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..., hematite, silica and calcium oxide in alumina crucible, heating in argon to 1380℃ and holding at this temperature for 1h. The crucible was taken out of furnace and the molten slag was immediately poured......
of heterogeneous titanium-bearing molten slag. By measuring the relationships among the viscosity, the shear stress and the shear rate of molten slags with different Ti C contents at different... indicated that, with increasing Ti C content, the viscosity of the molten slag tended to increase. If the Ti C content was less than 2wt%, the molten slag exhibited the Newtonian fluid behavior when......
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......
. Xingtai Iron and Steel Co. Ltd.摘 要:To use the potential heat of molten blast furnace slag completely,a CaO-Al2O3-SiO2system glass(MSG)was prepared from the molten industrial slag.The corresponding method proposed in this study utilized both slag and its potential heat,improving the production rate and avoiding the environmental pollution.Using appropriate......
