Abstract
The distribution of sulfur existence in the mineral phase and occurrence in the low-titanium slag with different cooling methods (water cooling, air cooling, crucible cooling, and furnace cooling) were studied by XRD, EPMA and XPS. The results show that with the cooling rate decrease, the distribution of S changes from clustering dots to large sheet or surface, and the occurrence of S in the mineral phase transfers gradually from the vitreous, perovskite, merwinite and the intertwined phase of some mineral phases to the gehlenite. During the transfer, the velocity decreases with the increasing of the cooling rate. The S in the water cooling slag only exists in the form of SO32−and SO42−, while the occurrences of S in the air cooling slag, crucible cooling slag, and furnace cooling slag are S2−, SO32−and SO42−.
