Abstract: The desulphurizing reaction of the blast furnace low titania slag under the condition of no external agitation is confirmed to be of a first order. The controlling step is the diffusion of S in slag. The measures to accelerate the rate of desulfurization are approached.

Key words: low titania slag, reaction rate, activation energy, diffusion
