Abstract: 1,022,963. Rolling. YOUNGSTOWN RESEARCH & DEVELOPMENT CO. Nov. 19, 1963 [Nov. 21, 1962], No. 45523/63. Heading B3M. [Also in Divisions G1, G3 and H2] The boring of a small diameter work-roll 5, Fig. 2, is controlled by varying the armature currents of electric motors driving backing rolls 1, 2. The roll-pass for a material 6 is formed between the roll 5 and an intermediate roll 3 driven by the backing roll 1. The roll 5 is driven by the backing roll 2 through an intermediate roll 4. The boring of the roll 5 is limited by safety bars 25a, 25 carrying conduits 22, 22a having nozzles 26, 26a which direct jets of air on to the roll 5. The resultant back pressures vary with the roll position and are applied to a transducer wherein the difference between the back-pressures cause movement of a diaphragm 30 positioning a magnetic core 39 of a linear variable differential transformer 28. The transformer 28 has a primary 41, energized from a 1 kc. source 75, and secondary coils 42, 43 connected in series opposition so that the voltages induced in the secondaries are equal when the back-pressures are equal. In an alternative arrangement for sensing the deflection of roll 5, Fig. 3 (not shown), electromagnetic inductors are mounted on opposite sides of the roll and connected in a bridge circuit with the balance of the bridge being improved by an RC network. In another arrangement, Fig. 5, not shown, the deflection of the roll 5 is sensed by two proximity transformers wherein the magnetic flux linkage between the primary and secondary windings is partially through the roll. The outputs of the secondaries windings are connected in opposition and fed to an amplifier. In modified arrangements, Figs. 5 and 6 (not shown), a single inductor or transformer is used. Each inductor comprises a circular core, made of powdered iron, with a coil on the centre leg the inductor being sealed by epoxy resin. The roll 5 is made from steel or tungsten carbide, for which the ferro-magnetic properties reside in a cobalt binder. In a further arrangement, Fig. 7 (not shown), a nozzle is held against the roll by a spring, a nozzle movement being sensed by movement of a magnetic core of a differential transformer as shown in Fig. 1. Oil is passed through the nozzle to provide a film between the nozzle and roll so as to prevent marking of the roll. In a tandem arrangement of rolling mills, Fig. 8 (not shown), the position of the small diameter work-rolls are reversed in the two mills so that both sides of the strip 6 receive a major portion of reduction in one pass.
