Analysis on thermal stress for stainless steel AOD converter of 120 t

Thermal stress simulation analysis is carried out on the newly designed 120 t stainless steel AOD converter. Firstly pretreatment is made on the CAE model with the main stream CAE software HyperMesh universally adopted over the world and then analysis conducted on the temperature field and thermal stress simulation of the converter system in operation using the finite element analysis software ANSYS and finally post treatment made on the results of the simulation analysis with the software HyperMesh once more. In this way the characteristic data of thermal stress for the 120 t stainless steel AOD converter in operation is obtained and the result of the specific analysis is beneficial to implementation of the design and production maintenance.
