Abstract
A sheet bar having a thickness of 20 to 50 mm, as continuously cast by a sheet bar caster, is passed as it is through a first sheet bar twister and is then wound in an up-end state into an up-end sheet bar coil. Then, this up-end sheet bar coil is rewound, passed through a second sheet bar twister, finish-rolled and wound into a hot coil. As compared with the slabbing—high draft rolling process of the prior art, the invention is advantageous in that it can improve the quality, production yield and production efficiency and can reduce the cost for an apparatus such as the cost for its construction and maintenance.
