对一台炉膛容积为７０ｍ￣３，装机容量为７５０ｋＷ的强制通风大型电阻加热炉，采用远红外技术进行节能技术改造后，取得装机容量减少了６５％，年节电达百万千瓦时的显著效果，经过十余年的生产实践，证明了大型窑炉低温加热以红外辐射为主，自然对流为辅，传导起一定作用的理论是正确的。能满足热处理工件工艺要求，该炉的改造成功为大型电热窑炉节能改造提供了新途径。
For a forced ventilation large-scale resistance furnace with a furnace volume of 70m ~ 3 and an installed capacity of 750kW, after retrofitting the energy-saving technology with far-infrared technology, the installed capacity was reduced by 65% and the annual energy saving reached one million kilowatt-hours Effect, after more than ten years of production practice, proved that large-scale low-temperature furnace heating to infrared radiation-based, supplemented by natural convection, conduction theory plays a certain role is correct. To meet the heat treatment process requirements of the workpiece, the successful transformation of the furnace for large-scale electric heating furnace provides a new way to energy-saving.
