Abstract

1384719 Rolling mills MORGAN CONSTRUCTION CO 19 Dec 1972 [22 Dec 1971] 58539/72 Heading B3M [Also in Divisions G1 and G3] The tension in a metal strip 10 (Fig. 1) passing through four consecutive stands 2-8 of a rolling mill is determined between each pair of stands by measuring the force required to deflect the strip by a predetermined small distance from its normal straight position, using a bell crank 46 (Fig. 2) which is displaced into the measuring position by a piston 32 energized by fluid pressure applied to a cylinder 18. The force is measured by a load cell 38 comprising strain gauge resistors connected to a bridge circuit. The roll speeds are adjusted, manually or automatically, to produce the desired tension in each section.
