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.

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 …

Melting and Pouring. This module addresses activities in the melt department of a metalcasting facility.

Section through a surface blowhole. The cut-out segment lies on top of the rest of the casting.

Risering Iron Castings. This module identifies the uniqueness of feeding graphitic cast iron alloys. The three ways that risers should be designed for cast iron is explained along with the factors that affect volume change. By the end of this module, you will be able to list unique riser considerations for iron castings. (0.1 CEU)

The foundry process is a sophisticated sequence of operations meticulously orchestrated by cast iron manufacturers to transform raw materials into refined cast iron components. At its core, the foundry process involves a series of distinct stages, each contributing to the seamless creation of durable and precise cast iron elements.
