Dear James,
For blast furnace conditions a first approximation for the changes that Ti
would produce can be seen by looking at the CaO-SiO2-TiO2 liquid
equilibrium diagram.This is given in T Rosenqvist's "Principles of
Extractive Metallurgy" 1983 p 300, MacGraw-Hill. The diagram is taken from
A Muan and E.F. Osborn "Phase equilibria among oxides in steelmaking" 1965
Addison-Wesley, Reading MA.
The effect is likely to actually be a reduction in the liquidus temperature
given a 'normal' blast furnace slag composition (See pages 296 & 299 of
Rosenqvist).
