Embodiment Construction
[0018] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0019] See figure 1 , is a structural schematic diagram of an embodiment of a method for calibrating the centerline of the guide rail according to the present invention. Under normal circumstances, calibration is performed after each overhaul. Since the guide rail is easily deflected when the strip steel is rolled over 18mm, it is therefore easy to roll over 18mm. After the steel is stripped, the offset of the guide ruler relative to the transmission side and the working side should be corrected in time to ensure the centering of the guide ruler 1. The specific operation steps are as follows:
[0020] 1) Measure the width L of the extension strip 2 in the middle of the guide ruler, the distance L2 between the edge of the extension strip 2 driving side and the guide plate 3 on the transmission side, the distance L1 between the edge of the extension...
