The Mill Products Division is equipped with an annealing furnace
that has a hot zone of eighty feet in length. The cooling zone is
approximately one hundred feet. It is an open fired continuous roller
hearth furnace. There is no protective atmosphere. This furnace
can accommodate bars up to thirty nine feet in length.
The annealing
cycle that we use provides a mill anneal, or an anneal for machinability.
The resulting structure demonstrates the presence of lamellar pearlite
as well as a spheroidization. However, neither of these structures
can be considered predominant.
