摘要: 12Cr2Mo1VR钢板生产的流程为100 t EAF-LF-VOD-CC-ESR-轧制工艺。电渣重熔过程中,采用熔速降低(160~180) kg/h及氮气保护等工艺;轧制过程采用低速大压下量轧制工艺;轧后采用650~700℃长时保温扩氢退火工艺;热处理采用930~950℃正火(加速冷却)+680~700℃回火工艺。生产的钢板表面质量良好,探伤级别满足NB/T47013.3-2015及第1号修改单TⅠ级要求,钢板成分、显微组织均匀,力学性能满足技术要求。

Abstract: The 12Cr2Mol VR steel plate production flow is 100 t EAF-LF-VOD-CC-ESR-rolling process. In the electroslag remelting process, the processes such as melting rate reduced by (160 ~ 180) kg/h and nitrogen protection are adopted ; low speed and large reduction rolling process is adopted in the rolling process ; after rolling, 650 ~ 700 °C longtime holding hydrogen diffusion annealing process is adopted. Normalizing at 930 ~ 950 °C ( accelerated cooling) + tempering process at 680 -700 °C are adopted during heat treatment. The surface quality of the produced steel plate is good. The flaw detection level meets the requirements of NB/T 47013. 3-2015 with No. 1 amendment T I rating. The composition and microstructure of the steel plate are uniform. The mechanical properties are stable to meets the technical requirements.
