一、铝硅合金熔炼时熔渣的来源 在铝合金熔炼过程中,熔渣的来源主要有以下几方面: 1.金属炉料所带入的难熔杂质。由于这些杂质在铝合金熔炼温度(一般为850℃以下)下呈固态,因此它们沉入液底或浮在液面。 2.铝液的氧化:铝的氧化物熔点远高于铝液的熔炼温度,使其以固态存在于合金液中。 3.熔炼设备和熔炼工具所带入的杂质。 其中,铝液的氧化是熔渣的主要来源,
First, the source of slag when smelting aluminum alloy In the aluminum smelting process, the source of slag mainly in the following aspects: 1 refractory impurities brought into the metal charge. Since these impurities are solid at the melting temperature of the aluminum alloy (generally below 850 ° C), they sink to the bottom or float on the surface. 2. Aluminum liquid oxidation: aluminum oxide melting point is much higher than the melting temperature of molten aluminum, so that it exists in the solid state in the alloy liquid. 3. Melting equipment and smelting tools into the impurities. Among them, the liquid aluminum oxidation is the main source of slag,
