Continuous regeneration of industrial pickling solutions and recovery valuable materials are implemented in a pilot-scale plant including diffusion dialysis (DD), where HCl is recovered, membrane distillation (MD), concentrated, reactive precipitation (CSTR), metal ions recovered different forms. The integration the three processes allows to minimize waste streams generation accomplish closed-l...

The improvement of the performances of a complex production process such as the Sollac hot dip galvanizing line of Florange (France) needs to integrate various approaches, including quality monitoring, diagnosis, control, optimization methods, etc. These techniques can be grouped under the term of intelligent control and aim to enhance the operating of the process as well as the quality of deli...

Causes for deposition of defective galvanized coating (lumpy deposition of coating during hot dip galvanizing) of carbon-steel wire have been investigated. It is established that the lumpy deposition is caused due to segregation of silicon on the surface of steel wire. Due to this change in composition of the steel at surface, the regions get modified and lie in Sandelin hyper reactive zone. Th...

Axially moving strips are frequently encountered in industry for various applications. On the one hand, accurate models of transverse displacements of strips are desired for plant design and safety or reliability reasons. On the other hand, the models may serve as a basis for model-based controller and observer design. For the latter also, the complexity of the models should be as low as possib...

Incremental Support vector machine (ISVM) is a new learning method developed in recent years based on the foundations of statistical learning theory. It is suitable for the problem of sequentially arriving field data and has been widely used for product quality prediction and production process optimization. However, the traditional ISVM learning does not consider the quality of the incremental...

Micromagnetic NDT techniques like the measurement of the magnetic Barkhausen noise, the incremental permeability and the harmonic analysis of the tangential magnetic field allow deriving inspection procedures to online monitoring and control machinery parts and components in production processes in order to characterize mechanical properties like hardness, hardening depth, yield and tensile str...

The work is devoted to the problem of flexible small-scale production galvanized steel various sizes on a continuous hot-dip galvanizing unit with varying productivity. main focus heat treatment strip, requirements for which limit In conditions disturbances, it necessary proactively control using models, or reduce speed strip ensure that are met. Unlike most works control, this focuses cooling....
