Kinetic Research of Boron Oxide Reducing Reaction at Low Temperature

Abstract:

The reducing process of boron-containing slag at low temperature is an important stage of the direct alloying for smelting boron steel. At low temperature boron slag generates mainly solid - solid reaction in the sintering period. The experiments were done on the carbon tube furnace in laboratory, and the effect of slag reaction in different times at 1200°C was researched. The samples were analyzed by XRD after the reaction. The experimental results shown that the reduction rate increased by increasing reducing time. The chemical reducing reaction of boron oxide by ferrosilicon is second-order reaction at solid state.
