Title: Method for detecting and controlling tension in rolling of pipe material
Inventor: HATSUTORI MASASHI
IPC: B21B37/00
Filed: 1984-04-17
Abstract: PURPOSE:To detect exact tension on a pipe material by calculating the thrust coefft. of the pipe material and mandrel bar from the rolling load of a caliber roll pair and the current, voltage and rotating speed of motors for driving the caliber rolls and retainer. CONSTITUTION:The rolling torque G of the caliber rolls 3 and the holding power TBO of a retainer 5 are preliminarily calculated from the current I, voltage V and number of revolution omega of the motors 6, 7 for driving the retainer 5 and the rolls 3 in the stage of traveling the mandrel bar 2 inserted into the pipe material 1 to the caliber rolls 3 by the retainer. The initial thrust coefft. is calculated when the material 1 is bitten into the No. 1 stand and the thrust coefft. during rolling operation is determined by a correction equation. The tension on the pipe material in each stand is then calculated. The error from the target tension of the material 1 is compensated by proportional integration and the correction quantity for the peripheral speed of the rolls 3 is calculated by the prescribed equation. The roll peripheral speed of the No.i+1 stand is corrected by said correction quantity and the backward slip of the No.i+1 stand is changed, by which the tension on the pipe material is so controlled as to approach to the target tension.
