在工业企业中,由于锻件和铸钢件在生产过程中,需要进行加热,大部分重要的机械零件如轴、齿轮、弹簧等,模具、量具、刀具都需要经过淬火、正火、退火、回火和渗碳、氮化等热处理工艺;以及各种材料的干燥等等,因此工业炉尤其是电炉在生产中用得十分普遍。 对电阻炉提高其能源利用率可以从两方面着手,一方面从设备上提高能源的利用率,如改造炉体;减轻装载工装;加强维护保养等, In industrial enterprises, since forgings and steel castings need to be heated in the production process, most of the important mechanical parts such as shafts, gears, springs, etc. need to be quenched, normalized, annealed, Fire and carburizing, nitriding and other heat treatment process; and a variety of materials such as drying, etc. Therefore, industrial furnaces, especially the use of electric furnaces are very common in the production. Resistance furnace to improve their energy efficiency can start from two aspects, on the one hand from the equipment to improve energy efficiency, such as the transformation of the furnace; reduce the loading tooling; to enhance maintenance and so on,
