bright annealing furnace of stainless wire

摘要

The present invention relates to a bright annealing furnace of an austenitic stainless steel wire, and unlike the conventional bright annealing furnace, it is intended to improve productivity by forming a hollow tube in which the stainless wire is inserted and heated and cooled in multiple stages. The present invention is provided with a plurality of heating coils (15) therein for the heating furnace 10 to form the internal temperature to a high temperature; A cooler 20 spaced apart from the heating furnace 10 and formed to continuously flow in and out the cooling water; A hollow tube 30 installed in two stages in a zigzag form in the heating furnace 10 and the cooler 20 to allow heating and cooling of the stainless wire 50 to continuously move therein; The gas inlet 40 for coupling the hollow tube 30 formed in the heating furnace 10 and the cooler 20 and supplying ammonia gas; Bright annealing furnace of stainless wire.
