Abstract
The invention discloses a method for solving cracks of head and tail blanks of a 10Cr17 steel grade. The method for solving cracks of the head and tail blanks of the 10Cr17 steel grade comprises the following steps of: keeping the temperature of the head and tail blanks of the 10Cr17 steel grade at 200-400 DEG C, and sequentially carrying out rough grinding and accurate grinding on the surfaces of the head and tail blanks by using a grinding machine; and when the temperature of the head and tail blanks is lower than 150 DEG C, stopping grinding. And during rough grinding, the current of the grinding machine is 250-350A. And during accurate grinding, the current of the grinding machine is 120-200A. According to the method for solving cracks of the head and tail blanks of the 10Cr17 steel grade, the problem that cracks are locally generated on the surfaces of the 10Cr17 head and tail blanks is solved, the surface peeling phenomenon of subsequent hot rolled steel coils is completely eradicated, the pickling first-grade product rate is remarkably increased, and therefore, the product quality is improved, and economic benefits are greatly improved. According to the method for solving cracks of the head and tail blanks of the 10Cr17 steel grade, the grinding frequency and the grinding rate can be reduced, cracks of the head and tail blanks are avoided, and the product cost is reduced.
