High vacuum maintenance device of annealing furnace

摘要

the design of annealing furnace of vacuum maintenance device, in particular in the annealing furnace (1) to seal the filler (2) installed on the circumference of the cooling water (41) to fill the high temperature of 600 degrees or more from the pad (2) to prevent the at the same time, it can have. (1) the perfect closed state can be maintained as a small amount of nitrogen gas annealing furnace (1) is enough to supply a good vacuum table.you can keep the product on the surface of an oxide, the occurrence of an annealing furnace, vacuum maintained in the device.
