Abstract

1370618 Rolling mills BRITISH IRON & STEEL RESEARCH ASSOCIATION 16 Dec 1971 [17 Dec 1970] 59985/70 Heading B3M A roll stand for rolling rods, bars or sections includes a pair of rolls (one at least of which is grooved) driven by a single driving motor 6 (Fig. 1), the motor being coupled to one roll, and the rolls being pressed together to transmit the drive frictionally from the driven to the undriven roll. The rolls may be pressed together by hydraulic units positioned between the lower chocks 8 and the housings 9. In a further embodiment (Fig. 3), the rolls are urged together by tie-rods 25, and the roll gap is adjusted by wedges 30, 31 connected together by adjusting screws 25. The co-operating surfaces of the wedges and chock may be curved to allow flexure of the rolls under load, and may be coated with an anti-friction lining of PTFE. The tie-rods exert a prestressing force of more than twice the rolling load. Belleville washers 27 allow the rolls to move apart under an overload. The work rolls may be crowned, and back-up rolls may be used.
