ABSTRACT:
A blank for a wide flange beam is produced by feeding a flat slab to a break-down mill in which a box caliber, one or more forming calibers and a sizing caliber are formed by a pair of rolls, and rolling the material in a former stage of the rolling process so that the rectangular ratio of the rolled material is substantially equal to the rectangular ratio of the slab.
