摘　　要：阐述宽板坯高拉速连铸的特点 ,分析了易产生的缺陷类型。This paper describes the characteristics of high-speed wide slab casting and analyzes its common defects. Emphases are laid on analyzing the causes of longitudinal cracks of peritectic steels, the transverse and corner cracks of microalloyed steels containing niobium, vanadium and titanium. In addition,corresponding measures to prevent the above-mentioned defects are also given in the paper.
