Project description

thyssenkrupp rothe erde Germany GmbH, the end customer of INP Germany, operates a ring rolling mill for the production of rings made out of steel, aluminum, copper or stainless steels. The rings are manufactured in the requested sizes and materials in the radial-axial roller bearings (RAWs). In the next production step, the steel rings produced in the rolling mill are subjected to heating and cooling treatment in the tempering plant consisting of annealing furnaces and cooling water tanks to increase durability and quality and to achieve the desired hardness.

Scope of work

INP Deutschland GmbH was commissioned to migrate various inventory visualization systems including the associated production databases to a new plant-wide uniform visualization system, to establish the connection to the plant-wide SAP system for data exchange for the higher-level production management, as well as to achieve an increase in the level of automation and digitalization through the development and integration of a digital furnace book incl. batch and order management, a (partially) automated parts tracking system, and through standardized furnace controls via uniform programmers.

The existing visualization systems (obsolete WinCC stations, Protool panels, Intouch visualizations, etc.) of RAW lines 1–3, 4 and 5 as well as the heat treatment system were migrated to a uniform WinCC system V7.3.

Particularly noteworthy was the requirement for a plant-wide standardized operating, authorization, and visualization concept for the operator, taking into account an ergonomic design for the plant drivers (not a pure migration solution). The existing MSSQL databases had to be migrated and adapted to the latest versions in order to transfer all necessary data for connection of the WinCC tags to the plant production control system (SAP).

Together with the plant, a model for (partially) automated parts tracking within the production line was developed and implemented with VBA via WinCC. Similarly, uniform programmers were integrated to control the numerous furnaces.
