以具有纳米绝热材料内衬的新型钢包为研究对象,通过建立三维有限元模型,运用ANSYS软件分析该种新型钢包与传统钢包在盛钢工况下的应力分布,并研究纳米绝热材料的导热系数、弹性模量、热膨胀系数对新型钢包应力场的影响。结果表明,盛钢工况下新型钢包的应力分布明显优于传统钢包,新型钢包包壳的最大应力比传统钢包包壳的最大应力减小22MPa;在一定范围内,新型钢包包壳的应力随纳米绝热材料导热系数和热膨胀系数的降低以及弹性模量的增大而逐渐减小。
With a new type ladle with heat insulation nano-material lining as the research object, the 3D finite element model was established, and the stress field of the new type and traditional ladles were analyzed by ANSYS under the condition of steel holding. The effects of thermal conductivity, elasticity modulus and thermal expansion coefficient of heat insulation nano-material on the stress field of the new type ladle were investigated. The results show that stress distribution of the new type ladle is better than that of the traditional ladle under the condition of steel holding, and the maximum stress of the new type ladle shell is 22 MPa less than that of the traditional one. Within a certain range, the stress of the new type ladle shell gradually decreases with the decrease of the thermal conductivity and thermal expansion coefficient and increase of elasticity modulus for heat insulation nano-material.
