Basic structure of sealed box furnace

The front chamber of the sealed box-type furnace is not only the transition area for the incoming material, but also the output area after the workpiece is heated for quenching and slow cooling.Analysis and Countermeasures of Common Defects in Vacuum Carbonitriding To be able to quench, there should be an oil tank under the front chamber; to be able to cool slowly, the top or side of the front chamber should be connected to a slow cooling chamber. During feeding, discharging, quenching and slow cooling, the tray and the workpiece must move back and forth and up and down. The forward and backward movement is completed by a push-pull feeder, and the up and down movement is completed by a lifting mechanism.Vacuum Heat Treatment Process Of Titanium Alloy The front room can be divided into a slow cooling room and a slow cooling room. The front chamber shell is a welded square sealed chamber, which can be integrated with the furnace shell or quenching oil tank, or connected with bolts. QK1212/QK1219 CNC PIPE THREADING LATHE The front door is located in front of the front room, and is opened and closed by the motor reducer driving the chain. The asbestos rope is used between the door and the frame to be pressed by the weight of the door or the pressing mechanism. There is a fire curtain device under the door.QK1217/QK1235 CNC PIPE THREADING LATHE
