金属圆棒材连轧过程动态特性分析
|
摘要
随着现代化工业技术和生产工序自动化的迅速发展,对棒材特别是有色金属棒材的品种规格、尺寸精度及性能都提出了更高的要求。在棒材连轧咬入过程产生的过大的动态速降不仅有堆钢的危险,而且也给各机架间轧件微张力调节带来困难。因此,对咬入过程动态速降进行研究,具有十分重要理论研究意义和实际工程应用价值。
为了提高棒材产品的质量,主要从提高连轧机组轧制参数的预设定精度着手,在本文中,通过对驱动系统的工作原理、控制方法、系统常用建模方法等各方面的深入了解,设计双闭环控制系统并建立单机架驱动模型、速度模型和张力模型。在模型的实现方面,利用软件Matlab中的Simulink动态结构图实现了系统仿真,为研究动态速降对棒材尺寸精度的影响提供了一种很好的分析方法。
本文通过将实测值与仿真结果比较,证明了所建模型能够很好的反映实际工况,通过改变预设定参数值,得到参数对工作过程的影响规律,通过分析改进的模型,可以较有效的改善动态速降的负面影响。本文的研究结论在生产现场得到了验证,提高了棒材产品的质量。
As the rapid development of modern industrial technology and production working procedure automation, it makes higher demands on bar of the quality specification, dimensional precision and performance. In the bar rolling process, the larger dynamic speed droop is not only dangerous, but also difficult to the micro-tension adjustment. Therefore, the study on the analysis of the dynamic speed droop is quite important meaning to improve the quality of rolling bar product.
In order to improve the quality of rolling bar product, the thesis mainly research on the pre-setting accuracy of the rolling parameter. In this thesis, it has comprehensively been analyzing the working theory, control method, modeling methodologies to establish the mathematics model of the drive system. Design the double-closed-loop system and establish the single frame drive model, advancing slip model and the tension model. In aspect of model realization, system simulation has been realized through using dynamic structures of Simulink of Matlab software , it provides a good way to analysis the inpact between the rod demensional accuracy and the dynamic speed droop.
In this paper, compared with simulation result and measured value, it prove that the model can reflect the real conditions. Trough changing the parameter, it gets the influence law to work process. The research result in this thesis has been confirmed in the work field and the production is improved.
