How to maintain the protective gas purity is the key problem of stainless steel coils in the furnace. At this point, the stainless steel has good sealing property, and does not occur as stainless steel coils material of electric heating furnace for the protection of the atmosphere, provides a pure environment space. In addition, vertical furnace strip out the lower entrance are located in the furnace, the furnace pressure stable, so compared with a horizontal furnace, dangerous air into the much smaller. But the bright annealing furnace sealed box, with steel import and export delivery, tension roller and top guide roller box should ensure that a few Stainless steel coils manufacturers per million (ppM) sealing requirements, so that the oxygen, water vapor can not enter, protective gas cannot escape.

In the long term under the condition of high temperature will creep elongation. Structure of the muffle hanging on the top of the furnace, hanging, with water seal, the lower cover is not fixed, allowing some creep. Creep accumulated to a certain amount, remove the seal, using special plasma cutting machine to muffle along the cut to a. Cut a half year. The cutting operation requirements are stainless steel plate high. Full attention must be paid to the special equipment, operating space and structure, operation reliability.
