Adjustment method for rolling center line of continuous rolling mill for seamless steel tubes

The invention provides an adjustment method for a rolling center line of a continuous rolling mill for seamless steel tubes; the rolling center line of the rolling mill is measured by taking the center line of a stop rack as the reference, and the adjustment direction and the adjustment amount of a rack are further determined. Compared with the prior art, the adjustment method provided by the invention is capable of ensuring the center line of the rack to be parallel with the rolling center line by adopting a method that the center line of the rack of the rolling mill is parallel with the center line of the stop rack, and therefore not only is an adjustment value small, is the adjustment accuracy high and can deviation not be accumulated but also the adjustment method is simple and easy to implement, the construction speed is fast, and the efficiency is high; the defect that larger deviation is generated between the center line of the rack and the rolling center line after adjustment by utilizing the traditional adjustment method for the rolling center line of the continuous rolling mill is overcome; in practical production, the adjustment method can be widely applied; not only are the progress and the quality ensured but also the equipment adjustment accuracy is ensured.
