Valmet has introduced its renewed Valmet IQ Quality Management System to optimize the entire value chain from fiber to finished product. The renewed version further extends traditional QCS by closing control loops for parameters which were formerly operated manually – such as retention and refining online optimization with wet end analyzers. The quality data, combined with Valmet’s industrial internet (VII) applications, makes possible Online quality modeling, for example paper strength, which can be now used in closed-loop control utilizing blending, refining and many other stock preparation parameters.
