Cause and Measures of Transverse Corner Crack in Hull Structural V-Containing Steel CC Slabs
The reasons of transverse corner crack in hull structural steel CC (continuous casting) slab have been analyzed in this paper. The influence of steel-making, continuous casting technics and micro alloy element has been discussed. The improving measures are put forward and better effects have been obtained.
