The effect of water ratio in secondary cooling zone on billet cooling speed
solidification structure and center carbon segregation index of 0.64% ~ 0.82%C steel 150 mm x 150 mm billet casting with 250A/5Hz electromagnetic stirring has been tested. The results showed that with water ratio in secondary cooling zone increased to 1.55 L/kg from 0.83 L/kg
the primary dendritic aim spacing at the location with distance from billet edge 46 mm decreased to 300 from 380 the average center carbon segregation index decreased to 1.10 from 1.15 and at the sometime the ratio of equiaxial crystal decreased to 40% from 45%
The high secondary cooling intensity is only fit for billets casting.
