In this paper, pure metallic zinc was distilled under vacuum at different temperatures, and pure metallic lead was distilled under vacuum at different temperatures and holding times, the condensation law and microscopic morphology of the condensates were studied in a specially designed multi-stage condenser. The special multi-stage condenser also proved to be a better instrument. Theoretical analy...... hiện toàn bộ
Effect of Sound Waves on Decarburization Rate of Fe-C MeltMetallurgical and Materials Transactions B - Tập 49 - Trang 264-273 - 2017
Sergey V. Komarov, Masamichi Sano
Sound waves have the ability to propagate through a gas phase and, thus, to supply the acoustic energy from a sound generator to materials being processed. This offers an attractive tool, for example, for controlling the rates of interfacial reactions in steelmaking processes. This study investigates the kinetics of decarburization in molten Fe-C alloys, the surface of which was exposed to sound w...... hiện toàn bộ
Wetting Behavior of Mold Flux Droplet on Steel Substrate With or Without Interfacial ReactionMetallurgical and Materials Transactions B - Tập 48 - Trang 1943-1950 - 2017
Lejun Zhou, Jingwen Li, Wanlin Wang, Il Sohn
The slag entrapment in mold tends to cause severe defects on the slab surface, especially for casting steels containing active alloy elements such as Al, Ti, and Mn. The wetting behavior of molten mold flux on the initial solidified shell is considered to be a key factor to determine the entrapment of mold slag on the shell surface. Therefore, the wetting behavior of mold flux droplet on the steel...... hiện toàn bộ
Dissolution Behavior of Iron and Steel Materials in Liquid MagnesiumMetallurgical and Materials Transactions B - Tập 49 - Trang 3432-3443 - 2018
Yu-ki Taninouchi, Katsuhiro Nose, Toru H. Okabe
The dissolution of metallic elements from Fe and steel materials into pure liquid Mg was investigated with the aim of improving control of impurities in Mg during processes such as Mg-alloy production and Ti smelting. Pure Mg was melted between 1073 and 1323 K (800 and 1050 °C) for 24 to 96 hours in closed crucibles made of pure Fe, low-carbon steel, or austenitic stainless steel SUS316. From the ...... hiện toàn bộ
Effect of Gas Atmosphere on Carbothermal Reduction and Nitridation of Titanium DioxideMetallurgical and Materials Transactions B - Tập 43 Số 1 - Trang 73-81 - 2012
Rezan, Sheikh A., Zhang, Guangqing, Ostrovski, Oleg
This article examined the reduction/nitridation of rutile in the He-N2, Ar-N2, and He (Ar)-H2-N2 gas mixtures, as well as pure nitrogen, in the temperature-programmed and isothermal experiments in a fixed-bed reactor. The extents of reduction and nitridation were determined from the off gas composition and LECO analysis. The off-gas composition was monitored using the infrared sensor (CO, CO2, and...... hiện toàn bộ
Development of Computational Models for Coiling Process with the Belt WrapperMetallurgical and Materials Transactions B - Tập 47 - Trang 2699-2704 - 2016
Yonghui Park, Hyunchul Park
This study introduces coiling mechanism with the belt wrapper to understand a force equilibrium for successful coiling. By establishing a finite element (FE) model, strips were coiled 2 to 3 rotations by the belt wrapper on the sleeve without coiling tension T, then T was applied to the opposite side of the strips near the pinch roller, and the belt wrapper was removed from the strip coil at the s...... hiện toàn bộ
