Abstract

PURPOSE:To obtain a steel pipe of the outside diameter conforming exactly to the target stably by forecasting such plug position pattern of a reeler mill at which the quantity of thickness reduction in the reeler mill is the quantity of prescribed outside diameter expansion. CONSTITUTION:The signals for the temp. on reeler mill inlet side by a thermometer 20, the shell outside diameter by an outside diametermeter 27 on reeler mill outlet side, the rolling load by a load cell 28, and the plug position by a plug position detector 26 are inputted to a control arithmetic device 21. From here, the plug position control signal corresponding to the plug position pattern is outputted to a plug position control device 29, and a plug 13 is moved forward and backward by a plug position regulator 25. The rolling reduction and the like is inputted from a screw-down position meter 24 to the device 21 which outputs a screw-down control signal to a screw down control device 23 in accordance with this, and controls the positions of rolling rolls 10, 10' by means of a screw- down device 18 and a screw-down screw 17.
