OPTIMIZATION OF CONTINUOUS CASTING TECHNOLOGY AT PANZHIHUA IRON AND STEEL CO.

A series of the related techniques for optimization of continuous casting process were used at PHZ Steel,such as improvement of ladle refining and tundish metallurgy for cleaning of molten steel,using compound roll,lower overheating degree casting and casting powder for high speed continuous casting,and optimization of the heat transfer model of secondary cooling zone etc.The production of the slab,the operation rate of the slab continuous caster were increased and the quality of the slab was improved under condition of high speed continuous casting by means of the above techniques
