摘要：
A process for hot working a continuous-cast bloom or a steel ingot, the process comprising the steps of: (1) cooling a bloom produced by continuous casting or a steel ingot produced with a mold to bring the surface temperature thereof to 50.degree. to 150.degree. C. higher than the Ar.sub.3 transformation point thereof; (2) quenching the bloom or the steel ingot in such a way that its interior remains red hot while the surface is transformed to have a bainite structure; and (3) heating the bloom or the steel ingot in a furnace followed by hot shaping.
