Experimental Study of non metallic inclu

In recent years, the steel industry has seen increasing demands for higher product quality, which necessitates an in-depth understanding of non-metallic inclusions that could compromise steel reliability. This study specifically examines the behavior of non-metallic inclusions in the tundish during the continuous casting process of steel. The methodology involved collecting steel samples from various stages: before casting, during casting using the MISS sampler, and after casting. Analysis was conducted using scanning electron microscopy coupled with energy dispersive spectroscopy (SEM/EDS) to categorize the inclusions into four main groups based on their composition: slag, deoxidation products, refractory material, and others. Results indicate that two primary inclusion groups—slag and deoxidation products—were prevalent. Additionally, inclusions formed through interactions with the refractory lining were also detected. The study highlights the complexity of inclusions in the tundish and elucidates the interactions occurring between molten steel, cover powder, and tundish linings, emphasizing the necessity of controlling these interactions to enhance steel quality during manufacturing.
