Definitions

  • ABSTRACT An apparatus for changing work rolls in a rolling mill.
  • the apparatus includes a carriage assembly mounted on tracks for movement into and out of a roll housing through a housing window.
  • the carriage assembly is adapted to receive and carry a roll package made up of a plurality of work rolls rotatably supported between bearing chocks.
  • the tracks are so arranged that upon movement of the carriage assembly and roll package carried thereon into the housing. the carriage assembly is gradually lowered to transfer the roll package onto the housing, with the result that the roll package is solely sup ported by the housing when operatively contained therein.
  • This invention relates generally to rolling mills and more particularly to an improved apparatus for changing work rolls.
  • a further and more particular object of the present invention is to support the roll package on a carriage assembly which is movable througha housing window along a system of tracks between an inoperative position exterior of the housing an operative position at which the roll package is contained within and supported solely by the housing, with the design and arrangement of the carriage being such as to require substantially no vertical enlargement of the housing window beyond that required to accept the roll package.
  • Another object of the present invention is to reduce the number of interfaces between the housing and the roll package contained therein. This is accomplished by arranging the track system in a manner such that upon entering the housing, the carriage is lowered until the roll package is deposited directly on the housing.
  • Another object of the present invention is to provide a novel and improved means for laterally displacing both the carriage assembly and the housing relative to the mill pass line.
  • FIG. 1 is a front elevation with parts broken away of a roll housing and roll changing apparatus embodying the concepts of the present invention
  • FIG. 2 is a partial vertical section on an enlarged scale through the roll housing and roll changing apparatus shown in FIG. 1;
  • FIG. 3 is a perspective view of the apparatus shown in FIG. I with the roll package and carriage assembly in the inoperative position exterior of the roll housing;
  • FIG. 4 is a sectional view taken along line 44 of FIG. 1 with the roll package removed for the purpose of better illus trating the carriage and underlying track system;
  • FIG. 5 is an end view of the carriage assembly taken along line 5-5 of FIG. 4.
  • FIG. 6 is a sectional view taken along line 6-6 of FIG. 5'
  • FIG. 7 is a sectional view through the carriage assembly showing the lower roll chocks of the roll package supported thereon;
  • FIG. 8 is a view similar to FIG. 7 afler the carriage assembly has been moved to the operative position, with the lower roll chocks supported directly on the housing.
  • FIGS. I and 2 there is shown a roll housing 10 mounted on underlying rails 12 for movement in a direction transverse to the mill pass line.
  • the roll housing is adapted to contain a roll package generally indicated at 14 (See FIG. 3), the latter including a pair of work rolls 16a and 16b each respectively journalled for rotation between roll chocks Ifla at 18b.
  • the roll package i4 is shown in its operative position contained within the housing in FIGS. I and 2, and in its inoperative position withdrawn from the housing in FIG. 3.
  • the roll changing apparatus of the present invention is comprised basically of a carriage assembly 20 (FIG. 3) which in the embodiment herein disclosed, is movably mounted on a track system made up of first and second track members 22 and 24.
  • the first track members 22 are supported exterior of the housing on raised fixed abutments 26.
  • the top surfaces of the first track members are preferably located at approximately mill floor level, shown in FIGS. 1 and 4 by a removable l'loor plate 28.
  • the second track members 24 are attached to and supported by the roll housing 10.
  • the ends of the second track members 24 preferably extend through the using windows 30a and 30b located at either side of the housing.
  • the carriage assembly 20 is comprised of two spaced parallel side members 32a and 32b joined at one end by a transverse front member 34 and at the other end by a transverse rear member 36.
  • the front transverse member 34 is provided with a pair of integral depending legs 38 which support axles 40 on which are rotatably mounted front wheel members 42.
  • the front wheel members are arranged to run along the first track members 22.
  • the rear member 36 likewise supports axles 44 on which are rotatably mounted rear wheel members 46 suitably spaced and arranged to run along the second track members 24.
  • the front transverse member 34 of carriage assembly 20 is further provided with an additional leg member 48 depending centrally between the leg member 38 supporting the front wheel members 42.
  • the piston rod 50 of a double acting cylinder 52 (preferably hydraulically actuated) is pivotally connected as at 54 to the leg member 48.
  • the cylinder is in turn pltotall ⁇ connected as at 56 to a stationary support member 58.
  • Movement of the roll package I4 from the inoperative position shown in FIG. 3 to the operative position shown in FIG. I is accomplished by simply extending piston rod 50.
  • This causes the carriage assembly 20 with the roll package I4 supported thereon to be moved along the track system comprised of first and second track members 22 and 24 through housing window 30a in a direction transverse to the mill pass line.
  • the piston rod 50 approaches the end of its stroke, the front wheel members 42 descend downwardly sloping end portions 64 on the first track members 22.
  • the rear wheel members 46 descend identically sloped portions 66 on the ends of the second track members 24.
  • the combined effeet is to lower the carriage assembly 20 relative to the housing structure 10, thereby causing (See FIG.
  • the roll housing is additionally provided with a pair of laterally extending connecting pins 70.
  • the pins are suitably spaced and arranged to extend through apertures 72 in the front transverse member 34 of carriage assembly when the latter is in the position shown in FIG. 1.
  • Locking wedges 74 are then inserted transversally through slots in the pins 70 to securely fasten carriage assembly 20 to the housing 10. Thereafter, further extension and or retraction of piston rod 50 results in a corresponding combined movement of both the carriage assembly 20 and housing 10 along tracks 12 in a direction transverse to the mill pass line.
  • the carriage assembly 20 is gradually lowered as the front and rear wheels 42 and 46 roll over the inclined end portions 64 and 66 of the first and second track members 22 and 24. This causes the lower bearing surface 62 on the chocks 18b to come into direct contact with the underlying bearing surfaces 68 of the housing.
  • this offers the further advantage of reducing the number of interfaces between the roll package and the housing to an absolute minimum of one with a further corresponding increase in housing rigidity over that offered by the prior art constructions.
  • the locking wedges 74 are next employed to lock the car riage assembly 20 to the laterally extending pins 70 on the housing.
  • the piston rod 50 of cylinder 52 is extended further to laterally displace the housing 10 relative to the pass line along rails 12.
  • This particular arrangement is of course advantageous in that it allows one cylinder 52 to serve two functions, namely the lateral displacement of the carriage assembly 20 relative to the housing 10 and the lateral displacement of the entire housing relative to the mill pass line.
  • a spare roll package might be mounted on a spare carriage and the roll parting completely pre-set at a remote location while the rolling operation is in progress.
  • the spare assembly would be carried to the housing and quickly substituted in the manner just described for the assembly being removed from the housing. Under these conditions, the carriage would serve the additional function of providing a fixture for carrying roll packages between the housing and the remote set-up location.
  • Apparatus for moving a roll package between a first position exterior of a roll housing and a second position contained within the housing comprising: track means extending between said first and second positions; carriage means movable along said track means between said positions, said carriage means being adapted to receive andsupport the roll package at said first position, said track means including means cooperating with said carriage means during movement of the latter into said second position to transfer the roll package from said carriage means directly onto the housing.
  • said track means is comprised of first and second parallel track members, said first track members being located at one level at said first position, and said second track members being carried by said housing at said second position at a level above that of said first track members.
  • said housing includes bearing means between said second track members, the vertical displacement of said carriage means being such that the roll package is lowered onto said bearing means when said carriage means is moved along said track means from said first position to said second position.
  • the apparatus as claimed in claim 5 further characterized by said housing being movably mounted on third track members. said third track members being parallel to said first and second track members.
  • apparatus for moving a roll package between said operative and inoperative positions comprising in combination: first and second longitudinal track members, said first track members being separate from said housing at one level underlying said inoperative position, said second track members being mounted on said housing at a level above that of said first track members; carriage means mounted on said track members for movement between said operative and in operative positions, said carriage means forming a bed adapted to receive and carry the roll package; said carriage means being further provided with wheel members arranged at two levels to roll along said first and second track members respectively; operating means connected to said carriage means for moving said carriage means between said operative and inoperative positions, said first and second track members being further provided with inclined end sections which when contacted by said wheel members, result in the carriage means being displaced vertically relative to the housing, the vertical displacement of said carriage means being such that the roll package is lowered onto
