12.10 Gray Iron Foundries
12.10.2.4 Casting And Finishing -. Molten iron is tapped into a ladle or directly into molds. In larger, more mechanized foundries, filled molds are conveyed automatically through a cooling tunnel. The molds are then placed on a vibrating grid to shake the mold sand and core sand loose from the casting.

Controlling Molten Iron Chemistry and Metal Fluidity
Increasing pouring temperatures causes many quality issues in the casting process. Things like burn-on and increased shrinkage lead to big problems. The metal's chemistry is important to establishing melt fluidity. Iron develops a eutectic, its lowest melting point, as chemistry nears the 4.3% CE (C and Si percentage calculated in a …
