Mica based coating for application in lost foam casting process
(Editura Stiintifica Fmr, Bucharest, 2012)
This paper presents the results of mechanical activation of filler based on mica and the influence on the quality of foundry coatings. The coating was applied for lining of evaporable model in Lost foam casting process. ...
Modeling of metallurgical properties of sinter mixtures of non-standard raw iron-bearing materials
(Editura Stiintifica Fmr, Bucharest, 2013)
Present paper represents a methodology for establishing a relationship between the composition of mixtures of iron-bearing non-standard dispersed raw materials for production of sinter and its most important metallurgical ...
Life extension of gears flank surfaces regenerated by hard facing
(Editura Stiintifica Fmr, Bucharest, 2013)
This paper contains the results of experimental analysis of fatigue endurance of used steel teeth regenerated by hard facing. The cylindrical spur gears were tested and compared with the newly made ones, oiler being ...

Possibility of carbon steel eafd solidification/stabilization in concrete
(Editura Stiintifica Fmr, Bucharest, 2013)
Steel scrap recycling is generally performed by direct smelting of scrap in an electric arc furnace, generating about 2% of dust per charge. Electric arc furnace dust (EAFD) is characterized as a hazardous material, due ...
Effects of additives on nickel (ii)-chloride hydrogen reduction for production of nanocomposite catalysts
(Editura Stiintifica Fmr, Bucharest, 2012)
Catalysts based on nickel, as active component, exhibit suitable properties in various heterogeneous catalysis processes; however, they quickly deactivate due to deposits formation during exploitation and sintering at ...
Characterization of microstructure and properties of hypereutectic al18wt%si alloys reinforced by 10%sic alloy
(Editura Stiintifica Fmr, Bucharest, 2012)
The aim of this work was to test the influence of various process parameters to obtain composite materials based on the Al18Wt%Si alloy with addition of 10Wt%SiC.For a comparative analysis purposes, the samples obtained ...
Economic insight into energents consumption in copper melting and refining plants of Serbia using the method of reduction to conditional fuel (coal equivalent)
(Editura Stiintifica Fmr, Bucharest, 2011)
Copper melting and refining include consumption of significant quantities of almost all kinds of conventional energents. Consumption is high in nominal as well as in specific form. This paper presents the analysis of ...
The mechanism and kinetics of the tungsten (vi)-oxide reduction in the vertical tube reactor
(Editura Stiintifica Fmr, Bucharest, 2012)
Presented study shows the analysis of the process of reduction of WO 3 powder with hydrogen in the vertical tube reactor, representing a new approach in comparison to the conventional methods in the horizontal tube reactor. ...
Reuse of metallurgical slag from the silicothermic magnesium production and secondary lead metallurgy
(Editura Stiintifica Fmr, Bucharest, 2012)
The feasibility study of using different kinds of slag as constituents in construction materials is presented in this paper. As possible materials, slag from silicothermic process of magnesium production is used in fresh ...
