DISCUSSION ON PRODUCTION OF VANADIUM-MICROALLOYING STEEL IN CSP LINE
-
摘要: 分析了V微合金化钢的强韧化机理及CSP生产线的工艺特点,探讨了V微合金化技术在CSP生产线应用的可行性和应注意的主要问题。V微合金化钢控轧控冷工艺技术特点是再结晶轧制与加速冷却相结合,而这一控制轧制特点正是CSP工艺的特征和优势。国外CSP线在投产之后已成功将V微合金化技术应用于该领域,并形成了不同系列。Abstract: The strengthening and toughing mechanism of vanadium-microalloying steel and the technological trait of CSP line are reviewed.The feasibility of applying vanadium-microalloying in CSP line and some noticeable problems are discussed.The technological trait of controlled rolling and accelerated cooling for vanadium-microalloying steel is the integration of RCR and AC,and it is regarded as the characteristic and advantage of CSP line.
