摘要
概述了快速冷却及直接淬火在提高板带材性能及钢种开发方面的发展应用情况,并介绍了热轧带钢的新型控制冷却技术———超快速冷却(UFC)。目前,UFC的冷却速率已超过300℃/s。UFC技术能明显提高带钢的强度和韧性、改善材质性能。还描述了UFC装置的应用实例及在开发超级钢、多相高强钢、相变诱导塑性钢等高附加值钢铁材料方面的应用潜力。随着先进钢铁材料开发的需要,新的控制冷却技术已由传统的对轧后开冷、终冷温度的控制向基于连续冷却转变CCT曲线的相变要求而对板带整个冷却过程的微观组织相变控制方向发展。
The application of accelerated cooling technology （ACC） and direct quenching （DQ） to the plate production was reviewed. The ultra fast cooling （UFC） system which the cooling rate can be over 300 ℃/s for hot strip was described. The laboratory results using UFC demonstrated that it could upgrade the strip properties in yield and tensile strengths. Some application examples of UFC and the potential for the production of high strength steel grades like multiphase HSS, TRIP and so on were introduced. In order to meet the requirement of the advanced steel materials,The new controlled cooling technology should be oriented towards the control of the phase transformation on the run out table based upon continuous cooling transformation （CCT） diagrams.
