摘 要: | 针对某2250常规热连轧产品的断面楔形问题进行研究,运用有限元法建立静态仿真模型,定量计算轧件跑偏和来料楔形遗传对热轧出口带钢断面楔度的影响,并通过实际生产数据的采集分析验证了模型计算结果的准确性。提出优化精轧立辊及侧导位的对中精度和开口度裕量,加强轧制过程对中性,并通过投用粗轧强力侧导位、优化粗轧工作辊辊形和加强手动调平控制改善粗轧来料楔形,使热连轧机组因楔形产生的板形三级品率从47%下降到10%以内,取得了明显的效果。

Analysis and Control of Strip Wedge in 2250 Conventional Continuous Hot Rolling |
| |
Abstract: | This study focused on the product section wedge of one wide strip conventional hot continuous rolling in China. Through finite element method, it established static simulation model, calculated the quantitative effect of work piece deviation and incoming wedge inherit on strip section wedge value at the outlet of hot continuous mill, and validated the calculation result with the practical production data. The author optimized alignment accuracy and opening gap margin of finish vertical rolling and side guide to enhance the alignment during the course of rolling, and also used rough rolling strong side guide, optimized rough rolling roller contour and advanced manual leveling control to improve the incoming wedge of rough rolling; consequently it reduced the 3rd grade shape products rate, that was caused by wedge in the hot continuous mill, from 47% to 10%. |
