摘要：

In this work it is described an experimental procedure that led to the development of molten aluminum protecting fluxes for its usage in reverberatory furnaces. Technical, ecological and economic aspects were taken into account. The composition of fluxes was based on the equimolar NaCl-KCl composition, using different fluorides to complete the formulation (NaF, KF, LiF, Na(3)AIF(6)). The different fluxes were tested first at a laboratory scale. Furthermore, the one that showed the best performance regarding the efficiency of recovering of molten metal was tested at industrial trials level. From the laboratory scale test results, the best performance was observed for a formulation containing 90 wt. % NaCl-KCl, plus 10 wt. % Na3AIF6. This formulation was tested at industrial level, reducing the melt losses from 9.46% up to 5.87%. Previously, molten metal losses were evaluated for both laboratory and industrial tests without the use of covering fluxes.
