铝合金的熔炼配料,通常是以铸件要求的化学成分为主要依据,由所需的铝合金量计算中间合金和纯铝的用量,结果是常常需要付出劳动截割铝锭。为使配料方便,可用铝锭(块)重量计算中间合金和铝合金的重量,这往往又造成合金熔炼的过量或不足。而这两种计算的结果都没有明显地反映
Aluminum alloy smelting ingredients, usually based on the chemical composition of the casting as the main basis for calculating the amount of aluminum alloy required by the amount of aluminum alloy and the amount of aluminum, the result is often required labor-cutting aluminum ingot. In order to facilitate the ingredients, aluminum ingots (blocks) can be used to calculate the weight of the middle alloy and aluminum alloy, which often leads to excessive or insufficient smelting alloy. The results of both calculations are not clearly reflected
