delivery systems. The Neeland system remained operational until<br />
blast furnace number 1 was retired in 1982. Although the Neeland<br />
design represented a breakthrough in raw materials delivery<br />
technology at the blast furnace, it was adapted more widely in<br />
Europe than in America. American blast furnace plants more<br />
frequently utilized the skip car delivery system developed<br />
shortly after the Neeland process. One of the most widely used<br />
American skip car delivery systems, the McKee system, was<br />
represented at Duquesne blast furnaces numbers 3 and 4. The Mohr<br />
designed system at blast furnace number 6 represented a major<br />
upgrading of the raw materials delivery systems developed by<br />
Neeland and McKee. Its computer controlled system was able to<br />
deliver a larger amount of raw materials from the stockhouse to<br />
the furnace in a more accurate, regular, and efficient manner. 13<br />
