Definitions

  • the diameter of the flanges is advantageously greater than the maximum transverse dimension of the rolled element and also depends on the degree of flexibility of the band element 16, in addition to other factors listed below.
  • a completely closed chamber is formed between one stand and another for the cooling and lubricating liquid, so that any possibility of contact with the external air and danger of oxidation of the element being rolled is eliminated.
  • this pressure may be considerably increased precisely by the presence of a closed chamber, and may thus practically equal that inside the stands for the entire rolling train ifa device such as that described is disposed between all stands present.
  • the greater pressure which is constant along the entire path. enables a better product to be obtained from all aspects, and mainly with regard to its surface appearance, which is known to depend mainly on the cooling conditions to which it is subjected during its formation.
  • the device according to the invention is moreover easily assembled, it being necessary only to fix the flanges l8 and introduce the band element 16 into the groove 17 until it makes one complete turn.
  • gripping means may be disposed on the end of the band element 16, for example a ring may be welded to it in a plane orthogonal to that of the element.
  • a device for conveying the cooling and lubricating fluid in a multi-stand rolling mill for the production of metal bars and wire in general comprising support means fixable to the facing walls of two adjacent rolling stands and a band element slideable in said support means and defining a tank for containing the cooling and lubricating liquid
  • the said support means each comprises at least one groove extending along a substantially cylindrical surface with its axis substantially parallel to the direction of movement of the element being rolled, and an aperture substantially tangential to said groove for the introduction of said band element into said support means, said band element being slideable in said groove to the extent of defining a closed space entirely about the element being rolled between one stand and the next, the radius of curvature of said grooves being substantially greater than one half the maximum transverse dimension of the element being rolled.
  • said support means consist of two flange elements each having a substantially flat annular section and a rim projecting from said substantially flat annular section, said flange elements having different diameters and being mounted with their flat annular sections in mating engagement and the rims extending opposite to one another, the radial extent of said flat annular section of one of said flange elements being smaller than the radial extent of the flat annular section of the other of said flange elements, thereby to define said band receiving groove between said flat annular section having the smaller radial extent and the rim of the other flange element.
  • a device as claimed in claim 2 wherein said projecting rim of the flange element having the greater diameter has a notch having a height at least equal to that of said groove and extending tangentially to said groove for the introduction of said band element into said groove.
