PURPOSE:To produce a thin strip which is uniform in a width direction easily and stably in a large amt. by inclining the clearance between a roll and a nozzle horizontally so as to minimize the deviation in the broadside thickness from the thickness distributions obtained by measurement of the thicknesses at >=2 points in the width direction. CONSTITUTION:The molten metal ejected from a nozzle 7 is quenched on a rotary cooling roll 8 to solidify to a thin strip 9. Bearing boxes 14 support the roll 8 with the bearings thereon and are supported turnably in chocks 15 on the spherical surfaces. The boxes are moved by DELTAS1, DELTAS2 horizontally with respect to a nozzle 7 by cylinders 17 connected by means of pins 16. Thickness gages consist of 12A, 12B which measure two points in the width direction of the plate. The values measured therewith are transmitted to an arithmetic controller 18, which operates the roll positions where the prescribed thickness is obtained and the deviation in the broadside thickness is minimized. Said positions are transmitted to a hydraulic controller 19 for positions. The controller 19 drives a servo valve 20 to introduce oil pressure into the cylinders 17, whereby the precise control of the positions is executed. Detectors 22 for cylinder positions feed the position signals back to the controller. |
