摘 要: 用冷轧代替冷拔生产21-4N钢是一种新方法。通过冷轧21-4N圆钢的实验得出:21-4N圆钢经冷轧后断面椭圆度≤0.1mm,且沿轧件全长直径趋于均匀,达到冷拔的精度;采用工艺润滑可以进一步提高冷轧圆钢精度:经冷轧后组织中的析出相变小变多,且冷轧后强度和硬度增高,延伸率降低。 AbstractProducing 21-4N steel by cold rolling instead of cold drawing is a try.The result shows that the section ellipse degree of bar of 21-4N steel is less than 0.1mm,and the bar diameter is rath- er uniform along with the rolling direction after cold rolling.which has attained the some accur- acy as that of the cold drawned of 21-4N and can improve it more when lubricating.
