Abstract

Apparatus and process for the manufacturing of microcrystalline metallic materials in band form, wherein the chemical compositing for the cooling roller given in ranges within which the upper surface roughness is reduced, the geometry is improved, the presence of microcracks is eliminated or reduced and the ductibility of the band is increased.
