In the ladle at the ladle station the steel slags over except for where a special "porous plug" bubbles argon from the bottom to homogenize the mixture and float impurities to the surface. Thsi makes an "eye" in the steel and that's what it's actually called. Overhead a larger stir lance that can inject larger amounts of oxygen to stir the ladle waits to be used if needed. So, it's over. The steel mill where I've worked for 22 years has closed the "melt shop" where now steel is made by melting scrap and refining it into new and better steel grades. No more. I went in early AM to catch the last heat melted and followed it down the line. Most photos taken with the Fujifilm X100S and some with a Fujifilm X-M1 and Fujinon 35mm f/1.4.
