Abstract

1,012,853. Rolling. LOEWY ENGINEERING CO. Ltd. April 2, 1964 [April 10, 1963], No. 14304/63. Addition to 955,164. Heading B3M. In an improved rolling mill of the kind described in the parent Specification, the housings 10 are prestressed by cylinders 13 which are slidable relative to fixed hydraulic rams 14 to urge rods 27, and hence the upper chocks 20, upwardly. The rods 27 pass through bores in the lower chocks 29. A further ram 18, slidable in each cylinder 13, urges the chock 19 upwardly to set the roll pass. The prestressing force is maintained a fixed amount greater than the rolling force by means of load cells 26, whose outputs activate a servomotor 29 and valve 30 to vary the prestressing force in cylinder 13. The load on the rods 27 and thus the roll pass is thereby kept constant. The pressure in cylinder 17 is adjustable by a motor driven screw 33 on which is mounted a ram 32. The hydraulic rams may be situated at the head of the housing, and-the prestressing and roll pass adjustment rams may be at opposite ends of the housing. The supporting rolls may be dispensed with, the working rolls then being mounted in the chocks 19 and 20.
