Definitions

  • the invention relates to a method and an installation for the production a thin sheet or foil by rolling. She also has the use a sheet or foil produced therewith and a rolled thin sheet or film of a particular material to the object.
  • Lightweight structural components are often referred to as "honeycomb" structures manufactured, i. as a composite body with a middle layer of honeycomb between two cover layers. To achieve the lowest possible weight, should the middle layer and the cover layer made of the thinnest possible material, preferably a film.
  • the object of the invention is a thin sheet or a film of high surface quality to provide a difficult to deform metallic material.
  • the sheet or the film is produced by rolling, wherein in the forming zone to a predetermined Temperature heated rolling stock with non-heated work rolls made of ceramic Material is rolled in a protective gas atmosphere. While one Film has a thickness of less than 0.1 mm, the thickness of a thin sheet more than 0.1 mm and less than 2 mm.
  • a ceramic Material for the work rolls is preferably a nitride or oxynitride ceramic, in particular zirconium nitride or zirconium oxynitride.
  • the temperature of the rolling stock in the forming zone is preferably at least 0.3 times, in particular at least 0.4 times, the homologous temperature of the metallic or intermetallic material.
  • Homologous temperature [K] operating temperature [K] / melting temperature [K]
  • metallic or intermetallic materials according to the invention are preferably used brittle or high-strength materials, in particular Low density materials. So is preferably the brittle / ductile transition temperature of the metallic or intermetallic material the room temperature or the solidification exponent is above 0.3.
  • metallic materials for example, molybdenum, Tungsten, nickel, beryllium or titanium alloys are used.

  • the twelve rollers consist of the upper and lower Work rolls 4 and 5 and the upper and lower support rollers 6-10 and 11-15, wherein the upper back-up rolls 6 and 10 and the lower back-up rolls 11 and 15 are driven.
  • At least the twelve rollers 4-15 and prefers the reels 2, 3 are arranged in a cabin, not shown, in which a Inert gas atmosphere is located.
  • the drives of the rollers 6, 10 and 11, 15 and the reels 2, 3 are outside this cabin.
  • the drive rollers 4, 5 are made of a ceramic material.
  • the back-up rolls 6-15 are made of steel and are cooled, for example internally by means of water cooling.
  • the rolling stock 17 is coupled to the reels 2, 3. It is powered by current heated conductively by the rolling stock 17.
  • the electrical contact takes place e.g. by contact rollers, not shown, or brushes at the contact points 18 and 19 on both sides, ie in front of and behind the roll stand 1.
  • the rolling stock 17 is reversibly formed in the roll stand 1. After every Rolling passes are the drives for the driven back-up rolls 6, 10 and 11, 15 and for the two reels 2, 3 stopped and again in the opposite Approached direction to transform the rolling stock 17 to the next end.
