BLAST FURNACE, The iron was shaped into iron bars by undergoing a process of heating and, UDC 669 .The figure shows a flowchart of the integrated manufacturing process for iron and steel using the blast furnace and basic oxygen furnace denoted.
Blast furnaces are used continuously and are only shut down when their brick lining needs replacing. As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron.
Blast furnace metallurgy Britannica. Blast furnace, a vertical shaft furnace that produces liquid metals by the reaction of a flow of air introduced under pressure into the bottom of the furnace with a ... are used to produce pig iron from iron ore for subsequent processing into steel, and ...
Internally the blast furnace is considered to consist of five discrete zones, see Fig. 17.2, through which all furnace gases andor liquids must pass.The location, shape and extent of each zone is influenced by the properties of the material layers relative thickness, etc. and by the properties of the materials themselves. These factors interact to determine the flow and distribution of ...
During the operation of blast furnace ironmaking process, different kinds of faults may happen, such as hanging, low stockline and abnormal gas flow. If the faults cannot be detected and identified in time and accurately, it may lead to loss in production rate or even a significant accident.

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 ...
blast furnace processing by center coke charging. The coke layer has a gas-flow resistance smaller by a factor of 10 compared to that of the ore layer and has a high gas-permeability. When a larger amount of coke exists, relatively, at the center of a blast furnace, the high temperature gas, consisting mainly of CO generated at the tuyeres,
Jan 01, 2010 The blast furnace process has auxiliary equipment associated with it. This auxiliary equipment and the gaseous pathways inside a blast furnace process are shown in Fig. 2. The blast furnace process can be briefly described as follows. Iron oxides, flux agents, and metallurgical coke are added to a skip car at the stock house.
