INTEGRATED LADLE TREATMENT OF 40HN3MF STEEL USING FESIAL AND FEMN FOR METALLURGICAL ROLLERS

Аннотация

This paper is a review and deals with the study of manufacturing rollers for met-allurgical furnaces with improved performance characteristics. The main attention is paid to complex extra-furnace treatment aimed at improving the mechanical and thermal properties of materials. The study includes the analysis of existing steels and technological approaches. Steel 40HN3МF was selected as the main ob-ject of study.

The chemical composition was optimized using the ThermoCalc software pack-age, where the silicon and aluminum content was varied. The effect of FeSiAl and FeMn deoxidizers was studied to increase strength and heat resistance of materi-als. The work uses literature data that reflect modern trends in the development of steels for metallurgical equipment.

The results obtained allowed formulating recommendations for improving the structure and performance characteristics of metallurgical furnace rollers.
