1, continuous production, short cycle, yield, high quality. 2, countercurrent principle work, therefore, high thermal efficiency, fuel economy, because the use of heat retention and heat very well, oriental green lime kiln, so it saves fuel. 3, the firing time is shorter, the more common large kiln from the kiln fitted to the air takes 3-5 days, and tunnel kiln, there was about 20 hours to complete. A. 4, to save labor. Light a fire only when the operation is simple, but loaded kiln and kiln operations are carried out in the kiln, it is also very convenient, to improve the working conditions of operators, reduce labor intensity. 5, to improve quality. Preheating zone, firing zone and cooling zone temperature of three parts, often to maintain a certain range, easy to grasp its firing rules, so the quality is also good, less breakage. 6, kilns and kiln are durable. Because the kiln from thermal shock effects, so the kiln and long service life, generally 5--7 years to repair once. Electric furnace kiln electric furnace kiln applications in recent years gradually increased, Shandong environmental protection lime kiln, mostly for heat-treated MgO-C, long outlet, skateboards and other products, but also for skateboarding, long nozzle firing and silicon nitride special refractory firing. Electric furnace production recorded live, convenient and reliable temperature control and good production environment. Electric furnace kilns, furnaces for heat treatment furnaces mostly as much continuity, temperature is generally 200 ℃ -350 ℃, the installed power 150kw-300kw. Roaster kiln mostly intermittent jobs, mostly in the use of temperature 400 ℃ -700 ℃, environmental protection lime kiln, with product varieties and installed power requirements of the heating rate, the difference is large, more than 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 cities, 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.
