Abstract

In order to ensure the correct assignment of the approx. 180 work rolls of the finishing line of the hot strip mill Bochum works of ThyssenKrupp Steel Europe AG, a new system based on RFID technology has been implemented. The correct selection and positioning of work rolls is imperative to achieve an optimum production. Characteristics as material, diameter, shape, surface and grinding type are key attributes which differentiate work rolls for a customized application. A work roll set configuration not matching a rolling schedule or the incorrect positioning in the mill stand can lead to severe disruptions or quality losses. The technical solution described in this paper has practically proved its efficiency and reliability. Easiness and simplicity of operation are considered as a decisive factor. Online virtualization for all net connected working places enables direct communication among the working team at the finishing rolling mill group of stands and at the roll turning shop. Easy requirements for technical maintenance in combination with other clear advantages guarantee practical and functional applicability for this system. Additionally, the mounted system and RFID infrastructure can be used for further improvement of work rolls logistics as well as for other functions, e.g. for bearings control.
