Definitions

  • a double walled tubular assemblage for cooling hot wire including coaxial inner and outer tubes with a a coolant under pressure being introduced into the space between the tubes and a wire to be cooled is passed forwardly through the inner tube.
  • the inner tube is provided with nozzles which point in a forward direction and are angularly and longitudinally spaced with respect to the axis of the inner tube.
  • a plurality of coaxial funnels are mounted within the inner tube and an aperture in each funnel is located around a nozzle whereby the coolant can be ejected under pressure through the nozzles to pass forwardly through the apertures for impinging upon all sides of the Wire.
  • the present invention relates to an improved double walled tubular assemblage for cooling elongate material such as hot wire. While the invention is particularly useful for cooling rolled material such as rolled wire, rod, or tube, it is of course of broader application.
  • roller material such as wire
  • the structure of the material is important such as for example, the rate of cooling of the rolled wire between the last rolling stage and the final reeling stage has a considerable influence on scale formation. Both the thickness and composition of the scale is afilected and the structure of the rolled material per se is also influenced by the cooling.
  • One known apparatus employed for cooling wire or other cross sections, after the final rolling stage, includes a double walled water cooling tube with the inner wall thereof being provided with a plurality of holes through which water passes onto the material to be cooled.
  • the material may be passed through several such tubes for improving the cooling effect.
  • the apparatus cannot be utilized for giving an effective cooling of thicker material such as for example wire having a diameter of from to mm.
  • the wire has a tendency to bear against the holes on the lower side of the inner tube thereby obstructing the passage of water.
  • the wire is cooled more on the upper side than on the lower side which means that the wire bends and is thus difilcult to guide properly through the cooling tube.
  • a salient object of the present invention is to provide a cooling tube assemblage which prevents or at least reduces the above mentioned disadvantages.
  • the present invention comprises a tubular assemblage for cooling elongate material such as hot wire by passing a wire in a forward direction axially through the assemblage, with such assemblage including coaxial inner and outer tubes, means for passing a coolant under pressure into the space between the tubes, nozzles sealed in the inner tube Which point forwardly and are spaced angularly and longitudinally with respect to the axis, a plurality of coaxial funnels mounted within the inner tube and an aperture in each funner located around a nozzle so that the coolant can be ejected under pressure through the nozzles to pass forwardly through the apertures in the funnels for imping upon all sides of the material to be cooled.
  • the nozzles are equal-angularly spaced around the axis of the inner tube at intervals of between 60 and 120.
  • the nozzles are all directed forwardly and the axis of each nozzle may lie either in an axial plane or may be inclined thereto at an angle of up to 20.
  • the center of the coolant jet issuing from each nozzle preferably lies at 60 with respect to the axis of the inner tube and in any event is less than
  • the nozzles are inclined forwardly with respect to the axis of the cooling assemblage in such a fashion as to produce low-trajectory jets lying at an angle of less than 90 to the axis with each jet preferably lying in an axial plane.
  • the plane containing the jet may be positioned at an angle of up to 20 with respect to an axial plane and inclining the nozzles forwardly at such an angle assures that a greater leng'.h of material to be cooled receives coolant from each nozzle.
  • the double walled tubular assemblage denoted generally T comprises an outer tube 1 provided with an inlet 2 for a suitable coolant and an inner tube 3 coaxial with and spaced from the outer tube 1 and through which wire to be cooled passes.
  • a series of substantially frusto-conical coaxial funnels 4 are located within the inner tube 3 and smaller ends 4a of the funnels all point in a forward direction as indicated by arrow A which of course is the direction in which the material to be cooled is passed through the tube 3.
  • each funnel 4 in proximity to its larger end 4b is provided with a radial aperture 5 and the funnels are fixed within the inner tube 3 in such a manner that adjacent apertures are displaced around the axis of the tube by an angle of 90 which means that by the time the material has passed four apertures it has received coolant on four sides, as will later be described.
  • Short tubes 6 are sealed through the inner tube 3 and sleeves 7 holding nozzles 8 are seated in the tubes 6.
  • the axis of each nozzle 8 is directed forwardly through an aperture 5. More specifically the axis of each nozzle 8 is inclined to the axis of the tube at an angle of less than 90 and preferably at an angle of 60. By virture thereof, any tendency of the coolant to build up is prevented.
  • the notation forward direction is intended to include all directions having a component in the axial direction.
  • each nozzle 8 and the coolant jet issuing therefrom lies in an axial plane of the tube 3.
  • the nozzles 8 also lie in the shadow of the funnels so that the nozzles cannot be touched or contacted by the material passingthrough the inner tube 3.
  • an aperture cap 9 At one end of the tubular assemblage T there is provided an aperture cap 9 and at the opposite end a flange 10.
  • a guide ring 11 is located between the flange 10 and the larger end 4B of the first funnel 4. It will also be seen that the flange 10 is equipped with an entry funnel 12 for the material to be cooled.
  • the coolant is applied to several sides of the material and not merely to one side as has been true in the known apparatus.
  • the size of the smaller or outlet ends of the funnels 4 can be adapted to any required flow rate for the coolant.
  • the same wire when cooled in a double walled tubular assemblage made in accordance with this invention has a surface temperature of 740 C. upon leaving the assemblage and 750 C. upon arriving at the wire cutter.
  • the applicants tubular assemblage had a length of four meters and was provided with 22 nozzles producing lowtrajectory jets and the opening in each nozzle was 8 mm.
  • the nozzles were spaced along the length of the tube and the angular displacement between jets was 90 with the axis of each nozzle intersecting the axis of the tube in the forward direction at 60.
  • the nozzles were supplied with water at a pressure of 10 atmospheres absolute and the water consumption was 160 m. /hour.
  • a tubular assemblage for cooling elongate material such as hot wire by passing a wire in a forward direction axially through the tubular assemblage comprising coaxial inner and outer tubes, means for introducing a coolant under pressure into the space between the inner and outer tubes, nozzles sealed in said inner tube, said nozzles pointing in a forward direction and spaced both angularly and longitudinally with respect to the axis of the inner tube, and a plurality of coaxial funnels mounted within said inner tube and through which the material passes, each funnel having an aperture located around a nozzle whereby the coolant can be ejected under pressure through the nozzles to pass forwardly through the apertures to impinge upon all sides of the material to be cooled.
  • each nozzle is forwardly directed at an angle of between 60 and 90 with respect to the axis of the inner tube.
