Rexroth Solution:

  • MOSIHS (Modular SImulation of Hydraulic System) program
  • Hydraulics engineering & commissioning
  • Rexroth control software for closed loop control
  • Rexroth hydraulics technology:

Results:

  • Advanced MOHSIS simulation enables cutting-edge design and testing of new hydraulic circuit
  • Replaced mechanical tilt drives and gear reducers with hydraulic cylinders that lift and lower distributor chute
  • Simulation crucial tool for achieving chute endpoint accuracy of.0.01 inch (0.25 mm) -- one-tenth of one degree
  • Reduced number and complexity of motion control elements, for easier and more efficient blast furnace operation
  • More precise control of raw material distribution within blast furnace, improving process control
