Talk:Extraction of iron

I have amended this page and have removed the designation stub, because I do not think it is one. There are various articles on processes, and it will be better for the user to go to these rather than to expand this article. It may be that some other 'see also' cross-references are needed.

Brittleness

 * It is far less brittle than iron.

Pure iron isn't particularly brittle, perhaps there is confusion with the brittle alloy cast iron. Pretzelpaws 22:51, 7 November 2006 (UTC)

In general, the higher the carbon content the more brittle the iron. (The same goes for most other alloing material) Seniorsag 23:17, 25 December 2006 (UTC)


 * If it contains 4-5% carbon, it is pig iron or cast iron, depending on wherther it is a finished product or not. If it contains a significant (but smaller amount) of carbon, it is not iron, but steel.  Finished wrought iron and bar iron (the unmanufactured product) are durable, but go blunt.  Wrought iron will be coldshort (brittle when cold) if it contains phosperus as an impurity, or redshort (brittle when hot) if it contains sulphur.  Redshort iron cannot be forged and tis thus useless.  Peterkingiron 17:19, 13 January 2007 (UTC)

Merge proposal
\ I think what you have done is absolutely stupid! You know there are some people here who want to study with solid information and this is not a good example!

We still have too many articles dealing with the same subject. There are long descriptions of the process under iron and blast furnace. Steel may also cover some of the same ground. It may be appropriate to retain this page as a general to provide a brief summary of the processes. The iron article (which is a gerneral one on the chemical elemtn) might be cross-referred here, though the use of the 'main' template, but if so, this one should be cross-referring to blast furnace and to other processes.

A few problems
I just noticed this article. We've apparently completely forgotten to mention DRI processes. There are a lot of Midrex furnaces out there making iron pellets, never mind the fluid bed DRI processes. Also, where does the 2000 degrees C come from? I'm pretty sure that no blast furnace operates that high.
