Intelligent automation for sinter plants

The sinter control system in combination with the sinter optimization system creates the next level in intelligent sinter automation. The optimal interaction between sophisticated models and the expert system provides extended assistance to plant operators and minimizes the risk of human errors.

 

Our solutions

Our reliable and most advanced process control system combined with our process optimization system provides major cost savings and process improvements without compromising raw material selection, sinter quality, energy efficiency, and productivity.

The optimized raw mix calculation with precise chemical targets and additional control loops is the basis for producing sinter of the highest quality, while at the same time effectively reducing coke consumption. The optimal position and control of the burn-through point, together with the homogeneous flame front, and optimal raw-mix moisture result in maximum productivity.

The system guarantees shift-independent plant operation where manual interactions are reduced to a minimum. The result is smooth sinter plant operation 24/7, increased equipment lifetime, and reduced production costs.

 

Advantages

  • High productivity – Sinter plant is running at peak performance while minimizing consumption of fuel and electrical energy for waste gas fans
  • Product quality - Chemical and physical properties of the sinter product maintained at the desired levels
  • Reduced fuel consumption - Precise mixing of charged materials results in homogeneous quantity of return fines
  • Stable and shift-independent operation - Best-practice sinter plant operation 24 hours a day to ensure efficient production
  • Fast response to market demands - Quick and flexible reactions to market requirements as well as unexpected situations
  • Return on investment - The standard period is expected to be less than one year
