Abstract

895,929. Rolling. MOELLER & NEUMANN G.m.b.H. Oct. 31, 1960 [Nov. 5, 1959]; No. 37295/60. Class 83 (4). In a rolling mill required to operate with close thickness tolerances, the frame parts such as tierods 3, Fig. 3, are hydraulically stressed under tension by amounts which are automatically controlled according to the roll pressure so that the total tension and elongation in the tie-rods remains substantially constant. In one example in which the tie-rods 3 are tubular and elongated by internal hydraulic pistons 10 through thrust rods 11, the roll pressure as measured by transmitters 26 under the clamping nuts 9 and indicated at 31 is added by a computor 32 to the corresponding hydraulic pressure in the pistons 10 as indicated at 33. The total is compared in the computer 32 with a pre-set value to produce a signal indicated at 37 which is passed to a regulator 38 and re-sets the pressure in the piston 10 to maintain constant tension in the tie-rods 3. The pre-set signal, which is set manually at control 43 may have a superimposed correction for roll flexure under load and is provided by a computer 44 controlled in dependence of the roll pressure. Further corrections may be made according to measured values of thickness by signals from instruments disposed after the stand. In order to prevent sudden changes in thickness due to the response time of the system during multipass rolling when a new core enters the rolls, photo-cells 45-47 are placed in front of the mill at distances corresponding to the response time and detect the approaching core ends. The photo-cells act through devices 48-50 to reduce the hydraulic pressure by predetermined increments, equivalent to the roll pressure changes. The roll gap is initially set by annular screw-downs 22, 23, the upper member 22 being rotatable through a gear 24. Springs 13 between the lower screw-down member 23 and the lower roll chock 21 maintain the rolls and frame parts in a separated condition against the clamping nuts 9. In modifications the hydraulic piston and cylinder assembly 12, 16, Fig. 2, may be annular and disposed concentrically of solid tie-rods 14. When the automatic hydraulic pre-stressing system is not required, spacers (not shown) may be placed between the roll chocks or frame parts so that the stand parts are prestressed to reduce elongation.
