摘要
转炉的连接装置是转炉系统的重要部件之一。为找出连接装置的应力变化规律和危险点,以120t转炉的连接装置为研究对象,用UG软件对转炉整体建模并算出不同倾角下倾动力矩,确定出三种极限工况,并用ANSYS Workbench软件对转炉整体分析,找出连接装置处应力变化规律,对连接装置主要零件强度分析,对比理论分析和有限元分析。结果表明:理论分析与有限元结果趋于一致,连接装置处存在应力传递不均匀现象。对连接装置的应力变化规律进行分析并找出改进方法,为转炉连接装置的优化和改进提供理论参考。
The connecting device of converter is one of the important parts of converter system. In order to find out the stress vari- ation law and dangerous point of the connecting device, taking 120t of converter connecting device as the research object, using UG to the whole of converter modeling and calculate the tilting moment under different angle, determine the three types of extreme working conditions and the overall analysis of the converter using ANSYS Workbench, to find out the stress variation law of the connecting device, and intensity analysis of main parts of connecting device, comparison of theoretical analysis and finite element analysis. The results show that ：theoretical analysis and finite element results are consistent, the stress transfer in the connecting device is not uniform. Analysis of the stress variation law of the connecting device and put forward improvement measures, provide a theoretical reference for the optimization and improvement of converter connecting device.
