SINTER OPTIMIZATIONPROCESS OPTIMIZATION SYSTEM FOR
SINTER PLANTSFUNCTIONPRODUCT STRUCTURE

Sinter Optimization provides a complete history of processparameters including recipe, chemical and physical raw
material properties, and process measurements for acomprehensive analysis of both positive and negative
conditions of the sinter process.

• Process information system

The overall function of the sinter expert system is to enable
an optimized sinter machine operation with minimum
operator interaction. This solution counteracts processfluctuations caused, for example, by changes in the raw
material composition and quality, human factors andprocess conditions.
The sooner the system responds to abnormal or changing
process conditions, the smoother overall sintering
operation will be.

• Integration engineering

The accurate timing of control activities and anticipationof disturbances are of utmost importance to avoid criticalprocess conditions and to maintain a high production rate
at low production costs.

• Integration of online measurement device for chemicalcomposition of raw mix• Process models• Expert system
SERVICES• Erection supervision• Commissioning supervision• Metallurgical and process know-how• Operation fine tuning• Training on site for operation and maintenance• Remote support

The system guarantees shift-independent plant handling.
The result is smooth sintering operation around the clock,an increased equipment lifetime and reduced production
costs.

MAIN BENEFITS• Sinter Optimization is the most advanced
process optimization system available forsinter plants, enabling major cost savings andprocess 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
allows the production of sinter material of
the highest quality, while at the same timeeffectively reducing coke consumption.
• The optimal position and control of the burnthrough point, together with the homogeneous
flame front, result in maximum productivity.
