Energy performance of refractory fibers

Cupola furnace is the major melting equipment in foundry production at home and abroad Melting industry component accounted for about 70% of the energy consumption of total energy production of castings. In the cupola melting process, using micro-computer control and manually control compared to the amount of coke can save 10% -15%, and to get pure molten and a suitable hot metal temperature Microcomputer control products in more than casting manufacturers use to achieve significant energy savings. Cupola dedicated high pressure centrifugal blower, compared with a Roots blower, can save 50% -60%. Currently, the thermal efficiency of cupola is generally 24% -34%.
 Energy of Yilong electric furnace in casting second only to melting furnace is about 20% of total energy consumption. Transforming the various furnace, drying furnace, annealing furnace, using technology from the furnace structure to burn, as well as new crafts, new technology, continuous innovation.
 Refractory fiber is the new energy-saving materials prevented in the last decade. Using fire-resistant fiber, the transformation of existing industrial furnace is simple, less investment, energy-saving effect is remarkable. Refractory fiber with resistance to high temperature, low thermal conductivity, low thermal capacity, good thermal insulation properties and chemical stability and a series of excellent performance. Using it can reduce heat loss and heat storage losses lining, saving 20% -40%. In addition coaling to coal-fired industrial furnace, oil-cooled electric drum with mechanical coaling coal compared with manual processing, coaling regular, uniform, reducing gas, solid incomplete combustion heat loss, can saving 20%. Drying furnace and other heating furnace using far infrared drying technology, drying speed, good drying quality, and it can save about 30% -40%.
