| Abstract Scope |
Temperature uniformity of the solidified shell within a continuous casting mold directly governs solidification homogeneity, thermal stress distribution and corner defect susceptibility. Corners of conventional square molds undergo two dimensional cooling from adjacent sides, which readily yields corner shells featured by low temperature and large thickness. In this work, a fluid flow and heat transfer model is established using ANSYS Fluent for a 160 mm × 160 mm billet. The mold has an effective length of 900 mm and the casting speed is set to 3.0 m/min. As the fillet radius increases from 6 mm to 20 mm, the minimum mold exit temperature rises from approximately 1023 K to 1250 K, while the corner temperature gradient drops from 17750 K/m to 10890 K/m and the corner shell thickness decreases from 20.2 mm to 15.9 mm. Increasing fillet radius mitigates corner concentrated cooling and improves circumferential temperature uniformity, whereas the beneficial effect becomes obviously limited once the radius exceeds 15 mm. |
