| Abstract: | This paper elucidates the use of the cold hardening resin sand in the casting of magnesium alloy, and puts forward several combustion protective ahents and their proportionings in the sand.On the other hand the dispersivity of the sand can be improved by controlling the content of resin, and molding process can be simplified and the cold hardening resin sand can be saved by twin-sand molding, and the precision and smoothness of the casting can be improved as well. |
