Abstract

The current intensive development of steelmaking is being impeded by a scarcity of pure scrap. The potential to replace pure scrap with metallized raw materials that are naturally alloyed with vanadium and titanium, such as annealed unfluxed titanomagnetite pellets, could facilitate the achievement of key objectives in metallurgical development, particularly in the smelting of electric steel. The objective of this research was to produce annealed and metallized pellets from titanomagnetite concentrate under laboratory conditions, with the intention of further processing them as a commercial product in a blast furnace or as an intermediate product for the production of hot briquetted iron (HBI). The results demonstrate that pellets derived from titanomagnetite concentrate exhibit sufficient compressive strength (up to 300 kg/pellet) and a degree of metallization exceeding 90%, which aligns with the requirements for electric steelmaking. The suitability of pellets derived from titanomagnetite concentrate for use in both blast furnaces and metallization processes has been corroborated.

利用钛磁铁矿精矿生产退火和金属化颗粒的可能性研究。

纯废钢的稀缺阻碍了当前炼钢业的集约化发展。用钒钛天然合金化的金属化原材料（如退火未熔的钛磁铁矿球团）替代纯废钢的潜力，可促进冶金发展关键目标的实现，特别是在电炉钢冶炼方面。这项研究的目的是在实验室条件下从钛磁铁矿精矿中生产退火和金属化球团，以便在高炉中将其进一步加工成商业产品或作为生产热压铁（HBI）的中间产品。结果表明，从钛磁铁矿精矿中提取的球团表现出足够的抗压强度（高达 300 千克/球团）和超过 90% 的金属化程度，符合电炉炼钢的要求。从钛磁铁矿精矿中提炼出的球团适用于高炉和金属化工艺，这一点已得到证实。

期刊介绍： Materials (ISSN 1996-1944) is an open access journal of related scientific research and technology development. It publishes reviews, regular research papers (articles) and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Materials provides a forum for publishing papers which advance the in-depth understanding of the relationship between the structure, the properties or the functions of all kinds of materials. Chemical syntheses, chemical structures and mechanical, chemical, electronic, magnetic and optical properties and various applications will be considered.
