Get PriceThis kind of iron is called Cast Iron and has a slightly lower carbon content 2 – 3 %. This is even harder than pig iron. Wrought Iron/ Malleable Iron. Wrought Iron is the purest form of iron available commercially available and is prepared from cast iron by heating cast iron in a furnace lined with Haematite (Fe2O3).
Get PriceThe process begins by preparing the puddling furnace. This involves bringing the furnace to a low temperature and then fettling it. Fettling is the process of painting the grate and walls around it with iron oxides, typically hematite; this acts as a protective coating keeping the melted metal from burning through the furnace. Sometimes finely pounded cinder was used instead of hematite.

Get PriceAnodising (also spelled anodizing in American English) is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts. The process is called anodising because the part to be treated forms the anode electrode of an electrolytic cell.
Get PriceSep 20, 2019· In the case of steel, this requires that the iron be liquid, and the other atoms allowed to mix with it. We normally do this by smelting iron ore (primarily Fe2O3) with coke in a blast furnace. This produces liquid iron with a carbon content of about 4% (the saturation level of carbon in iron).
