[0028] The outer wall of the winding roller 214 is bound and connected with a connecting rope 216, the outer wall of the connecting rope 216 passes through the through groove 213, and the outer wall of the connecting rope 216 is slidably connected to the two pulleys 221.

[0034] When the top surface of the sliding plate 210 is lifted to be level with the bottom of the processing mold, push the sliding plate 210 to make it contact with the furnace body 102, then hold the thermal insulation sleeve 219, and connect the hook 218 to the processing mold in the furnace, then rotate the rotating handle 215 to drive the winding roller 214 to rotate, and then wind the connecting rope 216 to the outside of the winding roller 214. During this period, the hook 218 pulls the processing mold out of the inside of the furnace body 102 and removes it to the top. With the support of each rotating roller 212, the processing mold can slide completely to the top of the sliding plate 210, which is convenient for the subsequent cooling of the circumferential graphite sealing ring inside the processing mold.
