I read this and I felt like it was about me ! I'm in the process of building my own steel foundry for my iron ore magnitite. I'm heating it was foundry coke and I have to reach a temperature of 3400 degrees and at 3000 degrees it employees making a sonic boom then the temperature rises so fast with in one hour it's 4000 degrees you have to actually shut it down and I'm pouring gun grade hard steel .2000 pounds of the iron ore crushed I should get 1500 pounds of gun grade steel back. It's assume!
