Description

technical field [0001] The invention relates to wire production equipment, in particular to annealing equipment after wire drawing. Background technique [0002] In the production process of wire rods, thicker wire rods are drawn into thinner wire rods through the wire drawing process, that is, the thicker wire rods are drawn through the wire drawing die to produce plastic deformation and become thinner wire rods, and the wire rods are processed by cold drawing In the future, there will be a hardening phenomenon, and the tensile strength and yield strength will increase significantly, which will have a great impact on the use or further processing of the wire. In order to restore the physical and mechanical properties before cold working and eliminate internal stress and defects, annealing treatment is necessary. There are many annealing methods after wire drawing. The traditional annealing method is to anneal the drawn wire separately. This method has low production effici...

AI Technical Summary

Problems solved by technology

There are many annealing methods after wire drawing. The traditional annealing method is to anneal the drawn wire separately. This method has low production efficiency and occupies a large space. Its application has gradually decreased and has been replaced by continuous on-line annealing. The DC continuous resistance annealing method is a common form of the online annealing method. It uses the principle of generating heat after the current passes through the wire to heat the wire during the running process after drawing to achieve annealing treatment. Its production efficiency is relatively high. The annealing process can be combined with the wire drawing equipment for continuous production, and the site occupation is relatively small, but the conventional annealing equipment of this type has a long annealing and cooling process, and it needs to go through a long distance for drying treatment, and the wire is easy to heat up after heating. It reacts with air to produce oxidation, the quality of the annealed wire is difficult to guarantee, and the efficiency is not high. In addition, the adaptability of the equipment is not strong, and it is not possible to provide differentiated annealing processes for different wire diameters.
