保定市冷拔无缝钢管厂

制定管材冷轧冷拔生产(见管材冷轧冷拔机组)的工艺流程及变形规程。在管材冷轧冷拔机组中，在产品投产以前必须对它的生产工艺流程、变形参数和加工设备选择等有一个明确的规定，作为组织生产和进行操作的依据，这项工作就是编制工艺程序表。根据所采用的冷加工方法，工艺程序表可分为拔制表(采用冷拔变形)和轧制表(采用冷轧变形)以及轧制和拔制表(采用冷轧冷拔两种方式变形)，由于管材冷轧冷拔生产特点是多工序和循环性，而且品种很多，为了使生产能合理和有秩序地进行，编制工艺程序表是很重要的。工艺程序表的内容包括有：管料尺寸，变形方式和道次，每道次的变形量及变形后管子尺寸，选用的加工设备、辅助工序和工模具类型等。编制工艺程序表时，除根据材料加工特性和管子技术条件外，还必须考虑具体的生产条件。各冷拔冷轧机组都有根据自己生产条件制定的工艺程序表，并且在生产实践中不断地进行修改和完善。

The process flow and deformation regulation of cold - drawn tube production (see tube cold rolling and cold drawing unit) are formulated. In pipe cold rolling and cold drawing unit, there must be a clear regulation on its production process, deformation parameters and processing equipment before it is put into production. As a basis for organizing production and operation, this work is to compile process schedule. According to the cold processing method, process chart can be divided into pull tab (deformation by cold drawing and rolling (table) by cold rolling and rolling) and pull tab (deformation by cold rolling and drawing in two ways), because the production characteristics of cold rolling and drawing of tube is multi process and circulation, and many varieties, in order to make the production reasonable and orderly, the preparation of program is very important. The contents of the process schedule include: pipe size, deformation mode and pass, deformation per time and size of pipe after deformation, selection of processing equipment, auxiliary process and mold type. In addition to the processing characteristics of the material and the technical conditions of the tube, the specific production conditions must be considered. All cold - drawn cold rolling mills have the process schedule according to their own production conditions, and they are constantly modified and perfected in the production practice.
