摘　　要：研究分析了热轧轧辊温度分布及热凸度变化规律。试验结果表明,轧辊的热凸度变化明显受冷却条件及设备的影响,通过对轧机部分冷却集管和水嘴的改造,调整了冷却水在辊面的分布,使轧辊热凸度变化有了显著改善;经过一个轧制生产的周期,轧制带钢卷数与热凸度的变化规律中,F1工作辊的热凸度最大,F6工作辊的热凸度最小。Research and analysis of the rules of hot rolling temperature distribution and thermal crown changes, knowfrom the test results, the roll thermal crown change was significantly affected by cooling conditions and equipment, throughthe transformation of the mill part of the cooling pipe and nozzle set, adjust the cooling water in the roll surface distribution,the change of roll thermal crown with significant improvement. The change law of roll number and thermal crown is ana-lyzed by experiment. It is found that the thermal crown value of F1 work roll is the largest and the thermal crown value ofF6 work roll is the smallest after a rolling cycle.
