AUTOMATIC MEASUREMENT OF CENTRELINE SEGREGATION IN CONTINUOUSLY CAST LINE PIPE STEEL SLABS

摘要：

　　Centreline segregation appears as a positive segregation of alloying elements like C,Mn and P in the mid thickness region of continuously cast slabs.It is an intrinsic phenomenon for the casting process and it is almost impossible to mitigate through post processing.Centreline segregation can be harmful to the weldability and integrity of any fabricated steel product,especially line pipe.At present,there is no international consensus on evaluation methods of centreline segregation.A repeatable and objective method for evaluation of centreline segregation is highly desirable for both steelmaking process improvement and also for the prediction of final product performance.
