Analysis of cracks and coating in iron ore pellets by digital image processing
Autor: Thalita Dias Pinheiro Caldas, Karen Soares Augusto, Julio César Álvarez Iglesias, Sidnei Paciornik, Alei Leite Alcântara Domingues
Publikováno v: REM: International Engineering Journal, Vol 73, Iss 3, Pp 345-352 (2020)
Abstract The pelletizing process agglomerates ore fines previously considered as tailings and makes its application possible in the form of pellets. During the process, the pellets are subjected to various compressive forces and temperature changes,

Discrimination of pores and cracks in iron ore pellets using deep learning neural networks
Autor: Emanuella Tarciana Vicente Bezerra, Karen Soares Augusto, Sidnei Paciornik
Publikováno v: REM: International Engineering Journal, Vol 73, Iss 2, Pp 197-203 (2020)
Abstract The discrimination between pores and cracks is an important step in the microstructural analysis of iron ore pellets. While the porosity is fundamental during the reduction process in blast furnaces, cracks are strongly detrimental to the me

Porosity Characterization of Iron Ore Pellets by X-Ray Microtomography
Autor: Karen Soares Augusto, Sidnei Paciornik
Publikováno v: Materials Research, Vol 21, Iss 2 (2018)
This work proposes a three-dimensional methodology to characterize porosity in iron ore pellets by X-ray Microtomography (microCT). An image analysis routine was developed to discriminate and quantify open/closed porosity. The results were compared t
