]. Clay vanadium mineral, like vanadium-titanium magnetite and vanadium-bearing stone coal, is an important resource for vanadium [2]. The extraction of vanadium from clay ore usually adopts roasting...] and LIAO et al [11] reported the biological process of vanadium-bearing stone coal using A. ferrooxidans. According to the literature, A. ferrooxidans could lower the toxicity of waste catalyst......

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......
and the hardness of the steel after the shortened heat treatments were measured. Finally the possibility to use these processes in industrial production is discussed. 关键词:bainite; bearing steel; dilatometry... treatment of throughhardening bearing grades in the lower bainitic range allows to adjust the mechanical properties of machine components to the later application, similar to those of martensitic......
Equilibrium between Slag and Molten Iron in the Direct Alloying of Steel with Nb2O5-Bearing Slag陈伟庆,周荣章,林宗彩摘 要:<正> Equilibrium between slag and molten iron at 1600℃ was investigated for the direct alloying of steel with Nb2O6-bearing slag. The activity of niobium oxide in the slag was measured. The αNb2O5 is in the range of 10-2-10-4. TheδNb2O5......
Research on Hydration of Steel Slag Cement Activatedwith Waterglass胡曙光摘 要:This paper studied the hydration and strength influence factors of Steel Slag Cement (SSC), such as the quantity of steel slag and slag and the dosage of additive. The results show that: (a) In the process of hydration of SSC,steel slag and slag activate each other; (b) Waterglass......
