Abstract (en)

[origin: EP0707082A1] The appts. for heat-treating steel wire after it has been rolled consists of a winding unit (WL) which forms the wire into overlapping coil shapes on a transporter bank (HF); as it moves along the band it is heat treated before being coiled (WS1). A second coiling unit (WS2) can be moved in to replace part of the band (HF). The coiled wire on this unit is then moved along the band (QF1) and fed to either a cooling water bath (5) or a coil heat treating bath (6).
