| 摘要 |
The invention relates to a method for producing coated high strength low alloy steel. A strip of steel is cleaned from rolling oil, is heated to the temperature range A1 to A3 in a protective atmosphere, is soaked and subsequently quenched in a zinc-aluminum bath for a short time sufficient to adhere a zinc coating to the steel surface, whereafter the steel strip is rapidly cooled to a temperature below 300 DEG C., to obtain a dual-phase steel structure. |
