Hot-metal ladle is an important part in continuous casting production line and its stress distribution has direct influence on its life. In the process of design and calibration of the large sized hot-metal ladle, it’s of great significance to determine the stress distribution of each part of the ladle for safely and reliably running the device. Based on 100t hot-metal ladle which is designed by Baotou Iron & Steel Group, a simulation of stress field was made by finite element software ANSYS 10.0 in the different dumping angles. Through modeling, loading, restricting and calculating, strain and stress field distribution of the hot-metal ladle were acquired. Finally, an assessment of strength and stiffness was made on the hot-metal ladle. The results show that in the process of tipping for the hot-metal ladle, maximum stress is 137MPa, maximum strain is only 0.681‰, maximum stress and strain have appeared in the stiffener plate which is located at the bottom of the trunnion, and strength and stiffness are qualified. The method which is convenient and practical, reasonable and reliable provides theoretical evidence for checking analysis and further optimal design of the hot-metal ladle.
