It reduced capital cost of the plants and smelting time, and increased labor productivity. Between 1920 and 2000, labor requirements in the industry decreased by a factor of 1,000, from more than 3 man-hours per metric ton to just 0.003. [3] By 2000 the basic oxygen furnace accounted for 60% of global steel output. [3]
The UF 4 was removed from the third furnace and conveyed to a packaging station where the product was packaged in 10-gallon pails for use in the Metal Plant, or in 5-ton containers for shipment to the cascades. The off-gases containing water vapor formed in the reaction and excess hydrofluoric acid was removed from the first furnace and were ...
A reverberatory furnace used coal as a fuel—without first coking the coal as is needed for a blast furnace—and such a furnace could be reused as a 'puddling furnace' later to process pig-iron from a blast furnace; perhaps, as well as capital cost, these were factors in the decision. Foremost in the directors minds was getting iron—even in ...
The blast furnace process is a typical example of a process of reduction of metal from ore with carbon monoxide. Likewise, blast furnace gas collected at the top of blast furnace, still contains some 10% to 30% of carbon monoxide, and is used as fuel on Cowper stoves and on Siemens-Martin furnaces on open hearth steelmaking .
