Abstract

Abstract

Combined with theoretical analysis, element balance statistics and industrial tests, the trend, distribution and control measures of P in FeV50 smelting process of large-scale tipping furnace were studied. The results show that P₂O₅ brought in by raw materials during FeV50 smelting in large-scale tilting furnace can be fully reduced by metallic aluminum and enter the alloy. Vanadium trioxide and ball-milled iron particles are the main input sources of P, with 85.71% of P entering the finished alloy, 13.41% of P entering the residual alloy and fine powder, and 99.12% of P entering the metal phase. The most effective method to control the P content in FeV50 is the control of P content in vanadium trioxide not exceeding 0.0326% and the replacement of more than 60% of the ball-milled iron particles with steel scraps.
