Valmet IQ Controls and Applications
State-of-the-art software for ultimate quality control
The most important task of the controls and optimizations is to provide the capability to produce stable quality efficiently at economical optimum. Valmet IQ Applications are the core of the system with clear user interface and intelligent control applications which allow you to manage the machine line performance. Efficient user experience gives a clear view of process performance and product quality, at all times.
Papermaking processes are continually changing. Conditions vary in both intentional and unintentional ways, leading to performance gaps over time. Valmet bridges the gaps with the latest diagnostic tools, helping you predict and avert problems while improving your process performance and quality.
Using multivariable predictive controls (MPC), Valmet IQ Controls and Applications effectively manage interrelated paper qualities. Valmet’s solution keeps processes balanced, taking predictive actions across control loops. Our unique multivariable process models are based on decades of first-hand knowledge and real-world data, making quality truly predictable.
The Valmet IQ MD Optimizer integrates fast responding wet end process controls and dry end feedback controls to achieve a higher level of paper quality control performance. Paper process variability is reduced before the wet sheet is formed. You can perform faster startups and grade changes, reduce dryer breaks and get better runnability with stable short circulation improving uniformity of the wet sheet.
The control can be configured step-by-step from simple basis weight, feedforward weight and moisture control applications to more complex ash and retention control applications. Full scope Valmet IQ MD Optimizer can simultaneously manage the thick stock flow, filler flows, retention chemical flows and steam pressures to achieve smoother MD properties during steady-state, speed changes, and process upsets.
