Enhanced recovery of high-purity Fe powder from iron-rich electrolytic manganese residue by slurry electrolysis
International Journal of Minerals, Metallurgy, and Materials - - 2024
Wenxing Cao, Jiancheng Shu, Jiaming Chen, Zihan Li, Songshan Zhou, Shushu Liao, Mengjun Chen, Yong Yang
Iron-rich electrolytic manganese residue (IREMR) is an industrial waste produced during the processing of electrolytic metal manganese, and it contains certain amounts of Fe and Mn resources and other heavy metals. In this study, the slurry electrolysis technique was used to recover high-purity Fe powder from IREMR. The effects of IREMR and H2SO4 mass ratio, current density, reaction temperature, ... hiện toàn bộ
Fitting function representation for strain fields and its application to the optimizing process
International Journal of Minerals, Metallurgy, and Materials - Tập 21 - Trang 556-562 - 2014
Kun Chen, Ke-jia Liu, Li-qun Wei, Yi-tao Yang
A fitted function method to describe the strain fields during forging was discussed to optimize the homogeneous distribution of strain in the axial forging zones during successive stretching. The results are verified by experiment and numerical simulation, and the deviations between experiment and simulation are less than 24%. Therefore, the fitted function method can be applied to optimize the st... hiện toàn bộ
Channel effect of the modified powdery mixture of ammonium nitrate and fuel oil
International Journal of Minerals, Metallurgy, and Materials - Tập 17 - Trang 519-525 - 2010
Chun-ping Wu, Lian-sheng Liu, Xu-guang Wang, Yong Liu, Yin-jun Wang
The modified powdery mixture of ammonium nitrate and fuel oil (MPANFO) is a new breed of industrial explosives developed years ago in China. As one of the important properties of an industrial explosive, the channel effect of MPANFO was reported in this paper. A series of experiments were conducted to determine the channel effect of MPANFO. The blasthole diameter range was estimated to avoid the c... hiện toàn bộ
Coordinated control of carbon and oxygen for ultra-low-carbon interstitial-free steel in a smelting process
International Journal of Minerals, Metallurgy, and Materials - Tập 22 - Trang 1252-1259 - 2015
Min Wang, Yan-ping Bao, Quan Yang, Li-hua Zhao, Lu Lin
Low residual-free-oxygen before final de-oxidation was beneficial to improving the cleanness of ultra-low-carbon steel. For ultra-low-carbon steel production, the coordinated control of carbon and oxygen is a precondition for achieving low residual oxygen during the Ruhrstahl Heraeus (RH) decarburization process. In this work, we studied the coordinated control of carbon and oxygen for ultra-low-c... hiện toàn bộ

Migration behaviors and kinetics of phosphorus during coal-based reduction of high-phosphorus oolitic iron ore
International Journal of Minerals, Metallurgy, and Materials - Tập 26 - Trang 938-945 - 2019
Yong-sheng Sun, Yan-feng Li, Yue-xin Han, Yan-jun Li
To understand the migration mechanisms of phosphorus (P) during coal-based reduction, a high-phosphorus oolitic iron ore was reduced by coal under various experimental conditions. The migration characteristics and kinetics of P were investigated by a field-emission electron probe microanalyzer (FE-EPMA) and using the basic principle of solid phase mass transfer, respectively. Experimental results ... hiện toàn bộ
Dissolution and diffusion of TiO2 in the CaO-Al2O3-SiO2 slag
International Journal of Minerals, Metallurgy, and Materials - Tập 21 - Trang 345-352 - 2014
Zhong-shan Ren, Xiao-jun Hu, Xin-mei Hou, Xiang-xin Xue, Kuo-chih Chou
The dissolution of TiO2 in the CaO-Al2O3-SiO2 slag under static conditions was studied in the temperature range from 1643 K to 1703 K. After TiO2 dissolved, the microstructure of the interface between TiO2 and the slag was observed by scanning electron microscopy, and the concentration profiles of Ti4+ and other ions across the TiO2/slag interfaces were analyzed by energy-dispersive X-ray spectros... hiện toàn bộ
Direct preparation of semi-solid billets by the semi-solid isothermal heat treatment for commercial cold-rolled ZL104 aluminum alloy
International Journal of Minerals, Metallurgy, and Materials - - 2021

Recent progress in the structure optimization and development of proton-conducting electrolyte materials for low-temperature solid oxide cells
International Journal of Minerals, Metallurgy, and Materials - - 2022
Jia Song, Yuvraj Y. Birdja, Deepak Pant, Zhiyuan Chen, Jan Vaes
This work reviews technologies that can be used to develop low-temperature solid oxide cells (LT-SOCs) and can be applied in fuel cells and electrolyzers operating at temperatures below 500°C, thus providing a more cost-effective alternative than conventional high-temperature SOCs. Two routes showing potential to reduce the operating temperature of SOCs to below 500°C are discussed. The first rout... hiện toàn bộ
Relationship between elements migration of α-AlFeMnSi phase and micro-galvanic corrosion sensitivity of Al—Zn—Mg alloy
International Journal of Minerals, Metallurgy, and Materials - Tập 30 - Trang 112-121 - 2022
Min Ao, Yucheng Ji, Pan Yi, Ni Li, Li Wang, Kui Xiao, Chaofang Dong
First principles calculations and scanning Kelvin probe force microscopy (SKPFM) were used to investigate the effect of elements migration of α-AlFeMnSi phase on micro-galvanic corrosion behavior of Al—Zn—Mg alloy. The simulation results showed that the average work function difference between the α-AlFeMnSi phase and Al matrix decreased from 0.232 to 0.065 eV due to the synchronous migration of e... hiện toàn bộ
