| This text is to clarify how to improve the mechanical properties, improve the quality of wire, improve the quality of wire rope, reduce the manufacturing cost and reduce the material consumption by the way to change the four tower rollers transaction of the rotating wet drawing machine to be two tower rollers transaction, change the ratio of rollers to change to partial reduction ration of the drawing machine and improve the drawing condition. It is to increase the products range and the market share by the way to change the equipments of the drawing machine with a dry drawing double blocks to increase the inner diameter range.The life time of the revised wet drawing machine is improving after the trial producing of half year, at the same time, the machine now is in less trouble, less repair time and repair cost and more production efficiency. |
