摘要
The effects of MgO/Al_(2)O_(3)and CaO/SiO_(2)ratios on the viscosity,break-point temperature,and viscous activation energy of a high titanium-bearing slag were studied.The results showed that both the viscosity and the break-point temperature of the slag decreased with the MgO/Al_(2)O_(3)ratio increasing from 0.50 to 0.65,the viscous activation energy decreased gradually,and the thermal stability became better.In addition,with an increase in CaO/SiO_(2)ratio from 1.12 to 1.22,the main viscous units in the slag depolymerized and the viscosity of slag decreased.However,the break-point temperature of slag showed an increasing tendency.The viscous activation energy decreased gradually and the thermal stability became better.The basic phase in the experimental high titanium-bearing slag was pyroxene,and its amount increased with increasing the MgO/Al_(2)O_(3)ratio while decreased with increasing the CaO/SiO_(2)ratio.
