摘　　要：南钢3 500 mm炉卷轧机生产5 mm×3 150 mm规格Q960高强钢板时,板型瓢曲严重。通过对加热温度、卷取张力、卷取速度、卷取炉炉温、道次压下率等轧制工艺参数进行优化改进,显著改善了热轧态板型,钢板不平度由初期的15～25 mm/m降低至6～12 mm/m,为保证后续调质热处理板型控制效果提供了良好的基础。Q960 high strength steel plate of 5 mm thickness × 3 150 mm width produced by Nangang 3 500 mm Steckel Mill encounters serious buckling defect. By optimizing rolling processes such as reheating temperature,coiling tension,coiling speed,coiler furnace temperature,pass reduction,as rolled plate profile is significantly improved,un-flatness is reduced from initial 15～25 mm/ m to current 6～12 mm/ m,which provides the basis for maintaining a good profile control result after subsequent quenching and tempering.
