Controlling method for shape of pipe in continuous pipe rolling mill
专利汇可以提供Controlling method for shape of pipe in continuous pipe rolling mill专利检索，专利查询，专利分析的服务。并且PURPOSE:To carry out always stable, precise rolling work, by installing a device for continuous measurement of the outer diameter of the pipe on exit sides of the middle and the downstream stands, and by carrying out the feed-forward and feedback control for obtaining suitable number of rotation of the roll, and for correcting it. CONSTITUTION:In case of the rolling mill consisting of eight stands from the first to the eighth, the outer diameter measuring device is installed on the exit side of the fifth stand; the outer diameter D5' is measured for every constant micro-time interval; and then, the suitable roll speed V05 is obtained from this D5' and the previously designed D05, according to the formula. Then, the roll speed for the sixth stand and following stands are obtained similarly. The correction is carried out so as to accelerate in case of the overfill, and to decelerate in case of the under- fill. The outer diamteter measuring device for use of the feedback, being installed only on the exit side of the final stand, satisfactorily serves the practical purpose When the outer diameter D' measured in the final stand differs less than 1% from the ideal outer diameter D0, the feedback for correction of the outer diameter is not dispatched.，下面是Controlling method for shape of pipe in continuous pipe rolling mill专利的具体信息内容。
