RAMMING SPEED   Baffled About Baffles?   Christy Refractories had some great questions regarding the OXI-RAM degassing system vs. the competition.   These questions were the foundation for RAMMING SPEED!   You may look forward to seeing RAMMING SPEED on a regular basis and please be certain to forward any questions or helpful hints to me for future publication.   Now, about these baffles...   OXI-RAM Product Specs for Crucible Mount Units:   - Electric Drive   - Air Drive   Q. "If the competition is using baffles on either side of their degassing units, why don't we?"   A. The principle behind the baffles in the first place is to not generate a vortex when degassing. Some competitors use baffles to interfere with the vortex generation, while other competitors change direction of the spinning rotor. The OXI-RAM uses a protective sleeve around the shaft therefore interfering with the vortex as well as reducing oxides in the melt. Q. "What should I tell a customer who asks: Can the oxide build-up between the non-rotating protective sleeve and the rotating drive shaft fracture the non-rotating protective sleeve?"   A. One of the most successful features of the OXI-RAM systems is the inert gas conversion kit. This kit allows for Argon (Ar) or Nitrogen (N) drip into the protective chamber.     These inert gases displace the air in the chamber. Argon is preferred because the specific gravity is heavier. By displacing the air we are removing the oxygen from the chamber and reducing the possibility of oxide build-up. The Argon drip enhances the life of the shaft and sleeve. This is a distinct advantage over the competition! Q. "What type of seal is used between the rotating shaft and the mounting plate to keep a positive inert gas pressure inside the top of the non-rotating protective sleeve?"   A. Again, based upon the specific gravity of the inert gas used, (Argon 39.948; Nitrogen 14.006) vs. air a seal is not required.         - Kris Thut
