Study on the Lining Erosion of Deep Reduction Electric Arc Furnace in Smelting Metallized Pellets Process Produced by Vanadium Titanium Magnetite

The erosion of the lining refractory of the deep reduction electric arc furnace is introduced, and the erosion appears in the process of smelting metallized pelltes produced by vanadium titanium magnetite. It shows that arc erosion, chemical erosion of oxides in slag, slag basicity, as well as joint and crack of brick are the main reasons of the serious erosion of the refractory through the analysis.
