QUALITY COSTS AND VALUE ENGINEERING IN THE STAINLESS STEEL COLD ROLLING PROCESS

Abstract

Dans cette étude, les coûts de qualité sont considérés comme un indicateur du niveau de qualité et d'ingénierie de la valeur et la relation entre les coûts de qualité et l'ingénierie de la valeur est analysée dans le cas du processus de laminage à froid de l'acier inoxydable. Les limites chimiques standard des alliages métalliques sont analysées et l'effet des variables internes sur les coûts de production et de qualité est discuté. Des analyses similaires ont été effectuées pour les conditions limites du processus standard. Il a été démontré que le processus de laminage à froid, qui a la valeur la plus faible dans la chaîne de valeur de la production de produits en tôle d'acier inoxydable, n'est pas aussi bien pensé et que la valeur a été créée en modifiant de nombreuses propriétés du matériau en fonction du domaine d'utilisation. En utilisant des processus tels que la sélection des matières premières et l'optimisation du traitement thermique, deux nouveaux alliages (304E et 304U) ont pu être produits sans modifier la structure chimique, et les coûts de production ont pu être réduits grâce à des études d'amélioration de la qualité menées parallèlement à l'ingénierie de la valeur. Les coûts de prévention, un indicateur important, ont également été réduits. Dans l'étude, les causes des sources de coût de la qualité sont présentées séparément sur le processus et leurs relations entre elles sont analysées. Bien que les indicateurs aient été analysés sur le processus de laminage à froid de l'acier inoxydable, ils ont été jugés applicables et adaptables à toutes les productions continues de matériaux.

In this study, quality costs are considered as an indicator of quality and value engineering level and the relationship between quality costs and value engineering is analysed in the case of stainless steel cold rolling process. The standard chemical limits of metal alloys are analysed, and the effect of in-boundary variables on both production and quality costs are discussed. Similar analyses were carried out for standard process boundary conditions. It has been shown that the cold rolling process, which has the lowest value in the value stream of the production of stainless steel sheet products, is not as thought and value has been created by changing many properties of the material according to the usage area. By using processes such as raw material selection and heat treatment optimisation, two new alloys (304E and 304U) could be produced without changing the chemical structure, and production cost could be reduced with quality improvement studies parallel to value engineering. Prevention costs, an important indicator, have also been reduced. In the study, the causes of quality cost sources are shown separately on the process and their relations with each other are analysed. Although the indicators were analysed on the stainless steel cold rolling process, they were determined to be applicable and adaptable for all continuous material productions.
