Abstract
The paper analyses the sticking breakout in slab continuous caster at Hanbao Steelmaking Plant of Hebei Iron and Steel Group Corp.from Oct 2008 to Feb 2011.It analyses the process of sticking breakout through the shell.The reasons of sticking breakout was investigated by studying the performance of powder,the taper and oscillation of mold,the liquid surface wave,the change of cast speed and the casting operation.The preventive measures of the sticking breakout were put forward,which reduced the rate of breakout at Hanbao Steelmaking Plant.
