PSI Solution Plans Smelting in ThyssenKrupp Nirosta Steel Mill

PSI has successfully replaced the previous version of PSImetals for the heat and caster sequence planning at ThyssenKrupp Nirosta that had been in operation for more than 10 years. The modernization is the result of a unification of the planning solutions in the stainless steel plants in Germany, the U.S., and China.
 
IT investments for the ThyssenKrupp Stainless production plant to be built in Alabama are to be assured by the PSI system proven at the German sites of Bochum and Krefeld. The systems have been operating since May.

The scheduling of the daily smelting process at the steel plants is supported by the PSImetals functions for advanced line sequencing. Based on the needs of the cold rolling plants, a continuous supply of the steel mill with smelting orders is achieved.
 
PSImetals functions such as rescheduling of a heat in case of analysis deviations, the re-feeding following interruption of a caster sequence, or the re-sorting of heats in a sequence or entire sequences in the program allow for quick reactions to short-term directives or disruptions in steel mill operations. If needed, a simulation mode also secures the current planning status with online changes.

With the modernization, PSI says that ThyssenKrupp Nirosta would also like to take advantage of standard functions such as multilingualism and configurability of planning rules. In the future, plant-specific adjustments can be operated flexibly by the key users.


ThyssenKrupp Nirosta
belongs to the division Stainless Global in ThyssenKrupp AG and is one of the world’s leading producers of rust-, acid-, and heat-resistant stainless steel products. ThyssenKrupp Stainless USA is an independent subsidiary within the Stainless Group and is currently constructing a new, integrated plant for non-corroding stainless steel flat products in Calvert, Ala. In August 2008, PSI was awarded with the delivery and implementation of PSImetals as the system for the optimization of the production processes in the steel mill and cold rolling mill.
 
PSI AG develops and integrates complete solutions, on the basis of its own software products, for the management of energy networks (electricity, gas, oil, heat, water), cross-company production management (metals, automotive, mechanical and plant engineering, logistics), and infrastructure management for telecommunications, transport, and safety.
