Abstract: In the rapidly evolving landscape of logistics and warehousing, efficient inventory management is one of the most important issues. Forklifts, as indispensable tools in these environments, play an essential role, especially in the movement of goods. [..] Read more

Abstract: This paper presents a multi-pallet loading problem, assuming that products are heterogenous, and pallet loading units can be stacked creating sandwich (SNDW) loading units. The research task is to support the optimal composition of products on pallet units using the available space at the maximum level, and fulfilling the constraints, such as the maximum weight, height and stability of multi-pallet units.

Abstract: <div>In the iron and steel industry large amounts of fine granular bulk material like iron ore fines, fluxes, foundry sands or residues from off-gas dedusting have to be handled. In storage, conveying and handling of such materials wall friction between the particles and the wall material is an important parameter. [..] Read more

Abstract: <div>Nowadays, steelmaking companies use numerical simulations as an advanced tool to optimize process parameters, reduce defects, and enhance product quality, aligning with the rising market demand for high-quality steel ingots. For more accurate simulations, it is essential to set the correct material properties, process parameters (such as flow rate and temperatures), heat transfer coefficient, as well as the suitable geometry and corresponding discretization.

Abstract: <div>Today, Li-ion batteries (LIBs) play a vital role in reducing the consumption of fossil fuels. With the increasing production of LIBs, it is crucial to consider their recycling after reaching their end-of-life. [..] Read more

Abstract: <div>Stainless steel production typically follows the duplex process, beginning with the electric arc furnace (EAF) and proceeding to the vacuum oxygen decarburizer (VOD) or argon oxygen decarburizer (AOD). The EAF's role is to melt the charge and heat it up for further processing, reducing tap-to-tap times through partial oxidation. [..] Read more

Obtaining the correct welding parameters to join thin stainless materials without causing visible defects is an extremely delicate process. [..] Read more

Abstract: In numerical process design, the heat transfer coefficient (HTC) is used to calculate the intensity of heat transfer at an interface, for example between dies and workpiece. In most finite element calculations for bulk metal forging, a constant HTC is currently assumed, as there is no complete understanding of the relationship between the heat transfer coefficient and its influencing variables (e.g. [..] Read more

Abstract: <div>Over the past twenty years, there has been a rising interest in heat-treatable 6xxx series aluminum alloys, primarily due to their impressive strength-to-weight ratio, excellent formability, and outstanding corrosion resistance characteristics [1]. In conventional manufacturing processes, those alloys are solution heat treated and artificially aged following a hot forging process [2]. [..] Read more

Abstract: <div>Designing processes for producing responsible structural elements from steel in the hot forging process requires knowledge of the relationship between the process parameters, the microstructure that is formed under the assumed deformation conditions as well as the quality and properties of the forgings. The analysis of the microstructure after deformation allows the identification of phenomena occurring during hot processing, such as work hardening, recovery and recrystallization. [..] Read more

Abstract: <div>The paper is focused on experimental research with the goal of enhancing cold mill capability by improving the currently used coolant setting (various types of emulsions) and cooling configuration (type of nozzle, nozzle position, distance and inclination angle of headers with respect to the roll).The experimental research was divided into two phases. The initial phase examined the impact of various emulsion types on cooling intensity. [..] Read more
