  • This invention relates to acontinuous-casting apparatus which embodies an improved curved roll-rack, and to the curved roll-rack itself as a subcombination.
  • the driven ,rolls serve to apply auxiliary tractive forces which assist in propelling the workpiece through the apparatus.
  • a curved roll-rack is a massive mechanism, yet it must be constructed with a high degree of precision in order not to damage the workpiece, which is delicate at this stage with its liquid core.
  • the rolls are subjected to extreme conditions fromboth the heat of the workpiece and the intense water sprays applied to theworkpiece to cool it and promote solidification. Hencethere is frequent need to remove and replace rolls. When rolls are installed, either originally or as replacements, it is of course necessary to position them accurately.
  • An object'of our invention is to provide an improved curved roll-rack in which the idler rolls are supported automatic positioning when replaced.
  • FIG. 7 is a fragmentary elevational view in the same plane as FIG. 5, but showing a modification.
  • our curved roll-rack includes a frame constructed of arcuate lower, middle and upper idler-roll support sections l0, l2 and 13 assembled in aligned end-to-end relation, a first fabricated base I member 14 located between the lower and middle secon column 17.
  • the supporting structure also includes similar columns and beamsat the opposite side of the roll-rack on which we mount similar fabricated base membersof opposite hand.
  • a straightener: 21 and a bending-roll unit 22 of any standard or desired construction are supported at the exit and entry ends respectively of the curved roll-rack.
  • the three frame sections l0, l2 and 13 preferably are all alike.
  • Each includes an opposed pair of side plates 23 and 23a and a plurality of transverse members 24 bolted to the side plates to form a rigid structure.
  • the inside faces of the side plates 23 and23a have raised pads 25 where each transverse member 24 is joined.
  • Each side plate has a concave edge along which we weld a series of machine pads 26.
  • Each pad 26 has a respective near-radial hole 27.
  • roll supports 28 A- further object is to provide'an improved curved I roll-rack in which the frame includes a plurality of idler-roll supporting sections and-base members serving both as supports forthe sections andas'housings for driven-roll stands.
  • a further object is to provide a curved roll-rack in and as housings for a of inverted T-shape to pads 26 with bolts 29 which pass through holes 27 and carry nuts 30.
  • Each support 28 spans two pads 26.
  • the supports carry clusters of bottom and top idler rolls 31 and 32, hereinafter more fully .described. We insert shims 33 between the pads 26 and the supports 28 to, adjust the position of the rolls 31 and 32 precisely.
  • the first and second base members 14 and 15 serve not only to support the ends of the frame sections 10, 12 and 13, but also as roll housings for bottom and top driven rolls 34 and 35.
  • Each side plate 23 and 23a. has a respective accurately located hole 36 near its exit end where the frame section isto be pivoted to a support.
  • the sideplate of the lower frame section 10 are pivoted at the exit end of thesection to the straightener 21 with pins which pass through holes 36.
  • These same side plates are bolted at the entry end of the seetion sto thefirst base member 14.
  • the side platesof the middle frame section 10 are pivoted to the first-base member 1 14 and bolted'to the second base member 15, while the side plates of the upper frame section 13 are pivoted to 'the second base rnember l5 and bolted :to the third base member' l6.
  • the bolted connection allows for thermal expansion of the parts.
  • FIG. 3 is a fragmentary top plan view on line IIIIII of FIG..2 Y
  • FIG. 4 is a side elevational view on a larger scale than FIG. 1 showing the mounting means for the idler roll clusters on the frame section;
  • FIG. 5 is a section on line V-V of FIG. 4;
  • FIG. 6 is a top plan view of a roll cluster, partly in section, on VIVI of FIG. 5;
  • each inverted T- shaped support has a flat cross bar 40, and an upright rail 41 of T shapc in cross section which extends radially from the concave edge of the frame section 10, 12 or 13 toward its center of curvature.
  • the aforementioned bolts 29 pass through the cross bar 40.
  • Each bottom idlcr roll 31 is journaled in a respective opposed pair of bearings 42.
  • the four bearings for the cluster of two bottom idlers are mounted in an opposed pair of chocks 43.
  • a bottom spacer bar 44 is bolted to the underside of the two chocks 43 and extends therebetween.
  • Each top idler roll 32 is journaled in a respective opposed pair of bearings 45.
  • the four bearings for a cluster of two top idler rolls are mounted in an opposed pair of chocks 46.
  • a top spacer bar 47 is bolted to the upper face of the two chocks 46 and extends therebetween.
  • the bottom chocks 43 carry uprights 50 on which rest the corresponding top chocks 46.
  • the outer faces of chocks 43 and 46 have grooves 51 which slidably receive the rails 41 of the inverted T-shaped supports 28.
  • the upper ends of these rails carry upstanding pins 52 which project through holes 53 in the top spacer bar 47.
  • Pins 52 have diametric holes 54 through which we insert wedges 55 to hold the roll clusters on the frame sections.
  • FIG. 7 shows a modified means for attaching the top spacer bar 47 to the rails 41.
  • An outwardly projecting bolt 58 is fixed to the upper end of the rail and projects through hole 53 in the top spacer bar.
  • the bolt carries a washer 59.
  • the form of attaching means shown in FIGS. 1 to 6 is rigid, while the springs 60 of the modified form permit the top rolls 32 to yield slightly.
  • the leading and trailing end portions of a workpiece often are cooler than the rest and may be distorted. If the top roll can yield, the end portions can pass with less risk of damaging the mechanism.
  • our invention affords a curved roll rack which is of simple construction, but greatly facilitates assembly, and enables idler rolls to be removed and thereafter replaced always properly positioned.
  • the positioning is automatic, since the idler rolls are of standardized construction, and their support means are not disturbed when they are removed.
  • the idler rolls are supported on standardized frame sections. The latter are supported in part on base members which serve also as housings for driven roll stands.
  • a curved roll-rack which includes arcuate frame sections each having a concave edge, means supporting said frame sections, bottom and top idler rolls, and means on said frame sections supporting said rolls, whereby the rolls define a curved path through which a workpiece may travel,
  • opposed support members of inverted T-shape having cross bars fixed to said pads and uprights which form rails and extend radially from said concave edges toward the center of curvature of the frame sections;
  • chocks being slidably supported on said rails outside the concave edges of said frame sections; and means holding said chocks on said rails;
  • said chocks being removable from said rails without disturbing said members
  • An improvement as defined in claim 2 further comprising bottom and top spacer bars attached to said bottom and top chocks respectively and extending therebetween.
