For the sake of difficulties with changes of the slags absolute viscosity in blast furnace raised of contents of titanium compounds, examinations of this physical quantity were undertaken studies. The main objective of works was the determine of titanium and alkalies compounds on the dynamic viscosity of synthetic blast furnace primary and final slags in the multicomponent systems. Practical studies have been realize on concentric cylinders rotation viscometer methods. Range of temperatures for primary slags: 1200-1300 degrees C, for final slags: 1400-1500 degrees C. The following slags systems were being studies: CaO-SiO(2)-Al(2)O(3)-MgO-FeO-TiO(2)-(K(2)O+Na(2)O) and CaO-SiO(2)-Al(2)O(3)-MgO-TiO(2)-(K(2)O+Na(2)O).
