摘　　要：介绍了在X70钢工业试验研究中 ,采用两种工艺路线成功地生产了 6炉X70钢。并且通过对比确定最佳工艺路线和操作工艺参数以及对有害元素的控制措施 ,为今后批量生产提供了可靠依据。During the industrial scale experimental studies 6 heats of X70 steel have been produced successfully through two process routes, and thereupon the best process route and operating process parameters as well as measures to control the detrimental elements have been determined by comparison. The results can be used as the reliable guide for the future production.
