Bulging of 7~8 mm appeared at the narrow side during casting 300 mm thick 16Mn slabs with 3# caster of Chongqing Iron and steel Company.Problems during casting were identified,such as weak cooling intensity of mold especially at narrow side,too small taper at the narrow side and taper change of narrow side foot roller.After optimizing the structure of narrow side foot roller,taper of mold,alignment of copper plate and narrow side foot roller and secondary cooling of narrow side foot roller,the mold was brought to normal operation.Operating practice indicated that the greatest taper change of the improved mold was merely 0.5 mm and bulging at narrow side smaller than 2 mm.
