在分析现有转炉裙罩系统的基础上,针对一种新型转炉裙罩结构,建立了转炉裙罩系统的三维实体模型;基于有限单元法,建立了转炉裙罩系统三维静力分析有限元模型,针对转炉5个工作位置,分为四种工况,对该系统在实际惯性载荷作用下的应力和变形进行了数值仿真;分析结果表明,该系统为超静定结构,稳定性和可靠性高,系统应力低于材料许用值,且主要集中在连杆机构上,有效地保护了挡渣裙板,降低了设备维护费用,满足实际使用要求,具有一定的工程应用价值。
Based on the analysis of the existing converter skirt system, a three-dimensional solid model of the converter skirt system was established for a new converter skirt structure. Based on the finite element method, a three-dimensional static analysis finite element model of the converter skirt system was established. , Five working positions of the converter were divided into four working conditions. The stress and deformation of the system were numerically simulated under the actual inertial load. The analysis results show that the system is of statically indeterminate structure, stability and reliability High and system stress lower than the allowable value of the material, and mainly concentrated on the connecting rod mechanism, which effectively protects the slag-blocking apron, reduces the equipment maintenance cost, satisfies the actual use requirements, and has certain engineering application value.
