PROBLEM TO BE SOLVED: To provide a method for manufacturing a taper steel plate having excellent flatness in a lengthwise direction.SOLUTION: In a method for manufacturing a taper steel plate having excellent flatness, when a hot reversible rolling mill including a work roll bender rolls a taper steel plate which has a taper part having a plate thickness continuously changing in a steel plate lengthwise direction, the ratio of a load of the work roll bender and a rolling load is made constant, and the load of the work roll bender is changed in association with change of the rolling load at a plate thickness change point from a thin part/a thickness part or a plate thickness change point from a thickness part/a thin part. |
