In case of high speed casting, the big mold level fluctuation caused by slab bulging occurred. This phenomenon can not be explained by the steady state bulging model, so we made new bulging model considering slab movement and carried out high speed casting test using pilot plant. The results are as follows. (1) We found the critical casting speed occurred mold level fluctuation caused by slab bulging. (2) In case of under the critical casting speed, slab bulging deformations between the support rolls were kept constant because of shell deformations fell in the range of elasticity. (3) In case of over the critical casting speed, slab bulging deformations between the support rolls were changed with slab movement because of shell deformations increased and fell in the range of plasticity. Change of slab deformations contributed to big mold level fluctuation.
