| Abstract: | In connection with the actual conditions of JISCO slab caster,the factors affecting the formation of the center cracks in continuous cast steel slabs were investigated and the corresponding countermeasures were put forward.For facility management,it was found that the standard and precision of the use of the continuous caster is confirmed and the pretty condition of the performance for the continuous caster is the foundation to prevent the center cracks of slab.For technological operation,the center cracks is effectively suppressed by control of the superheat degree of molten steel and the content of sulfur and phosphor and the less second cooling intensity. |

| Keywords: | continuous casting slab center cracks superheat degree second cooling intensity |
