Abstract
Molten iron is desulphurized by being brought into contact with a mixture of 15-30 per cent of soda ash, 30-80 of one or more of burnt lime, limestone and dolomite, burnt or raw, and 5-30 of fluorspar. The mixture may be used in a highly heated state and may be placed in a container into which the molten iron is poured. The treatment may be carried out in a ladle or in a container between the hot metal mixer and the converter, open-hearth and the electric furnace. In an example the mixture contains 35 per cent of limestone, 40 of soda ash and 25 of fluorspar.
