Optimization of the Steel Casting Process Parameters to Control the Longitudinal Facial Crack (LFC) Defect Appearance

Abstract

: The principal aim of this research is to meticulously detect and comprehend the reasons behind the longitudinal facial crack (LFC) defect during the casting of low-carbon, low-manganese flat steel products. The overarching goal is to mitigate the likelihood of the defect occurring by optimizing key process parameters. Even seemingly minor defects are considered unfavorable in the final product due to the substantial manufacturing losses entailing economic repercussions. The research employs a diverse array of techniques, including the utilization of a scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDX), potentiodynamic polarization curve measurements, and electrochemical impedance spectroscopy
