The production process of galvanized wire is one-stage drawing. We pull it through the mold, which is slightly smaller than the original diameter. And so, Z will eventually stretch to the desired length. One pull is not advisable. We must have a number. The reduction from coarser to finer depends on the ductility of the metal. Too much change and we die. After Z, carefully pull to a certain diameter after galvanized, finished is finished. In this process, friction heat hardens the surface every time the wire is pulled out. So basically every time you pull it, you have to go into the stove and turn off the lights. One is to reduce the hardness of the surface, and the other is that when the wire is pulled, the surface deforms, but the center does not change. So there's a lot of internal stress. Therefore, in order to eliminate the internal stress, must rely on annealing.
The wire is softened again to remove the pressure before it becomes thin again. But we have necessary precautions in the production of galvanized wire. First, remove all tools and piles in the shop and equipment that impede activity, and place wire slowly into the jar during pickling to prevent acid spills on the body. When adding acid, pour the acid slowly into the water. Do not pour the water into the hill. In order to prevent acid spills, workers should wear protective glasses when working. Then moving wire and other items, do not push. Pay attention to safety while performing the operation, and no one else should get on the bus without permission. Shelves should be placed lightly and stacked firmly and neatly, with no more than 5 boards. Direct contact of human skin with acid and alkali is prohibited.
