Iron And Steel Production
lance with highpressure nitrogen. The process duration varies with the injection rate, hot metal chemistry, and desired final sulfur content, and is in the range of 5 to 30 minutes. Steelmaking Process — Basic Oxygen Furnaces In the basic oxygen process (BOP), molten iron from a blast furnace and iron scrap are refined
The future of steelmaking
The majority of European steel (60%) is made via the primary route. It involves processing iron ore to produce iron sinter or pellets, and then melting these in a blast furnace (BF) with coke to make pig iron. This is processed in a basic oxygen furnace (BOF) to create steel. The rest of Europe's steel comes from the secondary route.

CO 2 abatement in the iron and steel industry
The iron and steel industry is the second largest industrial user of energy, consuming 616 Mtoe ( EJ) in 2007 (IEA, 2010b), and is the largest industrial source of direct CO 2emissions ( Gt in 2007). Overall, iron and steel production accounts for around 20% of
Iron and steel industry report | Deloitte CIS | Manufacturing
Global iron and steel market Production. Over the last 35 years, the iron and steel industry has seen significant changes. In 1980 716 mln tonnes of steel was produced and the following countries were among the leaders: USSR (21% of global steel production), Japan (16%), USA (14%), Germany (6%), China (5%), Italy (4%), France and Poland (3%), Canada and Brazil (2%).
Metal processing
This will strengthen the metal, making it harder to deform. This process is known as cold working. At higher temperatures the disloions can rearrange, so little strengthening occurs. You can try this with a paper clip. Unbend the paper clip and bend one of the straight sections back and forth several times.
Direct reduced iron process
21/06/2018 · 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.

GALVANIZING
Galvanizing is a process for rustproofing iron and steel by the appliion of a zinc coating. Three of the mostused processes for applying zinc to iron and steel are hotdip galvanizing, electrogalvanizing, and zinc spraying. Most products are coated using the hotdip process. It involves immersing steel into a bath of molten zinc,
