热处理用的各种电炉(电阻辐射炉和内热式电极盐炉)主要热源是电力。在使用过程中,电能所产生的热量,有很大一部分由于热的传导和辐射的作用而散失掉了,白白地耗费了电力。设备越大,电力也浪费越多。要节约热处理用电,主要要减少这种热量的损失,同时要使设备和辅助工具的体积适合产品的要求,不宜过大。我厂热 Various heat treatment furnace (resistance radiation furnace and internal thermal salt furnace) is the main source of heat. During use, a large part of the heat generated by electric energy is lost due to the conduction and radiation of the heat, and electricity is consumed in vain. The larger the equipment, the more power is wasted. To save the heat treatment of electricity, mainly to reduce the loss of this heat, while making the size of equipment and auxiliary tools suitable for product requirements, should not be too large.
