Optimizing the Structure of Ladle Bottom Based on Finite Element Method

摘要

Ladle is a sort of important container in metallurgy industry, and its lifetime is very important for the natural production of enterprise. The stand or fall of refractory lining of ladle decides its lifetime, yet thermal stress is the direct reason of causing refractory lining breakage. This paper designs the structure of ladle mainly by changing the structure of bottom with finite element method, and puts forward three scheme models. By analyzing and comparing stress field of the three ladle models, this paper finally puts forward a optimization scheme. The experiment results indicate that the lifetime of ladle gains obvious increase, and the rationality and practicability of the scheme have been proved.
