  1. Thanks iron dragon. In US, as I know, green steel is IN now a days. Open pit/ cupola furnaces are nearly closed in US and Europe, I can suggest you to electro refine iron with nearly 97+ percent pure iron It may be required some electro plating setup with some good chemical combinations. I can provide it to you but I think it's cost will be extra high for low supply+some extra documentation you will required. Any questions you have, you can ask, I will share whatever I know, I am a person who prefer to share things , without hiding things.
  2. Thanks a lot, i think I share something very directly , so many can not understand. The new green steel technology is to melt the iron ore directly without carbon addition to remove oxygen from ore. (Reduction) Ahhh steel , it's a long story to make it, some time to do two anti steps to make it, lets discuss Reduction is done with carbon to eat oxygen from iron ore, so iron is reduced from ores , but resultant iron is always pig or cast iron with 4 to 8% carbon. Then this iron is melted and oxygen is blown to reduce carbon as carbon Di oxide and carbon mono oxide plus some slag. When C is less then again iron is melted and alloyed metals are added. If it's wrought iron, then wrought iron is melted and carbon is added to get proper carbon content and alloyed metals are added. Alloyed metals have a different gravity , so they not properly mix in iron, e.g iron is stable and melted at 1300c while cr is volatile at this tamp, so Argon gas is blown to make a proper mix of alloys. Now what I discuss in last massage was, to stop emissions of carbons oxides, we have to controle the system from start, Iron extraction from ore, c is added to replace oxygen, and then this carbon become a mother problem for steel, nitrogen/hydrogen also work well to reduce iron , purpose is to replace oxygen with any reducing agent. Little hurry, I share what I know. Oh and melting alloys, it's not a problem but you need time to change chemistry, only 3 percent copper can be dissolved by iron in one melt. So what about Damascus with copper sheets added. Induction is power, electricity is charm , I want produce low carbon iron, so I can make some steel alloys as required. In ss 202 to 316, carbon is the actual thing. Some people are producing SMS from pig, on small scale, but they not use gases like oxygen to remove carbon, they use some chemicals. I am looking for that combination,
  3. Thanks frosty, I know here on forum, people are more knowledgeable than me. You also have a good knowledge on steel as your first reply was very accurate. I was looking to work directly on ore in blast furnace(old methods are still active here) and reduce iron with hydrogen instead of carbon to directly produce low carbon iron but .....! Hydrogen is another trouble in handling and safety, blast furnace guys thinking that I am making something rare Knowledge is nothing without proper places to apply! Well I will wait for more guys to chime in. I have very low knowledge in forging, I have seen some guys here making Damascus steel and export it. It's also a nice project and my next task
  4. Thanks frosty, you are right that Bop or BOF process are used in large scale furnaces. I am from Pakistan, steel production is reduced as govt decide to close all larger steel producing furnaces. So a small scale can be a good option. We cast the iron, so we are aware of boiling iron very well and we know how to give respect to have respect for molten metal. Acids are way long and expensive option for production. Though its most clean method. Electric refined iron production is also an option to get nearly pure iron but it also way lengthy and very controlled system requiring setup. """ Oh one more thing"" we use the word "steel" only for low carbon iron, with content less than 1 percent. Any iron more than 1 percent in carbon is called iron in general. In case we add low grade non-magnetic steel scrap and melt it, then we add alloyed metals to make it 316 grade, we still need argon to mix the metals properly as cr has low boiling point and will not mix with iron properly, In general I want avoid mixing of gasses in molten metals.
  5. Yes it is, blowing oxygen in molten iron, is not an option, in both ways, availability of apparatus and safety issues, Thats why I am looking for chemical compositions for carbon reduction, if possible for someone to share.
  6. It's about opportunities, that's why I want make it, instead of buying it, I am assure, most of time, blacksmith have more experience, blowing oxygen in molten iron to release di and mono oxides of carbons are ok, but it needs some special equipment like lance , oxygen supply, high pressure , a built in system, etc....
  7. I want make 316 grade steel with pig iron, I know about Oxygen furnaces, But I have only a 70 kg induction, blowing oxygen need special equipment, I want know any special fluxes or chemicals that can be used for lowering carbon content and proper mixing of alloyed metals
