The transformation process and the products of long term isothermal transformation around the kinetic B_s temperature(the bay temperature in TTT diagram)in Fe-C-Mo alloys have been investigated.It was found that,at the final stage of intermediate transformation,a kind of granular structure formed accompanying the growth of bainitic ferrite.In comparison with the carbide Mo_2C in the bainitic ferrite plates or blocks,the carbide m granular eutectoid has been determined to be cementite containing a tiny bit of molvbdenum,(Fe,Mo)_3C.

For slag system of CaO-SiO_2-Al_2O_3-MgO-V_2O_5,the time of V reduction to appro ch the dynamical equilibrium is about 6 h,the equilibrium time is not evidently influenced by the ratio CaO/SiO_2 and shortens with the increase of temperature.It the ratio of the weight of slag to that of iron bath is 1/2,CaO/SiO_2 0.8 and tomperature 1773 K.the maxium distribution coefficeent of V reduction is 32.4 and maxium recovery of V is 96.1%.
