摘要
以宝钢 2 0 50热连轧机工作辊轴承座的热变形故障作为研究对象 ,详细分析了轴承系统的内热源 ,确认轴承内部的摩擦热是轴承系统温升的主要热源 ,本文采用有限元方法 ,同时利用三维有限元温度场程序和SAP5软件 ,研究了轴承座的热变形场分布规律。
The heat distortion of workroll bearing chock of 2050mm hot strip rolling mill employed in Baoshan continuous rolling mill is studied using finite element method(FEM),3D FEM temperature distribution program and SAP5 software. The internal heat sources of bearing system is analyzed carefully and it was found that the internal friction heat in the bearing system is the major heat source that results in temperature rising. The law of heat distortion distribution of bearing chock is also discussed.
