CONSTITUTION:A shell is rolled by a pair of rolls 2a and mandrel bar 4 and the thickness of a pipe stock 3 is adjusted by four pieces of hydraulic cylinders 5. The hydraulic cylinder 5 is equipped with a displacement gage 12 to detect the position of a ram 11 and a load cell 8 to measure a rolling load and the respective signal is transmitted to a rolling reduction controlling circuit 21. The roll gap of upper and lower rolls 2a is set with inputting from a computing device 23 incorporating the set program to the circuit 21, which controls the pressure of the cylinder 5 by transmitting a signal to a servo valve 24. In this way four pieces of cylinders 5 are controlled independently and the number of holding mandrel bars 4 together with the thickness deviation can be reduced.

摘要： PURPOSE:To enable an accurate measurement of the mill rigidity of a three roll rolling mill by a simple method by feeding test flat plates at the same time to bite them between adjoining rolling roll-flanges and obtaining a rolling load and the amount of mill spring. CONSTITUTION:A caliber 12 is formed by the three rolling rolls 11 of a three roll mill 10. Respective test flat plates 13 are made of aluminum, etc., and are fixed to the positions rotated mutually by 120 deg. with the aid of a fixture 15 capable of passing through the inside of the caliber 12, and are made possible to be bitten into the gaps between flange parts 14 of the rolls 11 at the same time. The width W of the plate 13 is made equal to or slightly smaller than the width W1 of the flange part 14. The gas G between the flange parts 14 before rolling is measured first, and then three pieces of the plates 13 are bitten at the same time to roll them by the rolls 11 in order to measure a rolling load P. Further, the thickness (t) of plate 13 after rolling is measured to operate the difference between the gap G and the thickness (t), and the increased amount DELTAh0 of each gap G is obtained to obtain a component projected to the draft direction i.e. the amount DELTAh of mill spring in the draft direction of the roll 11. The deformation degree of the mill 11 in the draft direction of the roll 11 i.e. a mill rigidity K is obtained basing on the DELTAh and the rolling load P.

摘要： PURPOSE:To equalize the wall thickness of pipe in its longitudinal direction by performing rolling while continuously reducing the speed of a mandrel bar, from the time the rolling is started until the time it is finished, within a range shown by a prescribed equation. CONSTITUTION:A mandrel mill is constituted by arranging the roll axes of adjoining stands in state of mutually shifting the roll axes by 90 deg. in the plane perpendicular to a rolling axis. The speed of a mandrel bar at the time of starting rolling, that is when the front end of a hollow pipe stock is bitten by the 1st stand, is represented by vB0, and the speed of mandrel at the time of finishing the rolling, that is when the rear end of said pipe is passed any one of the stands after the 2nd stand, is represented by vB1. In rolling, the speed of mandrel bar is continuously decreased from the time the rolling is started until the time it is finished while maintaining the speed ratio vB1/vB0 within a range shown by the inequality (I). In this way, the wall-thickness change, due to the temperature change in the longitudinal direction of a pipe stock, is made uniform.
