- the invention relates to the lubrication, as well as to the cooling of the metal strip and elements related to the cold rolling of said strip in continuous or reversible running in at least one rolling stand or rolling mill.
- said elements refer to a set of superimposed cylinders having parallel longitudinal axes and placed appreciably in at least one plane perpendicular to the direc ⁇ the tape tion.
- the longitudinal axis of one of the cylinders ⁇ is defined as an instantaneous rota axis ⁇ tion, parallel to a generatrix of the cylinder and passing through the center of mass of said cylinder.
- the present invention relates to the rolling of certain metal alloys involving the use of small diameter working rolls, as for example stainless steels, silicon steels, or certain al ⁇ nonferrous bindings .
- These metal alloys are rolled in installations comprising at least one multilayer roll cage, such as, for example, 12-High or 20-High rolling mills, that is to say equipped with 12 or 20 roll mills.
- cylinders As is known, small dia rolling cylinders ⁇ meter of a rolling stand not have enough rigidity ⁇ cient to withstand the rolling unabated efforts. They are therefore supported in the roll stand by cylinders and support rollers or support. A typical example of a 20-High mill is shown in FIG. 1.
