Aluminum carbon mud is also called carbon cement. It is mainly made of high-temperature electric calcined anthracite, graphite, silicon carbide fine powder and other raw materials, composite resin and additives as cementitious materials. It is mainly used for the gap between the lining of carbon brick masonry kiln and carbon brick, as well as the filler with a width of less than 15mm due to the processing of brick. Carbonaceous mud is a kind of anhydrous carbonaceous slime with the particle size of 0.088mm-0.5mm and high viscosity, which is different from other refractory mud.
