Abstract (en)
There is provided a method for controlling sizing mill of a pipe or tube in which, when a front or rear end of a pipe or tube 1 is rolled by each stand 2 of a sizing mill, the rotational speed of rolling rolls 21 provided to each stand is controlled. The rotational speed control start timing of rolling rolls provided to a predetermined stand is corrected based on the thickness measured value of the front or rear end of the pipe or tube measured at the output side of the sizing mill.
