Abstract
The ladle is a kind of important storage and transportation equipment under high temperature condition in the ferrous metallurgical industry.In order to investigate the ladle's stress distribution and composition,a simulation analysis of the 115 t ladle was made using the finite element method.The results showed that the thermal stress was the main part of the ladle's integrated stress,and that most of the stress's large values appeared near the ladle body's welding seams.Therefore,in order to ensure the safe and reliable operation of the ladle,in the design and manufacture,the thermal expansion coefficient of the lining should be lower,the stiffness gradient of the ladle body should be lower,and welding quality should be higher.关键词
