Definitions

  • the subject of the invention is a displacement rolling mill axial being able, in particular, to present a great opening stroke, such a rolling mill being usable more specially for hot rolling of metals not ferrous such as aluminum.
  • a rolling mill generally includes two superimposed working rolls between which passes a metal plate or strip to be laminated, said rolls being subjected, for rolling, to a clamping force determining a certain crushing of the product.
  • each working cylinder is associated with a plurality of support cylinders arranged symmetrically on either side and on the other side of the clamping plane.
  • the different cylinders have their axes substantially parallel and are superimposed inside a cage with two uprights apart, each cylinder being centered on two aligned pins rotatably mounted, each via a bearing, in a holding chock which can slide inside a window in the corresponding amount of the cage and provided with guide faces defining a direction of sliding of the chocks parallel to the clamping plane.
  • the clamping force is generally applied by mechanical or hydraulic cylinders supported on one side on the cage and on the other on the chocks of one of the support cylinders, the other cylinder being blocked, so as to determine an approximation of the cylinders with a certain crushing effect of the passing product between the working cylinders.
  • the width of the product to be laminated which varies depending of the work program, may be less than the length of the active part of the working cylinders. These are therefore not loaded uniformly and can arch by causing crushing excessive on the lateral sides of the product.
