Special Issue Information

Dear Colleagues,

The steelmaking and ironmaking industries are constantly evolving to meet the demands of a globalized market and increasingly stringent environmental regulations. This Special Issue of Metallurgy Investigation in Nonferrous Metal Smelting focuses on the latest advancements in metallurgical research, process optimization, and material development for both steelmaking and ironmaking. We welcome contributions exploring innovative process technologies, material characterization, and modeling techniques that address key challenges in these industries, including developing efficient and environmentally friendly direct reduction processes for iron ore, optimizing electric arc furnace steelmaking processes for improved energy efficiency and reduced emissions, investigating innovative technologies for refining and alloying steel, exploring new steel grades with enhanced strength and toughness for various applications, developing steels with specific properties, such as high corrosion resistance, high-temperature strength, or enhanced formability, investigating new raw materials and alternative iron sources for sustainable ironmaking, developing predictive models for ironmaking and steelmaking processes to optimize efficiency and reduce costs, and modeling the behavior of different materials during steelmaking and ironmaking processes to improve process control and product quality.

This Special Issue aims to provide a comprehensive overview of the latest research and development activities in the field of steelmaking and ironmaking, fostering collaboration and innovation to address the growing demand for sustainable and high-quality steel production. We encourage submissions from researchers and industry professionals working across the spectrum of steelmaking and ironmaking, including process engineers, metallurgists, material scientists, and environmental specialists.

Titanium metal is primarily produced via the Kroll process, which is characterized by a semi-continuous production flow and a lengthy process cycle, resulting in high production costs. Researchers have explored alternative methods for titanium production, including molten salt electrolysis, such as the Fray–Farthing–Chen (FFC), Ono Suzuki (OS), and University of Science and Technology Beijing (USTB) processes, aiming to achieve more economical production. Among these, the USTB process, a representative of soluble anode electrolysis, has shown significant promise. However, controlling oxygen concentration in titanium produced by soluble anode electrolysis remains a challenge. This study proposes a novel approach to enhance deoxidation efficiency in soluble anode electrolysis for titanium production by introducing yttrium chloride (YCl3) into the molten salt electrolyte. Thermodynamic analysis and experimental validation demonstrate that the theoretical deoxidation limit for titanium can reach below 100 ppm under Y/YOCl/YCl3 equilibrium. We report the successful synthesis of titanium powder with an oxygen concentration of 6000 ppm from titanium-carbon-oxygen solid solution. Under optimized conditions, the purity of the titanium powder reached 99.42%, demonstrating a new approach for producing high-purity titanium. This method, based on soluble anode electrolysis, offers a potential alternative to the conventional Kroll process. The research elucidates the fabrication process and analytical methods for titanium-carbon-oxygen solid solution, and employs a combination of analytical techniques, including XRD, SEM-EDS, and ONH Analyzer, for characterization of the electrolytic product, encompassing phase analysis, microstructure, and oxygen concentration testing.
