T.Effect of Atmosphere on Scale Evolution in Continuous Casting Process
Abstract
In thin slab continuous casting/hot deformation processes, mold flux and hot charge reheating modify primary as-cast oxide scale structure, making it challenging to remove with high-pressure water descaling process effectively. In this investigation, lab-based trials were conducted on low-carbon pipeline steel grades to mimic these processes. Steel specimens with machined surfaces were reheated in different atmospheres at 1200ºC using an induction furnace with a closed chamber. SEM/EDX analysis of the interfaces revealed insights into the effect of atmosphere and mold flux compositions on scale modification. Thermodynamic analysis was used to understand complex steel oxidation processes in contact with mold fluxes.
