MICROSTRUCTURE AND PROPERTIES OF HIGH BORON BEARING STEEL S.Y.Chen1,C.S.Liu1,Q.K.Cai1,B.Yu1,Z.T.Wang1 (1.School of Materials and Metallurgy,Northeastern University,Shenyang 110006,China) Abstract:High boron bearing steel, in which boron homogeneously distributed, was successfullyproduced in the vacuum induction furnace. The microstructural observations of castand hot rolled steels showed......
Structure and property of mesoporous molybdenum/carbon co-doped brookite titania L? Xiao-meng(吕晓萌)1, LIU Jun(刘 军)2, ZHANG Hui(张 辉)1, DING Jian-lin(丁建林)1, XIE Ji-min(谢吉民)1 1. School of Chemistry... brookite TiO2. Key words: co-doping; brookite titania; photocatalysis ......
bearing capacity of strip footings on slope CHEN Chang-fu(陈昌富), DONG Wu-zhong(董武忠), TANG Yan-zhe(唐谚哲) (Institute of Geotechnical Engineering, Hunan University, Changsha 410082, China) Abstract: The influence of earthquake forces on ultimate bearing capacity of foundations on sloping ground was studied. A solution to seismic ultimate bearing capacity of strip footings on slope was obtained......
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......

modifiers (CaO and TiO2) were investigated. In addition, the depleted slag and cobalt-bearing alloy were characterized by X-ray diffraction, scanning electron microscopy and energy dispersive...; and the cobalt-bearing alloy mainly contained metallic copper, Fe-Co-Cu alloys and a small amount of sulfide. Key words: converter slag; cobalt recovery; reduction smelting; slag modifier; cobalt......
point in un-dripped slag. Also, MgO could form the solid solution of FeO-MgO, in which the melting point of solid solution increased with increased amount of MgO [15]. Figure 5 Effect of MgO bearing... compressive strengths in the fluxed-pellets with different category MgO bearing additives. The slag or gangue also has effects on the compressive strength of fluxed-pellets with different category......
reaction, and with the increase of basicity of slag, the limitation of deoxidation was decreased. The limitation of deoxidation is the lowest for the slag with basicity of 2.0. Under the conditions... of oxygen in the metal phase is the rate-controlling step, and the slag composition has no effect on the equilibrium time of deoxidation. Based on this finding, the optimized slag composition is designed......
