Z106属于铝—硅—铜系合金,其主要化学成分为:Si7.0～8.5％,;Cu1.0～2.0％,Mg、Mn均为0.2～0.6％,其余为铝。它易氧化,吸气倾向大。在天气潮湿,设备条件较差的情况下尤为突出,所浇铸件往往存在严重缩松、夹渣、针孔等缺陷,大型平板件其缺陷更为严重,经常导致废品。对于此问题通常提倡用压力铸造等方法加以解决。怎样才能在地坑炉熔炼的简陋条件下生产合格的大型平板件?85年,我们在造型工艺和熔炼工艺上采取了一些措施,对计数机墙板进行了尝试。85、86两年共生产一百一十块,
Z106 belongs to the aluminum-silicon-copper alloy, and its main chemical components are: Si7.0-8.5%, Cu1.0-2.0%, Mg and Mn are 0.2-0.6%, and the balance is aluminum. It is easy to oxidation, inspiratory tendency. In wet weather, the equipment is particularly poor circumstances, the casting often have serious shrinkage, slag, pinholes and other defects, the more serious defects of large-scale flat-panel, often lead to waste. For this problem is usually promoted by pressure casting and other methods to be solved. How can we produce qualified large-scale flat parts in the humble conditions of pit furnace melting? In 85 years, we took some measures in the molding process and the melting process to try the counting machine wallboard. 85,86 two years produced a total of 110,
