Made in the U.S.A. for more than 100 years
Last week, a lot of the work focused around the vacuum tank degasser, or VTD. Read on to learn more about this important process in steelmaking:
Situated just behind the melt shop, the crew has been erecting the structure of the degasser building. As the name suggests, a VTD removes various gasses trapped in molten steel by creating a vacuum to draw them out. This is critical to ensure that no bubbles or impurities arise during casting or the additional refining process.

In the photo below, you can see the crane lowering a VTD bag filter into the degassing facility. Gas removed from molten steel will be processed through these filtering chambers.
