Definitions

  • the invention relates to a / 4-Rollen- / 6-Rollen / 18-HS roll rolling mill in cassette construction.
  • An essential requirement of a combined rolling stand is to be able to change between the two operating modes during a conventional roll change, without having to make alterations to the framework.
  • 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.
  • This object is achieved according to the invention in a 4-roller / 6-roller / 18-HS roller rolling mill in cassette construction, in which the bending force is transmitted via piston-cylinder units, which are connected to Mae West blocks, on the bending pins of the roll chocks , in that the piston is firmly connected to the piston rod with the Mae West Block and in that the cylinder bodies comprise the bending pins on the chocks of the rollers, so that the bending force can be transmitted directly to the bending pins of the roller chocks.
  • the piston rod of the upper cylinder bending cylinder and the lower roller piston rod are made in one piece.
  • 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 cylinder bodies are fixedly mounted in Mae West blocks and the bending force is transmitted via the piston rods and a guided intermediate piece on the bending pins of the roll chocks.
  • 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.
  • the hydraulic supply for the piston as well as the ring sides is provided by the piston rod.
  • the piston rods 1 are held firmly by means of a holding block 2 in Mae West blocks 3.
  • the cylinder housing 4 are moved vertically by pressurizing the piston or ring side in guides in the Mae-West blocks 3, and transmitted by means of the pockets 5 in the cylinder body 4, the bending forces on the bending pin 6 on the roll chocks 7 on this, and accordingly on the roll necks of the intermediate roll 8 in the 18 HS rolling stand ( Fig. 1a ) or the work roll 9 in 4-roll rolling stand ( Fig. 1b ) or 10 in the 6-high mill stand ( Fig. 1c ).
