Abstract (en)
[origin: EP1857567A1] In a process to apply an anti-corrosion coating to sheet steel, the steel is pre-heated to a strip temperature under an inert gas and then cooled to a strip-entry temperature. The steel strip is then passed through a zinc bath, leaving a coating containing no more than 0.5 per cent Wt. aluminum. Surplus coating is then scraped off to leave a skin 3-20 mm thick each side. The steel strip is then allowed to cool, followed by application of an organic coating agent e.g. paint.
