AB  - Aluminothermic welding has been used to connect railway rails for over a century. This technique has the advantages of flexibility, weld compactness, and simplicity. External energy is not required for the procedure. Exothermic heat is produced by chemical reactions of aluminothermic elements. To create a quality welded connection, the mold and pouring system must provide uniform pouring of hot steel
without turbulence, even heat dissipation or cooling, and an acceptable micro and macro structure of steel free of internal and external faults. The design of the mould was constantly changing, necessitating costly industrial experimentation. As a result, the mould's design was constantly evolving, necessitating the use of costly experimental procedures in industrial settings. The latest iteration of the model the
casting cavity was improved by adding hoes in the sand and putting rails on both sides in order to more aquratly simuate heat transfer. Software programs are emulating conventional casting procedures for thermite steel casting in welded railway connections to save money and effort on costly and timeconsuming industrial testing. For the 49E1 rail, NovaFlow & Solid CV were utilized to simulate casting thermite steel in the mould cavity or weld junction.

AB  - Aluminothermic welding has been used to connect railway rails for over a century. This method has several advantages, including its versatility, the tightness of the weld it creates, and its ease of execution. To complete the procedure, no further power source is necessary. The design of the mold with the pouring system, which should ensure even pouring of thermal steel without turbulence, then even heat dissipation or cooling to obtain an appropriat  micro and acro structure of steel free of internal and external defects, is one of several factors that contribute to a quality welded joint. As a result, costly experimental techniques in industrial settings were necessary to keep up with the ever-changing mould design. The model design was upgraded in comparison to the previous version [1], and will be imroved even further.The two sets of solid steel rails put on either side of the casting mould will be adjusted as heating media within the mould material category in the future, bringing the model closer to reality. As a result, cooling and heating temperatures will be more evenly distributed. Stress and strain modeling were performed to the preheated model to provide a more complete understanding of how shrinkage is related to stress. In future iterations of the model, we will either move the heat source to its right place approximately 40 cm above ground or adjust the temperature, diameter, and gas at the current site to more exactly reproduce real-life circumstances. Furthermore, during simulation setup, the
replace material function may be used to model a new component that represents the divider that will be changed between air and silica sand material at the end of
prehearing. Software programs are being used to simulate conventional casting procedures that may be used in the casting of thermite steel during the fabrication
of welded railway connections in order to prevent costly and time-consuming
industrial experimentation. The NovaFlow & Solid CV software suite [2] was used

AB  - Mould powder is essential for the reliable operation of the continuous casting system and the quality
of the cast steel. The very responsible roles of mould powder are fulfilled by selecting combinations
of components that affect physicochemical properties of the resulting liquid slag, which lubricate the
walls among the crystallizer and slab. The contribution of mould powder refers to the range of
melting temperature and speed and the viscosity of glassy or crystalline slag and formation
temperature. These connections are the research subject in this paper, emphasizing the functional
dependence of viscosity and liquidus temperature of mould powder with its material composition.
This research investigates the impact of basicity, alkali oxides (Na2O and K2O), and carbon-free
content on viscosity and liquidus temperature of mould powder in the continuous casting process.
The liquidus temperature of mould powder was obtained empirically after a year of experimental
examination, and viscosity was determined using several models. Based on experimental
investigation, we show empirical parameters for equitation of liquidus temperature of mould
powder. Also, using established equations, we presented isolines for viscosity and liquidus
temperature with experimental parameters.

AB  - U radu je prikazana nova tehnologija aluminotermijskog zavarivanja (AT) prelaznih šina 49E1 na 60E1(EN 13674-1:2005.), oslonjena na potpuno nove materijale. Ona se odnosi na pešćane kalupe kod kojih su oblik i dimenzije ulivnog sistema projektovani tako da mogu odgovoriti svim zahtevima za postizanje zavarenih spojeva zadatog kvaliteta. Da bi ovaj zahtev bio u potpunosti ispunjen, projektovana je, takođe, AT smeša, čijom se aktivacijom dobija termitni čelik za ispunu, sa temperaturom izlivanja koja obezbeđuje optimalnu livkost metala, kao i viskoznost troske. U radu su zatim prikazani rezultati ispitivanja probnih prelaznih zavarenih spojeva, shodno standardima JŽS.Z2.610 i EN 14730-1:2012, a odnose se na utvrđivanje mehaničkih svojstava zavarenih spojeva, makrostruktirnih i mikrostrukturnih karakteristika, homogenosti i hemijskog sastava termitnog čelika za ispunu. Dobijeni rezultati pokazuju da je primenjena tehnologija optimalna, jer obezbeđuje upotrebu ove tehnologije u industrijskim uslovima na železnici.

It refers to sand molds in which the shape and dimensions of the inflow system are designed to meet all requirements for achieving welded joints of a given quality. The AT mixture was also designed to fulfill those requests; resulting liquid steel has a casting temperature that ensures optimal castability of the metal and slag viscosity. The paper presents the test results of the transients welded joints, following the standards JŽS.Z2.610 and EN 14730-1: 2012, and relates to the determination of mechanical properties of welded joints macrostructural and microstructural characteristics, homogeneity, and chemical composition of thermite steel. The obtained results show that the applied technology is optimal because it ensures the use of this technology in industrial conditions on the railway.

AB  - Simulating the furnace processes can lead to the minimal energy loses and optimal temperature distribution through the system. Freeze lining is a result of balance between the heat input from liquid bath and heat removal from outer layer. In that manner, solid slag crust is formed with good mechanical properties. At this paper freeze lining for the plasma smelting process was simulated using COMSOL software package. For smelting material corundum with the addition of other materials was used. Smelting is possible if the heat balance is properly calculated. Colling rate will control the layer thickness and inner temperature.

AB  - The analysis of material and energy balance can be done using concept of exergy, which is
a measure of available energy in the system [1]. Exergy losses indicate the place of
degradation in the process; thus, it implies improving of selected process.
The aluminothermic reduction process is an attractive method for immobilization of
hazardous waste, and for utilization of valuable elements from the waste [2]. The exergy
calculation relies on the material and energy balance calculation and standard chemical
exergy of the elements. For the purpose of material, energy, and exergy balance calculation
discrete non-commercial software was developed [3]. The waste materials used in these
calculations are Electric-arc furnace dust (EAFD, mostly Fe and Zn oxides) and the Mill
scale (mostly Fe oxides) [4].
Calculated exergy efficiency for aluminothermic processing of waste was 94.6%. All the
heat released by exothermic reactions was used for producing the iron, the slag and the
crude ZnO dust. Comparing to the conventional carbothermic reduction process in the DC
electric-arc furnace with the same materials (for which exergy efficiency was 56.5%) this
is much higher. The irreversible exergy losses of the aluminothermic process are 398.2
kWh/t of produced iron. The further processing of slag and dust is required, as well as in
the case of the carbothermic reduction process, so that the real value of exergy efficiency
of the process will be somewhat lower than the calculated.

AB  - Simulating the reactions in a complex system can lead to self-sustaining and energy efficient treatment of wastes in recycling promoting manner. In this contribution, the synergic combination of electric arc furnace dust (EAFD), mill scale, and secondary aluminum, in a form of waste foil, was researched aiming to use exothermal energy of reactions and to obtain environmentally favorable products. The secondary aluminum in the form of foil was prepared in different ways in order to develop aluminum surface and to be suitable for aluminothermic reactions. The commercial aluminum powder was used to determine optimal conditions using full factorial experiment design. After that, research was performed on aluminothermic reactions with the aluminum powder obtained from secondary aluminum foils. Results show that the secondary aluminum can be successfully used for a treatment of oxides bearing hazardous wastes in an energy efficient and environmentally friendly manner. The comparative life-cycle assessment revealed several advantages of using the secondary aluminum foil as a reduction agent compared to the conventional recycling of the secondary aluminum foil.

These metallurgical wastes consist of a many different phases and elements, making the reaction process complex. Thermo-chemical analysis of the reactions in metal, slag, and gas phases was done, and used for modeling of the mixture composition and energy consumption required for smelting. Modelling was performed with the software named RikiAlC. The crude ZnO, slag, and metal phase were analyzed using the atomic absorption spectrometry (AAS), the optical emission spectrometry with inductively coupled plasma (ICP-OES), the X-ray diffraction (XRD), the scanning electron microscopy (SEM) equipped with energy dispersive spectrometry (EDS), and reflected and transmitted light microscopy. Also, in order to follow the behavior of this process the exhausted gases were monitored. The synergetic effects of the designed mixture may be recognized in minimizing energy consumption for the smelting process, improving the product yield efficiency, and reducing the negative environmental effects.

AB  - The objects of this investigation were the comparative kinetic analysis of the NiO and NiCl2 reduction by hydrogen during an induction period and elimination of the calcination during the synthesis of Ni/Al2O3 catalysts. The effect of temperature and time on NiO and NiCl2 reduction degrees was studied. Avrami I equation was selected as the most favorable kinetic model and used to determine activation energy of the NiO and NiCl2 reduction for the investigated temperature range (623-923 K) and time intervals (1-5 minutes). The investigation enabled reaching conclusions about the reaction ability and rate of the reduction processes. Afterward, Ni/Al2O3 catalysts were obtained by using oxide and chloride precursor for Ni. The catalysts were supported on alumina-based foam and prepared via aerosol route. Properties of the samples before and after low-temperature hydrogen reduction (633 K) were compared. Obtained results indicated that the synthesis of Ni/Al2O3 catalysts can be more efficient if chloride precursor for Ni is directly reduced by hydrogen during the synthesis process, without the calcination step. In addition, Ni-Pd/Al2O3 catalysts with different metal content were prepared by using chloride precursors. Lower reduction temperature was utilized and the chlorides were almost completely reduced at 533 K.

AB  - Understanding the reaction thermochemistry as well as formatting the empirical data about element distribution in gas-metal-slag phases is essential for creating a good model for aluminothermic and carbothermic reaction. In this paper modeling of material and energy balance of these reactions is described with the algorithm. The software, based on this model is basically made for production of high purity ferro alloys through aluminothermic process and then extended for some carbothermic process. Model validation is demonstrated with production of FeTi, FeW, FeB and FeMo in aluminothermic and reduction of mill scale, pyrite cinders and magnetite fines in carbothermic process.
