W pracy przedstawiono analizę efektywności wdrożenia nowej technologii, procesu walcowania normalizującego w przedsiębiorstwie hutniczym. Analiza została przeprowadzona przy użyciu archiwalnych danych finansowych z przedsiębiorstwa z lat 2000^2004. Ponadto autorzy opisali podstawy procesu walcowania regulowanego oraz prace badawczo rozwojowe niezbędne do wdrożenia nowej innowacyjnej technologii w przedsiębiorstwie hutniczym.

In the work the analysis of the efficiency of the application of the new technology of normalized rolling process in a steel plant was shown. The analysis was carried out using the archival financial data from the factory from 2000+2004 years. Additionally authors described the fundamentals of the control rolling process and research and development activities needed for application of the new innovation technology in a steel plant. Controlled rolling is a variant of the plastic working of metals and alloys, which is characterized by controllable stock heating conditions, temperature and deformation parameters strictly defined for a given chemical composition and preset product cooling conditions at different plastic working stages. As a result, the preset structure is obtained, along with a special type of substructures and hardening phases that assure a simultaneous enhancement of strength and impact resistance or provide special properties for the material.
