    摘要： Herein disclosed are dry type continuous wire drawing process and machine which can enhance the productivity by conducting in-line a wire drawing operation including the steps of flaw detection and wire repair. The wire to be drawn is mechanically descaled and is then coated with a lubricant. The wire thus coated is drawn through a drawing die. At the coating step, the wire is first coated with lime powder and then with metallic soap. Thus, the wire is drawn under dry and continuous conditions. After the drawing operation, a flaw in surface of the wire is detected. The surface flaw is located from the running speed or distance of the wire and the detecting instant. The surface flaw located is removed. The resultant wire is wound up. The surface flaw which cannot be removed is marked. An internal defect in the drawn wire is also detected with ultrasonic waves. The internally detected portion is also marked. All of the steps thus far recited and others are conducted in-line.

    摘要翻译： 这里公开的是干式连续拉丝工艺和机器，其可以通过在线进行拉丝操作来提高生产率，包括探伤和线材修复的步骤。 待拉制的线材是机械除锈的，然后用润滑剂涂覆。 这样涂覆的丝线通过拉丝模头拉出。 在涂层步骤中，首先用石灰粉末涂覆金属丝，然后用金属皂涂覆。 因此，在干燥和连续的条件下拉丝。 在绘图操作之后，检测到导线表面的缺陷。 表面缺陷位于线的运行速度或距离以及检测时刻。 去除表面缺陷。 所得到的线被卷起。 标有不能清除的表面缺陷。 拉丝的内部缺陷也用超声波检测。 内部检测到的部分也被标记。 到目前为止所有的步骤和其他步骤是在线进行的。
