<p>A method for refining an aluminium-silicon alloy of eutectic composition from admixtures of iron and titanium consists in melting an aluminium-silicon alloy of eutectic composition together with chromium and manganese, cooling down the obtained melt to a temperature of 590 - 660°C and filtering the cooled melt within said temperature range, the chromium and manganese being used in such quantities that the ratio of their total weight to the total weight of the admixtures of iron and titanium is (0.2 - 1.1): 1, the ratio by weight between the chromium and the manganese being (0.1 - 20): 1.</p> |
