For example, technologies have been developed for the reduction of iron ore or steel mill waste oxides to produce a solid direct-reduced iron product. That product could be discharged to a second reactor for melting or cooled and stored for later use.
London — US iron ore miner Cleveland-Cliffs, which is building an HBI plant in Ohio, said it sees a healthy margin between direct reduced iron (DRI) and pig iron, and a move to higher quality iron units for regional electric arc steel mills stoking demand.
direct reduced iron (DRI) Definition ... DRI is consumed primarily by mini steel mills (which can melt only rich sources of metal, such as steel scrap, but not iron ore) to improve the quality of their steel. Since the reduction process consumes prodigious amounts of natural gas, ...
Integrated steel mills incorporating sinter plants, coke ovens, BFs, BOFs, casters, and various pieces of downstream equipment have proven to be cost-effective if massive amounts of steel can be profitably sold, to a large market, but they aren't ideal for every situation.
produce steel from scrap steel, pig iron, or direct reduced iron (DRI) using an electric arc furnace (EAF). The majority of steel produced in the U.S. is from integrated steel mills, although the share of secondary steel mills (or
In electrometallurgy, direct-reduced iron is exclusively used as a source of iron for steelmaking. It is a major and very serious contender for scrap and pig iron. A further DRI twist is provided by its development inextricably linked with that of electric steel production.
Kobe Steel has developed coal-based direct reduction (DR) technologies, the FASTMET, FASTMELT and ITmk3 processes, which reduce carbon composite ... processing steel mill dust generated at the Kakogawa Works. Fig. 3 shows the FASTMET process flow. The
In the gas based plant the reactor, the reduction reaction takes place is a shaft furnace. The shaft furnace works on counter current principle where the iron ore feed material moves downward in the furnace by gravity and gets reduced by the up flowing reducing gases.
The 2,500,000 tons-per-year iron making facility will use direct reduction technology to convert natural gas and iron ore pellets into high quality direct reduced iron ("DRI") used by Nucor's steel mills, along with recycled scrap, in producing numerous high quality steel products such as sheet, plate and special bar quality steel.
The direct reduction process. HBI is the product of reducing iron ore with natural gas. This is called the direct reduction process and is an environmentally-friendly production process; a DRI plant uses natural gas which is more environmentally sound than coke. The reduction process takes place in the reduction tower.
Steele stiff extrusion offers iron & steel mills a proven, scalable agglomeration process to convert mill by-products to feedstock. Our process scales, handling fine, wet materials while using less binder to deliver an engineered end product — for the consistent durability and …
and productive Direct Reduction Technology ... ually innovating the world's most reliable and productive ® Direct Reduction Technology: ... sometimes the cyclic nature of the steel industry can reduce the requirement for a direct reduction plant's full production capacity.
 The present invention relates generally to methods and systems for producing direct reduced iron (DRI). More specifically, the present invention relates to methods and systems for producing DRI and steel mill fuel gas using coke oven gas (COG) and basic oxygen furnace gas (BOFG).
The Association for Iron & Steel Technology (AIST) is a non-profit entity with 17,500 members from more than 70 countries. AIST is recognized as a global leader in networking, education and sustainability programs for advancing iron and steel technology.
Nucor Corporation is made up of over 20,000 teammates whose goal is to 'Take Care of Our Customers.' We are accomplishing this by being the safest, highest quality, lowest cost, most productive and most profitable steel and steel products company in the world.
Most gas-based direct reduction plants are part of integrated steel mini-mills, located adjacent to the electric arc furnace (EAF) steel plant. DRI can be either hot or cold charged to the EAF. Some steel companies ship DRI from their captive direct reduction plants to their remote steel mills and a small volume of DRI is sold to third parties.

Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BF-BOF and Scrap-EAF routes. In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction.
the production of steel in mini-mills, as well as problems with price volatility of scrap has led to a renewed interest in the development of direct reduced iron (DRI), also called
