In continuous casting steel production a significant loss reduction – in terms of scrap material, time and money – can be achieved by developing an appropriate algorithm for the prevention of molten steel sticking onto mould. The logic of such algorithm should be simple and manageable to ensure its practical implementation on a computer system via the usage of thermo sensors. This suggests that both the algorithm and the automated data collection can be implemented by means of applicative software. Despite its simplicity, the algorithm should accurately trace physical phenomena in molten steel.

The production of castings can be considered as production in transport. Is necessary to plan and supply the huge quantity of different materials. The expenses of these materials reach 80 % of all expenses which give the importance to planning of working materials for serial production. To perform all mentioned in planning phase of production is necessary to define satisfactory method of determination of kind and quantity of working materials and carriers of necessary information for planning. As entrance have information from Operational sheet, List of operations and List of tools.

It is investigated the possibility to be accounted the raw material’s quantity for each casting on the basis of design draft and mass of casting. To precisely determine the quantity of raw materials is necessary to technological procedure is preliminary accomplished. This task can be reached if correlations between kind of castings, shape complexity of castings, relations between total and net mass of castings, relations between mass of cores and mass of net casting will be established, with all respect toward applied technology and production methods of cores, the molding box and models.

The purpose of presented research was to develop feasible model for leadership competence management in metallurgical companies. Results of the research are presented in the form of a structured procedure for leadership competence development and performance review. Analysis of entry requirements for employment in metallurgical companies synthesized presented set of leadership competences and matrix for calculation of leadership success was developed. With usage of these two tools it is possible to quantify the leadership performance which represents great advantage in leadership benchmarking process. During the research additional set of problems was defined. These problems were addressed heuristically in the framework of this research. [ABSTRACT FROM AUTHOR]

For decades manganese steel casts have been most used materials for manufacturing elements subjected to impact and high stress abrasion. These materials are used in countless industrial applications that involve crushing of raw material by impact. Some of most important characteristics of manganese cast steels are work-hardening and high strength. Opposite from manganese steels, highly alloyed white cast irons are materials with high amount of hard carbide phases that shows better abrasion resistance but have lower strength and impact energy. Aim of this paper is to investigate possibilities to reduce costs and maintenance periods by implementing bimetallic materials. [ABSTRACT FROM AUTHOR]

The goal of the paper is to present an outline of different modeling approach at determining of backward extrusion force on AlCu5PbBi material and to compare them with experimental obtained results. Stochastic modeling in the paper is based on the statistic processing of central composite experimental design i.e. in this investigations central composite circumscribed (CCC) design. The numerical modeling is based on the finite element method (FEM) using ABAQUS 6.4.1. Explicit software. [ABSTRACT FROM AUTHOR]
