Flexible rolling process to manufacture sheet metal component after hot or cold dipping and further mechanical and/or chemical treatment

摘要

In a process to manufacture sheet metal component, a strip of hot or cold steel passes through a hot or cold bath in which it is subjected to hot dip galvanic treatment. The strip is then subjected to a flexible rolling process at a sequence of different pressures to produce strip of a predetermined thickness. After rolling, either the coating thickness is of varying thickness. The higher the rolling pressure, the thicker the coating, and/or and/or after the flexible rolling the coating is subjected to a mechanical or chemical surface treatment process to set a desired emissivity or heat absorption capacity.
