Abstract

AZ91D magnesium alloy met the ASTM standard was directly prepared from the crude magnesium by melting

alloying and refining the magnesium in line-frequency coreless induction furnace and then holding purification in electric resistant furnace. The effects of ignition proof during melting process

impurities removal and purification as well as temperature control on quality of magnesium alloy were described to optimize smelting-casting parameters of AZ91D alloy directly prepared from crude magnesium. The experimental results verify that the method of directly smelting-casting magnesium alloy from crude magnesium have some advantages

such as easy parameters controlling

short technological process

low loss of metal elements

low energy consumption and environmental pollution

high production efficiency and high product quality as well as low cost.
