Anhydrous press in mud (non water system press in material) is a kind of anhydrous press in mud made of high-temperature electric calcined anthracite, silicon carbide and high aluminum clinker fine powder as main raw materials, composite resin and various additives fine powder as cementitious materials, which is used to fill the gap between furnace shell and cooling wall as well as the lower part of furnace bottom sealing plate, forming a solid and compact whole after solidification, and eliminating the use of water quality in blast furnace The damage to the carbon lining caused by grouting material after the blast furnace is put into operation.
According to the different parts of the blast furnace and the use requirements, anhydrous pressed mud can produce carbon, aluminum carbon and high aluminum mud (or non water pressure feed). Anhydrous pressure mud is to determine its particle size according to the size of the filled gap. The particle size distribution system is 0.21-0.26, which has better fluidity and filling density in this range.
