What are the specific functions of the use of carbon ramming materials?

Carbon ramming material is a kind of ramming material. According to different blast furnace types and different material planning 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. The gap between the cooling walls, as well as the leveling above the center line of the water-cooled tube at the bottom of the furnace 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, filling every corner and A small gap can meet the requirements of no leakage of molten iron and gas, and the thermal conductivity of the carbon ramming material should be basically the same as the function of the blast furnace hot carbon brick and cooling stave, so as not to affect the life of the blast furnace, and then keep the blast furnace normal. production.

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, and then affects the service life. Therefore, the update research and development of carbon ramming materials with high thermal conductivity The application has market prospects. Whether it is adding admixtures to the carbon ramming material to change the performance of the material through in-situ reactions at high temperatures, or changing the structure of local materials from a design perspective, the carbon ramming material layer will increase in working temperature. When it reaches the thermal conductivity that matches the carbon brick and cooling wall, it can ensure the normal heat conduction without damaging its overall construction structure, and then meet the requirements of improving the life of the blast furnace.
