Introduction to the role of carbon ramming material

carbonramming materialIt is a kind of ramming material. According to different blast furnace types and different material design requirements, carbon ramming material is mainly used between the carbon bricks at the bottom of the blast furnace and the bottom sealing plate and between the carbon bricks in the hearth and the cooling stave. As well as the leveling above the center line of the bottom water cooling tube and the filling of the cooling wall, all parts require that the carbon ramming material after ramming material has a certain strength and density, filling every corner and small gap. , to meet the requirements of no leakage of molten iron and gas, and the thermal conductivity of the carbon ramming material should be basically consistent with the performance of the blast furnace hot carbon bricks and cooling stave, so as not to affect the life of the blast furnace, so as to maintain the normal production of the blast furnace.

The problem often encountered in the use of carbon ramming materials is that the thermal conductivity of general carbon ramming materials is low, which is not conducive to the rapid cooling of the blast furnace body, thus affecting the service life. Therefore, the update research and development of carbon ramming materials with high thermal conductivity The application has great market prospects. Whether it is adding additives to the carbon ramming material, changing the properties of the material through in-situ reaction at high temperature, or changing the structure of the local material from the design point of view, so that the carbon ramming material layer increases in working temperature. When the temperature is high, the thermal conductivity can be matched with the carbon bricks and cooling stave to ensure the normal heat conduction without damaging the overall construction structure, so as to meet the requirements of improving the life of the blast furnace.
