1.Furnace body is composed of furnace cover, cylinder furnace, furnace chassis and chassis. the interlayer of furnace cover, cylinder furnace and furnace chassis is bubbled into water cooling water. Inside of furnace is equipped with double layer stainless steel or alloy steel heat insulation shield. Furnace body has double layer tempered glass, used for observing the nitriding processing.
2.Furnace cover has two sets cathode transmission device and a thermocouple hanging column. The lifting appliance is designed according to heat treated parts, the parts are hang by lifting applicance.
3.Vacuum pumping systems consist of two sets of rotary vane vacuum pumps and pipe system of stringing butterfly valve. By closing or rotating butterfly valve in different angles to adjust the swept volume, the function of butterfly valve is to maintain furnace inside pressure under the condition of different air inflow. Use vacuum gauge to measure vacuum degree, and also display vacuum value.
