Hot Metal Desulphurization | Carmeuse

Desulphurization of hot metal is the most economic process for removing sulphur before charging to the BOF. Metallic Magnesium is the most effective reagent for desulphurization; calcium oxide is the most costeffective solution and the formed sulfides are very stable. Carmeuse provides fluidised milled lime, aimed at improving free flow and ...

EPA1

The agent based on magnesium for desulphurisation of iron melts is characterised by the fact the magnesium component is included in an alloy together with other alloy components which reduce the magnesium vapour pressure and/or act as deoxidisers. The magnesium component is separated from the others as an independent alloy, and is introduced into the melt according to the coinjection principle.

Steelmaking

The hot metal and slag are separated via a refractory lined runner system and directed to the hot metal torpedo ladle and the slag ladle. Other carbon carriers, such as coal, oil, gas or specially prepared old plastic are also injected into the blast furnace as an alternative to coke in order to optimise the process and reduce production costs.

Slag optimisation considering iron loss and sulphide ...

The slag in the hot metal desulphurisation (HMD) process should have a high sulphide capacity to capture the sulphur and a low viscosity to minimise the iron loss; in particular the emulsion loss. Although the slag composition changes during the HMD process as a result of reagent injection, the initial slag from the blast furnace (BF) is still ...

VOCATIONAL TRAINING REPORT

Jul 14, 2015 · HOT METAL DESULPHURISATION Sulphur is mainly present in the iron ore and in the coal. Reducing the sulphur content to less than % in the blast furnace is difficult from an economical standpoint. As the steel quality often requires a sulphur content of %, the hot metal must be desulphurized in another way.
