CGun Posted June 3, 2020 Share Posted June 3, 2020 Has anyone tried blowing pure oxygen into a steel melt to remove the excess carbon? I am curious if this works on a small scale. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted June 3, 2020 Share Posted June 3, 2020 Kelly predated Bessemer's experiments using refractory lined barrels; of course he was blowing air into molten cast iron to make steel. Blowing pure O2 into molten steel should work but may be quite exciting as the temp will rise as a side effect. Wouldn't it be extremely much simpler/cheaper to just start with low carbon steel to melt? Perhaps 1018 would work? They make some ultra low carbon alloys for extreme malleability work as well.

CGun Posted June 3, 2020 Author Share Posted June 3, 2020 Oh it definitely would. I am just looking for ways to control the steel so I could use steel scrap. Oxygen blowing might allow me to salvage messed up melts as well where the steel absorbed carbon from its evironment Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted June 3, 2020 Share Posted June 3, 2020 Still may be cheaper to buy known good steel! Quote Link to comment Share on other sites More sharing options...
CGun Posted June 4, 2020 Author Share Posted June 4, 2020 You are probably right. I should probably just buy steel alloy as shot and melt it from there Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted June 4, 2020 Share Posted June 4, 2020 That is probably the expensive way too. Much steel is remelt from scrap and then adjusted in the furnace to meet the spec needed. What would be nice would be steel scrap from a industrial process that used that alloy. Quote Link to comment Share on other sites More sharing options...
CGun Posted June 4, 2020 Author Share Posted June 4, 2020 You're probably right. I will see what my local scrapyard has. Thanks for all your help. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted June 4, 2020 Share Posted June 4, 2020 Go upstream from the scrapyard! Most scrapyards have unsorted scrap. Quote Link to comment Share on other sites More sharing options...
