     · Application
Model RJ2 series pit type temper electric resistance furnaces are batch type. The range of rated power is from 25to 75 kilowatts, and rated temperature is 650. The Furnaces are mainly suitable for temper of ordinary steel parts or heat treatment of other alloy parts.
 
     · Structure Features
Model RJ2 series pit type temper electric resistance furnace mainly consist of furnace shell, furnace lining, furnace cover, work basket, agitator, elevating machine and heat elements.
Furnace lining are bricked with diversified refractory material; between furnace shell and furnace lining, filled with insulating material; work basket is welded with stainless steel to load parts which will be heated.
Agitator fan could promote hot air circulating to ensure good temperature uniformity; the elevator of furnace door have two type; 25kW and 35kW are equipped with a leverage mechanism; 55kW and 75kW are equipped with a hydraulic mechanism. The heating elements of screw type which is made of high resistance alloy wire are mounted on the supporting bricks.
There are limit switch beside the lifting shaft. This unit is connected with lifting shaft. When the lifting shaft rise to make the furnace cover open, cut down the power supple of the furnace automatically to ensure the operators form danger.
There are thermocouple hole on the furnace shell, the furnace temperature can be controlled by thermocouple.
Model RJ2-xx-6(I) and model RJ2-xx-6(II) are equipped with temperature recorder and over temperature protective instrument.
