Embodiment Construction
[0015] As shown in the figure, the device of the present invention includes a pay-off device 1 and a take-up device 2, two electrode holders 3 are arranged between the pay-off device and the take-up device, and the two electrode holders can be placed on a linear guide rail 5 Move it up to change its spacing. A plurality of metal wheels 4 are respectively arranged on the two electrode seats as electrodes, and the two groups of electrodes are respectively connected to the two poles of the power supply. Insulation between seats.
[0016] When the device of the present invention is annealing the metal wire, the metal wire 6 released by the pay-off device 1 bypasses the outer edges of each metal wheel 4 in the two groups of electrodes successively, and is then wound up by the wire take-up device. 1. Turn on the power supply during the unwinding process, so that the metal wire between the two sets of electrodes is energized to heat up to the annealing temperature. When the metal wi...

The invention belongs to a technology for metal heat treatment and relates to a metal wire directly-heated annealing method for carrying out annealing to steel wire, stainless steel wire and other metal materials and a device thereof. The method comprises the following steps: a wire releasing device which can release the metal wire and a wire furling device which can be matched with the wire releasing device and can furl the metal wire are arranged; two sets of electrodes are arranged between the wire releasing device and the wire furling device at certain alternate distance in order that the metal wire released by the wire releasing device is sequentially contacted with the two sets of the electrodes, enters the wire furling device and is furled; in the continuous moving process of the metal wire between the wire releasing device and the wire furling device, certain voltage is applied to the two sets of the electrodes in order that current passes through the metal wire positioned between the two sets of the electrodes and heats the metal wire to reach the annealing temperature; and when the metal wire is shifted out from the middle between the two sets of the electrodes, the metal wire is cooled to complete the annealing process. The method and the device have low equipment input, high energy utilization rate, and can continuously operate, handling capacity is not limited and the method and the device have high treatment efficiency.
Description
technical field [0001] The invention belongs to metal heat treatment technology, and relates to a metal wire direct heating annealing method and device for annealing metal materials such as steel wire and stainless steel wire. Background technique [0002] In the prior art, metal materials are usually annealed by feeding the material into an annealing furnace to be heated to a required annealing temperature, and then cooling to complete the annealing process. This method needs to set up an annealing furnace, which not only requires high equipment investment, but also has a low utilization rate of energy consumption, and the processing capacity is limited by the specifications of the annealing furnace, and the processing efficiency is also low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a metal wire direct heating annealing method and device with low equipment investment, high energy utilization rate, continu...
