摘　　要：为了研究热轧(HR)工艺状态Q550D板性能的关键因素,提高HR状态Q550D板的综合合格率,将工艺点控制方法应用于零件控制和HR轧制。结果表明,碳含量、冷却温度、温度均匀性是Q550D HR状态性能的关键组成部分。控制工艺后的HR状态Q550D具有良好的焊接性能和较低的屈服强度比。HR状态合格率提高到90%,节省了大量回火工艺。In order to study the key factors of the performance of Q550D plate in hot rolling(HR)process state and improve the comprehensive qualification rate of Q550D plate in HR state,the process point control method is applied to part control and HR rolling.The results show that carbon content,cooling temperature and temperature uniformity are the key components of Q550D HR state performance.The HR state Q550D after controlled process has good welding performance and low yield strength ratio.The qualification rate of HR state is increased to 90%,saving a lot of tempering process.
