    摘要: A steel strip heated to a temperature above a recrystallization temperature is passed through a cooling unit including a plurality of cooling rollers cooled by cooling water flowing through the interior thereof. The steel strip is caused to pass alternately about upper and lower surfaces of the cooling rollers. By raising and lowering alternate cooling rollers, the contact angle and therefore the contact area, i.e., the contact time between the strip and the cooling rollers is varied to change the cooling rate. When the cooling rollers are separated from the strip. Cooling water is filled into the cooling unit to directly cool the strip. Cooling gas may be ejected against the strip before it enters into the cooling unit.

    摘要: In a continuous hot-dip galvanizing process, the temperature of a travelling steel strip just before said strip is introduced into a molten Zn bath is controlled below the bath temperature, preferably at 380.degree.C. to 420.degree.C., to avoid generation of dross in said bath and impairment of said galvanized film.
