Jun 21, 2018 Combustion process. The iron in the processed ores must be dissolved out by chemical processes. This requires an element that binds oxygen more strongly than iron. This is exactly what carbon can do as a reducing agent.The carbon is fed to the blast furnace in the form of coke pyrolyzed coal from the coking plant.At sufficiently high temperatures, the carbon can participate directly in the ...
Jul 23, 2021 Abstract The urgent problem regarding the depletion of mineral resources in ferrous metallurgy can be efficiently solved by a complex reuse of man-caused waste products. Such wastes are mostly presented by electric arc furnace EAF slag and ladle furnace LF slag. These two kinds of slag are not completely utilized. The residues of these slags are stored in dumps of enterprises and thereby ...

Mar 24, 2017 I believe, however, that most blast-furnace plants would hesitate to install equipment for this pressure and superheat. If the blower is figured on 150 lb. steam pressure and 28 in. vacuum, which I believe is more in accordance with present blast-furnace practice, the calculation appears as follows Assume 12 lb. of steam per shaft horsepower.

Mar 30, 2021 Energy costs account for about 11 of the cost of producing steel for the blast furnace BOF method, while it is 8 for the EAF method. The second largest energy user in a steel plant is reheating furnaces. This energy is supplied primarily by natural gas, and where available, coke oven and blast furnace gas.
May 21, 2020 A blast furnace is a special type of cylindrical furnace, which is basically used for the purpose of smelting. So, the industrial metals can be extracted from their ores like iron, pig iron, or copper. The word blast gives the idea of combustion air which is forcefully supplied or produced to the atmospheric pressure above.
Jan 10, 2016 Initially primitive heat exchanger type hot blast equipment was built on top of the BF and simply used the waste heat to preheat the cold blast running through the cast iron pipes. Then the BF gas from the furnace top was conveyed to the hot blast oven where it was burned to generate heat.
Blast furnaces were first built and employed in the creation of iron in China in the first century AD. It is believed that the very first of these evolved from earlier furnaces which were used in the melting of bronze in the 4th and 5th centuries BC, and the same basic structure of those first
The iron from the blast furnace is then further refined and converted to steel in the basic oxygen furnace BOF. Depending on the plant, 20-30 of scrap is added to this process, primarily to regulate the temperature. In the Electric Arc Furnace route EAF 100 scrap used. This is the remelting of steel without the use of primary raw materials.
