【摘要】 结合我国16Mn钢目前的生产实际和普遍存在的问题,在实验室条件下研究了加热温度、终轧温度、道次压下率、总压下率、形变量分配和轧后冷却速度等热加工参数对16Mn钢板组织和性能的影响,并与正火处理的作用相比较。从这些试验结果得到了一套较为理想的16Mn钢的热加工参数,用这套工艺参数加工的16Mn钢板,晶粒组织均匀细小,强韧性好,因此可以省掉正火处理。更多还原

【Abstract】 In connection with the present production practice and generally existing problems of 16Mn steel plate in our country, we have investigated under laboratory conditions the effect of hot-working parameters such as reheating temperature, finishing rolling temperature, pass reduction, total reduction, distribution of deformation and cooling rate after rolling, etc. on the micro-structure and properties of 16Mn steel plate as compared with the effect of normalizing treatment.Based upon the experimental results, a set of much better hot-working parameters for 16Mn steel has been obtained. The 16Mn steel plates worked with these parameters possess uniform and fine grain size as well as good strength and toughness. Thus normalizing treatment can be omitted.更多还原
