电加热器 （Electric heater）
加热器分为资管式和筐式加热器两种。资管式加热器设在炉膛顶部和网带下部，靠电阻丝热辐射加热制品，该型式适用于小型的退火炉。筐式加热器设在炉体的两侧，每个加热区设有炉胆，炉顶部安装有热风循环风机，循环风机将两侧加热器产生的面温在炉膛强制循环，使炉膛的温度分布均匀，该加热方式适用中大型退火炉。
制造过程和所使用的材料保证了几乎无限的使用寿命且免维护。
Electric heater
Electric Heaters are divided into porcelain tube type and basket type heaters.The porcelain tube heater is located at the top ofthe lehr chamber and the lowe!part of the bel and is heated by resistance wire thermal radiation.This type is suitoble for smal annealing lehrs. Basket heaters are located on both sides ofthelehrA hot air circulation fan is equippedon the top ofthe lehrwhich is used to circulate the suriace hot air generated by the heater on both sides in the lehr so thatthe temperature ofthe furnace is uniform.This heating method is suitable for medium and large annealing lehrs.Manufacturing processes and materials used guarantee almost unlimited lifespan and maintenance-free
