Definitions

  • the invention relates to a method for producing sample sheets of steel, such as corrugated or magnifying sheets.
  • a device for producing a sample sheet with a basic thickness of 2 mm and a sample height of 2.5 mm is known from GB-A-4393 - A.D. 1893.
  • narrow roll stands are provided, with which only very narrow sample sheets could be produced.
  • sample sheets are manufactured by hot-rolling broadband on broadband lines to enable large widths to be produced, although it has hitherto been difficult or an unsolved problem to produce sample sheets with the dimensions described at the outset, since surface defects and unevenness in the pattern height, hardening occurred and unwanted markings, so-called “stretch marks”.
  • the ratio of the basic thickness to the sample height is usually at least 3: 1, whereby the minimum basic thickness is 3 mm.
  • Such sample sheets have a relatively high weight and are therefore as clothing elements, for. B. for trucks, have not previously been used.
  • a sample roller as an upper roller with a cut pattern is installed in the last stand of the broadband mill. The rolling of these sample sheets has hitherto been carried out dry, i. H. without using a lubricant.
  • the invention has for its object to provide a method of the type described above for the production of sample sheets, light weight on a broadband line, in which the difficulties and disadvantages previously encountered, such as. B. "stretch marks" and other surface defects can be avoided.
  • This object is achieved in that the pattern is rolled into the sheet with lubrication.
  • a mixture of lubricating oil, water and steam is advantageously used as the lubricant.
  • the method is preferably carried out in such a way that the pattern roll used as the top roll in the last roll stand of the broadband mill is directly lubricated, in particular by spraying the lubricant onto the pattern roll surface.
  • FIGS. 1 and 1a illustrating a corrugated sheet
  • FIGS. And 2a illustrating a magnifying sheet, each in plan view and in section.
  • sample sheet with diamond-like elevations can be seen, the height (sample height) of which is denoted by a.
  • the basic thickness of the sheet is designated by b; b to a are in the ratio given above, u. between 1.3: 1.
  • FIGS. And 2a a magnifying glass sheet with magnifying glass elevations is shown in FIGS. And 2a, the magnifying glass height being designated a and the basic thickness being designated b.

Procédé pour produire des tôles cannelées en acier, telles que des tôles striées ou larmées, qui présentent une épaisseur de base de moins de 2,5 mm et dans lesquelles le rapport épaisseur de base à hauteur des reliefs est de 2 : 1 à 1 : 1, de préférence de 1,4 : 1, par laminage à chaud d'une bande large sur un train de laminage à larges bandes, caractérisé en ce que la formation des reliefs dans la tôle par laminage s'effectue avec lubrification.
2. Procédé suivant la revendication 1, caractérisé en ce qu'on utilise comme lubrifiant un mélange d'huile lubrifiante, d'eau et de vapeur d'eau.
3. Procédé suivant la revendication 1 ou 2, caractérisé en ce que le cylindre à reliefs utilisé comme cylindre supérieur dans la dernière cage du train de laminage à larges bandes est lubrifié directement, de préférence par pulvérisation du lubrifiant sur la surface du cylindre à reliefs.
