Abstract
The creep deformation of the cast copper cooling staves was researched based on the steady temperature field by using thermal - mechanical coupling finite element transient analysis method and ABAQUS software. The results show that the creep deformation only under the effect of thermal stress is slight and negligible compared to the deformation generated by thermal expansion. The total tress is not adequate to crack the stave body. Therefore, the cast copper stave can meet the requirements of blast furnace longevity.
