Research on Solid Shell Growth during Continuous Steel Casting

The continuous steel casting process must simultaneously meet the requirements for production performance, quality and safety against breakouts. Knowing thickness of solidified shell, particularly at exit mould, is useful control breakout prevention. Shell difficult to measure during casting; in practice, it predicted by indirect methods models. But after undesired rupture shell leakage liquid steel, possible directly. This article focused on problem growth measurement solid obtained a round block with diameter 410 mm. An original methodology was developed which surface mesh points created from individual scanned parts using 3D laser scanner. Research has shown differences up 6 mm between maximum minimum mould exit. A regression function average time found. results real were further used verification numerical model cooling solidification block.
