一种采用新型保温材料和新型结构管状加热器、通过改变电热元件接法实现功率可变的新型节能电热式盐浴炉在山东莱州农机配件厂试制成功并通过了省级鉴定。该炉适用于600℃以下的回火、等温淬火、分级淬火等热处理,炉温可根据需要自动变换,炉膛各部位温差仅3～5℃。该炉比常用外热式盐浴炉节电45%以上,坩埚寿
A new type of thermal insulation material and a new tubular heater structure, by changing the heating element connected to achieve variable power of the new energy-saving electric heating salt bath furnace in Shandong Laizhou Agricultural Machinery Parts Factory trial success and passed the provincial appraisal. The furnace is suitable for tempering below 600 ℃, isothermal quenching, grading quenching and other heat treatment, furnace temperature can be automatically converted as needed, the temperature difference between the various parts of the furnace only 3 ~ 5 ℃. The furnace than the commonly used external thermal salt bath energy saving 45%, crucible life
