Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To improve the pickling property of a tail overlap part of a hot rolled coil and to produce a hot rolled steel plate excellent in the pickling property. SOLUTION: When a hot rolled coil is cooled after hot rolling and coiling steel, the steel plate surface of a tail overlap part 43 in the most outer periphery of the hot rolled coil is preferentially spray cooled with water and then the whole coil is cooled. At the neighborhood of the tail overlap part 43 in the most outer periphery of the hot rolled coil, scale grows extremely thick in comparison with a coil normal part, the whole scale layer is transformed to Fe3 O4 inferior in pickling property. When the tail overlap part 43 in the most outer periphery is preferentially spray-cooled with water, the pickling property of the tail overlap part 43 is improved, the pickling property of the hot rolled coil tail is prevented from lowering. Its effect is particularly large in a high temp. coiled coil of >=640 deg.C a coiling temp.  In this case, after the steel plate surface of the tail overlap part 43 in the most outer periphery of the hot rolled coil is preferentially spray-cooled with water from >=450 deg.C, it is better that the whole coil is water-cooled down to <=250 deg.C.
