  目前,在铝板生产厂家5052铝板的生产中,许多企业经常在产品表面出现残油,这可能会造成油斑和油粘。粘油的真正原因是铝箔表面不干净,可以采取以下措施减少铝板表面的残油:
  At present, in the production of 5052 aluminum plate, many enterprises often have residual oil on the product surface, which may cause oil spots and oil sticking. The real reason for sticking oil is that the surface of aluminum foil is not clean. The following measures can be taken to reduce the residual oil on the surface of aluminum plate:
  首先,在轧制过程中对油液进行清洗,如在轧辊上安装挡油板、防溅板,从轧辊颈、轧辊间隙上越过油液,并充分捕捉轧辊工作辊面上的油液。合理的上辊面、板面清洁油。可大大减少表面残油;在第二个。控制面板的形状。如果成品铝箔形状不好。切割复卷时,单面或双面缠绕紧密,导致铝盘管间隙率不均匀,各部分密封性不均匀,退火时表面残油挥发。粘稠的油可能出现在紧密缠绕的地方。

  Firstly, the oil is cleaned in the rolling process, such as installing the oil baffle and splash plate on the roll, passing the oil from the roll neck and the gap between the rolls, and fully catching the oil on the working roll surface of the roll. Reasonable cleaning oil for upper roll surface and plate surface. Can greatly reduce surface oil residue; in the second. Shape of the control panel. If the shape of the finished aluminum foil is not good. When cutting and rewinding, one side or two sides are tightly wound, resulting in uneven clearance rate of aluminum coil, uneven sealing of each part, and evaporation of residual oil on the surface during annealing. Viscous oil may be present where it is tightly wound.
  第三,选择合适的轧制速度和卷绕张力。在双辊轧制中,轧制速度过大,卷取张力过大,会降低铝箔表面的亮度,增加金属箔退火时的油气放电电阻。
  Third, choose the appropriate rolling speed and winding tension. In double roll rolling, too high rolling speed and too high coiling tension will reduce the brightness of aluminum foil surface and increase the oil gas discharge resistance during annealing.
  四是选择正确的滚压油,防止滚压油污染。铝箔轧制基础油一般采用低宽度、低闪点、精馏范围窄的油,在保证油膜厚度和强度的前提下,有利于退火炉除油。
  Fourth, choose the right rolling oil to prevent rolling oil pollution. The oil with low width, low flash point and narrow rectification range is generally used as the base oil for aluminum foil rolling.
  第五,切割时体积间隙不宜过小,并要避免翘曲,以免影响退火炉除油的效果,如果翘曲会使退火炉除油的侧阻力增大,甚至脱落。因此出现了粘着现象。
  Fifthly, the volume gap should not be too small when cutting, and warpage should be avoided to avoid affecting the effect of annealing furnace oil removal. If warpage, the side resistance of annealing furnace oil removal will increase, or even fall off. So there is adhesion.
  第六,选择合适的退火体系,铝箔的退火温度不宜过高。
  Sixthly, the annealing temperature of aluminum foil should not be too high.
