In according to the different type of blast furnace design requirements and different materials, carbon ramming material secondary carbon brick for blast furnace bottom and furnace bottom sealing plates and carbon brick hearth and the gaps between the cooling stave, and furnace bottom water pipeline above leveling and cooling wall, filling all parts requirement after ramming material carbon ramming material has a certain strength and density, filled with every corner and small aperture, reach the molten iron and the requirement of gas leakage, and the coefficient of thermal conductivity of carbon ramming material with hot blast furnace carbon brick and the function of the cooling stave to fundamental differences, not only affecting the service life of blast furnace, and adhere to the normal consumption of blast furnace. However, in the application of carbon ramming material, the common problem is that the thermal conductivity of ordinary carbon ramming material is low, which is not conducive to the rapid cooling of the blast furnace body, thus affecting the service life

Therefore, the renewal, research and use of carbon ramming materials with high thermal coefficient have market prospects. Whether the additive is added in the carbon ramming material, after onset of in situ reaction in low temperature change information function, or change some data using constructed from the design Angle, can make carbon ramming material layer to work at lower temperature, arrived with the coefficient of thermal conductivity of carbon bricks and cooling stave are mating, to ensure that the heat transfer of usually, no damage to all its construction structure, so as to reach the requirement of the blast furnace life progress.
