| 摘 要： | 利用ANSYS有限元分析软件对钢包透气砖在精炼奈件下(不同吹氩压力、精炼温度)的应力场分布进行了计算研究.结果认为,铝镁质透气材料结构应力与其热膨胀系数成正比变化;透气砖工作面狭缝尖端处应力最大,是其非工作底面的6.62倍,并且从非工作底面到工作面狭缝尖端应力增加最快;吹氩压力对透气材料应力的影响可忽略不计;精炼温度提高50℃,工作面狭缝各部位应力相应增加1%～2%. |

| Abstract: | The stress field distribution of purging plug at different argon blowing pressures and different refining temperatures was analyzed by ANSYS FEM soft ware.The results show that:(1)The stress of alumina-magnesia based purging plug is in direct ratio with its thermal expansion coefficient;(2)The slot tip in working face of purging plug has the maximum thermal stress,which is 6.62 times that of non-working bottom face,and the stress of slot tip increases most quickly from non-working bottom face to working fac... |
