摘　　要：对板坯连铸机钢水凝固收缩特点及开口度参数对铸机生产的影响、连铸机开口度参数计算的理论依据进行了系统的分析,济钢板坯连铸机开口度设计生产实践表明,以铸机工况条件、钢种拉速及铸坯实物质量控制为基础,理论结合实践来设计铸机开口度参数的方法是合理实用的,铸坯的内部质量缺陷,特别是中间裂纹、中心偏析控制在了较低水平。This article analyzed the solidification shrinkage characteristics of liquid steel, the influences of the gap parameters on the production of CCM and the basis of the gap calculation and so on. An example of designing practice on the slab CCM in Jinan Steel was given out also. The production practices proved that the method studied is practical and suitable and the internal quality defects especially the cracks and center segregation were controlled in low level.
