Why Chinese steelmakers are using less scrap in …
10.07.2019 · Higher scrap use increases productivity and lowers costs The usage of scrap in integrated carbon steelmaking has traditionally been limited to that charged into the basic oxygen furnace (BOF) before the hot metal is added. Other than serving as a necessary coolant during steelmaking, the respective prices of hot metal and scrap, the latter ...
Why is scrap used in a blast furnace? - Quora
Ferrous scrap (steel or iron scrap) is NOT used in a blast furnace. It has been tried: shredded scrap has been added to the iron ore burden of a blast furnace, but no improvement in “hot metal” (steelmaker’s jargon for liquid iron) production resulted.

Use of DRI and HBI in steel making plants
The Blast Furnace (BF) plants were built for the production of large amounts of steel. The beginning of a melting metallurgical process is composed of the reduction of iron ore. In the BF, Cast Iron is produced and after that, by blowing oxygen in the converter, it is turned into the steel. The Direct Reduced Iron (DRI) is usually used in its briquette form (Hot Briquetted Iron (HBI)) for ...

Direct reduced iron - Wikipedia
07.10.2005 · Unlike blast furnace pig iron, which is almost pure metal, DRI contains some siliceous gangue (if made from scrap, not from new iron from direct reduced iron with natural gas), which needs to be removed in the steel-making process.
How is Steel Produced? | World Coal Association
28.04.2015 · The most commonly applied process for steel-making is the integrated steel-making process via the Blast Furnace – Basic Oxygen Furnace. In the basic oxygen furnace, the iron is combined with varying amounts of steel scrap (less than 30%) and small amounts of flux.
Steel - Basic oxygen steelmaking | Britannica
Steel - Steel - Basic oxygen steelmaking: More than half the world’s steel is produced in the basic oxygen process (BOP), which uses pure oxygen to convert a charge of liquid blast-furnace iron and scrap into steel. The basic oxygen furnace (BOF) is a refractory-lined, tiltable converter into which a vertically movable, water-cooled lance is inserted to blow oxygen through nozzles at ...
How Do I Compare Electric Arc Furnaces and Blast …
A blast furnace is used to make steel from liquid iron, while an electric arc furnace is used to make steel from scrap material. Electric arc furnaces use two different types of electrical currents to create heat. Blast furnaces force air into the bottom of the furnace into a heated stove area. The heat from the blast furnaces stove area converts the forced air into heated air to melt metal.

The basic oxygen furnace is the process in which a mixture of scrap (25 to 30 percent) and hot metal (75 to 70 percent) from the blast furnace is exposed to oxygen blown at a high velocity into the bath. Such furnaces may be top-blown, bottom- blown, or a combination of the two.
Blast Furnace - an overview | ScienceDirect Topics
Blast furnace gases contain close to 30% CO 2, after full combustion of the CO fraction, while the overall flue gas stream from an integrated steel mill is ∼15% CO 2.The same CO 2 capture options introduced above for power-generation plant can therefore also be applied to a steel mill:. CO 2 capture from the overall flue gas stream. Firing the blast furnace with oxygen rather than air ...
