N2 - Purging plugs are widely used in the secondary refining process, and its service life determines thedowntime and usage efficiency of the whole ladle. This study focuses on comparing the heat transfer andthermomechanical behaviour of purging plug with different slits to obtain the reason for the long servicelife of purging plug by thermal-structure coupling method. The numerical results showed that the moderationof temperature distribution is achieved by changing the slit shape and the reasonable arrangementof the circular slits. Furthermore, the circular slits can alleviate the stress concentration phenomena, andcircular slits are better for decreasing the axial stress in the purging plug, which occurred at the positionlocated 0.323 m above the bottom face, and its distance from the centre is 0.04 m.
