Flat product composed of a metal material, in particular a steel material, use of such a flat product and roller and process for producing such flat products
Abstract:
With the invention a metallic flat product can be systematically made available with such a fine, stochastic or quasi-stochastic surface texture that after a typical automotive paint application it is only minimally perceptible, if at all, by the human eye. At the same time, in the case of a surface topography constituted according to the invention, the transition between the peak plateaus and the valleys takes place via steep flanks. In this way, it is achieved that the morphology of the sheet metal surface is practically independent of the actual depth of the valleys. As a result therefore, the morphology of the sheet metal surface of a metallic flat product according to the invention is also independent of the skin-pass rate, which is obtained when the fine metal texture is produced by skin-pass rolling.
