<p>PURPOSE:To improve productivity even in the case of rolling a thin strip by prorating the rolling stock of the strip thicker than a hot slab to the same hot slab and executing rolling from the thick strip at the time of rolling the thin strip from the hot slab. CONSTITUTION:The thin strip 3A is rolled from the hot slab by a hot strip mill line 1. The rolling stock of the thin strip 3A, the passing speed of which is kept low for the worry of generating a trouble during the passage, and the rolling stock of the thick strip 3B with which the troubles are less generated than with the thin strip during the passage are prorated to the same slab in the stage of commanding the rolling of the thin strip 3A. The thick strip 3B is disposed to the preceding end side and the rolling stock of the thin strip 3A is disposed in succession thereof, by which the thick strip 3B and the thin strip 3A are continuously rolled. The productivity is improved without generating the passing trouble by the above-mentioned method.</p> |
