Definitions

  • the present invention relates to new improvements in roller cooling and transfer tables as required in rolling mills -for cooling or transferring the metal sheets produced in such mills.
  • Cooling tables on which the metal sheets are cooled by means of rollers have the considerable advantage over those of other types that the sheets are cooled much more uniformly and efficiently and that the points of contact between the cooling table and the hot metal sheets are much smaller.
  • the transfer rollers are preferably made in the form of narrow disks or rollers of a relatively large diameter.” These disks which are mounted on shafts are usually either driven directly, or they are driven indirectly by means of small friction rollers on which the transfer disks are supported.
  • roller cooling tables Another difiicult problem occurring in roller cooling tables consists in the fact that all transfer disks or rollers should have the same peripheral speed in order to avoid harmful relative movements between the transfer disks and the metal sheets, and also in order to insure a trans fer of the sheets in the proper direction along the cooling table.
  • Another known type of construction of a cooling table provides a table surface which is formed of a plurality of parallel and independently acting groups of rollers of a relatively small diameter which are driven individually or in groups by means of small friction rollers, and each pair of which is mounted on "acommon shaft.
  • rollers will deviate from their vertical position, a relative movement between the peripheral surfaces of the rollers and the metal sheets to be transferred will result, and the individual units each consisting of a pair of rollers on one shaft will no longer be in balance.
  • Another object of the invention consists in subdividing the long directly driven shafts into a plurality of shaft portions of a number and length depending upon the width of the cooling table, and in interconnecting the adjacent shaft portions by means of expansion couplings.
  • a further object of the invention consists in providing a cooling table which is designed so as to avoid any distortion of the shafts carrying the transfer disks by enclosing these shafts within tubular members which have an inner diameter larger than the diameter of the shafts.
  • the individual tubular members are preferably made of a length which is slightly smaller than the inner width between the hubs of two adjacent disks and so that their ends are centered on the shafts also has the disadvantage
  • Fig. shows a partial cross section similar to Fig. 2 but on an enlarged scale; While Fig. 4 shows a cross section of the cooling table according to Figs. 1 to 3, taken in the direction of transfer of the metal sheets.
  • each full. shaftlength of the cooling-table according to the invention is divided into two separate sections of substantially equal length, each of which is driven by a separate motor M at the respective outer end thereof.
  • the total length of each shaft section forming. one-half of the width of the cooling table preferably amounts to about 55. ft.
  • each shaft section is subdivided into three parts or sections W W and-W which are connected to each other by means-of'expansion couplings K so as to permit each part of the, shaft to expandfreely. 7
  • Each of these directly-driven composite shafts W1 to W carries aplurality of transfer disks, for example, T to T and is rotatably mounted without any axial bearingsbut by means of small supporting rollers S which; are freely rotatable within bearing brackets B and sup: port transferdisks T to T As illustrated particularly in Figs.
  • each bearingbracketB carries a, pair of such supporting rollers S, and each pair supportsonetransfer disk T at two angularly spaced points thereof, thereby also supporting andcentering the composite shaft W to W
  • each bearingbracketB carries a, pair of such supporting rollers S, and each pair supportsonetransfer disk T at two angularly spaced points thereof, thereby also supporting andcentering the composite shaft W to W
  • two alternatedisks T on each shaft portion W are supported by twosets of rollers S, The-supporting rollers S are thus spacedat a considerable distance from the hot metal sheets;
  • tubular members R' are: slidably mounted on the projecting ends of shaft portions;
  • afpaintlike coating consisting of a material h ch. it l s n d rad at o sep lent:
  • the different shaft: portions. may; alsof-be coatedwith such material. Such coating will have the eifect that the shafts will be heated very uniformly and that any uneven distortion thereof will be absolutely prevented.
  • The'diiferent means as described for protecting the shafts from distortion will insure that the transfer surface formed by the large number of transfer disks in a staggered relation to each other will always. be within a perfectly level plane regardless of the speed of trans'" I fer of the metal sheets.
  • the, design of. a cooling, table according to, the present invention completely and reliably overcomes the various difficulties incurred in all previous cooling tables by the heat radiated from the. metal sheets; conveyed. thereon and it also safely prevents the occurrence of any relative movements between the transfer disks and the metal sheets which are to be transferred thereby.
  • coolingbed for cooling and conveying hot metal sheetsfrom a: rolling mill comprising a plurality of parallel shafts, a driving means directly connected to.
  • bearing means for, rotatively supporting said rollers.
