N2 - The article presents a study on the effectiveness of using the complex alloy Fe-Si-Mn-Al for steel deoxidation. The experiments conducted demonstrated the high deoxidizing capacity of this alloy, as evidenced by significant levels of extraction of alloying elements: silicon (75–85%), manganese (80–87%), and aluminum (60– 70%). The study showed that steel deoxidized with the complex alloy has a 25–30% reduction in non-metallic inclusions compared to samples treated with traditional deoxidizers. This leads to improved metal purity and enhances mechanical properties, with an average hardness of the samples at 27 HRc, which is 1.5–2 units higher than that of traditionally deoxidized steels. The use of the complex alloy also reduces production costs by 10–15%, due to the efficient utilization of low-grade manganese ores and high-ash coals. The study results confirm the feasibility of using the complex alloy Fe-Si-Mn-Al as a promising deoxidizer for improving steel quality and optimizing production processes.
