ABSTRACT:
A hot-rolling equipment installation has a continuous casting apparatus linearly arranged with a simplified heating oven disposed uimmediately after an outlet of the continuous casting apparatus, a sizing press disposed immediately after an outlet of the simplfied heating oven, and rough rolling mills. The sizing press is installed at an inlet side of the rough rolling mills. The slab material is transferred from the continuous casting apparatus to the simplified heating oven and then reduced in width by the sizing press. The simplified heating oven raises the temperature of the edge portions of the slab so that the edge and center portions of the slab are made uniform in temperature. This prevents the edges from cracking during width reduction and subsequent rolling in the rough rolling mills.
