In electric arc furnace (EAF) steelmaking, the decarburization rate plays a decisive role in determining melting time, refining efficiency, and overall productivity. For high-quality steel grades, increasing carbon input is often necessary to meet chemical composition requirements. Under such conditions, accelerating decarburization becomes the key to shortening the steelmaking cycle…

In electric arc furnace (EAF) steelmaking, a violent boiling accident refers to an abnormal and hazardous process event caused by a sudden and intense acceleration of the decarburization reaction. When this occurs, molten steel, slag, and furnace gas may violently erupt from the furnace, leading to equipment damage, serious safety risks…

In Electric Arc Furnace (EAF) steelmaking, Direct Reduced Iron (DRI) is often considered a supplementary charge material when scrap availability is limited. However, in practical operation, the use of DRI imposes strict requirements on raw material quality, charging practice, process control, and plant management. For many small- and medium-sized EAF…

In Electric Arc Furnace (EAF) steelmaking, the consumption of metallic charge materials and alloys has a direct impact on production cost, metal yield, and operational stability. This article focuses on where steel scrap and alloy losses occur during EAF steelmaking and how these losses can be practically reduced, based on…

In electric arc furnace (EAF) steelmaking, the oxidation stage plays a vital role in determining steel cleanliness, refining efficiency, and overall metallurgical quality. During this stage, decarburization, dephosphorization, and desulfurization are carried out through controlled oxidation reactions, slag formation, and bath agitation, enabling effective gas removal, inclusion flotation, and chemical…

In Electric Arc Furnace (EAF) steelmaking, the oxidation period plays a critical role in decarburization, dephosphorization, and the improvement of molten steel cleanliness. In a previous article, different oxidation methods used during the EAF oxidation period—namely oxidation by adding oxidizing agents, oxygen blowing, and the combined oxidation method—were systematically introduced.…
