针对国内某4200mm中厚板轧机首次采用SmartCrown板形控制新技术,采用ANSYS9.0建立了辊系三维有限元模型,通过有限元仿真分析发现在SmartCrown工作辊和常规凸度支持辊的辊型配置下,采用SmartCrown的轴向移位变凸度技术,中厚板轧机的板形控制能力大大增强,但是辊间接触压力的不均匀性和接触压力峰值明显增大。在结合VCR支持辊优势的基础上,提出了4200mm中厚板轧机SmartCrown工作辊相匹配的辊形SVR(SmartCrown-VCR Compounded Roll)。对比分析发现采用SVR支持辊后可以明显减小辊间压力尖峰、均化辊间压力分布和提高轧机对板形调控能力。
For the first time a 4200mm plate mill in China adopts SmartCrown plate-shaped control technology, the three-dimensional finite element model of the roller system is established by ANSYS9.0. Through the finite element simulation analysis, the roll configuration of the SmartCrown work roll and the conventional convexity support roller is found out. , The use of SmartCrown axial displacement crown technology, plate-shaped control of plate rolling mill greatly enhanced, but the contact pressure between the roller unevenness and contact pressure peaks increased significantly. Based on the advantages of the VCR backup roll, a SmartCrown-VCR Compounded Roll (SMR) matching 4200mm plate mill SmartCrown work roll is proposed. The comparative analysis found that the adoption of SVR support roller can significantly reduce the pressure spikes between the rollers, homogenize the pressure distribution between the rollers and improve the mill’s ability to regulate the shape of the plate.
