摘要/Abstract

摘要： 分析了常规锻造-拔长,镦粗-拔长,镦粗-拔长-镦粗-拔长,镦粗-换向拔长 4种锻造方式对叶片钢1Cr12Ni2Mo2VN(%:0.10C，0.17Si，0.74Mn，0.014P，0.002S，11.8Cr，2.43Ni，1.65Mo，0.32V，0.0352N)2.5t电渣锭锻造成Φ220 mm棒材横向冲击韧性的影响。结果表明,单道次大压下量的镦拔锻造及镦拔次数的增加可显著提高叶片钢的横向冲击韧性,2镦2拔后的棒材经1050℃1h油冷,660℃2h空冷后的横向冲击功为141 J,横纵向冲击值比可达90%以上,组织均匀,晶粒细化。

Abstract: The effect of four forging methods i. e. conventional forging-stretching, upsetting-stretching, upsetting-stretching-upsetting- stretching and upsetting-changing direction stretching on horizontal impact toughness of Φ200 mm bar products forged from 2.5 t ESR ingot of blade steel 1Cr12Ni2Mo2VN (/% : 0.10C, 0.17Si, 0.74Mn, 0.014P, 0.002S, 11.8Cr, 2.43Ni, 1.65Mo, 0.32V, 0.0352N) has been analyzed. The results show that the upsetting-stretching forging with single pass large reduction and increasing upsetting-stretching forging times are available to obviously increase the horizontal impact toughness of blade steel ； with upsetting-stretching-upsetting-stretching process the horizontal impact energy of bar product heated at 1050 ℃for 1 h, oil cooling and at 660 °C for 2 h, air cooling is 141 J, the ratio of horizontal and longitudinal impact energy is more than 90% , and steel structure is uniformity with finer grains.
