    Electric Furnace Reduction of Iron Ire Lehigh Preserve

    Electric Furnace Reduction of Iron Ore. Prof. J. W. RICHARDS, of Lehigh University, compared in his paper the reduction process in the blast furnace and in the electric furnace. An outline of the principles of blastfurnace practice is first given. Fuel is needed to provide heat and reducing effect.

    bon iron ore composite based on a lumped system is proposed to examine the reduction behavior of the carbon iron ore composite. This model can be easily used for simulating blast furnaces. Moreover, the optimum structure of the carbon iron ore composite and the influence of the atmosphere on the reduction are analyzed by using the proposed model. 2.

    Blast furnace Simple English Wikipedia, the free ...

    Blast furnace. The process of making iron is simple. Iron ore is basically iron oxide. Iron is made by removing the oxygen. This leaves crude iron called pig iron. This process of removing oxygen is called smelting. Carbon is used in the reduction process, with the ore heated to a high temperature.

    The thick slag layer separates the ironcarbon melt and char from the oxidizing postcombustion products, providing a medium for heat transfer. The exiting gas is then used to preheat and prereduce the iron ore feed materials. The DIOS process uses a series of fluidized bed reactors for preheating and prereduction of iron ore fines.

    Reduction: lronmaking. Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a .

    monoxide (reducing gas) in a vertical furnace which constitutes the reduction reactor and a "heat recovery unit" (2) (3). The manufacturing process is energetically less expensive, if compared to the production of cast iron, as it is not necessary to bring the iron ores to the melting temperature, unlike in the blast furnaces.
