用电解铝液生产铝合金扁铸锭的熔体净化工艺

Melt purification in the course of producing aluminum alloy slab by using electrolytic aluminum melt

针对电解铝液具有温度高、夹杂物多、空气含量高等特点,用电解铝液直接生产铝合金扁铸锭时,采取熔体预处理、两次炉内精炼和炉外在线除气、除渣,对熔体进行净化处理,可以获得纯洁度高的铝合金熔体。

While directly producing aluminum alloy slab by using the electrolytic aluminum melt, we can produce the aluminum al-loy melt with high purity through melt purification treatment like melt pretreatment, twice refinement in furnace, online degassing and skimming out of furnace, according to such characteristics of electrolytic aluminum melt as high temperature, impurities, and air content, etc.
