ABSTRACT OF THE DISCLOSURE A steel strip heated to a temperature above recrystal- lization 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 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. Where the strip is cooled indirectly, so that it is passed about a series of cooling rollers cooled by water flowing through their interior, it is possible to cool the strip without forming oxide films thereon. The type of cooling is selected according to the type of the steel strip. With this method and apparatus it is easy to adjust the cool- ing rate of a steel strip.
