摘要
本文对国内外屈服强度为690MPa及以上级别超高强钢的开发进展及生产工艺进行了对比分析,结果表明,采用直接淬火及在线淬火+回火工艺可以简化生产工艺、降低生产成本。
The development progress and production processes of higher than 690MPa ultra high-strength plate at home and abroad were analyzed. The results show that applying direct queching tempering and online queching＋tempering processes can simplify technology and reduce production cost.
