Abstract
Research has been conducted to evaluate the effectiveness of fluxes Ecoraf Ri Flux, Ecoraf F‑1, Foundry EL NA/4, Pyrotek Promag SI, and Hoesch dursalit LM14 in purifying aluminum alloy 1580 from hydrogen, sodium and calcium. For all fluxes, the chemical and granulometric compositions, melting point ranges, hygroscopic and crystallization moisture contents, values of density in the bulk, compacted and molten states, dynamic viscosity and volatility were determined. The effectiveness of using fluxes to purify alloy 1580 from sodium, calcium and hydrogen has been studied. It was established that based on their effect on reducing the content of sodium, calcium and hydrogen in alloy 1580, fluxes can be arranged in the order of decreasing refining ability as follows: Foundry EL NA/4, Pyrotek Promag SI, Hoesch dursalit LM14, Ekoraf F‑1, and Ekoraf Ri Flux.
