: So tell us more!  I didn't know this - and they must be different from steelmaking furnaces due to non-conductive charge material.  Please add any references you can. --Wtshymanski 16:43, 21 January 2007 (UTC)

message: We need a schematic cross-section through an arc furnace; we had one -but apparently it wasn't free enough for the Wikipedia. --Wtshymanski 02:45, 1 October 2007 (UTC)

thread_title: Need a picture

message: "Electric furnace" redirects here.  What is the difference between this and an electric furnace in a home (as opposed to propane, natural gas, etc.)?  Since this redirects here, there needs to be something about it, or a note indicating to go elsewhere.  I actually came here looking for information about electric furnaces because I don't know much about them and I am considering changing to one in my home due to the increasing propane prices.

replies: text: Electric furnace for space heating ought not to redirect here!  I've fixed this. --Wtshymanski (talk) 17:36, 9 January 2008 (UTC)
thread_title: Home electric furnace

message: Research use for arc furnaces is mentioned briefly in the introduction.  Is there an existing article for these that I can't find, or should I write a section for them in this article?  JaredAllred (talk) 16:55, 30 September 2008 (UTC)
replies: text: I'd be thrilled to read about such things - try searching for "arc furnace" and see if any laboratory articles turn up - if not, write away! (After a quick look I find nothing.)  I hope you've got a reference to cite, too - or maybe  a pointer to a good Web page. --Wtshymanski (talk) 19:41, 30 September 2008 (UTC)
replies: text: If I'm not mistaken, laboratory scale arc furnaces are usually deemed to have such ridiculously high heat losses, that any information about power consumption that one would derive from them would be worthless.  Rather, in the laboratory, induction or resistance type furnaces are generally used to simulate an EAF heat.  That said, pilot scale EAF furnaces do exist.  Again, heat losses are an issue, but better correlations can be drawn from pilot scale units, particularly if a database exists for scale up to a commercial size unit in a particular application.  The pilot units I know of are at Mintek (South Africa) and MEFOS (Sweden).  I'm sure there are more out there, and plenty of articles published...BSMet94 (talk) 20:13, 11 February 2009 (UTC)
thread_title: Laboratory Arc Furnaces

message: I took out the allegation about erratic quality of strip produced from EAF steel, there were no sources and it is at variance with my own epxerience.  No-one would be building EAF strip plants if there was no demand for the steel - and modern techniques of, say, auto body panel manufacture demand much higher steel quality than that of a generation ago. After all, EAF steel starts out as steel...blast furnace steel starts out as...dirt? --Wtshymanski (talk) 17:42, 21 January 2009 (UTC)
replies: text: But is this inherent in the EAF process or just the issue of control of raw materials you'd have in any process? --Wtshymanski (talk) 03:06, 9 February 2009 (UTC)
thread_title: Strip quality from EAF

message: I see several uses of the term "Lancing" in the main text, and I don't see either an explanation or a link to an explanation of this process.  Could someone please elaborate?  —Preceding unsigned comment added by 203.158.63.90 (talk) 11:46, 11 January 2010 (UTC)

thread_title: Lancing

message: In the last paragraph of the Construction subheading, there is this non-sensical sentence. I am not sure what the author was trying to convey, but I think it should be changed. 
"Therefore, the 300-tonne, 300 MVA EAF mentioned above will require approximately 132 MWh of energy to melt the steel, and a "power-on time" (the time that steel is being melted with an arc) of approximately 37 minutes, allowing for the power factor.

message: Just came here to find some background about a current news item concerning self-sufficiency in UK steel recycling. Came away very well informed — thanks to all.--217.155.32.221 (talk) 10:37, 23 March 2016 (UTC)
