[0002] For large welding workpieces, stress relief annealing treatment is required after welding, and then machining. The quality of the heat treatment of the workpiece plays an important role in the machining accuracy and the performance of the workpiece. The uniformity of the furnace temperature is very important in the furnace design. An important link, the uniformity of the furnace temperature directly affects the heat treatment quality of the workpiece. Due to the setting problem of the general annealing furnace during operation, the temperature control accuracy is low and the work efficiency is low. Due to the poor sealing setting, the fuel consumption is high, and the equipment is in It is easy to generate noise and harmful gas during operation, and the heat resistance effect is poor, which brings certain safety hazards to the work
