Heat exchanger plays an important role in chemical industry, petroleum industry, power industry, food industry and many other industries. Let's discuss the role of plate heat exchanger in copper wire production.
In the production and processing of copper wire, the product after high temperature stretching molding, through the extension groove cooling cooling, but because the product after high temperature molding, the temperature is extremely high, so after cooling, the temperature of the wire drawing liquid will also rise sharply. And the use of wire drawing oil temperature and lubrication effect is mutually complementary, mutual influence, such as the temperature is too low, the new addition of wire drawing oil is not easy to emulsify, and its emulsion of particle activity will decline, not conducive to lubrication. On the contrary, the temperature is too high, the oil is easy to decompose, suspended in the emulsion, it reduces the lubrication effect. This causes the surface of the copper wire to blacken with oxidation. If the temperature of the wire drawing liquid increases further and no effective measures are taken to control the temperature, the oil film in the deformation zone may break, leading to the chemical chain fracture in the process formulation of the wire drawing liquid. In this way, the friction coefficient is bound to greatly increase, the vicious cycle, not only make the product surface oxidation black, quality decline, but also will make the temperature of the wire drawing liquid rise rapidly, resulting in a rise in the scrap rate. Therefore, it is not negligible to maintain the cooling state of the high-speed wire-drawing emulsion.
At present, some companies use cooling tower to directly cool the wire drawing liquid, which is easy to cause changes in the concentration and PH value of the wire drawing liquid, and easy to be eroded by microorganisms, resulting in the deterioration of the wire drawing liquid, thus reducing the lubrication performance of the wire drawing liquid. And the use of plate heat exchanger cooling wire-drawing oil will not appear such problems, and can also save energy, heat will be used to heat water or heat for production.
