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,
