1、控轧控冷工艺的技术研究及应用李薇（沈阳工业大学材控12级，17835289）[摘 要 ]介绍了控轧控冷的机理，控制轧制的优缺点。控制轧制与传统轧制的比较；由于各种钢种以及用户对产品性能的要求越来越高，使得控制轧制应用的必要性逐渐增大。 高速线材轧制中应用的主要是控制冷却工艺，该技术的核心是通过对加热温度控制、轧前水冷、精轧机内水冷、精轧机组后水冷、风冷线温控等参数实现控制轧制。由于线材的轧制速度相比其它都较高，在生产中产生的变形热也相对较高，实现控制冷却尤为重要，控制加热温度，在轧制的道次间使用间断冷却，保证产品的综合性能。 在
2、板带材中应用的控制轧制技术的核心是在轧制过程中通过控制加热温度、轧制过程、冷却条件等工艺参数, 改善钢材的强度、韧性、焊接性能。该项技术问世20 年来,经过不断地完善和巩固, 已经逐步扩展应用到海洋结构用钢、线棒材、型材等各个领域。[关键词] 控轧控冷机理；特点；必要性；工艺参数；扩展应用高速线材；加热温度；控轧控冷Abstract :Describes the mechanism of controlled rolling and cooling to control the rolling of the advantages
