A concentric solidification technique was employed to simulate the segregation of alloying elements that occur during solidification at the centreline of continuously cast steel. Microstructural development of low carbon steel upon solidification has been observed in situ in a laser-scanning confocal microscope. Sulphide precipitates that formed in the last remaining liquid were identified, and evidence is provided that segregation occurring at the centreline of steel slabs can reasonably be simulated by the use of the concentric solidification technique.
采用同心凝固技术来模拟连铸钢中心线凝固过程中合金元素的偏析。利用激光扫描共聚焦显微镜对低碳钢凝固过程中的微观组织演变进行了原位观察。识别出在最后剩余液体中形成的硫化物析出物，并提供证据表明，使用同心凝固技术可以合理地模拟钢坯中心线处发生的偏析。
