Use the action of ramming material

Everyone knows that ramming materials are widely used in metallurgy, building materials, non-ferrous metal smelting, chemical industry, machinery and other manufacturing industries. Today, I will talk about the application of ramming materials. If you are interested, you can follow the editor briefly. Learn about.

According to different blast furnace types and different material design requirements, carbon ramming materials are mainly used for the gap between the carbon bricks at the bottom of the blast furnace and the bottom sealing plate, between the carbon bricks in the hearth and the cooling wall, and for water cooling at the bottom of the furnace. The leveling above the pipeline and the filling of the cooling wall, all parts require the carbon ramming material after the ramming material to have a certain strength and density, filling every corner and small gap, and reaching the leakage of molten iron and gas. Requirements, and the thermal conductivity of the carbon ramming material and the performance of the blast furnace hot carbon bricks and cooling stave must be fundamentally different, 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 application of carbon ramming materials at present is that the thermal conductivity of ordinary carbon ramming materials is low, which is not conducive to the rapid cooling of the blast furnace body, thus affecting the service life. Therefore, carbon ramming materials with high thermal coefficient The updated research and application have market prospects. Whether it is adding admixtures to carbon ramming materials, changing the properties of materials by in-situ reaction at high temperature, or changing the application structure of some materials from a design point of view, carbon ramming can be made. When the working temperature of the material layer increases, it reaches the thermal conductivity matching the carbon brick and the cooling wall, so as to ensure the normality of heat conduction and not damage the overall construction structure, so as to achieve the requirement of improving the life of the blast furnace.
