During this operation, you may encounter many problems. For example, common problems include: the wire diameter becomes thinner after annealing, scratches on the surface, discoloration of the copper wire, and oxidation of the copper wire. Next, we will analyze the specific cause of the error based on the specific problem performance. As for this problem, we think it can be solved in this way, that is, when selecting the continuous annealing outlet die for the wire drawing machine, it should be 0.0015-0.0035 larger than the actual required wire diameter.
As for the second question, usually, it is more common when the wire drawing machine draws thick wire. This is because the contact surface of the thin line is small, so it does not seem so obvious. The thick line has a relatively large contact area, so it seems obvious that there are scratches. In this case, some friction can be reduced to a certain extent. Or, increase the tension appropriately while ensuring the same quality.
As for the third question, when performing continuous annealing, cooling is required in time. When cooling in a large format is required, it may cause insufficient cooling, which may lead to a higher temperature of the lead wire, which may cause the discoloration of the wire of the wire drawing machine. In response to this situation, we suggest that both water outlets should be opened at the same time, so that the cooling effect can be enhanced.
Of course, in actual operation, you may encounter many other problems, but no matter what kind of problem, we need to find out the specific reasons before we can take targeted measures, and we can’t completely solve the phenomenon and ensure the drawing.
