What should be paid attention to when loading and unloading tube furnace?

The loading and unloading of the tubular electric furnace must first open and take out the sealed end cover at one end of the furnace tube, put the crucible with the material to be loaded into the furnace tube, and then install the sealed end cover on the furnace tube flange and tighten the clamp bolts. Then set the heating curve of the tubular electric furnace and pass some atmosphere protection. Using the GWL tubular electric furnace has a good vacuum effect and avoids oxidation. After the sintering process of the product is completed, the temperature should continue to be lowered until the temperature in the furnace is lower than the process requirements. Open the sealed end cap of the furnace tube to take out the product.
