Производство низкоуглеродистого феррохрома неизбежно сопровождается образованием значительных объемов шлаков, ключевой особенностью которых является их способность к самопроизвольному распаду (дезинтеграции) при охлаждении и воздействии атмосферных факторов. Это явление обусловлено полиморфными превращениями β-дикальциевого силиката (C2S) в γ -модификацию, сопровождающимися увеличением объема. Данная уникальная характеристика, с одной стороны, создает вызовы в управлении отходами, с другой – открывает широкие возможности для их эффективной и экономически выгодной утилизации без необходимости дорогостоящего измельчения. Настоящая обзорная статья представляет собой систематический анализ и обобщение современных высокоэффективных технологий мирового уровня по применению самораспадающихся шлаков производства низкоуглеродистого феррохрома. Особое внимание уделяется их использованию в производстве строительных материалов (цементы, бетоны, вяжущие), сорбентов для водоочистки, мелиорантов для сельского хозяйства, а также в дорожном строительстве. В данной работе проведен литературный обзор пятидесяти семи источников, опубликованных за последние десять лет и содержащих описание наиболее эффективных технологий применения самораспадающихся шлаков производства низкоуглеродистого феррохрома.Целью статьи является демонстрация потенциала этих шлаков как ценного вторичного сырья, способствующего снижению экологической нагрузки, повышению ресурсоэффективности ферросплавного производства и развитию принципов циркулярной экономики.

The production of low-carbon ferrochrome is inevitably accompanied by the formation of significant volumes of slags, the key feature of which is their ability to spontaneously disintegrate upon cooling and exposure to atmospheric factors. This phenomenon is caused by polymorphic transformations of β-dicalcium silicate (C2S) into the γ-modification, accompanied by an increase in volume. This unique characteristic, on the one hand, creates challenges in waste management, on the other hand, it opens up wide opportunities for their efficient and cost-effective disposal without the need for expensive crushing. This review article is a systematic analysis and generalization of modern high-performance world-class technologies for the use of self-decaying slags produced by low-carbon ferrochrome. Special attention is paid to their use in the production of building materials (cements, concretes, binders), sorbents for water treatment, ameliorants for agriculture, as well as in road construction. This paper provides a literary review of fifty-seven sources published over the past ten years describing the most effective technologies for the use of self-decaying slags for the production of low-carbon ferrochrome.The purpose of the article is to demonstrate the potential of these slags as valuable secondary raw materials that contribute to reducing the environmental burden, increasing the resource efficiency of ferroalloy production and developing the principles of circular economy.
