Galvanizing is the process of surfacing steel wire by soaking it in a solution coated with zinc. This treatment can form a layer of zinc on the surface of the steel wire, so that the steel wire is more resistant to corrosion and wear. However, when the galvanized steel wire is drawn, there will be some problems, one of which is the problem of changing the breaking strength.
Wire drawing is the process by which the wire is drawn through a series of drawing processes to obtain different radial dimensions. In this process, the steel wire will be stretched and bent to a certain extent, which will affect its breaking strength. Therefore, when performing wire drawing treatment, we need to consider the change in the breaking strength of the steel wire in order to provide valuable information for subsequent use.
So, how will the breaking strength of the steel wire change after the galvanized wire drawing? We can consider this problem from the following factors.
Thickness of galvanizing
The thickness of galvanized steel wire is one of the important factors affecting the fracture strength of steel wire. In general, the thicker the galvanized, the higher the strength of the steel wire, because galvanized 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 galvanized is too thick, it will lead to too much zinc layer on the surface of the wire, which will limit the tensile and bending ability of the wire and affect the fracture strength of the wire.
Parameters of the wire drawing process
The parameters of wire drawing process are also an important factor affecting the fracture strength of steel wire. In the process of wire drawing, the steel wire will be subjected to different stretching and bending degrees, which will affect its breaking strength. Common drawing parameters include: drawing speed, drawing times, drawing temperature, etc. Reasonable selection of these parameters can keep the fracture strength of the steel wire at a certain level and improve the plastic deformation ability of the steel wire.
Steel wire material
Steel wire material is also an important factor affecting the fracture strength of steel wire. Different steel has different chemical composition and mechanical properties, which will have different effects on the fracture strength of steel wire. Therefore, before the wire drawing process, it is necessary to understand the specific material of the steel wire, and select the appropriate wire drawing parameters accordingly to achieve good results.
