Abstract (en)

[origin: US4530858A] The present invention relates to a continuous coating process by a layer of Zn, Al or of a Zn-Al alloy for a cold laminated steel band comprising a heating thermic cycle, followed by a rapid cooling, a tempered coating in the metal bath of coating in fusion, at a temperature from 460 DEG to 500 DEG C., and a subsequent cooling, characterized in that after the tempered coating, the coated steel band is subjected to an over-aging treatment by maintaining the band at a temperature comprised between 430 DEG and 270 DEG C. during at least two minutes. This process is carried out in an installation comprising an over-aging chamber.
