- the thickness of the thin sheet or the film, the or produced according to the invention is preferably at most 200 .mu.m, in particular at most 100 microns, so for example 70 microns or less.
- the device for heating the rolling stock in the forming zone on a Temperature for materials without a brittle / ductile transition at 0.3 times, preferably 0.4 times the homologous temperature and for materials with a brittle / ductile transition above the brittle / ductile transition temperature is, for example, by thermal radiation or inductive respectively.
- a conductive heating is performed, i.e. the rolling stock is heated by electrical resistance heating.
- an electric Contact to the rolling stock is preferably on both sides, ie in front of and behind the work rolls.
- the contact points for example be formed by contact rollers and / or brushes, which engage the rolling stock.
- a protective gas atmosphere As a protective gas It is preferred to use a noble gas, in particular argon.
- the forming speed should be more than 10 s -1 , and the rolling speeds for economic reasons at least 0.1 m / s, in particular at least 0.5 m / s.
- the vertical rolling force exerted by the work rolls on the rolling stock is preferably at least 3000 kN.
- the thickness of the rolling stock is preferably more than 1 mm, for example 2 mm or more.
- the reduction of the rolling stock per rolling pass is preferably at least 10%, in particular at least 20%.
- a reversing is performed with a Reversierwalzgerüst.
- Equipment manufactured film can be used for different purposes.
- the film rolled according to the invention may be e.g. made of a nickel / solder alloy be used as a solder foil.
- the rolled film according to the invention is suitable for the production of Lightweight structural components suitable for the aerospace industry.
- So can from the Film has a "honeycomb" structure, i. a composite structure of a middle layer made of honeycomb between two cover layers.
- the rolled film is cut into strips, for example, which folded and connected to the honeycomb of the middle class be, for example, by welding, whereupon the two cover layers from the film at the middle layer, e.g. be secured by welding.
- the "honeycomb” structure according to the invention may e.g. in an engine in the exhaust chamber can be arranged, thereby also the noise emission decrease.
- the structure can also be the rubbing surface for the turbine blades form.
- the "honeycomb” structure may e.g. in space travel be used as a thermal protection panel.
- the structure can also be used for other purposes, for example in vehicle construction.
- the rolling mill has a twelve-roll stand 1 with arranged on both sides Reels 2, 3 on.
- 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. This process is repeated until the desired film thickness is reached, which determined with a Banddickenmeß réelle not shown can, for example, according to the laser-optical triangulation principle is working.
- the rolling stock 17 used as the starting material is a Sheet of ⁇ -TiAl with a thickness of 3 mm.
- the work rolls 4, 5 exist made of zirconium nitride. They have a diameter of 40 mm and a bale length of 140 mm.
- the rolling stock, which has a width of 100 mm, is conductively heated to a temperature of 900-1200 ° C. It will be a reverse rolling with a reduction of 20-25% per roll pass.
- the rolling speed is about 0.5 m / s.
