Limestone for the Steel Industry (was. . . Kline & Culotta's book)

Tony,

Correct for blast furnace production of iron. Both limestone and
dolomite were used. Depended some on the qualities of the ore and
the intended use of the slag.

Mostly correct for open hearth steelmaking. The primary flux was
limestone. But according the the sales manager at MJ Grove in
Stephens City, Va (one of the lime plants below Winchester) and, more
importantly, the 1951 edition of "Making, Shaping and Treating of
Steel", published by US Steel; burnt lime was used to adjust the
level of flux in the open hearth furnace when a greater amount of
lime than provided by the limestone is found to be needed in the
later stages of the heat. This was one of the uses for the
Youngstown containers which were shipped on gons.

For steelmaking, limestone is used, not lime--for those
thinking
of steel industry shipping.
