Then, it flows... changes from square to round. For FetO-SiO2 slag whose surface tension reduces with the increase of SiO2 concentration, slag film flows up under the inflence of wettability. Then, it flows down under......

Oxidization mechanism in CaO-FeOx-SiO2 slag with high iron content ZHANG Lin-nan(张林楠), ZHANG Li(张 力), WANG Ming-yu(王明玉), SUI Zhi-tong(隋智通) (School of Materials and Metallurgy, Northeastern University, Shenyang 110004, China) Abstract: Oxidization mechanism in CaO-FeOx-SiO2 slag with high iron content was investigated by blowing oxygen into molten slag so as to oxidize Fe......
between different slags and steel [15]. The hydrogen permeability at the beginning of the process is described as a function of the thickness of the slag film and the cross-sectional area as ... the thickness of the slag film, which can be calculated from D2-D1. The hydrogen permeabilities of different slag samples, as illustrated in Fig.3, are calculated using Eq.(2). The results obtained......
