| Abstract Scope |
Mold flux crystallization plays a crucial role in controlling heat transfer during the continuous casting of steel. This study investigates the crystallization behavior of a simulated mold flux (67CaSiO3–33Li2SiO3) under periodic temperature fluctuations using a custom-built Hot-Thermocouple device. Real-time observations revealed that temperature cycling significantly accelerates crystallization compared to isothermal conditions. Increasing the amplitude of thermal fluctuation reduced crystallization time, primarily due to enhanced nucleation rates, while crystal growth rates remained relatively unaffected. Optical microscopy confirmed the presence of spherical crystal morphologies, indicating diffusion-controlled growth. These findings suggest that controlling temperature fluctuation parameters—especially amplitude—can effectively promote crystallization without altering flux composition. This approach offers a promising strategy for optimizing solidification behavior and improving casting efficiency. The study contributes to a deeper understanding of dynamic crystallization mechanisms and supports the development of advanced thermal control techniques in the steel manufacturing industry. |
