Abstract

PURPOSE: To reduce crop losses by changing and adjusting a ratio between an edge draft amount of a hot rolled slab by an edging press and an edge draft amount by a vertical rolling mill in the uppermost position in a rough rolling mill group.
CONSTITUTION: A hot rolled slab 1 casted by a continuous casting machine, etc. is largely, first, edged by an edging press P and then is alternately subjected to edging and thickness drafting by a vertical rolling mill group of VSB, E2, E3... and a horizontal rolling mill group of R1, R2.... The slab 1 is then rolled to have target dimensions, that is, the target slab width and slab thickness on the outlet side of a rough rolling mill group 2. Crops of the top and rear end parts of the slab 1 after rolling are cut by a crop shear CS. In that case, the relation between an edge draft amount by the edging press P and an edge draft amount by the vertical rolling mill VSB is properly changed and adjusted. The crop amount of the slab rear end part is brought to be about 0 mm by bringing the ratio of (an edge draft amount by the vertical mil)/(the total edge draft amount of an amount by the edging press P and an amount by the vertical mill) to be about 0.09.
