How does blowing O2 into the molten iron increase its temperature? Is this caused by the burning of impurities?--Eraticus02:48, 27 December 2005 (UTC)[reply]
BOF - Basic Oxygen Furnace, many large U.S. steelmakers refer to the process thus, but I am uncertain of where BOS is used and am thus reluctant to edit it. --shadow23:10, 21 July 2006 (UTC)[reply]
I agree. A BOF is an American term for a similar process. However, the steps taken are slightly different and different amounts of different alloys are used. Ask any old timer steelworker and he'll chew your ear off about it. BOF has to be a separate article simply because it refers to American steel making. Merging the two would not be correct. -User Lackawanna
I thought the LD process replaced the Bessemer and the Bessemer replaced open hearth. That's what the other articles say. --72.128.33.11512:49, 25 September 2006 (UTC)[reply]
Even after the introduction of BOF's, open hearths and BOF's were in operation at many steel plants at the same time even though a BOF was a better process. A couple reasons why include the potential loss in output capacity if an open hearth was shut down and the multi-million cost of building another BOF.
BOF's have existed for many decades.
Bessemer andThomas-Gilchrist converters were invented before the Siemens-Martin process which largely but not fully replaced them. The article repeatedly describes the basic oxygen steelmaking as a refined version of the Bessemer process, but since it is basic it may be better to describe it as refined version of the Thomas-Gilchrist process, albeit refering to the Bessemer process is correct in the sense that the Thomas-Gilchrist process was a developed from the Bessemer process.150.227.15.253 (talk)09:42, 22 May 2024 (UTC)[reply]
I've just noticed that there are two separate pages on the basic oxygen furnace and process, that largely repeat the same information. I'm recommending that they be merged.Sentinel7511:48, 30 July 2007 (UTC)[reply]
Again, they should not be merged as they refer to two kinda similar but different processes. A BOF is an American term for the American process. BOS is the foreign equivalent. Merging the two would be like merging an article about a foreign car with an American car just because they are both about cars. -user Lackawanna—Precedingunsigned comment added byLackawanna (talk •contribs)21:48, 20 September 2008 (UTC)[reply]
It appears that much of this page has either been copied by or copied from the Bluescope steel webpage of the same topic (http://www.bluescopesteel.com/index.cfm?objectid=5248A606-DDF6-4E80-B74FA4A95B3F5107) Someone has committed plagiarism, something should be done—Precedingunsigned comment added byEagle 1.10 (talk •contribs)10:59, 13 September 2007 (UTC)[reply]
I'm very interested in smelting and forging. Can anyone tell me where and how to learn the basics of the craft? Example, I would like to construct a basic crude furnace in my back yard and I wanna learn how to melt iron and oxidize it into steel and then hammer it and work it into swords and shields or stuff. I'm good in chemistry and I'm in highschool so I understand the processes, I am not a noob. Please assist me.--Ren Storm21:19, 28 September 2007 (UTC)[reply]

THis needs to be linked to the BOS disabiguos page. I'm new and don't know how to work a disabiuguos page (or spell one)Basic Oxygen Steel (BOS) making.It's refered to as such in Western australia (we produce 10% of the worlds iron, Yay!)Oxinabox03:53, 2 October 2007 (UTC)[reply]
We just spent a long time reducing our Fe2O3 to Fe, and protecting it with slag for the hot blast air to preven oxidisation, And now we're removing impurities By "Directing a jet of Pure Oxygen at the molten Pig Iron", how come the iron isn't oxidised?Oxinabox03:57, 2 October 2007 (UTC)[reply]
How about some diagrams and a few pictures!—Precedingunsigned comment added byMaelli (talk •contribs)08:31, 27 June 2010 (UTC)[reply]
I agree that oxides of calcium and magnesium are basic in nature, but can they be said to have apH? In the solid state they surely contain no hydrogen ions at all.Moletrouser (talk)15:59, 16 April 2012 (UTC)[reply]
When I studied metallurgy in the late 1970s, LD was Linzer Düsenverfahren (Linz Jet method)— Precedingunsigned comment added by195.43.48.142 (talk)11:04, 20 October 2015 (UTC)[reply]

"The BOS vessel can be tilted up to 360°." That is not what "tilt" means. That would be "rotate." What was the text supposed to say there?IAmNitpicking (talk)19:41, 28 March 2019 (UTC)[reply]
British oxygen approached H Bingham & sons Ltd to commence trials using direct injection of oxygen. A one tonne Bessemer converter was installed and charged with molten Iron from a cupola. Initial trials were conducted using steel tube to inject oxygen but this process was fraught with problems. Eric Bingham designed a water cooled copper lance of which I have personally lowered and hoisted with a hand winch. The water cooled lance proved very successful and reliable resulting in H Bingham foundry steel making up untill the early eighties. My late father James Narey was involved in the trials as foundry manager. I joined the Foundry in 1970 and controlled the converter for several years with a simple hand valve watching the flame change as it burnt off elements and not allowing the reaction to get out of control of which can easily have explosive results as oxygen builds up in the slag. I know that in the years they had visitors from South Africa and probably other countries. So much history gets lost or distorted. I would like to publish this as a matter of fact.85.31.131.100 (talk)01:02, 25 October 2024 (UTC)[reply]
