十三、拨制工艺安排及拔制表的计算 1.拔制工艺的安排在安排工艺和编制拔制表时,必须从高产、优质、低成本及冷拔车间内各设备的负荷均衡等方面出发,应考虑到影响拔制过程的一些因素,如拔制的钢种、钢管的热处理情况、钢管的品种及各项准备工序的质量、润滑情况以及使用的拔制工具、拔管机能力等等。为使冷拔管产量增加,成本降低和得到高质量的产品,在编制拔制表时最主要的应该正确地根据金属的强度极限来选用管料的尺寸和每道次的压下率,以便拔制道次尽可能减少。
XIII. Dialing process arrangement and drawing table calculation 1. Arrangement of drawing process When arranging the process and drawing the drawing table, we must start from the aspects of high output, high quality, low cost and load balance of each equipment in the cold drawing workshop Departure, should take into account the drawing process to take into account some of the factors that affect the drawing process, such as drawn steel, heat treatment of steel, steel pipe varieties and the quality of the preparation process, lubrication and the use of drawing tools, pipe pulling machine capabilities Wait. In order to increase the production of cold drawn tube, reduce the cost and get high quality products, the most important thing in the preparation of the drawn table should be based on the strength of the metal to choose the size of the tube material and the reduction of each pass, in order to Draw the order as much as possible.
