| 摘 要： | 为改善轧机的板形调控性能，在分析连续变凸度(Continuously variable crown，CVC)辊形技术的板形控制特性的基础上，开发出用于热带钢轧机的线性变凸度(Linearly variable crown，LVC)工作辊辊形技术及其相应的板形控制模型。LVC技术的板形调节能力与窜辊量成线性关系，同时与带钢宽度成近似线性关系。在满足宽带钢板形控制要求的同时，提高轧机对窄带钢的板形控制能力，使轧制各种规格带钢时所需弯辊力处于合理的的幅值。在1 700 mm热带钢轧机上一年多的工业应用表明，采用LVC工作辊后，板形控制精度提高30%以上，尤其是轧制高强度钢种时，凸度下降显著，轧制公里数一般都大于55 km，磨损辊形和轧辊消耗与常规工作辊基本一致。
