摘　　要：以南阳汉冶特钢400 mm×2 700 mm连铸坯窄面鼓肚为研究对象,结合生产实际,分析了结晶器冷却强度、结晶器锥度、结晶器足辊长度对窄面鼓肚的影响。提出了防止特厚板坯窄面产生鼓肚的措施,有效解决了400 mm特厚板坯窄面鼓肚现象。指导特厚板坯连铸机的改造与连铸生产。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.
