Keywords: iron, coal, direct reduction, reduction smelting, main processes, reduction. 1. Introduction The processes that produce iron by reduction of iron ore below the melting point of the iron produced are generally classified as direct reduction processes, and the product is referred to as direct reduced iron. The processes that produce molten
Hydrogen as a Clean Alternative in the Iron and Steel ...
· Multinational steel production company ArcelorMittal is taking steps to reduce its carbon emissions by outfitting a production plant to use hydrogen for iron ore reduction. ArcelorMittal plans to partner with the University of Freiberg to test a hydrogen procedure at .
Decarbonization in steel | McKinsey
· While integrated players produce steel from iron ore and need coal as a reductant, EAF producers use steel scrap or direct reduced iron (DRI) as their main raw material. As the predominant production method in Europe is the conventional, coaldependent BF/BOF process, the need to assess alternative breakthrough technologies to reduce carbon dioxide emissions is high.
Direct reduced iron process
· Direct reduced iron (DRI) process. In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the socalled direct reduced iron (DRI) process (secondary route).The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.
How steelmaking may go carbonfree—by dropping its ...
· The furnaces that transform raw iron ore into finished steel consume vast amounts of coal, making the steel industry a major producer of carbon emissions. But new manufacturing methods—including biochar, hydrogenbased technologies, and "molten oxide electrolysis," to name just a few—may mean that a lot less coal will be burned in the future.
How hydrogen could change the face of steel production as ...
· The production of pig iron, which is later made into crude steel, uses iron ore as a basic material together with what is referred to as a reducing agent, which removes oxygen from the iron ore. Traditional pig iron manufacturing processes usually use coke as a reducing agent.
ENVIRONMENTAL
the main environmentally related issues involved in the process of producing liquid steel from iron ore by the direct reduction route. The report was examined at the meeting of experts and environmental management guidance for the direct reduction route to steel making was drafted (2). .
Hydrogen in steel production: what is happening in Europe ...
· Iron ore is reduced with hydrogen while in a solid state, hence the name direct reduction, to produce direct reduced iron (DRI) called sponge iron. Sponge iron is then fed into an EAF, where electrodes generate a current to melt the sponge iron to produce steel. Some carbon is needed so that steel can be produced.

Steel making process – ArcelorMittal . Sponge is an intermediate product, which is produced from iron ore by means of direct reduction (= DRI or directly reduced iron) and that is then further reduced...
Decarbonization challenge for steel
produce steel from iron ore and need coal as a reductant, EAF producers use steel scrap or direct reduced iron (DRI) as their main raw material. As the predominant production method in Europe is the conventional, coaldependent BF/BOF process, the need to assess alternative breakthrough technologies to reduce carbon dioxide emissions is high.
An Overview of Steelmaking Process ...
The first metallurgical step involved in this process is to reduce iron ore to metallic iron in a blast furnace, using coke as both a fuel and reducing agent. The produced metallic iron contains a relatively high proportion of carbon (4%) and it is passed to the steelmaking process in the form of liquid at approximately 1450 C, called as 'hot metal'.
Reduction of Iron Oxides with Hydrogen—A Review ...
During reduction of a porous iron ore particle, the following process steps occur: 19, 2224 mass transfer of the gaseous species (reducing gases H 2 and CO) from the gas stream through the laminar layer of the oxide to the interface; diffusion through macro and micropores to the oxide interface; adsorption at the oxide interface; oxygen removal via phase boundary reaction—formation of H 2 ...
