    摘要： This invention provides a rolling method and a rolling apparatus, for flat-rolled metal materials capable of stably producing flat-rolled metal materials not having, or having extremely little, camber. A rolling method for a flat-rolled metal material uses rolling equipment including a rolling mill and at least a pair of pinch rolls for clamping a rolled material on the exit side of the rolling mill having a mechanism in which either one, or both, of upper and lower roll assemblies have a mechanism for supporting a work roll by split backup rolls split into at least three segments in an axial direction, the split backup roll group having a construction for supporting both a vertical direction load and a rolling direction load acting on the contacting work roll and each of the split backup rolls independently having a load measuring device. The method comprises the steps of directly measuring, or calculating on the basis of a predetermined measurement value, either one, or both, of left-right balance of a rolling direction force acting on a rolled material from the pinch rolls and the left-right balance of a rolling direction force acting on the work roll of the rolling mill through the rolled material; and controlling a left-right swivelling component of a roll gap of the rolling mill on the basis of the measured value or the calculated value of the left-right balance of the rolling direction force.

    摘要： A cooling apparatus of thick-gauge steel plate having a plurality of pairs of constraining rolls, each comprising a top roll and bottom roll, constraining and conveying hot rolled thick-gauge steel plate and a plurality of spray nozzles spraying water on the top and bottom surfaces of the thick-gauge steel plate conveyed between the adjoining pairs of constraining rolls before and after each other in the conveyance direction, said cooling apparatus of thick-gauge steel plate characterized by arranging said plurality of spray nozzles so that:
    (i) the sum of the areas of the impact surfaces of the water sprays from the top surface side spray nozzles on the surface of the thick-gauge steel plate is in the range of 4 to 90% of the surface area of the steel plate between the roll outer circumferences at the closest distance between the pairs of constraining rolls and
    (ii) the sum of the areas of the impact surfaces of the water sprays from the bottom surface side spray nozzles on the surface of the thick-gauge steel plate is in the range of 4 to 100% of the surface area of the steel plate between the roll outer circumferences at the closest distance between the pairs of constraining rolls.
