The metal temperature is the most important factor to determine a controlled level of the slag in the furnace. If the metal temperature exceeds 780 oC, the rate of formation of slag increases dramatically, as shown in Figure 2. Figure 2 - Dependence of the rate of formation of slag of aluminum melt temperature. Stirring aluminum melt

A. Slag is the glass-like by-product left over after a desired metal has been separated from its raw ore. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of the smelting, and minimizing any re-oxidation of the final liquid metal product before the molten metal is removed from the furnace and used

In this study, mathematical model of vanadium transfer from metal to slag was formulated and the rates of vanadium extraction of hot metal with basic slag were investigated. The results indicated that the apparent vanadium extraction rate constant, k p , were in the range of 1.33∼9.07×10– 4 g/ (cm 3 ·s).

Slag is also called molten slag. The melt that floats on the surface of liquid substances such as metals during the pyrometallurgical process is composed mainly of oxides (silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide), and often contains sulfides and a small amount of metal.
