wrought iron - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online. Wrought iron is produced through a process involving refining pig iron, puddling to form balls, shingling to remove slag, and rolling into bars. It has low carbon content around 0.15% which makes it soft and easy to forge.
machined iron castings. Metal foundries produce molten iron by melting scrap iron, pig iron, and scrap steel in a traditional coke-fired cupola furnace, or in electric-induction or electric-arc furnaces. Molten iron is refined by adding alloying metals into either the furnace or a ladle. It is then moved to a pouring station for pouring into molds.
9. Uses Of Iron In the Haber - Bosch Process, Iron catalysts are used for commercial production of ammonia.

Defects in Casting. Manufacture of Cast-Iron: The cast-iron is manufactured by re-melting pig-iron with coke and limestone. This re-melting is done in a furnace known as the cupola furnace. …
2. Steel is an alloy of Iron and Carbon(0.02% - 2.14%) and alloying materials like Mn,Cr,Ni,W. Properties of steel like ductility,tensile strength, hardness depends on the composition of C and other alloy elements. Density varies from 7750 to 8050kg/m3 . Classification of Steel : 1. Carbon steel 2. Tool steel 3. Alloy steel 4. Stainless steel

Blast Furnace – Basic Oxygen Furnace (BF-BOF): This is the dominant steel production route in the iron and steel industry, involving the reduction of iron ore to pig iron in the blast furnace. BF-BOF operation relies almost entirely on coal products, emitting ~70% of CO2 in the integrated plant (BF iron making).
· Pig Iron and Its Manufacturing. Pig iron is the crude form of iron and is used as a raw material for the production of various other ferrous metals, such as cast iron, wrought iron and steel. The pig iron is obtained by smelting iron ores in a blast furnace. The haematite is widely used for the production of pig iron.
Pig Iron: -product of the blast furnace and the basis of all ferrous metals, used for the manufacture of cast iron, carbon steel and alloy steels. never used
15. 4/27/2015 15 Iron ore Common iron ores include: Hematite - Fe2O3 - 70 % iron ( a common iron ore) Magnetite - Fe3O4 - 72 % iron Limonite - Fe2O3 + H2O - 50 % to 66 % iron Siderite - FeCO3 - 48 percent iron To create a ton of pig iron, you start with 2 tons of ore, 1 ton of coke and half-ton of limestone. The fire consumes 5 tons of air. The temperature reaches almost 1600 0 …
enhance the production capacity of Ductile Iron pipes, pig iron & LAM Coke and power generation. In addition to the expansion, the company proposed to produce Ductile Iron fittings also. Lanco Industries Ltd. is manufacturing a total of 4 products namely Pig iron, Slag cement, D.I. Spun pipes and LAM Coke.
The key ferrous metals are pig iron, cast iron, wrought iron and steel. Pig iron is very hard and brittle while cast iron is also hard but brittle. Wrought iron is ductile, malleable and tough. Steel is an alloy of iron with 0.2-2.1% carbon and includes types like mild steel, high speed steel and stainless steel.
1. Iron and Steel Manufacture Technology related to the production of iron and its alloys, particularly those containing a small percentage of carbon. The differences between the various types of iron and steel are sometimes confusing because of the nomenclature used. Steel in general is an alloy of iron and carbon, often with an admixture of other elements.
