ZL104是工业上广泛使用的Al-Si 系铸造铝合金。熔炼中通常用Al-Mn 中间合金调整ZL104的Mn 含量。Al-Mn 中间合金是由纯A1和金属Mn 直接熔制而得,用此中间合金调整成分时,成本较高,还因带入纯铝而影响其他成分的精确控制。我们用ZL104合金的回炉料熔制Al-Si-Mn 中间合金取得较好的效果。
ZL104 is widely used in industry Al-Si series cast aluminum. Melting is usually used Al-Mn master alloy to adjust the Mn content of ZL104. The Al-Mn master alloy is obtained by direct melting of pure Al and metallic Mn. With this master alloy, the cost is high when adjusting the composition, and the precise control of other components due to the introduction of pure aluminum. We use ZL104 alloy back to melt Al-Si-Mn master alloy to obtain better results.
