Definitions

  • the invention relates to a / 4-Rollen- / 6-Rollen / 18-HS roll rolling mill in cassette construction.
  • Previously known 4-high, 6-high, 18 HS rolling stands in cassette construction, have no possibility of combining different operating modes, such as CVC plus® 4-High or 6-high and CVC plus® 18 HS.
  • An essential requirement of a combined roll stand is that it is possible to change between the two operating modes during a conventional roll change without having to carry out remodeling actions on the stand.
  • the object of the invention is therefore to be able to roll with different operating modes and roll diameters in a roll stand while minimizing the changeover times and accordingly to increase the annual production.
  • the piston rod of the upper cylinder bending cylinder and the lower roller piston rod are made in one piece.
  • the supply of hydraulic for the piston as well as the ring sides is effected by the piston rod
  • the combined rolling stand is to be used both as a reduction stand and as a temper rolling mill, as well as for normal steel, high-strength steels, stainless steels and non-ferrous metals.
  • the work roll sets of the 4-high / 6-high stand can be exchanged for the intermediate roll sets in cassette construction (including side support rolls) and the work rolls of the 18 HS stand.
  • the change position of the work roll sets in the 4-high / 6-high stand is identical to the change position of the intermediate roll sets in the 18 HS stand.
  • the same Axialverschiebezylinder be used as well as bending cylinder.
  • large strokes are required for the bending cylinders, with limited space available at minimum roll diameters in the 4-roll / 6-roll mill.
  • the cylinder bodies are fixedly mounted in Mae West blocks and the bending force is transmitted via the piston rods and a guided intermediate piece to the bending journals of the roller mounting pieces.
  • the bending concept according to the invention consists in that the piston is firmly connected to the piston rod with the Mae West Block, that is, the cylinder body is displaced.
  • the movable cylinder bodies are pushed upwards or downwards.
  • the cylinder bodies are designed so that they comprise the bending pins on the chocks of the rollers and thus the bending force directly on the bending pins of the
  • Roll chocks is transferred.
  • the piston rod of the bending cylinder of the upper roller and the piston rod of the bending cylinder of the lower roller are manufactured in one piece.
  • Fig. La. schematically a rolling stand in 18 HS configuration
  • Fig. 1.b schematically a rolling stand in 4-high configuration
  • Fig. 1.c. schematically a rolling stand in 6-high configuration
  • the piston rods 1 are held firmly by means of a holding block 2 in Mae West blocks 3.
  • the cylinder housings 4 are moved vertically by means of pressure in the piston or ring side in guides in the Mae-West blocks 3, and by means of the pockets 5 in the cylinder body 4 transmit the bending forces to the roll chocks 7 via the bending pins 6, and accordingly to the roll necks of the intermediate roll 8 in the 18 HS mill stand (FIG. 1 a) or the work roll 9 in the 4-roll rolling stand (FIG. 1 b) or 10 in the 6-high roll stand (FIG. 1 c).

Abstract

L'invention concerne une cage de laminoir à 4 cylindres/6 cylindres/18 cylindres à décalage horizontal présentant une configuration en cassette, la force de flexion étant transmise aux tourillons de flexion (6) des empoises de cylindre (7) par l'intermédiaire d'ensembles piston-cylindre reliés aux blocs Mae West (3). Ainsi, le piston est relié solidement au bloc Mae West (3) sur la tige de piston (1), et les corps de cylindre (4) comprennent les tourillons de flexion (6) sur les empoises (7), de manière que la force de flexion puisse être directement transmise aux tourillons de flexion (6) des empoises de cylindre (7).
