MICROSTRUCTURAL CHARACTERIZATION OF FINE WASTE COLLECTOR FOR USE AS REINFORCEMENT IN COMPOSITE MATERIALS

Resumen

A characterization is presented of the waste obtained in collector sleeves of electric furnaces, called Fine Waste Collector (FWCs), during the ferroalloy production process in order to evaluate the possibilities of use as reinforcement of metal matrix composite materials. The characterization
of the particulate material was carried out through a granulometric classification, in addition with techniques of Optical Microscopy (OM), Scanning Electronic Microscopy (SEM) and chemical microanalysis by EDS, with the purpose of determining size, morphology and elementary chemical composition of the particles, main variables in the evaluation of a particulate material and its use as reinforcement. The results show the presence of mostly spherical morphology particles in a range of size <45 μm, in addition to its chemical composition the presence of important oxides mainly of Mn and Si, typical of the slag of the industrial process is observed. Given the characteristics of the fines, a potential reinforcement for the development of composite materials can be considered.

Palabras Clave: Characterization, waste, reinforcement, oxide, metal matrix.
