摘要/Abstract

摘要： 针对工作辊“长径比”大且辊径绝对值小的轧机在轧制过程中，工作辊产生较大水平挠曲的问题，在考虑设备与工艺特点的基础上，研究了工作辊发生水平挠曲时的载荷分布情况，推导了新的辊间压扁系数模型，并以典型规格产品为例，定量分析了工作辊出现水平挠曲时，单一影响因素变化对辊间压扁系数的影响。为了验证模型，在完成相关理论分析的基础上，编写了预报软件，并给出了现场实验结果。

关键词: 工作辊, 水平位移, 轧辊压扁, 接触弧

Abstract: In the rolling processes, the mill work rolls with large “aspect ratio” and small absolute value of roll diameter had a greater level of work roll deflection problems. Considering characteristics of equipment and processing parameters on rolling mills, load distributions of the work rolls under horizontal bending was studied in detail, and a new roll flattening coefficient model was deduced. Taking a typical product as an example, changes of roll flattening coefficients were analyzed quantitatively when a single factor was changed in the horizontal displacements of the work rolls. In order to verify the model, a forecasting software was compiled based on the relevant theory, and the field experimental results were given herein.

Key words: work roll, horizontal displacement, roll flattening, contact arc
