Abstract

681,373. Rolling; drawing. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Oct. 4, 1950 [Oct. 11, 1949], No. 26078/49. Class 83 (iv). [Also in Group XXXV] In a method of producing sheet or strip material by rolling or drawing through dies, the thickness of the strip is maintained substantially constant by continuous adjustment of the tension applied to the sheet or strip in accordance with variations in the thickness concurrently issuing from the rolls or dies, or the loading on the rolls or dies. In a coldrolling mill 10 for metal strip 24 in which tension is applied to the strip between the unwinding and winding reels 11, 12 the tension is adjusted to maintain the thickness of the strip substantially constant by varying the torque of an electric motor 14 driving the winding reel 12 in accordance with the variations in load on the upper work roll 15. The upper chocks 16 are loaded by screws 18 through interposed steel cylinders 19 having electrical resistance strain gauges 20 on the sides and the motor 14 is controlled through an electronic amplifier 21 supplied with current passing through the strain gauges. In a modification in which a strip is drawn between two dies 31, 33, Fig. 5, the upper die carrier 34 is loaded in the same manner as the upper roll chocks and the drawing tension is similarly controlled.
