Abstract:The paper induces technical requirements, process control key points and quality of actual product of single weight 50 t grade 174 mm 12Cr2MolR ( H ) steel plate is produced at Wugang. By C/Al combined deoxidation in the smelting process, ingot annealing at 900 ~ 940℃ for 28 ~ 32 h, rolling pass reduction 20 ~ 30 mm and using normalizing + accelerating cooling + tempering process, the plate structure is uniform, and the mechanical property and step-cooling embrittlement performance of steel plate reach technical requirements. Internal quality of steel plate is excellent. NDT meets NB/T 47013. 3-2015 and revised list No. 1 T1.
Keywords:12Cr2MolR(H) Steel Plate   Forged Ingot   Heat-Treatment   Mechanical Property  NDT
