Definitions

  • the invention relates to an internally cooled support and / or transport roller according to the preamble of patent claim 1.
  • Internally cooled rolls for supporting and / or transporting hot metal bodies, in particular steel strands produced in continuous casting processes, are known (cf. DE-A-2 408 769 and the generic DE-A-1 583 619). They usually consist of a core, in the surface of which one or more channels are incorporated. The channels merge into radial bores which open into axially directed bores arranged in the bearing journals. The latter are used for coolant supply and removal.
  • the core of the roller is surrounded by a sleeve which is shrunk onto the core and closes the cooling channel or the cooling channels of the core to the outside.
  • the roller When the roller is pressed onto the strand, which is hot up to 1200 ° C, the roller is subjected to considerable mechanical and thermal loads, which lead to deflection and warping. With regard to the sleeve, it can be noted that it partially detaches from the core under the loads mentioned during operation and then the cooling medium is no longer positively guided. The result is reduced cooling at the highly stressed line of contact with the strand. In addition, the mechanical stability is affected by this process.
  • the invention has for its object to eliminate the disadvantages mentioned and to provide a roller which has an improved bending stiffness, is thermally stable, also in relation to the cooling effect to be exerted on the strand, and to specify a method for producing such a roller.
  • Thermally stable is also to be understood as the case that the operability of the roller is not impaired in the event of occasionally increased one-sided heat application.
  • a method according to the invention for producing such a roller includes claim 11.
  • a roller 1 is provided with a helical coolant channel 2, which is connected to concentric bores 3 arranged in the bearing journal 4 as coolant inflow or outflow via radial bores 5.
  • the individual turns of the coolant channel 2 are separated from one another by the web 6, so that there is a positive guide for the cooling medium in the entire roller 1.
  • the forced guidance is achieved, as shown in FIGS. 2 to 6, by a coolant-tight connection of the webs 6 of the core 7 with a sleeve 8 applied to the core 7.
  • the coolant-tight connection and the fixing of the sleeve 8 relative to the core 7 can be achieved in that the web 6 is trapezoidal thread-shaped and engages in a corresponding recess 9 on the inner surface 10 of the sleeve 8.
  • a groove 12 is incorporated in the end face 11 of the web 6, into which a seal 13 of circular cross section is inserted.
  • the sleeve 8 is screwed onto the core 7, the pitch of the thread being self-locking. At the ends, the sleeve 8 is expediently welded to the core 7.
  • the end face 11 of the web 6 itself is provided with a thread which is connected to a corresponding thread in the inner lateral surface 10 of the sleeve 8.
  • the end face 11 of the web 6 is permanently and tightly connected to the inner lateral surface 10 of the sleeve 8 by a pressure welding.
  • Pressure welding is understood to mean resistance welding, such as spot welding or roll seam welding. It is of course also possible to cover the coolant channels 2 with appropriate tapes and to weld the tape edges 14 according to FIG. 5, including the end face 11 of the webs 6.
  • the band forming the sleeve 8 in the welded state for covering the coolant channels 2 is obtained from a tube with the dimensions of the desired sleeve, in which the tube is separated or strips of material from the tube wall in accordance with the course of the webs are cut out in such a way that the remaining cut edges slightly cover the webs 6, leaving a gap for the weld seam which connects the cut edges 14 to the web 6.
  • the coolant channel 2 in such a way that it has a large cross-section with a small cross-sectional area and the side the cross-sectional area with the greatest length extension is formed by the inner lateral surface 10 of the sleeve 8, for example by rectangular design of the cross-sectional area of the coolant channel 2 (FIG. 6) or, as shown in FIG. 7, by a trapezoidal cross section.
  • the inner lateral surface 10 of the sleeve 8 a notch-effective, stress-reducing and surface-increasing shape near the connection points with the web 6, for example, as shown in FIGS. 2 to 5 and 7, by means of semicircular recesses 19.
  • This shape also improves the cooling effect.
  • the ratio of the radius r of the core to the radius of the radius a reduced by the coolant channel 2 is 1: 0.9.
  • This method according to the invention is of course not limited to the example described for the production of an internally cooled roll. It can be used wherever weldable metal parts are only to be connected in parts of their surface, for example in the construction of apparatus or containers. Sub-areas of their surface are understood to mean cases in which flat bodies overlap with their larger surface portion, but only touch in sub-areas, so that inaccessible welding areas arise.
  • a roller is obtained which, for a given outer diameter, has the largest possible core diameter with the smallest sleeve thickness. It therefore has a large section modulus.
  • the thermal load on the roll is reduced to a small part, namely the jacket.
  • the large section modulus of the roller, including the sleeve ensures that the roller remains free of distortion even if the sleeve surface is heated on one side for a long time.
  • the effective cooling system supports the roller in its functions with a low wall thickness of the sleeve, a controlled water flow, a high speed of the cooling medium and a large cooling surface.
