Abstract

Ferroalloys are widely used materials to overcome the difficulties encountered in casting steel materials and to improve their mechanical properties. These materials are generally produced with methods that require high cost and energy. In this study, FeMn, one of these alloys, was produced by metallothermic reduction, which is an alternative method. The reduction systems are modeled with the FactSage 7.1 program. In the study, Millscale and Hematite were used as a source of iron, and MnO was used as a source of Manganese. Mg and Al are used as reductants in reduction systems. Millscale used in experimental studies is an iron oxide-rich structure formed during cooling on steel surfaces produced. Recycling of this material is important. In this study, the reduction conditions have been investigated by evaluating the material as a raw material.

Özet

Çelik malzemelerin dökümünde karşılaşılan zorlukların üstesinden gelmek ve mekanik özelliklerini geliştirmek için, ferroalaşımlar yaygın bir biçimde kullanılan malzemelerdir. Bu malzemeler genel olarak yüksek maliyet ve enerji gereksinimi olan yöntemler ile üretilmektedir. Bu çalışmada bu alaşımlardan biri olan FeMn alternatif bir metot olan metalotermik redüksiyon ile üretilmiştir. Redüksiyon sistemleri FactSage 7.1 programı ile modellenmiştir. Çalışmada demir kaynağı olarak Tufal ve Hematit, Manganez kaynağı olarak da MnO kullanılmıştır. Redüksiyon sistemlerinde indirgeyici olarak Mg ve Al kullanılmıştır. Deneysel çalışmalarda kullanılan Tufal üretilmiş çelik yüzeylerde soğuma esnasında oluşan demir oksitçe zengin yapıdır. Bu malzemenin geri dönüşümü önem arz etmektedir. Bu çalışmada malzeme hammadde olarak değerlendirilerek redüksiyon koşulları incelenmiştir.
