1results about How to "Reduce roll consumption" patented technology

The application discloses a method for reducing the grinding amount of a supporting roller of a hot continuous rolling mill, and comprises the following steps: A, confirming the use condition of the supporting roller on the machine; B, checking and recording the roller surface of the supporting roller off the machine; C, grinding the supporting roller on a grinding machine, and detecting by using a grinding machine eddy current flaw detector; D, detecting the hardness of the roller surface after grinding; E, checking the roller body surface, and detecting by using coloring flaw detection if necessary; and F, performing ultrasonic flaw detection on the roller surface. The method solves the problems of crack expansion and peeling of the supporting roller on the machine due to the too small grinding amount of the supporting roller and the waste caused by the too large grinding amount, so that the grinding amount is optimized, and the cost of the rolling mill is reduced.
