钢丝在拉拔过程中,特别是在多道次连续拉拔过程中,由于形变摩擦作用会使其温度不断升高。这种温度升高到一定值以后,会影响钢丝的质量。为了有效地降低这种温度,除了采取对钢丝进行直接水冷、模盒水冷等措施外,还必须对拉丝机卷筒进行水冷。在卷筒的水冷中通常采用的是“内壁” Steel wire in the drawing process, especially in the multi-pass continuous drawing process, due to the role of friction deformation will make its temperature rising. After the temperature rises to a certain value, it will affect the quality of the steel wire. In order to effectively reduce this temperature, in addition to the direct water-cooled steel, mold boxes, water cooling and other measures, but also must reel drawing machine water-cooled. Commonly used in the water-cooled reel is the “inner wall”
