摘要
文章阐述了宝钢高韧性管线钢的生产实绩;为保证45°向性能达到工程要求所采取的措施与成效;进一步验证了45°向性能弱是控轧控冷钢在热连轧中的典型特征;指出厚规格高韧性管线钢的生产难点在于热连轧。
Tangible achievements in production of Baosteel's pipeline steel with high toughness are described. In order to guarantee the properties in 45?rolling direction, measures have been taken to meet the requirement of the projects. The weak properties in 45皉olling direction are proved to be typical characteristics of the steel under controlled temperature and rolling in hot tandem rolling. Difficulties in manufacturing heavy gauge pipeline steel with high toughness lie in the process of hot tandem rolling.
