Sažetak

In this paper, high-temperature tensile creep tests were conducted at 1,050 °C, 1,100 °C and 1,150 °C under different stresses. The high-temperature mechanical properties and creep behaviour of continuously cast slab made of 0Cr18Ni9 stainless steel were obtained, and the creep constitutive equation was fitted. Based on this, bulging deformation of a three-dimensional slab model was simulated. The results showed that the maximum bulging deformation of the wide side and the narrow side along the casting direction were approximately 1.7 times and 1.3 times larger than the deformation when creep was not considered, respectively. By changing the roller pitch, it was found that the larger the roller pitch was, the larger the bulging deformation of the wide side and the larger the creep deformation proportion was. Similarly, the bulging deformation and the creep deformation proportion in the narrow side also increased with the increasing of the roller pitches, but the increments were not significant.
