If the surface shrinkage of wire rod is poor, what will happen to wire drawing?
If the wire rod surface quality is not good, then there will be problems after drawing, the probability is great. For example: surface defect of wire rod, out of roundness is not good, there will be reflected in the ear, drawing line.
If the surface shrinkage of the wire rod is poor, the drawing process will break, because the surface shrinkage is the shrinkage of the cross section, and is the plastic index of the wire rod. Because of the low reduction rate of drawing, it is often less likely to occur because of shrinkage during drawing.
In the process of using No. steel, it is mainly broken line, which is caused by surface quality, internal structure, mould, lubrication and so on. Specific reasons for specific analysis.
