After drawing, galvanized low carbon steel wire is called galvanized iron wire, galvanized wire products such as a certain characteristics, such as corrosion resistance, in order to let the galvanized wire play effect, in the galvanizing process, generally according to customer requirements to control the thickness of the zinc galvanized wire, this allows the use of galvanized wire to meet customer demand. So, how to determine the thickness of galvanized wire?
There are three methods to detect the thickness of zinc layer of galvanized wire: weighing method, cross section microscope method and magnetic method. The first two experiments will produce certain damage to galvanized wire, including the length of galvanized wire and the reduction of the amount of galvanized wire. The general detection of galvanized wire galvanized layer with magnetic method to detect, is also a more intuitive and convenient common method.
The thickness of the galvanized layer is related to the wire diameter of the galvanized wire. The larger the diameter of the galvanized wire, the thicker the galvanized layer is. It is the thickness of the coating and the galvanized layer of cast iron after centrifugal separation.
The methods to control the thickness of zinc plating are: we can slow down the lifting rate of the workpiece. We can control the galvanizing time as much as possible. We can add a moderate amount of thinning alloy. Reduce the thickness, improve the temperature of hot dip galvanizing zinc, but to consider the situation of zinc pot, iron pot should not exceed 480 degrees, ceramic pot can be to 530 degrees, so as to reduce the zinc dipping time.
