近些年来,线棒材生产热处理技术发展很快。现在不只是注重热处理本身技术和装备的研究,更重要的是,在线棒材的生产过程上,把热加工、冷加工、热处理尽可能地结合起来,以最少的工序和装备、最短的时间获得所需最佳产品(包括半成品)性能。这对于简化工艺流程,提高产品质量,提高生产率,节约能源具有十分重要的意义,因此世界各国努力致力于这方面的研究,在生产中取得了显著的效益。 目前线棒材生产的简省热处理技术有: (1)高强度螺栓和普碳钢丝线材的控轧控冷工艺 (2)线棒材TEMPCORE冷却工艺 (3)在线固溶化热处理工艺 (4)DLP在线热处理工艺
In recent years, wire rod production heat treatment technology developed rapidly. Now it is not just the study of heat treatment itself technology and equipment, more importantly, the combination of hot working, cold working, heat treatment as much as possible in the production process of the online bar, with the minimum process and equipment, the shortest time Need the best product (including semi-finished products) performance. This is of great significance to streamline the process, improve product quality, increase productivity and save energy. Therefore, all countries in the world are devoted to this research and have achieved remarkable benefits in production. At present, the wire rod production of Jane heat treatment technology are: (1) high strength bolts and carbon steel wire rod rolling controlled cooling process (2) bar wire TEMPCORE cooling process (3) online solution heat treatment process (4) DLP Online heat treatment process
