Method for removing original decarburization layer of initial rolled blank
The invention discloses a method for removing an original decarburization layer of an initial rolled blank. The initial rolled blank is a small square blank which is rolled into 150 * 150 by using a larger square blank of 320 * 480, primary peeling is carried out on the edge region of the small squa...

| description | The invention discloses a method for removing an original decarburization layer of an initial rolled blank. The initial rolled blank is a small square blank which is rolled into 150 * 150 by using a larger square blank of 320 * 480, primary peeling is carried out on the edge region of the small square blank, then the edge region and the face region are subjected to one-time integral peeling at thesame time, and the peeling depth is 0.85-1 mm each time. According to the method, the processed initial rolled blank is sampled to detect decarburization, the original decarburization is removed, theoriginal decarburization layer residue is not found, a SCM435-M wire produced by the blank treated according to the method meets the 12.9 class fastener testing requirements, and a 55SiCrA-M wire meets the suspension spring fatigue life testing and reaches 55 million unbroken.
本发明公开了一种去除初轧坯原始脱碳层的方法，所述初轧坯为使用320*480的大方坯轧制成150*150的小方坯，先对所述小方坯的楞部区域进行一次剥皮，然后对楞部区域和面部同时进行一次整体剥皮，每次所述剥皮深度为0.85-1mm。本发明处理后的初轧坯取样检测脱碳，原始脱碳已经去除干净，未再发现原 |
