Abstract

1449665 Rolling mills MORGARDSHAMMAR AB 11 Sept 1973 [11 Sept 1972] 42706/73 Heading B3M A strip rolling mill has pairs of roll stands 12 and 16 on either side of a main stand 14 both for reducing a strip 18 and for producing forward and back tension in the strip as it is rolled. The rolls 32, 34 in stand 12 apply a back tension to the strip and are only driven during initial threading of the strip. The rolls 36, 38 in stand 16 apply a forward tension and have their speed controlled in such a way as to control the reduction in the main stand 14. The strip reduction in the three stands is 10-40%, 40- 60%, and 1-10% respectively. The three stands are rigidly connected together to form a closed-loop force transmitting assembly. Coarse control of the screwdown in the stands is effected by mechanisms 58, 68 and 76, but fine control is made by adjusting the rolling speed in stand 16. The speed is varied according to the strip tension measured by gauges 116 between the stands, and may be automatically or manually adjusted.
