The effect of using ramming material

We all know that ramming materials are widely used in metallurgy, building materials, non-ferrous metal refining, chemical industry, machinery and other manufacturing industries. Today, Xiaobian will talk about the use effect of ramming materials. Ramming materials are made of silicon carbide, graphite, electric calcining, etc. Anthracite as raw material, mixed with a variety of superfine powder additives, fused cement or composite resin as a bulk material made of binder. It is used to fill the gap between the furnace body cooling equipment and the masonry or the filler for the leveling layer of the masonry. The ramming material has good chemical stability, erosion resistance, wear resistance, shedding resistance, thermal shock resistance, and is widely used in metallurgy, building materials, non-ferrous metal smelting, chemical industry, machinery and other manufacturing industries.

According to different blast furnace types and different data planning requirements, carbon ramming materials are mainly used in 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 stave, and the water cooling of the bottom of the furnace. For the leveling above the pipeline 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, fills every corner and small gap, and reaches the place where the molten iron and gas do not leak. Requirements, and the thermal conductivity of the carbon ramming material should be basically consistent with the function of the blast furnace hot carbon bricks and cooling stave, so as not to affect the life of the blast furnace, and then 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, and then affects the service life. Therefore, carbon ramming materials with a high thermal coefficient The updated research and use of carbon ramming materials have market prospects. Whether it is adding additives to carbon ramming materials, changing the function of materials through in-situ reactions at high temperatures, or changing the use structure of some materials from a planning point of view, carbon can be made. When the working temperature of the ramming material layer increases, it reaches the thermal conductivity that matches the carbon brick and the cooling wall, so as to ensure the normality of heat conduction, without damaging the overall construction structure, and then meet the requirements of improving the life of the blast furnace.
