Abstract

Abstract

In order to calibrate the solidified end position of the 50CrV spring steel billet with 240 mm×240 mm section and determine the reasonable position of electromagnetic stirring at the solidification end, the nail shooting experiment was carried out on the Xianggang billet continuous caster. The results showed that the comprehensive solidification coefficient of the spring steel billet was 26.8 mm/min^1/2. When the casting speed are at 0.8 m/min and 1.0 m/min, respectively, The end positions of solidification are 16.2 m and 19.8 m from the meniscus surface, respectively, and the suitable positions of electromagnetic stirring at the end of solidification are 7.18 m and 8.84 m from the meniscus surface. Based on the verification of the nail test, the solidification heat transfer model was established, and had been used to studied the solidification characteristics of the casting billet under different continuous casting process parameters. The model predication could be used to optimize and correct the existing continuous casting parameters so that the electromagnetic stirring effect at the solidification end could be fully exerted and the central segregation should be reduced, consequently the quality of the casting billet could be improved.
