Start the cooling fan 201 and the driving motor 603. The cooling fan 201 drives the air to be discharged towards the two furnace chambers 104 and the furnace tube 105 to perform a cooling treatment on the two furnace chambers 104 and the furnace tube 105. The output end of the driving motor 603 drives the driving ring 604 to rotate.

After the furnace tube 105 is cooled, disassemble the sealing plate 702 and take out the material.
