摘　　要：根据异形坯的特点和马钢生产经验,对异形坯连铸的主要工艺特点进行分析,并给出马钢的实际顺行生产参数。认为异形坯连铸关键是成分优化、合适的保护渣、低过热度浇注、合理的二冷制度和比水量,含Nb钢连铸的矫直温度>930℃。The beam blank CC technological parametrs and practical production date of Magang are given.The main process properties for beam blank CC are researched according to BB CC features and production parameters of Magang. The conclusion is that the keys of beam blank CC are the optimum chemical composition, adaptable powder, low superheat, reasonable secondary cooling method and the 900 - 930℃ straightening temperature.
