Centerline Segregation of Continuously Cast Slabs Influence on Microstructure and Fracture Morphology
คำสำคัญ:

Metallurgical reasons are sought to explain a centerline segregation consisting of additives and impurities in continuously cast slabs of low carbon steel. The influence of segregation on the microstructure and fracture surface Morphology of specimens cut out from the center of the slab was analyzed. The accumulation of sulphidic inclusions and liquations in the center zone of the slab is a typical sign of the centerline segregation. Carbon segregation was observed together with surface active additives (Sn, Sb, As) into the center of the slab with ferrite-pearlite microstructure and different grains in size and shape.
