摘要： The invention concerns a method of heat-treating thin sheet which has been coated with zinc and/or aluminium by hot dip galvanization. The invention is characterized in that, immediately after the coating applied to its surfaces in the hot dip bath has hardened, the thin sheet is heated for between 2 and 10 seconds to a temperature which is between 20 and 100 DEG C above the liquidus temperature of the coating material and is then cooled to ambient temperature.

摘要翻译： 本发明涉及一种通过热浸镀锌热处理涂覆有锌和/或铝的薄片的方法。 本发明的特征在于，在热浸浴中施加到其表面上的涂层刚刚硬化之后，将薄片加热2至10秒至温度高于液相线温度20至100℃ 然后将涂层材料冷却至环境温度。
