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 as much continuity, temperature is generally 200 ℃ -350 ℃, furnace equipment classification, installed power 150kw-300kw. Roaster kiln mostly intermittent jobs, mostly in the use of temperature 400 ℃ -700 ℃, 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 fired in the kiln, the removal of volatile, furnace equipment, thus producing asphalt fumes, the workplace and the surrounding environment pollution. Crystalline structure of limestone calcination speed, the ash quality have a greater impact. Such as soft rock, marbled thin limestone, limestone calcite (CaCO3) crystal small size, there is a gap between the grains, at low temperature calcination volume expansion and less brittle, easily separated at high temperature CO2 escape, furnace plant, the more burning limestone, industrial furnace equipment, fine lime particles generated good activity; slope stone, rough marbled limestone contrary. When the temperature at 500 ~ 600 ℃, CaCO3 decomposition point has not been reached, because the limestone calcite crystal size of coarse, dense structure, due to the volume expansion cracked heat after they pass easily into pieces, fine, kiln will block the wind road, firing conditions worsen, the decomposition of CO2 escaping resistance, decomposition is slow, should not be used.
