Definitions

  • My invention relates more particularly to .that class of rolling mills for the enlongation of material in which the working rolls are supported.
  • the diameter of the rolls should be as small as possible, because experience has shown that rolls of small diameter produce great elongation ofthe material to be rolled. These rolls of small diameter, however, show, under the counter-pressure of the material to-be rolled, a conslderable sagging or deflection and must therefore be supported.
  • the working length is limited by the length of the rails and, moreover, elaborate arrangements for supporting and guiding the rails become necessary.
  • My invention has for its object to eliminate the defects of these known arrangements and to provide for an effective cooling of the working. rolls.
  • Figure is a vertical longitudinal section of a two-high rollin m'll with five difierent sizes of passes, and Iig. 2 is a front view of the same mill in which one of the frames is omitted.
  • F1g. 3 is asimilarview of a rolling mill with supportmg rings on both sides of the worklng roll.
  • Figs. 4 and 5 are views of a three-high rolllng mill; Fig. 4* is a diagrammatic new indlcatlng the eccentric mounting of the rings b.
  • F 1gs. 6 and 7 are views showing details and Fig. 8 shows a rolling mill with a coolm arrangement
  • a I eferring to the drawings a working roll a of small diameter is supported at the working portionsby rings 1), which by the insertion of balls 0 or rollers, revolve freely on fixed axles d held byZthe frame e.
  • the supporting rings 6 are of a very large diameter; in relation to the diameter of the working rolls a.
  • the rolls and rings can revolvefreely, whereby a great savmg in I rso power is effected.
  • the supporting rings 1n may be arranged laterally in such a position as to receive the pressure on the working roll and in a man-, ner similarto that already known in connec- .tion' with supporting rolls.
  • the tendency of the working rolls to creep up theface of the supporting rings is revented.
  • the rolling mill always works in one -directlon only, one "supporting ring arranged laterally in such a position .as to receive the pressure on the roll or oneset of supporting rings for each workinglroll arranged this manner is suificient.
  • the roll- 1ng m1ll works alternately indifferent directlons, supporting rings can be arranged onboth sides of the working froll'as shown- 'in Figs. 3and 4.
  • fashioned parts may be rolled.
  • the normally fixed axles d of the supporting rings may be arranged in the housings in an adjustable manner.
  • Figs. 6 and 7 represent an example of such an adjusting arrangement.
  • the axle d is laterally adjustable in its bearing part 7 by means of screws g.
  • the bearing part f which is guided at k may further assume a different position in height by a lateral shifting of 'the wedge piece 1.
  • Fig. 8 shows the cooling arrangement in which the cooling liquid is fed through pipe k intoan annular'space Z in the bearing m and then enters, through one or several holes in the neck, the From the bearing hand end of the liquid passes to the interior of the roll through the hole 1 and travels lengthwise of the roll through passage n to the opposite end thereof at whichv point it passes out through hole l to the bearing at this end and is led thence through pi ing Z to the bearing of the" roll above. ere it enters through hole I the interior passage n of this roll and travels in opposite direction therethrough to the other end' of this roll of one roll, e. g. the right where hole 1 communicates with the bearing above that of the lower roll at which the liquid enters through pipe is.
  • the liquid may be.
  • Two or more rolls may be cooled in the manner described.
  • a rolling .mill a plurality of stepped working rolls having a series of passes of diflerent dimensions, and cooperating supporting collars on said rolls arranged between the passes, together with supporting rings rotating on fixed axes parallel to those ofthe rolls and bearing agalnst'the top and bottom working rolls, for the purpose described.
  • a working roll having a supporting collar arranged between adjacent passes, and a cooperating collar on the adjacent intermediate roll, together with a supporting ring bearing against said working roll'and rotating on a fixed axis parallel to-that of the working roll.
