Measurement of the Solidified Shell Thickness in the Secondary Cooling Zone of Continuous Casting of Bloom

The solidified shell thickness of bloom near the final stage of solidification in the secondary cooling zone on Pangang No.2 continuous bloom caster was measured,by use of the pin-shooting method.On the basis, the relationship between the solidified shell thickness,the final stage of solidification of bloom and casting speed,secondary cooling intensity wag obtained.The research results have provided the important basis for optimizing continuous casting process,controlling the final stage of solidification and establishing reasonable process parameters of soft reduction.
