The invention relates to a method and device for cooling a wire for patenting processes, where the device comprises a block of material having a very high thermal capacity with a channel adapted for allowing the passage of a wire to be cooled and at least one conduit for the circulation of a cooling fluid, and it further comprises at least one nozzle capable of injecting a turbulent fluid jet towards the wire to be cooled. The turbulent jet is capable of producing cooling in the time and to the extent necessary for the patenting process, thus overcoming the need for using lead baths.

A strip material treatment apparatus (1) capable of uniforming the temperature of a strip material in the widthwise direction has a plurality of hot air blowing means (18) constituted by segmenting a circulation duct (15) having a heater (14) in the widthwise direction of the strip material (8) at the portion downstream of the heater (14) and to blow hot air against the strip material (8), temperature measuring means (20) that measures a temperature distribution in the widthwise direction of the strip material (8) in downstream of the hot air blowing means (18), and a hot air regulating means (21) that regulates the airflow quantity of hot air to be blown by adjusting the degree of opening of a damper (16) for each hot air blowing means (18) so that the temperature variation in the widthwise direction of the strip material (8) is reduced in accordance with a detection result of the temperature measuring means (20).
摘要:
The invention concerns a furnace for thermal treatment of electrically conductive strips, sheets, plates, in particular made of metal, which move in the furnace consisting of an enclosed volume maintained under a gas atmosphere, which comprises a heating section with at least one field winding formed by a pair of half-field windings with transverse and pseudo-transverse flux. In the heating section (5), at least two walls (9) of the furnace comprise each an opening (10) facing each of the two half-field windings (11a, 11b) and two panels (12) transparent to the magnetic flux cover respectively said openings (10), said panels (12) including at their periphery (14) a shape adapted to constitute a barrier to the thermal radiation of the strip without providing impermeability to the gas, and each half-field winding (11a, 11b) is accommodated in a chamber (8a, 8b) delimited by walls projecting outwards of the furnace, said chambers being tightly isolated from ambient air but communicating with the inner volume of the furnace.
摘要:
A heat treating device for a steel plate, comprising a plurality of conveying rolls for horizontally conveying the steel plate and at least one induction heating device for heating the steel plate. The induction heating devices are disposed between the specified conveying rolls adjacent to each other. At least one pressing roll for pressing the steel plate from the upper face is installed on the outlet side of at least the induction heating device located on the upstream-most side of the induction heating devices. At least the pressing roll located on the upstream-most side of the pressing rolls is disposed oppositely to the conveying roll on the upper side of the conveying roll located on the outlet side of the induction heating device. Thus, when the induction heating device is used, also a specified heat treatment can be applied to the steel plate by the heat treatment device for the steel plate without obstructing the conveying of the steel plate.
摘要:
A method for heat treatment of metal strands, especially steel strips (1), wherein a moving metal strand displaced at a speed corresponding to a set production quantity is heated in order to obtain high temperature gradients and the amount of heat required for the heat treatment of metal bands (1) can be provided in a short time period for fast-running metal strands, whereby a flux concentrator (5) is used, enabling the metal strand temperature to be controlled in the millisecond range for a fast-moving metal strand by means of inductive heating.
