Purpose: This paper deals with rolling mill process control and optimizations using mathematical model. Design/methodology/approach: The rolling process is very complex with high demand for energy, material and equipment. Furthermore, rolling mill requires precise setup to be able to roll specific material. Therefore, rolling mill model system is required in most production, research and development...
Purpose: Study aims to investigate the elastic properties of porous Si3N4 thus three different starch type as pore former additives were used to obtain different pore characteristics. Design/methodology/approach: Porous Si3N4 ceramics were fabricated by partial sintering and pore former addition. Pore formers consisted of elliptic, round and angular particles were used. Elastic, shear and bulk moduli...
Purpose: The main goal of present study is try to find the influence of severe plastic deformation using the ECAP (equal channel angular pressing) process and different processing routes on structure formation, properties and lattice strain of EN AC 51100 alloy. Design/methodology/approach: The cold ECAP behaviour was determined using three different processing routes A, Bc and C and four repetitive...
Purpose: Theory of construction similarity has its roots in the theory of physical similarity. The model in the theory of construction similarity is a model construction. Model in the theory of similarity of construction and technology is construction and technology standard. Design/methodology/approach: The fundamental aim of the work is the selection of design features in particular type sizes of...
Purpose of this paper: The presentation of the results of empirical research in the leading automotive companies in Poland. The study concerned the quality management system in those organizations. In this study, there were presented chosen research results in terms of used tools, methods and thinking for quality management system (QMS) in those companies. Design/methodology/approach: The studies...
