基于ANSYS程序的钢包用不同材质滑板温度场研究

Research on temperature field of sliding plates of different materials for ladles based on ANSYS

根据钢包用滑板使用环境,施加初始条件和边界条件,利用ANSYS软件,对目前使用的铝碳、铝锆碳、镁碳及尖晶石4种材质滑板进行温度场模拟分析,发现当板型固定时,镁碳滑板使用过程中整体温度偏高,将带来机构的热疲劳损坏;而铝锆碳滑板内部温降明显,特别是在距注孔中心60~120 mm范围内温度急剧降低,将带来较大的热应力,造成使用过程中滑板内的小裂纹扩张形成大裂纹,造成滑板损毁,使用寿命降低。

According to the service condition of the sliding plates for the ladles,the initial conditions and boundary conditions were set.Using ANSYS software,the temperature field simulation analysis of four sliding plates of alumina-carbon,alumina-zirconia-carbon,magnesia-carbon and spinel was carried out.It is found that when the plate type is fixed,the overall temperature of the magnesia-carbon sliding plate is higher,which brings thermal fatigue damage to the mechanism,but the internal temperature of the alumina-zirconia-carbon sliding plate drops obviously,especially in the area of 60-120 mm from the injection hole center,which brings large thermal stress,expanding small cracks in the sliding plate during service,and reducing the service life.
