Nippon Steel & Sumitomo Metal uses Rocky DEM to optimize material charging into a blast furnace

Steel producer, NSSMC, uses Rocky DEM to optimize material charging process

Nippon Steel & Sumitomo Metal Corporation (NSSMC) wanted to understand and improve the difficult-to-observe process of material charging into a blast furnace, which converts iron ore and coke materials into pig iron. To accomplish this, they needed a way to cost-effectively reproduce the material shape, size distributions, and flow behavior of the process, and do so quickly enough to act upon the results.

NSSMC used Rocky DEM to:

  • Accurately replicate the material size, shape, and flow behavior of their irregularly shaped coke and iron ore particles
  • Solve multiple simulations quickly by processing simulations on multiple GPU cards
  • Save time by making use of the Rocky Scheduler tool to run several cases in series

Discover how NSSMC:

  • Evaluated the behavior of non-sphere-based, realistically shaped particles in a quantitative way
  • Gained more insight into the angular particles’ flow and packing behavior
  • Saved experiment costs while ensuring more accurate results
