摘要
在试验轧机上对一种非调质N80套管进行了改善强韧性能的试验研究。结果表明,采用合适的轧后控冷工艺或增加奥氏体未再结晶区的累积变形量均可提高N80套管钢的强韧性能,如果二者同时采用则效果更佳。采用上述结果进行了工业化批量生产,所获得产品的强度和韧性均较试验前有较大的提高。
Experimental study was carried out for improving strength and toughness of non-quenched and tempered casing tube NS0. The results show that strength and impact toughness can be improved by adop- ting appropriate controlled cooling process after rolling or increasing cumulative deformation in the auste- nitic non-recrystallization zone, and better performance can be achieved with the combination of these two methods. The commercial production proves that the strength and impact toughness of the products so pro- duced can be noticeably enhanced.
