	1	A MATHEMATICAL MODEL FOR THE PROCESS OF MAGNETITE OXIDATION显示文摘The oxidation rate of magnetite concentrate is ery quick at the reaction beginning,but itbecomes muck slower when the reaction is conducted to a certain level because the productlayer on the micro particles resists the oxygen diffusion greatly This phenomena are provedthrough experiments.And a function is put forward to calculating the quivalent osmosingthickness of the product layer.Based on the function,a mathematical model is establishedfor the whole range reaction process of magnetite in pellets.It is proved that this model fitsthe real process very well under any condition.

	2	Kinetics of Reduction of Iron Oxide in CaO-SiO_2-Al_2O_3-Fe_tO Slags with Graphite Powder显示文摘The reduction rate of Fe_tO in CaO-SiO_2-Al_2O_3-Fe_tO slags with graphite powder has been determined in an alumina crucible at 1 673-1 823 K.The effects of temperature,slag basicity and Fe_tO content on the reduction rate have also been discussed.Test results show that the reduction rate increases with the increase of temperature or Fe_tO concentration in slags,and the reduction rate has a parabolic relation with slag simple basicity or optical basicity.The maximum reduction rate is observed around CaO/SiO_2 = l.5 of molten slags.The reaction order is 1.26 or 1.31,and the reduction activation energy is 126.8 or 129.7 kJ/mol respectively in regard to Fe_tO content or Fe_tO activity calculated by using regular solution model.The reduction rate of Fe_tO in CaO-SiO_2-Al_2O_3-Fe_tO slags with graphite powder is in the range of 0.15×10^(-4)- 0.86×10^(-4) mol-O/cm^2 · s.
