1 injection castable first problem to be solved is the injection castable rheological properties can be pumped, and its rheological properties determine whether it can successfully transport. The main way to solve include: ① choice of raw materials and particle size distribution: dense near round particles aggregate and reasonable particle size distribution; ② superplasticizer applications: Depending on the raw material selection, type and amount of powder with a suitable The plasticizer. Second, it must solve injection molding condensate castable moment, only their proper plastic condensate level in order to ensure the injection of the material does not flow, the rebound effect of low and pouring with similar compactness. Solution Way: different combinations for the selected systems and reduce water dispersion system, select a suitable plastic coagulant, and to determine the appropriate dosage. 2 equipment in the digestion and absorption of imported equipment, based on the completion of the equipment improvement, intensification and the like. Focus on resolving the pulse injection, guarantee ejected from the gun mouth "material note" uniform and stable. The solution is to improve the structure of the compressed air into the feed gas while adjusting the appropriate ratio. Electric furnace kiln electric furnace kiln applications in recent years gradually increased, mostly for heat-treated MgO-C, long outlet, skateboards and other products, but also for skateboarding, long nozzle firing and burning of silicon nitride and other special refractories system. Electric furnace production recorded live, convenient and reliable temperature control and good production environment. Electric furnace kilns, furnaces for heat treatment furnaces mostly continuity as much, saving kiln, temperature is generally 200 ℃ -350 ℃, the installed power 150kw-300kw. Roaster kiln mostly intermittent operation, environmental protection and energy saving kiln furnace, temperature mostly at 400 ℃ -700 ℃, the installed power with the product variety and the heating rate requirements, environmental protection and energy saving kiln 1, the difference is bigger, more in 250kw-500kw. The production of silicon nitride bonded SiC brick kiln electric furnace temperature <1400 ℃. Pollution environmental technology application and promotion of refractories plant in existence, so that Shanghai, Beijing, Guangzhou and other big cities, energy efficient lime kiln, to build in the city of refractories plant, relocation or take measures to limit discontinued. Industrial furnace refractories are key sources of pollution, in recent years, focusing on the promotion of environmental protection measures are: a) high-efficiency filter air purification dust. Smoke purification focus on the promotion of efficient bag filter, bag limits due to the required temperature of flue gas into the bag filter is less than 260 ℃ -300 ℃. After the furnace flue gas treatment through efficient dust collector, dust content can be controlled in less than 100mg / m3; b) asphalt fume treatment. Skateboards, and other products require dipping tar MgO-C, and then baked in a kiln, the removal of volatile, thus producing asphalt fumes, the workplace and the surrounding environment pollution.
