Abstract
The authors of this article have been supporting the collaboration between NMSTU and Danieli specialists for over 10 years in science and technology, and in international personnel training.
Constant push forward for more flexible and cost-effective production makes it obvious to search for better ways to control and improve product quality, personnel competence, and technological factors. The need to make fundamental changes in mill layouts while construction or reconstruction underlines the role of developing and using adaptive models that give alternative routes to solve problems that arise during production using systematic analysis.
Based on structural matrix approach we have developed a programme that automatically adjusts rolls gaps in the stands of the mill while considering the tonnage of rolled metal for each groove and dimensions of the rolled stock after finishing stand. This programme uses «priority coefficient» to maintain tolerances of the product when the cross-sections of the grooves are constantly changing because of wear.
Other vital features are «wear matrix» that calculates wear in different points of the groove and «the coefficient of non-uniform deformation» that shows the differences in reduction along the cross-section of the groove. Work effectiveness of metallurgical enterprise depends on personnel qualification level. Qualitative performance of personnel may be assessed by using quantity indexes. One of such indexes is the complex index of personnel competence.
ISO 9000 standards require the staff to be the main resource in the quality management system, as social factors in particular not technical ones provide better quality.
Thus, it’s necessary for the high management executives to take care about the reproduction of intellectual potential if they are oriented on long functioning.
Adaptive training programs for employees at startup facilities in Russia, as well as for the perspective engineers for Danieli have become one of the most successful NMSTU and Danieli projects together with International Union «METALLURGMASH» and «METALLURGMASH Engineering».
