steelman Posted August 31, 2018 Share Posted August 31, 2018 That video is fascinating! Thank you for posting it. The New modern mini mills are electrically charged, use mostly shredded scrap, and heat the steel much hotter, to near white in color. The steel flows like water at those temperatures, and many of these mills are casting continuously, rather than in smaller batches or heats, to a near net shape. The chemistry and physical properties are so ACCURATELY controlled (where the fellows were adding manganese and other minerals) that the actual strength of most steel now is much higher than that of only 20 years ago. I find watching these videos very interesting, and seeing all of the work that goes into making steel, it is a wonder it doesn't cost more. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/54165-steel-mans-servant/#findComment-405267 Share on other sites More sharing options...
