Everyone should know that for the quality and effect of wire drawing, we need to pre-treat the wire that needs to be drawn. In the process of pretreatment, it mainly includes two parts, namely surface pretreatment and heat treatment. Only the pre-processed wire can achieve a better wire drawing effect during the wire drawing process using the wire drawing machine equipment.
As for the main content of surface pretreatment, it includes: 1. If the surface of the wire contains a lot of oil or impurities, it should be cleaned and dried before drawing; 2. If the surface of the wire contains a lot of impurities If the wire surface has problems such as peeling, pits, heavy skin, etc., then it needs to be polished with a polishing machine before it is drawn. You can use wire drawing machine equipment for drawing.
After the pretreatment of the surface is completed, heat treatment is then required. If we find that the hardness of the wire is relatively large, or the hardness is not uniform, then it is often necessary to reduce the hardness of the wire through annealing or tempering, so that the wire can reach a more uniform hardness before drawing. In the heat treatment, the traditional wire drawing machine has many drawbacks.
Under normal circumstances, when heat treatment is performed, the traditional heating methods used in the past processing mainly include two kinds, namely combustion heating and electric cathode heating. In the actual heating process, these two methods have many shortcomings, such as open flames, high temperature, exhaust gas and other pollution, and the safety is not reliable enough. In addition, there are disadvantages such as high consumption, low efficiency, and uneven heating. Not only that, when drawing machine equipment, if the temperature of the wire surface is uneven, it will also affect the quality of the product.
After improvement, modern wire drawing machine equipment has made great progress in all aspects, especially in heat treatment, there has been a significant improvement. For example, after the improvement, the wire drawing machine equipment can save at least 60% of the electricity under the same conditions.
