Box type annealing furnace, method for annealing of thin sheet metal using the same, and thin sheet metal recozida

摘要

Invention patent: b "box type annealing furnace, method for annealing of thin sheet metal using the same, and thin sheet metal recozida" d .A box type annealing furnace for recozer a thin sheet metal includes a unit for removal of oxygen to remove oxygen in the atmosphere in an annealing furnace box type.With a system of movement of gas to remove the atmosphere of the annealing furnace box type during annealing, treat the gas.And to feed the gas desoxidado to box type annealing furnace. The box type annealing furnace may also include a removal unit to remove moisture from the gas unit.The unit of removing oxygen and moisture removal unit can reliably remove oxygen and moisture from the gas and suppress the formation during the annealing.Of oxide film on the thin sheet of ferrous metal.
