Opis:: A foundry plant as a manufacturing system operates in accordance with the methods and principles making up the entire process of casting production, involving the use of machines and installations. One of the factors transforming the foundry plant’s static structure into the dynamic – processing structure is the compressed air. Practically each procedure making up the casting manufacturing process involves compressed air. Its sources include compressor machines connected to the receiving tanks, making up the compressed air transport installation. Two major aspects are to be addressed in compressed air management: the engineering and economic ones. The engineering aspect involves the manufacturing of compressed air with the required quality features and in the amount balancing its demand, whilst the economic aspect is associated with cost minimisation. This paper investigates the engineering aspects: air quality, with the main focus on air treatment processes to satisfy the constructional and operational requirements of air receivers present in the casting processes.

Opis:: There are many different casting technologies and their selection depends on the criteria to be met by a cast made. One of the less frequently used precision casting technology is a technology that uses gypsum block forms. From many years are available pre-mixed gypsum for the various alloys, and mold making technology itself can be based on melted wax models or models permanent removed from the mold after hardening the gypsum mix. In case of use permanent models to produce them may be used various types of flexible materials. This solution allows you to make complicated models that can be removed from the mold only by the fact that they are flexible and at the same time capable of large elastic deformations.

Opis:: The paper presents some aspects of the theory and technology of high quality silumin castings in metal molds cooled pointed with water mist stream. The results of the work relate to improvement of the properties of silumin casts by affecting the cooling of the liquid silumin in gravity cast in metal mold and the possibility of controlling the solidification and crystallization of the casting. The high efficiency required from the cooling system is a consequence of an optimal selection of parameters of the generated mist and the maximum use of the phenomenon of water droplets evaporation on the surface of the cooled mold. The study showed that sequential spot cooling with use of water mist, characterized by a wide range of control means and a high maximum heat transfer efficiency, enables to control the flow of heat between the casting and the mold and it allows for a layered solidification leading to the realization of the entire cast solidification in the expected way: directional or simultaneous. Consequently, the results are: improvement of the quality of the castings as a result of the elimination of defects and significant reduction in shrinkage porosity in the casting, an increase of the homogeneity and fineness of the microstructure, about 25% increase in the mechanical properties.

Opis:: Presented are results of a preliminary research on determining a possibility to use microwave radiation for drying casting protective coatings applied on patterns used in the lost foam technology. Taken were measurements of permittivity ε_r and loss factor tgδ at 2.45 GHz, as well as attempts were made of microwave drying of a protective coating based on aluminium silicates, applied on shapes of foamed polystyrene and rigid polymeric foam. Time and results of microwave drying were compared with the results obtained by drying at 50 °C by the traditional method commonly used for removing water from protective coatings. Analysis of the obtained drying kinetics curves demonstrated that selection of proper operation parameters of microwave equipment permits the drying time to be significantly shortened. Depending on kind of the pattern material, drying process of a protective coating runs in a different way, resulting in obtaining different quality of the dried coating.

Opis:: The paper presents a semi-industrial reactor designed for utilisation of waste moulds and cores made of thermosetting moulding sands by microwave incinerating. It was found that a possibility exists of effective incinerating residues of this kind waste cores or moulds left after casting. The research evidences that the apparatus permits effective control of the applied microwave heating process. Preliminary tests of microwave heating indicated that incinerating waste moulds and cores made of industrially used moulding sands based on phenolic-formaldehyde resins is an effective method of their utilization. Application of microwave heating for incinerating waste moulds and cores containing synthetic resins as binders guarantees significant and measurable economical benefits resulting from reduced process time.

Opis:: The work presents the research results of the influence of the selected technological factors on the improvement of bimetallic castings alloy steel-silumin. The following alloy steel grades were used for the research: X6CrNiTi18-10, X39Cr13 and HS6-5-2. The sets of the mentioned steel grades were alphinated in silumin AlSi5 and were poured with this silumin or complex silumin AlSi5Ni5Cu4MgCrMoWV into the casting mold obtaining bimetallic castings as a result. Moreover, the following technological factors of the process of bimetallic casting production were analyzed: the time from removing of the set from the alphinizing bath till pouring it with the silumin into the casting mold “τ_p”, the temperature of the initial heating of the casting mold “t_2,0” and the temperature of the silumin for pouring of the casting mold “t_z”. It follows from the presented results that the best connecting quality of the analyzed castings is obtained when using: the possible short time “τ_p” and low temperature values “t_2,0” and “t_z”.

Opis:: W artykule przedstawiono propozycję obniżenia energochłonności wykonania półfabrykatów elementów przekładni planetarnej dzięki zastosowaniu technologii odlewniczej. W pierwszej kolejności dokonano analizy ilości skrawanego materiału dla wytwarzanych elementów w technologii wytaczania z pełnej bryły oraz dla surowych odlewów. Następnie opracowana została technologia odlewania poszczególnych elementów, dla której oprzyrządowanie wykonano przy zastosowaniu metod szybkiego prototypowania. Efektem prowadzonych prac było uzyskanie serii odlewów prototypowych, przeznaczonych do testów eksploatacyjnych oraz uruchomienie produkcji analizowanych podzespołów przekładni planetarnej.
The article presents a proposal for reduced energy consumption level when making semi-finished components of the planetary gear by casting technology. First, an analysis was made of the material volume removed from elements machined by boring from a full block as compared with raw castings. Then the casting technology was developed for different elements, for which tooling was made by the rapid prototyping technique. The result of the work was obtaining a series of prototype castings intended for field testing, and launching the production of the analysed components of the planetary gear.
