Abstract

The lower roll chocks and hence the lower roll 4 of a stand 1, 11 are hydraulically adjusted by jacks 6 and 61 by means of cylinders 7 whose plungers are operated by motors 9 and 91 through gearing 8 and 81. The pressure in line 11 is measured by a meter 22 and a corresponding electrical signal is sent to a controller 21. Here the signal is compared with one indicating the positions of equalizing pistons 13 and 131, which again depend on the pressure in lines 11, 111, and any difference is fed to a solenoid valve 15 which controls the position of a piston 14a and hence the pistons 13 and 131. Thus any elastic deformation of the stand is compensated for when rolling a product.
