辐射导热式空气预热器的应用,能使冲天炉、锻造加热炉等具有能充分利用烟气余热、工作效率高、加热质量好、操作方便以及节省耐热钢等优点。早在1965年,长春第一汽车制造厂的锻造加热炉就使用了这种预热器。嗣后,他们又把这种预热器作为炉墙的一部分,这样,在建造加热炉时,能节约耐火砖98%、钢材82%、煤气75%,单位炉底面积产量增加15～24倍,炉子热效率提高3倍。由于辐射导热式空气预热器的应用,长春第一汽车制造厂、洛阳拖拉机厂等的平锻车间已全部实现转炉化。
Radiation thermal conductivity air preheater application, can make cupola, forging furnace, etc. can take full advantage of flue gas waste heat, high efficiency, good heating quality, easy operation and the advantages of saving heat-resistant steel. As early as 1965, the first car factory in Changchun forging furnace on the use of this preheater. Subsequently, they again put the preheater as part of the furnace wall, thus saving 98% of refractory brick, 82% of steel, 75% of gas and 15-24 times of increase of floor area per unit while building the furnace, Furnace thermal efficiency increased by 3 times. Due to the application of radiant heat-conducting air preheater, the flat-forging workshop of Changchun No. 1 Automobile Factory, Luoyang Tractor Factory and others has all realized converter.
