摘    要:铝合金熔炼与精炼用炉主要有熔炼炉+保温炉炉组和熔保一体炉两种形式。与熔炼炉+保温炉炉组相比,熔保一体炉的建设费用和吨铝能耗低,但熔体质量差,所以对于品质要求高的铝合金熔铸产品可采用熔炼炉+保温炉组生产,对于品质要求低的铝合金熔铸产品可以采用熔保一体炉生产。而且无论是用熔炼炉+保温炉组还是熔保一体炉,当利用电解铝液直接配料生产铝合金熔铸产品时,都应对电解铝液进行除碱处理。

关 键 词:铝合金  熔铸  熔炼炉  保温炉  熔保一体炉  除碱

Abstract:There were two kinds of furnaces for melting and casting of aluminum alloy:smelting furnace+holding furnace unit and integration of melting furnace with holding furnace.Compared with the melting furnace+holding furnace unit,the construction cost and the energy consumption of per ton aluminum of the integration of melting furnace with holding furnace were lower,with poor melt quality.Therefore,for high-quality aluminum alloy products,melting furnace+holding furnace unit could be used for production,and for aluminum alloy products with low quality requirements,integration of melting furnace with holding furnace could be used.In addition,no matter the melting furnace+holding furnace unit or the integration of melting furnace with holding furnace,when electrolytic aluminum solution was used to produce melting and casting products of aluminum alloy directly,it should be removed alkali.
Keywords:aluminum alloy  melting and casting  melting furnace  holding furnace  integration of melting furnace with holding furnace  remove alkali
