铝合金精炼一变质综合处理工艺突破了铝合金传统的熔炼工艺,它的工艺操作特点是,采用“压入—复盖”法的精炼-变质一次处理;其工艺过程是:合金熔化升温至精炼一变质综合处理要求的温度后,在合金液中用钟罩压
The refining and metamorphism comprehensive treatment process of aluminum alloy breaks through the traditional smelting process of aluminum alloy. The characteristic of its process operation is that it adopts the process of “press-over-cover” to refine and deteriorate. The process of the process is as follows: After a metamorphic treatment requires a temperature, the bell jar is pressed in the alloy liquid
