A1

Abstract:

A process for producing an iron-boron-silicon alloy through simple steps with economic advantages, which comprises adding a boron material and a carbonaceous reducing agent to a molten iron placed in a vessel, blowing oxygen into said molten iron to reduce the boron material contained in the molten iron and prepare boron-containing molten metal, continuing blowing of oxygen till the carbon content of the boron-containing molten metal reaches 0.2 wt % or less to decarburize the boron-containing molten iron, and adding at least one of silicon and ferrosilicon to the boron-containing molten iron.
