摘要：

A new process of directly smelting boron steel from boron-containing pig iron has been established. The starting material boron-containing pig iron was obtained from ludwigite ore, which is very abundant in the eastern area of Liaoning Province of China. The experiment was performed in a medium-frequency induction furnace, and Fe2O3 powder was used as the oxidizing agent. The effects of temperature, addition of Fe2O3, basicity, stirring, and composition of melt on the oxidation of silicon and boron were investigated respectively. The results showed that silicon and boron were oxidized simultaneously and their oxidation ratio exceeded 90% at 1 400 °C. The favorable oxidation temperature of silicon was about 1 300-1 350 deg;C. High oxygen potential of slag and strong stirring enhanced the oxidation of silicon and boron. © 2007 Central Iron and Steel Research Institute.
