Abstract

1407073 Bonding metals; continuous casting USS ENGS & CONSULTANTS Inc 16 Aug 1972 [16 Aug 1971] 38276/72 Headings B3E and B3F Apparatus for straightening a continuous casting which has a curved set on leaving a curved roll-rack comprises upper and lower series of closely adjacent rolls defining a pass for the casting, one roll 18 of the lower series contacting the lower face of the casting at the point dividing the straightened portion from the still curved portion and sustaining the downward thrust of the bending force, two idler rolls 16a, 20a, of the upper series one either side of the roll 18 and each sustaining half the upward thrust of the bending force, driven upper rolls 17a, 19a between rolls 16a, 20a either side of roll 18 mounted so as to be vertically movable, and idler rolls 16, 17, 18a, 19, 20 located oposite the named rolls and journalled on fixed axes. Roll 18 may be driven or an idler and has a back-up roll 25. Fig. 1 shows further vertically movable driven rolls 15a, 21a, 23a, and further idlers 15, 21, 22, 22a, 23, 24, 24a journalled on fixed axes. Suitable roll mountings are described, Figs. 2 and 3 (not shown), in which the rolls are journalled in bearing chocks slidable vertically in keyways in vertical frame members connected by transverse members 50, 36. The chocks of the lower rolls rest on ledges 46, except that back-up roll 25 is supported on loads cells 29 to give continuous measurement of reaction forces. Fixed upper roll chocks are located below fixed transverse members 36 and are adjustable in position by packing shims. Displaceable upper roll chocks are held down by yokes 53 connected to a fixed base by double acting hydraulic pistons and cylinders.
