Galvanizing is the process of surface treatment of steel wire by soaking it in a zinc-coated solution. This treatment can form a zinc layer on the surface of the steel wire, making the steel wire more resistant to corrosion and wear. However, when galvanized steel wire is wire-drawn, some problems arise, one of which is the change in breaking strength.
Wire drawing involves passing steel wire through a series of drawing processes to obtain different radial dimensions. During this process, the steel wire will be stretched and bent to a certain extent, which affects its breaking strength. Therefore, when performing wire drawing processing, we need to consider the change in breaking strength of the steel wire in order to provide valuable information for subsequent use.
So, what will happen to the breaking strength of the steel wire after galvanizing is replaced by wire drawing? We can consider this issue from the following factors.
The thickness of galvanizing is one of the important factors affecting the breaking strength of steel wire. Generally speaking, the thicker the galvanizing, the higher the strength of the steel wire will be, because galvanizing can reduce the deformation rate and strain hardening of the steel wire, thereby increasing the strength of the steel wire. However, during wire drawing, if the thickness of galvanizing is too thick, there will be too much zinc layer on the surface of the steel wire, which will limit the tensile and bending capabilities of the steel wire and affect the breaking strength of the steel wire.
The parameters of the wire drawing process are also an important factor affecting the breaking strength of the steel wire. During the wire drawing process, the steel wire will be stretched and bent to different degrees, thus affecting its breaking strength. Common drawing parameters include: drawing speed, number of drawings, drawing temperature, etc. Reasonable selection of these parameters can maintain the breaking strength of the steel wire at a certain level and improve the plastic deformation ability of the steel wire.
The material of the steel wire is also an important factor affecting the breaking strength of the steel wire. Different steel materials have different chemical compositions and mechanical properties, which will have different effects on the breaking strength of steel wires. Therefore, before performing wire drawing treatment, it is necessary to understand the specific material of the steel wire and select appropriate wire drawing parameters accordingly to achieve the best results.
