| Abstract: | Taking the 400 mm special thick slab narrow side bulging as the analytical object， combined with the actual production， analyzed the influence of the cooling intensity of mould， taper at the narrow side， length of narrow side foot roller on the narrow face bulging. To effectively solve the problem， some measures to prevent the slab narrow face bulging were presented to guide the special thick slab casting machine improvement and continuous casting production. |
