由高频装置供电,采用石墨坩埚以感应加热方式将盐快速熔化,升温而进行工件热处理的一种新型盐浴炉——感应盐炉。比一般电极盐炉(如C—35或C—75)启动和升温速度快10—15倍,使用寿命长3～3.5倍,修炉费用便宜10～12倍;由于启动和升温速度快,节省大量的时间和电能。对于间断,小批量热处理生产收到明显的经济效果。感应盐炉在苏联已应用多年。最近,在苏联还成功地试用了由一台高频装置带两个或多个石墨坩埚的感应盐炉;同时又研试成功长形工件热处理的深井式感应盐炉,用这种感应盐炉处理的工件质量优于在电极盐炉中处理工件的质量。
Powered by high-frequency devices, a new type of salt bath furnace, induction salt furnace, is adopted, which uses graphite crucible to rapidly melt salt by induction heating and heat the workpiece. Than the average electrode salt furnace (such as C-35 or C-75) to start and heat up 10-15 times faster, the service life of 3 to 3.5 times, repair costs 10-12 times cheaper; due to start and heating speed, saving A lot of time and electricity. For intermittent, small batch heat treatment production received significant economic effect. Induction salt stove has been used in the Soviet Union for many years. Recently, the Soviet Union has also successfully piloted a high-frequency induction furnace with two or more graphite crucibles. In the meantime, it also explored deep-well induction furnaces for successful heat treatment of long workpieces. Using this induction furnace The quality of the treated part is better than the quality of the part treated in the electrode salt furnace.
