| Abstract: | 55CrMnA spring flat steel was developed and produced by adopting such processes as oxygen top-blown converter,LF refining,continuously casting into small billets,bar and shape mill. Such measures as catch-carbon method,steady end point control,complex deoxidation process of molten steel,LF refining process,optimized continuous casting control process,right rolling temperature and cooling system were adopted and every property indexes of 55CrMnA spring flat steel accorded with the requirements of GB/T 1222—2007. |
