Abstract

Abstract: The interaction between titanium slag or vanadium slag formed during smelting vanadium titanomagnetite in the blast furnace-converter process and refractories was analyzed and summarized.The corrosion process and mechanism of refractories for iron and steel smelting by titanium slag and vanadium slag were pointed out,and the occurrence state of variable valence metal elements,such as vanadium,titanium and iron in vanadium-titanium slag was explored.It was proposed that using computer simulation and other auxiliary technologies to analyze the corrosion behavior of refractories by a complex slag system would be the future development direction.

Key words: titanium slag, vanadium slag, refractories, corrosion
