Definitions

  • This invention relates to a roll suitable for transferring heat between the roll and the material in contact with it.
  • a particular, but not sole, application of the invention is to a roll suitable for use in a two-roll strip caster.
  • a strip caster usually consists of a pair of rolls, arranged side-by-side with their axes of rotation horizontal, and which are spaced apart to provide a gap between them.
  • the ends of the roll barrels can be provided with dams to form a space above the roll gap into which molten metal is poured.
  • the rolls are usually liquid cooled to absorb heat from the molten metal which come into contact with them and form solidified skins which thicken as the rolls rotate. As the rolls are rotated they force the solidified skins of metal together and through the gap between the rolls to form a continuous metal strip.
  • An object of the present invention is to provide an improved roll construction which permits greater throughput together with a stable roll design, which can readily be refurbished at the end of its useful life.
  • a roll suitable for use in a two-roll caster comprises a rotatable arbor; an annular sleeve shrunk onto the arbor to serve as the roll barrel, said sleeve having at least one internal passage for the flow of liquid coolant there along, and wherein in use, liquid coolant flowing along the passage(s) serves to form a theraal barrier in the sleeve located between the outer peripheral surface of the sleeve and the interface between the sleeve and the arbor; and ducts in the arbor in communication with the internal passage(s) in the sleeve to permit the liquid coolant to flow to and from the passage(s) and the exterior of the roll.
  • the sleeve may be provided with a plurality of internal passages each extending parallel to the longitudinal axis of the arbor. These passages may be formed by boring holes along the axis of the sleeve. Alternatively, there may be a plurality of internal passages extending around the sleeve and coaxial with the periphery thereof.
  • the part of the roll which contacts the molten material In order to absorb as much heat as possible from the molten material, it is necessary for the part of the roll which contacts the molten material to be of a high conductivity metal, such as steel, copper, or any of their alloys.
  • the surface of the high conductivity metal may be covered with a protective surface layer, which for example could be a stainless steel with good thermal fatigue properties or a nickel or nickel/chrome layer or a metal matrix composite layer such as tungsten carbide/cobalt alloy or chrome carbide/nickel-chrome composite.
  • a protective surface layer which for example could be a stainless steel with good thermal fatigue properties or a nickel or nickel/chrome layer or a metal matrix composite layer such as tungsten carbide/cobalt alloy or chrome carbide/nickel-chrome composite.
  • the sleeve may be removed from the arbor by externally heating to expand the sleeve whilst omitting all sleeve cooling.
  • the sleeve could then be refurbished prior to re-assembly.
  • the sleeve serves as the roll barrel and, since an external force can be exerted upon it, there has to be a shrink fit between the sleeve and the arbor to prevent it rotating around the arbor.
  • the temperature of the sleeve relative to that of the arbor is not such that will cause differential expansion between the arbor and the sleeve so as to remove the interface joint between them.
  • a thermal barrier to be located between the outer surface of the sleeve and the interface between sleeve and the arbor, a limited minimum amount of the heat applied to the outer surface of the sleeve penetrates to the interface between the sleeve and the arbor.
  • the liquid cooled sleeve efficiently removes heat from the outer surface of the sleeve thereby permitting rapid cooling of the material which is in contact with it.
  • the interference fit between the sleeve and the arbor provides a tensile stress in the sleeve which helps to negate the thermally induced compressive stresses.
  • Figure 1 is a view, partly in section, of a cooling roll in accordance with the present invention
  • Figure 2 shows to an enlarged scale the part of the roll within the broken lines of Figure 1;
  • FIG. 3 shows a sectional view of an alternative cooling roll also in accordance with the invention.
  • a roll suitable for use in a metal caster comprises an elongate arbor 1 having cylindrical portions 3 adjacent each end for receiving bearing assemblies (not shown) . Substantially at the centre of the arbor there is a cylindrical surface 5 on to which an annular copper-alloy sleeve 7 is shrunk. At one end of the surface 5 there is an annular rib 9 which is integral with the arbor. An annular recess 10 is formed in the adjacent end wall 11 of the sleeve and a plurality of fitted bolts (not shown) extend through the rib into the sleeve 11 to provide additional securement for the sleeve on to the arbor. The recess 10 is closed off by an annular ring 12 which is secured to the rib 9 by a plurality of bolts 13.
  • An axial bore 15 extends into the arbor 1 from the non-drive end 16.
  • a pair of annular channels 17A, 17B are formed in the surface 5 of the arbor beneath the sleeve 7.
  • a plurality of radial bores 19 extend from the channel 17A to the bore 15 and, similarly, a plurality of radial bores 21 extend from the channel 17B to the bore 15.
  • the two channels 22, 23 are connected by a multiplicity of passages 25 which extend between them in a direction substantially parallel to the longitudinal axis of the arbor 1.
  • the passages 25 are spaced apart around the entire annular sleeve.
  • the channel 22 is connected to the channel 17B by a bore 27 within the sleeve and, similarly, the channel 23 is connected to the channel 17A by an internal bore 28.
  • the channels 22, 23 are closed off by cover plates 29 which may be of the same material as the sleeve 7 and fixed in position by any convenient means such as welding along lines 30.
  • a tube 34 with a central enlarged outer diameter and seal 35 is located within bore 15 and provides a barrier between two annular areas 17A and 17B one of which communicates with radial bores 19 and the other communicates with radial bores 21 for the passage of outgoing and incoming liquid coolant.
  • liquid coolant usually water
  • water is passed along the space between the tube 34 the bore 15 and into each of the bores 19 where it flows to the channel 17A at the interface between the sleeve and the arbor.
  • the water then flows along the bore 28 to the channel 23 extending around the adjacent end face of the sleeve.
  • the water flows through the multiplicity of bores 25 to the channel 22 in the end face 11 of the sleeve.
  • the water flowing through the passageways 25 cools the adjacent parts of the sleeve and, consequently, a cooled zone extends around the sleeve in the vicinity of the passageways.
  • This cooled zone serves as a barrier which reduces the flow of heat from the outer surface of the sleeve to the interface between the sleeve and the arbor, thus preventing the temperature of the sleeve in the vicinity of the interface with the arbor from rising to a level where the shrink fit interface between the sleeve and the arbor is destroyed.
  • the cooled zone serves to cool the outer surface of the sleeve thereby causing metal to solidify in contact with the surface.
  • the coolant may be made to flow in the reverse route to that described previously.
  • a rotary coupling
  • An annular seal 33 is located at each end of and between the sleeve and the arbor to prevent leakage of coolant from between the arbor and the sleeve. These seals can be fitted after assembly of the sleeve which will aid maintenance in the event of failure as well as negate the requirement to assemble the seals prior to the shrink fitting of the sleeve 7 on to the arbor 1.
  • the sleeve can have a hard facing layer 31 on its outer periphery.
  • This layer may comprise of chrome on nickel or stainless steel or a metal matrix composite such as tungsten carbide/cobalt alloy or chrome carbide/nickel-chrome composite.
  • the barrel ends of sleeve 7 also can have similar hard facing layer 32.
  • Figure 3 shows sleeve 35 formed by welding or otherwise suitably joining together two separate sleeves 35a, 35b at joints 36. Coolant enters the arbor 38 along a hole 39 and then passes via radial bores 40 to a slot 41.
  • the cooling water passes through a series of radial holes 42 to circumferential grooves 43 where it splits into two directions to pass circumferentially around the sleeve until the two flows unite to exit by a second series of radial holes 44.
  • the cooling water passes from radial holes 44 to a second slot 45 which is connected to the outlet hole 46 in the arbor 38 by radial bores 47.
  • Figure 3 also shows an alternative method of providing the rib 9 shown in Figures 1 and 2.
  • the rib is formed by fixing a disc 48 to the arbor 38 with bolts 49.
