童为硕, 李晶, 闫威. Effect of Continuous Casting Parameters on Center Carbon Segregation of SWRH82B Steel 160mm x 160mm Billet[J]. Special Steel, 2018, 39(4): 38-42.DOI:
The effect of continuous casting process parameters including M-EMS stirring frequency
casting speed
superheat and secondary cooling water ratio on the center carbon segregation of SWRH82B billet were investigated. The results indicated that low center carbon segregation index could be obtained in lower M-EMS stirring frequency with constant stirring current 300 A
center carbon segregation could be improved by increasing secondary cooling water ratio
but it would get worse with the further increase of secondary cooling water ratio; secondary cooling water ratio of 0. 75 L/kg was suitable for casting speed of 1.8m/min while 0. 80 L/kg was proper for 1. 9 m/min. In addition
superheat between 20 ~ 30 °C had negligible effect on the carbon center segregation.
