The operating conditions during the continuous casting process have a great effect on the microstructure of slab solidification,including primary and secondary dendritic arm spacing.On the basis of the analysis of available work,a revised expression for describing secondary dendritic arm spacing during solidification of slab continuous casting was presented,and the relation between the ratio of primary dendritic arm spacing to secondary dendritic arm spacing and the cooling rate was obtained.
