prior treatment of ore blast furnace

Blast furnace - WikipediaBlast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide to elemental iron mixed with carbon. The blast furnace operates as a countercurrent exchange process whereas a bloomery does not.UDC 669 . 162 . 263 Improvement of Blast Furnace Reaction ...consist of four heating furnaces that preheat the gas to the temperature of the upper cohesive zone of a blast furnace (1,200℃) and complete the reduction of ore and 10 heat-insulating furnaces that make the re-actions and heat transfer at temperatures lower than the above tem-perature proceed in an adiabatic system.

One case is the experimental low shaft iron smelting furnace at Liége (Belgium) which was to produce iron from briquettes of ore and coal (which could not survive passage through a high furnace).Blast Furnace Operation - an overview | .Within the blast furnace, metallurgical coke is subject to a complex combination of thermal treatment, mechanical action, and chemical reaction with various gases, vapors, and liquids. The behavior of coke in this environment is a function primarily of the physical structure of .

Former blast furnace in Port of Sagunt, Valencia, Spain. A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.
