Abstract

1,269,939. Rolling. BRITISH IRON & STEEL RESEARCH ASSOCIATION. 4 July, 1969 [9 July, 1968], No. 32756/68. Heading B3M. [Also in Division G3] In a method of and an apparatus for rolling strip or plate material -the total rolling force during rolling is sensed and means for applying roll-bending forces and moments to the rolls are automatically adjusted an proportion to changes in the total rolling force to maintain the profile of the rolled material substantially constant. The apparatus comprises a four high roll stand having work-rolls 2 and backup rolls 3, the total rolling force F is applied by rods 7 to chocks 4 and is measured by a load-cell 8 which is connected to a computer C. The work-rolls 2 have a pair of jacks 11 acting on each one of-two chocks 10 axially spaced along the necks of-each workroll which provide the roll bending forces J and moments M which are also transmitted to the computer C. Profile parameters P*, Cl* related to the thickness of the strip at various distances from the centre line of the strip S are measured by a means 20 such as is described in Specification 1,231,008 and compared with the parameters P, Q, of the desired strip profile. When the desired profile is attained values of F*, J and M corresponding to that profile are stored in the computer. The measured values of J and 'M (J* and M*) are varied to compensate for any variation in the measured value of F (F*), thus maintaining the profile. Thereafter the values of J and M are varied to compensate for any variation in the measured total rolling force F* so that the strip -profile is maintained constant.
