  • the normal construction for the continuous bar steel, wire and band mills is the two high mill, but the tilting roll pair units shown here may also be constructed for four-high or multi-roll rolling mills.
  • FIG. 13 a different embodiment is shown, wherein the roll pair with stand 55, driving gear 56 and motor 57 is mounted on a bottom plate 5t displaceably mounted in the slide 54 which is rotatably mounted in the fixed turning axis B.
  • the longitudinal displacement of the bottom plate 50 is necessary, partly in order to make the roll pass line C correspond to the angles '4S and partly for the displacement from one track to another.
  • the longitudinal displacement may be effected hydraulically or by a screw 51, gear 52 and motor 53.
  • the complete roll pair unit is supported in the fixed turning axis B and in the support 58, 59 or 60.
  • the roll pair unit may be provided with a frame 6 (as shown inFIGS. 58) instead of with the bottom plate 50 shown in FIG. 13.
  • Stand of rolls for continuous rolling mills comprising a pair of grooved rolls, drive means therefor, said drive means including a drive motor and a motor shelf therefor, a stationary holder, a turning head rotatably mounted in said stationary holder, and inlet guides, said turning head having an opening therein for said inlet guides, said stand of rolls and said drive means as a whole being supported at two points namely partly at said turning head and partly at said drive means.
  • Stand of rolls according to claim 1 characterized in that a frame-work is mounted displaceably on the turning head and that in the frame-work guides are provided 'for the roll mounting for moving the rolls when changing the groove or track.
