| Abstract: | Through composition check,metallographical test and energy dispersion spectrometry for the cracked part of slabs,it was found out that the reason why slab cracked is the collective action of longitudinal crack,inner crack and heat stress.Avoidance of longitudinal crack production and strict slab quality management are the effective preventing measures of slab crack. |
