According to different blast furnace types and different material design requirements, carbon ramming materials are mainly used in the gap between the carbon bricks at the bottom of the blast furnace and the sealing plate at the bottom of the furnace, between the carbon bricks in the hearth and the cooling wall, and the water-cooled tubes at the bottom of the furnace. For the leveling above the center line and the filling of the cooling wall, all parts require that the carbon ramming material after the ramming material has a certain strength and density, and fills every corner and small gap to achieve no leakage of molten iron and gas. 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 and maintain the normal production of the blast furnace.

carbonramming materialThe problem often encountered in use 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 updated research and application of carbon ramming materials with high thermal conductivity are very marketable. Prospect. Whether it is adding admixtures 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 can reach the maximum working temperature when the working temperature increases. The thermal conductivity matched with the carbon bricks and cooling staves ensures the normal heat conduction and does not damage the overall construction structure, so as to meet the requirements of improving the life of the blast furnace.
