It’s the mid-1980s. An Electric Arc Furnace being tapped of its 15-ton “heat” (melted batch) of gray iron, into a ladle in the pit, attached to an overhead crane, which will transport it a short distance to an 83-ton-capacity Channel-type Holding Furnace. The iron is at 2800 degrees Fahrenheit. Iron from the holding furnace will be transferred into 3000-pound pouring ladles, and taken to one of three molding units to produce castings for John Deere Tractors and, for a few years, engine blocks for General Motors’ Pontiac Division.
