Edgecontrol

Title:Minimised yield losses by innovative integrated edge-drop, width and shape control based on soft-sensor technology and new actuators in cold rolling mills.
Abstract:The project Edge control aims at systematically studying width variation and edge-drop in cold rolling mills. Mechanisms producing these phenomena were investigated and classified for different materials and mill types. Advanced strategies for controlling edge-drop and width were proposed. An integrated model predictive control approach is proposed to simultaneously deal with flatness and edge-drop in combination with appropriately optimised mill scheduling and setup. Since edge-drop sensors can only be placed some meters away from the roll gap, a dominant time delay will appear, so that classical feedback control is not recommended. Instead, a controller with time delay compensation, e.g. Smith predictor or internal model control (IMC), is suggested.

INFOMAP

Title:Integration of complex measurement information of thick products to optimise the through process geometry of hot rolled material for direct application
Abstract:Measurement systems covering flatness and dimensional accuracy on plate/strip products are widely available. Output is usually in the form of contour plots or ‘maps’, providing visual feedback to mill operators who must interpret the information subjectively, and to technical staff for investigative purposes. Objective interpretation of these maps is not straightforward, and comparison of output from devices of different type or manufacturer often presents further difficulties. This project seeks to address this, developing a tool for objective interpretation of maps from different devices along the process route, generating concise data suitable for use within automatic control/advisory systems.

Title:Industrial demonstration of novel adaptive flat bearing with adjustable thickness for flexible gap control in rolling mills
Abstract:Increasing demands for better product quality, thinner strips and greater flexibility of the production lines confront rolling mills with new challenges. The e-mobility sector requires thinner sheets with even tighter thickness tolerances to increase efficiency of electric motors. Therefore, it is necessary to reduce vibration level at the rolling stands. For this purpose, the adaptive flat bearing for rolling mills was developed, which enables passive and active vibration damping. This project will be the first industrial test of the adaptive flat bearing. Installation will be performed on a cold rolling mill of thyssenkrupp Electrical Steel.

NEWTECH4STEEEL

Title:Enhanced process stability and product quality in steel production by exploitation of breakthrough technologies for real-time monitoring, control and forecasting inspired by big data concepts
Abstract:The constantly growing requirements to European steel production concerning product quality and process efficiency are accompanied by massive increases of data and information collection at the processes and about the products. The final aims of this proposed project are the developed and applied methods for an improved process observation and control as well as extended tools to assess and forecast (intermediate) product quality as examples for the successful application of new technologies, to provide evidence of the applicability and efficiency of such methods.

RADIFLAT

Title:Radar-based flatness measurement and control in strip rolling and processing lines
Abstract:The worldwide first radar-based strip flatness measurement system, including strip edge detection and width measurement is developed for strip processing lines (rolling, levelling, quenching, ...). The basic technology consists of a multi-radar measurement system that is created to operate with high frequency/resolution (240–300GHz) and precisely work under the extreme conditions of strip processing in terms of dust, vapour, high temperatures, etc. Sophisticated signal processing and process modelling methods will be developed to integrate the measurement technology in the process control and automation.
