This investigation discusses the experimental methods to characterize and evaluate the mold flux performance during continuous casting of liquid steel. The mold fluxes are initially characterized by the conventional techniques for particle size, phase identification, phase transformation during the heating process, viscosity, break temperature, and other high-temperature properties. Subsequently, the initial solidification behavior of the peritectic and interstitial free (IF) steel in the presence of respective molten mold flux has been simulated using an in-house designed and developed inverse mold simulator. This simulator takes into account the physical, thermal, and fluid properties of mold flux, liquid steel to be cast, and casting parameters (casting speed, mold oscillation frequency, and stroke length), to assess the performance of liquid steel casting in the continuous caster. A suitable mathematical model has also been developed to predict the transient heat flux and hot face surface temperature of mold at the meniscus level. The current study successfully concludes the importance of a mold simulator along with the conventional characterization techniques to completely evaluate the performance of any mold flux.

使用反向模具模拟器对液态钢连铸用保护剂进行表征和评估

本研究讨论了在钢水连铸过程中表征和评估保护渣性能的实验方法。脱模剂的初始特征在于粒度、相识别、加热过程中的相变、粘度、断裂温度和其他高温特性的常规技术。随后，使用内部设计和开发的反向模具模拟器模拟了包晶和无间隙 (IF) 钢在各自熔融保护渣存在下的初始凝固行为。该模拟器考虑了保护渣的物理、热和流体特性、要铸造的钢水和铸造参数（铸造速度、结晶器振动频率和冲程长度），用于评估连铸机中液态钢铸造的性能。还开发了一个合适的数学模型来预测弯液面水平模具的瞬态热通量和热面表面温度。目前的研究成功地总结了模具模拟器以及传统表征技术对全面评估任何模具助熔剂性能的重要性。
