The invention discloses a high-performance steel rolling method which comprises the steps of coiling a thin steel strip into a spiral steel coil, and rolling for the second time, wherein the spiral steel coil is a hollow cylinder body, and each side wall of the spiral steel coil is formed by tightly gluing multiple layers of thin steel strips; and during rolling for the second time, sequentially heating the spiral steel coil through a heating furnace and carrying out a rough rolling process and a finish rolling process so as to obtain finished steel through rolling. The finished steel rolled through the high-performance steel rolling method provided by the invention has a good mechanical property. 本发明公开了一种高性能钢材轧制方法，将薄钢带卷曲成螺旋钢卷进行二次轧制，所述螺旋钢卷呈空心圆柱体，且所述螺旋钢卷的每处侧壁均为若干层所述薄钢带紧密贴合而成，在进行二次轧制时所述螺旋钢卷依次经过加热炉加热、粗轧工艺和精轧工艺轧制成成品钢材。本发明高性能钢材轧制方法轧制出的成品钢材的力学性能好。
