Tar Dolomite Refractory Bricks
Tar dolomite refractory brick products are various shaped refractory brick products made from high-quality sintered dolomite as raw material and adding tar or asphalt as binding agent. Tar Dolomite Refractory Bricks (1) Characteristics of raw materials. Sintered dolomite is the main raw material for tar dolomite refractory brick products, and its chemical composition, sintering degree and freshness must be qualified. Tar and asphalt act as binding agents in tar dolomite refractory brick products. It is distributed between the sintered dolomite particles and partially penetrates into the interior of the dolomite. During the heating process, fine volatiles are softened, leaving fixed carbon, which is further graphitized to form a carbon network skeleton. Thereby enhancing and improving the high-temperature structural strength (load softening temperature), slag resistance and hydration resistance of the product. At the same time, the carbon mesh skeleton improves the thermal conductivity...
