“…The following figure shows a calculator that facilitates calculating the load of charge (Figure 3). [15] The application contains an interesting appendix describing the determination of process parameters and end properties in copper production [16,17]. You can find here not only information on the processes of alloying, refining or the machining process of a given material.…”

The study contains a description of the use of IT material base in foundry, refining and metallurgy processes. The program is an extension of applications for the assessment of physicochemical and refining properties of metallurgical slags and process base related to the production of brass. However, the functionality of this part is related to the assessment of the harmfulness of the use of specific substances in both laboratory and industrial processes. Thanks to the simple search interface, the user can get quick information about the dangers that can be carried by substances used by him. In addition, you can also check what protection measures should be used when working with the substances in question. The program also draws attention to the utilization of waste materials after production and research processes.

“…In order to perform tests on metal alloys, it becomes necessary to use a tool that makes it easier to calculate the charge of load necessary to obtain the alloy with the desired composition. The original program and method was presented at the [18]. With its help, it is possible by means of appropriate formulas to determine the composition of the charge for alloys with an assumed amount of one, two or three elements in the system, with any number of input materials.…”

The article presents an integrated analytical and measurement system for evaluation of the properties of cast metals and alloys. The presented platform is an extension of the SLAG -PROP application with new modules, which allow to use information on metallurgical processes in an even more effective way, as well as to evaluate the finished product. In addition, the construction of a measuring station for the analysis of thermal processes taking place in a metal bath allows for precise observation of phenomena together with their appropriate interpretation. The article presents not only the cooling curves of certain copper alloys. The analysis also covered mechanical properties related to hardness, finished products depending on the mold in which the products were cast. In the literature one can find information about the mechanical properties of products in the improved state, usually after plastic or thermal treatment, omitting their properties obtained as a result of a naturally made casting. The article also presents the method of placing information in the database using a convenient graphical tool.

“…Among casting alloys, widely described in the scientific domestic and foreign literature [1][2][3][4], casting bronzes and brasses constitute one of the most important groups, used for many years and still developed, since they create certain technological problems [5][6]. Various copper-and zinc-based alloys developed and assessed under laboratory [4][5][6][7][8][9] and industrial conditions [10][11][12] indicate several advantageous properties. They also indicate different, both mechanical and technological properties and corrosion/erosion [13] resistance.…”

The ecological factor is very important in shaping properties of alloys. It leads to a limitation or elimination, from the surroundings, of harmful elements from the heavy metals group. The so-called eco-brasses group comprises common lead-free brasses containing 10 to 40% of zinc and arsenic brasses of a high dezincification resistance. Among standardized alloys, CW511L alloy ( acc. to EN standard) or MS-60 alloy (acc. to DIN) can be mentioned. Investigations were performed on two different kinds of metal charges: ingots cast by gravity and the ones obtained in the semi-continuous casting technology with using crystallizers. The casting quality was analysed on the basis of the microstructure images and mechanical properties. The investigations also concerned increasing the corrosion resistance of lead-free alloys. This resistance was determined by the dezincification tendency of alloys after the introduction of alloying additions, i.e. aluminium, arsenic and tin. The investigations focused on the fact that not only alloying additions but also the production methods of charge materials are essential for the quality of produced castings. The introduced additions of aluminium and tin in amounts: 0÷1.2 wt% decreased the dezincification tendency, while arsenic, already in the amount of 0.033 wt%, significantly stopped corrosion, limiting the dezincification process of lead-free CuZn37 brass. At higher arsenic contents, corrosion occurs only within the thin surface layer of the casting (20 µ).
