| Abstract: | Combing with production practice,tensile fracture layer defect of rolled slab of HanSteel slab caster was analyzed and preventive measures were put forward. The center segregation and center porosity could be relieved,the product quality could be improved and the tensile fracture layer defect of rolled slab could be reduced effectively. |
