Real-time heat transfer and solidification model of billet continuous casting of low carbon steel

The continuous casting process is a vital method for producing semi-finished steel products, where the cooling of liquid steel plays a significant role in determining strand quality. This study aims to establish a real-time heat transfer and solidification model applicable in industrial settings. By employing a two-dimensional model that runs online, the system recalculates critical parameters such as shell thickness and billet temperature every 10 seconds. The methodology involved validating the model against measured parameters in an industrial caster, demonstrating its effectiveness in providing accurate predictions and allowing operators to make necessary adjustments. The results reveal substantial improvements in billet quality as the model's implementation leads to a significant reduction in defects, highlighting its applicability in enhancing operational flexibility and control over the casting process. This advancement offers a promising solution to the challenges posed by varying casting conditions and is a crucial step towards optimizing the continuous casting process.
