在铸造铝合金中,镁是一种主要元素,又是一种易烧损元素。镁的加入量很低,用镁锭直接配料操作很不方便。如何方便而准确的加镁,是铸造铝合金生产的一大问题。我们通过生产试验,找到了一种AlMg40合金,解决了这一问题。该合金生产工艺简单,满足了中间合金的使用要求。 1.原生产中配镁的操作 (1)镁锭锯成小块,搭配使用。这样既浪费材料,又提高成本。 (2)镁锭刨成屑。这样镁氧化严重,对熔炼铝
In casting aluminum, magnesium is a major element, but also a readily burnable element. The amount of magnesium added is very low, with magnesium ingot direct ingredient operation is very inconvenient. How convenient and accurate plus magnesium, aluminum alloy casting is a major issue. We passed the production test to find a AlMg40 alloy, to solve this problem. The alloy production process is simple, to meet the requirements of the use of intermediate alloy. 1. The original production of magnesium operation (1) ingot saw into small pieces, with the use. This will not only waste materials, but also increase costs. (2) Magnesium ingot shaving into chips. This magnesium oxidation serious, on the melting of aluminum
