Metal wire preparation method

Abstract

The invention relates to the technical field of metal wires, and discloses a metal wire preparation method. The method comprises the following steps of uniformly casting molten indium on a stainless steel tube to form an indium rod; mounting the stainless steel tube containing the indium rod on a rotating device; and a grater is attached to the indium rod, the rotating device is started to drive the indium rod to rotate, and indium wire forming is achieved. By adopting the device for preparing the indium wire, the wire breakage is avoided, the length of the indium wire can be increased, the wire preparation efficiency is improved, the cross section of the grater is the same as the grater hole of the grater, the phenomenon that the outer skin is turned up is avoided, so that the condition that impurities are rolled into the core part of the wire is avoided, and the purity of the indium wire is ensured; and the method is simple to operate, good in using effect and easy to popularize and use.

Description

technical field [0001] The invention relates to the technical field of metal wires, in particular to a method for preparing ultrafine high-purity low-melting-point metal wires, and more particularly to a method for preparing indium wires. Background technique [0002] At present, most of the high-purity indium wires on the market are prepared by extrusion and wire drawing, but because indium is relatively soft and its strength is around HV4, the outer skin is prone to curling during the extrusion process, causing some impurities to enter the wire. core, thereby reducing the purity of the indium wire. At the same time, the elongation of indium is relatively poor, and it is easy to break the wire, so the general length of the wire is limited to less than 40 meters. [0003] On the other hand, the higher the purity of indium, the lower the tensile strength. For example, the tensile strength of indium with a penetration of more than 6N will be below 0.5Pa, and the traditional d...

Problems solved by technology

[0002]Currently, most of the high-purity indium wires on the market are prepared by extrusion and wire drawing, but because indium is relatively soft, its strength is around HV4. During the extrusion process, the outer skin is prone to curling, causing some impurities to enter the core of the wire, thereby reducing the purity of the indium wire

At the same time, the elongation of indium is relatively poor, and it is easy to break the wire, so the general length of the wire is limited to less than 40 meters.

[0003]On the other hand, the higher the purity of the indium, the lower the tensile strength. For example, the tensile strength of indium with a penetration of more than 6N will be below 0.5Pa, which cannot be used in traditional Preparation of indium wire by drawing method
