Modelling and Simulation of Drag Forces of Non-spherical Particles Moving Towards a Surface in Polymer Melt Flows
(Elsevier Science, 2017-07)
This work deals with the drag forces acting on non-spherical particles translating normal to a surface in a polymer melt in which the particle–surface distance is small compared with particle dimension in the flow direction. ...
Continuous production of metal matrix composites from the semisolid state
(2013-01-01)
Continuous strip metal matrix composite (MMC) casting of 0.3 mm diameter hard-drawn stainless steel (316L) wire in a quasi-eutectic SnPb (64Sn36Pb) matrix was performed by a two-roll melt drag processing (TRMDping) method, ...

Influência da alteração do layout do pote de zinco no arraste de Dross no material galvanizado a quente
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA METALÚRGICAPrograma de Pós-Graduação em Engenharia Metalúrgica, Materiais e de MinasUFMG, 2022-07-30)
The production of hot-dip galvanized steel has increasingly required in-depth knowledge of the phenomena involved in the interaction of the moving steel strip with the molten zinc bath. One of the biggest challenges is ...
Influence of pouring temperature and alloy additions on the quality of a semisolid material dragged during the continuous-casting strip processing of al-si a413
(2019-01-01)
Al–Si A413 treated and untreated alloys were cast and poured at approximately 720 ºC, 700 ºC, and 680 ºC in a cooling slope to obtain the semisolid material feeding the ceramic nozzle (150 cm 3 ) at the lower roll (single-roll ...
Determination of crustal anatexis conditions from thermodynamic modelling and zircon data: the case of the late triassic a And S-Type granites in the high Andes of Central Chile (~30°S)
(Universidad de Chile, 2022)
This thesis is focalized in the thermodynamic conditions that favor the generation of anatectic melts in different scenarios, and also as a study case, about the origin of crust-related plutons of the Late Triassic, in the ...
Modelamento matemático do escoamento de fluidos no processo RH para previsão da taxa de circulação do aço
(Universidade Federal de Minas GeraisUFMG, 2011-05-25)
The RH process is a refining process used in the production of interstitial free steels. In this process, vacuum and inert gas injection promote the refining reactions (removal of C, H and N). The vacuum chamber is connected ...
Manufacture of continuous metal matrix composite strip reinforced by particulate materials from the semisolid processing
(2019-01-01)
Strip casting is a new method of producing metal matrix composites. Two-roll melt dragged processing (TRMD-ing) and single-roll melt dragged processing (SRMD-ing) methods were used to study the manufacture of 2-mm-thick ...
Continuous production of a multi-filament reinforced metal matrix composite strip from the semisolid state
(2014-01-01)
Continuous metal matrix composite strip casting (MMCS-ing) composed of six 0.3-mm diameter annealed bare copper wires in a eutectic SnPb matrix was manufactured by a two-roll melt dragged processing (TRMD-ing) method at a ...
