Experimental investigation and numerical modeling of strength properties of iron ore sinter based on pilot-scale pot tests and X-ray computed tomography

Journal of Materials Research and Technology, 2020
One of the most concerned quality in iron ore thermal agglomeration process is the mechanical strength of sinter and thus the size degradation of sinter product which occurs during transportation could be minimized.

A Study of a Two-Phase Heat Transfer Mechanism in a Vertical Sintering Cooling Furnace

Energies
In order to explore the law of gas–solid countercurrent cooling heat transfer in a vertical sinter cooling furnace at a high temperature, based on the Euler model and the local non-thermodynamic equilibrium theory, an exergy efficiency model was built to

A Study on Analysis of Sinter Microstructure and Phase Morphology

Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2021
Sinter is a blast furnace input material obtained by heating to 900-1200 oC without full melting and adhering to each other with superficial melting. It is considered as a multi-phase material with its sinter heterogeneous microstructure. In general, the

Formation of a nano-porous structured Cu layer by selective etching of a brass layer and sinter-bonding to achieve direct Cu–Cu bonding

Journal of Materials Research and Technology
A nano porous structured (NPS) Cu layer was fabricated by a Zn plating-annealing-selective etching process. Furthermore, sinter-bonding was performed by thermocompression after forming the NPS Cu layer instead of the conventional paste sinter-bonding ...
