Definitions

  • Casting roller for casting and / or supporting a casting strand, in particular for a two-roller casting machine
  • the invention relates to a casting roll for casting and / or supporting a casting strand, in particular for a two-roll casting machine, with water cooling, the cooling water supplied in cooling channels in the form of cooling bores or cooling grooves which are distributed over the circumference of the roll and can be removed again, and with a pressure chamber, which adjoins a roller casing and is controllably connected to a pressure medium source.
  • the casting roller is known from DE 33 36 692 C2.
  • This known method and the casting roller for the continuous casting of sheet metal provide, in the (cold) initial state, a negative crowning of the outer peripheral surface, pressure being exerted on an inner region in the hydraulic chamber when the continuous casting operation is initiated, so that the outer peripheral surfaces of both rollers are one take on a real cylindrical shape.
  • the aim is that the metal strip to be cast remains uniformly thick and the rollers remain strictly cylindrical.
  • the invention has for its object to set a profile increase of the cast product of 0.5 to 3%, in particular 1 - 2%, by influencing the profile shape in the casting roll depending on the casting parameters.
  • the roller jacket starting from the sealing elements, has an increasing inner diameter towards the center of the roller and the pressure medium can be applied to the cavity formed to change the profile.
  • the adjusted enlargement of the inner diameter is designed so that the outer roller profile can be adjusted in a targeted manner to generate the required strip profile during casting by means of an internal pressurization of the roller jacket.
  • the inner profile of the roller shell can be adapted to the negative roller profile and that the required profile can be set by means of pressurization in the casting operation.
  • a first alternative embodiment consists in that the roller casing is rotatably arranged on a fixed axis.
  • a second alternative embodiment results from the fact that the roller casing is arranged on a rotatably mounted shaft.
  • a feed ring housing and a discharge ring housing for the cooling water, which flows in axially parallel cooling channels of the roller shell, are provided on the end faces of the roller shell. This ensures simple and low-maintenance cooling water routing of the roll.
  • a further embodiment provides that the hydraulic fluid can be fed into the hydraulic chamber by means of a rotating union.
  • An example of the practical design with a standing axis for this purpose provides that the hydraulic fluid can be fed into the hydraulic chamber by means of a further rotary feed ring housing attached to the inner sleeve part through at least one radial and one axial pressure channel.
  • the pressure medium can be introduced radially or axially via the shaft.
  • the adapted wall thicknesses can be formed over different inner diameters.
  • roller profile of the deformable roller jacket can be adjusted via the liquid pressure as a function of the casting parameters.
  • roller profile of the deformable roller jacket can be adjusted via the liquid pressure as a function of the contact force acting on the roller body.
  • roller profile of the deformable roller jacket can be set via the liquid pressure as a function of the temperature profile of the roller jacket.
  • the pressure of the pressure fluid be set between 50 and 500 bar.
  • FIG. 1 A shows a detail "A" from Fig. 1 and
  • Fig. 2 shows an axial central section through a roller with a rotatably mounted shaft and central guidance of the cooling medium or
  • the casting roll is used for casting and / or supporting a casting strand, in a parallel double arrangement with two largely identical casting rolls for a two-roll casting machine.
  • the casting roll has water cooling, cooling water being fed into the roll body 1 in cooling channels 8 close below the roll surface 1b parallel to the roll axis 1c and discharged again.
  • the cooling channels 8 can e.g. consist of cylindrical bores (Fig. 1).
  • the roller body 1 On a fixed axis 2, which is held in lateral support bearings 3, the rotatably drivable roller body 1 is rotatably supported.
  • the drive of the roller jacket 5 takes place via a drive motor 14 which is supported on the bearing housing of the support bearing 3.
  • the roller body 1 consists of a largely rigid, inner sleeve part 4 which is rotatably mounted on the axis 2 and which is mounted on the axis 2 by means of rotary bearings 4a.
  • the roller body 1 also has a roller jacket 5 which can be deformed by internal pressure to form a cavity 16 above the sealing plane 15a and which has approximately the same length as the inner sleeve part 4.
  • the roller jacket 5 and the inner sleeve part 4 are, for example, firmly connected to one another by a shrink connection and sealed by sealing elements 15.
  • a feed ring housing 6 and a discharge ring housing 7 are provided for the cooling water, which flows through the axially parallel cooling channels 8.
  • the hydraulic fluid is fed through a rotary feeder 9 on a shaft shoulder 4b of the inner sleeve part 4.
  • the rotary feed 9 consists of a further rotary feed ring housing 11, which connects the hydraulic chamber 10 to a fluid pressure source (not shown in more detail) by means of radial pressure channels 12 and an axial pressure channel 13.
  • the outer sleeve 5 has wall thicknesses 5c adapted at least in part lengths to the pressurization, so that a mathematically detectable curve shape, such as, for example, arises for the inner profile 5d of the outer sleeve 5. Parts of a parabola or the like, results.
  • the formation of the adapted wall thicknesses 5c over different inner diameters leads to a stepped or transitional course of the inner profile 5d.
  • the outer roller profile 1 a of the deformable roller jacket 5 can be set via the liquid pressure as a function of the casting parameters of the respective casting strand (for example a steel strip strand).
  • the roller profile 1a of the deformable roller jacket 5 can also be adjusted via the liquid pressure as a function of the contact force which acts on the entire roller body 1.
  • a third setting results from the fact that the roller profile 1a of the deformable roller jacket 5 is adjusted via the liquid pressure as a function of the measured temperature profile of the outer sleeve 5.
  • all dependencies can be considered simultaneously or individually.
  • the pressure of the hydraulic fluid must be set to 50 to 500 bar.
  • a ring torque motor is arranged as the drive motor 14 in order to absorb the tensile force of the cast strand and its weight.
  • the embodiment according to FIG. 2 is based on a rotatable roller body 1 which is rotatably mounted as a shaft 17 in the support bearings 3 and carries the roller shell 5.
  • the roller profile 5d is designed as described for the first embodiment.
  • the cooling channels 8 are connected to a central tube 19 via radial channels 18a, the cooling medium being supplied via a first ring channel 20, distributed into the axial cooling channels 8 via radial channels 18b and collected in the central tube 19 by an axial channel tube section 21 Bores 22 and is discharged again via a second annular channel 23.
  • the axial channel pipe section 21 is sealed on the outer circumference by means of seals 24 and 25 against the central pipe 19.
  • the pressure medium is also introduced centrally through the radial pressure channel 12 and the axial pressure channel 13 into the shaft 17 and via radial channels. channels 23 and axial channel sections 24 inserted into the cavity 16.

Abstract

La présente invention concerne un rouleau de coulée servant à couler et/ou à soutenir une ligne de coulée, notamment pour une machine de coulée à deux rouleaux. Ce rouleau de coulée comprend un système de refroidissement à eau. L'eau de refroidissement admise dans les canaux de refroidissement (8), qui se présentent sous forme d'orifices de refroidissement ou de rainures de refroidissement et sont répartis à la périphérie du rouleau, peut être alimentée et à nouveau évacuée. Ce rouleau de coulée comprend également une chambre de pression (10) qui est adjacente à l'enveloppe du rouleau (5) et qui est connectée de manière réglable à une source de pression. Cette invention permet d'éviter un surhaussement de profil et la formation de coins sur une majeure partie de la longueur du rouleau de coulée, en ce que l'enveloppe du rouleau (5) présente un diamètre interne croissant depuis des éléments d'étanchéification (15) jusqu'au centre du rouleau et en ce que la cavité formée (16) peut être alimentée en pression afin de modifier le profil.
