brick For Cement Kiln
Corrosion resistant micro-expansion refractory brick for tank body of tank calcination furnace, this product is a new product developed by our company. Its biggest feature is high strength, good wear resistance, dense structure, the production and manufacturing technology adopted can form a continuous Sio2 dense glaze layer on the brick surface, preventing the corrosion of harmful elements in the carbon material sulfur, the product high temperature bending strength, the product's thermal shock stability is good performance characteristics, so that the product is not easy to break and spalling. The thermal conductivity of the corrosion-resistant micro-expansion refractory brick is higher than that of the existing silicon brick material, which can also speed up the transfer of heat energy in the tank, improve the heat storage rate in the tank, so that the temperature difference in the tank can be controlled in a small range, ensure the ideal combustion state, so that the petroleum coke can be quickly and fully calcined, and can save fuel.
Another feature of the product is that the coefficient of thermal expansion is small, and small expansion will be generated in use, which is conducive to improving the structural stability of the calciner tank, and the brick can be closely combined with the brick, with good volume stability, and can extend the service life of the calciner.
