摘　　要：气隙阻碍铸坯与结晶器之间进行热传递,影响连铸生产效率和铸坯质量,对水平连铸结晶器内气隙产生的原因、过程进行了较为详细的叙述,同时分析了影响气隙产生和分布的四个因素:金属液静压力、坯壳厚度(铸坯收缩)、结晶器冷却情况和铸坯自重。The air gap prevents heat transmission from casting to crystallizer-mould that would be unfavourable to the productivity and the casting quality. The reason causing air gap in the crystallizer-mould used in continuous casting process and its formation process was described in detail, and four factors affecting the formation and distribution of the air gap was analyzed including： the static pressure of molten metal, casting thickness （contraction of the casting）, cooling condition of the crystallizer-mould, and the weight of the casting itself.
