摘　　要：文章研究了KOCKS轧机三辊切线孔型生产圆棒时轧件的横截面积与KOCKS轧机孔型参数、轧件初始断面之间的关系,并给出相关数学模型。利用宝特棒材生产线上采集的数据,以轧件道次延伸率的计算值与实际值误差标准差最小为目标优化模型中的系数,使道次延伸率计算结果误差在±1%以内,说明模型可以为KOCKS孔型参数设计和优化提供参考。计算了轧件在KOCKS轧机孔型中轧制时的平均应变、应变速率、轧制力、轧制力矩等力能参数,并将轧制力矩的计算值与实测值进行比较,误差范围多在±5%以内,说明模型具有一定精度,可以为轧机负荷设定及调整提供参考。Tangent-profile caliber of KOCKS 3-roll reducing ＆ sizing block was used in rod and bar rolling. The relationship between the cross-sectional area of workpiece with the groove pass parameters, original cross-sectional shape and area of rolled stock were investigated. The analytical models for the cross-sectional area of workpiece had been proposed. According to the practical data from the rod and bar roiling production line of Special Steel Branch of Baoshan Iron ＆ Steel Co. , Ltd. , the parameters of the models were optimized to minimize the standard deviation of errors between the calculated and actual pass elongation rates. The calculation errors ranged in ±0. 1%, which indicated that the developed models could be used to make reference for roll pass design and optimization of KOCKS stands. In addition, parameters such as rolling pass mean strain, mean strain rate and rolling force and torque were calculated. Compared with the measured data, the errors of the calculated values of rolling torque ranged in ±5%, which indicated that the developed model had a good precision and could be used to make reference for rolling loads setup and adjustment.
