Abstract

1463523 Continuous casting USS ENGS & CONSULTANTS Inc 13 Sept 1974 [13 Sept 1973] 40087/74 Heading B3F [Also in Divisions B8 and F2] A horizontal roll-rack, e.g. following a straightening unit at the end of a curved guideway from a mould or from a vertical guideway, has at least idler roll section 23, 23a or 23b with a following driven-roll stand 24, 24a or 24b and has removable roll units each comprising at least one bottom roll 28 and one top roll 29 and mounted in opposed housings 26, 26a, Fig. 3; each top roll 29 can be removed independently of the bottom rolls, e.g. by removing pins 41 which interconnect lugs 39 and brackets 40 carried on chocks 32, 33 of the roll-units and using lifting-eyes 52 so that at the end of the rack, where the liquid core of the casting has solidified, top rolls are removed for the end to act as a simple run-out conveyer. Side guides 53 for the casting are mounted on the inside faces of the housings 26, 26a. At the top and bottom of each roll unit, a spacer bar 37, 35 interconnects the opposed chocks 32, 33. The top bar 37 has a hole at each corner for fitting over pins 48 on the housings 26, 26a for releasable securement by wedges 51 or for fitting over bolts on the housings for securement involving spring washers (see Division F2) for yielding mounting of the top roll. The heights of the rolls 28 and 29 are determined by shims 42-44. If a curved mould is not used, the vertical guideway and a bending unit may have driven rolls or separate pinch rolls may be employed. A flexible starter bar may be picked up by crane as it reaches a final run-out conveyer 18, or a rigid bar may be used.
