Abstract

High nitrogen steel has been widely explored and developed due to their unique properties. At present, most of the references on high nitrogen steel powders prepared via gas atomization mainly focus on their initial and secondary crushing. The research on the enhanced crushing process caused by the “nitrogen escape” inside the high nitrogen molten steel is rare. In this paper, the enhanced crushing process of high nitrogen steel molten droplet is investigated based on the theoretical calculation and numerical simulation, which reveals the enhanced crushing mechanism of nitrogen-containing droplets in the process of preparing high nitrogen steel powders by atomization method.

Keywords

nitrogen steel; atomized molten droplets; enhanced crushing; theoretical calculation; numerical simulation
