我厂某些铸件材质系 ZL10和 ZL13铝合金,其化学成分及机械性能如表一、表二。熔化设备为油炉,铸铁坩埚容量100公斤。传统的熔化方法,配制含硅、锰的铝合金时,首先将硅、锰等高熔点的合金元素分别与铝配制成中间合金,然后加入铝液中去。配制中间合金时,要把铝液温度升高到 ,用人工将粒度要求很严格的硅粒、
Some casting materials of our factory are ZL10 and ZL13 aluminum alloy, the chemical composition and mechanical properties are shown in Table 1 and Table II. Melting equipment for the oil furnace, cast iron crucible capacity of 100 kg. Traditional melting method, the preparation of silicon, manganese aluminum alloy, the first silicon, manganese and other high melting point alloying elements with aluminum prepared as the master alloy, and then added to the aluminum solution. Preparation of the master alloy, it is necessary to raise the temperature of molten aluminum, the particle size of the artificial requirements will be very strict silicon tablets,
