To lower the iron losses of the hot metal desulphurisation (HMD) process, slag modifiers can be added to the slag. Slag modifiers decrease the apparent viscosity of the HMD slag. Most common slag modifiers in industry contain fluoride as a fluidiser.

In this PhD thesis, the desulphurisation in 21st century iron- and steelmaking is investigated. The current state of the art in sulphur removal in ironmaking and oxygen steelmaking is discussed (Part I of this thesis) and optimisation of the hot meta

Sulphur is considered one of the main impurities in steel. Hot metal desulphurisation serves as the main unit process for sulphur removal in the production of steel. The main objective of this thesis is to identify the relevant phenomena and attribut

In hot metal desulphurisation (HMD) the slag will hold the removed sulphur. However, the iron that is lost when the slag is skimmed off, accounts for the highest costs of the HMD process. These iron losses are lower when the slag has a lower viscosit

The optimal hot metal desulphurisation (HMD) slag is defined as a slag with a sufficient sulphur removal capacity and a low apparent viscosity (ηslag) which leads to low iron losses. In part I of this study, the fundamentals behind the optimal slag

Hot metal desulphurisation serves as the main unit process for removing sulphur in blast‐furnace based steelmaking. This study reviews the available body of literature on modelling hot metal desulphurisation to provide an in‐depth analysis of the

During the magnesium-lime co-injection process for hot metal desulphurisation, graphite can precipitate as a result of carbon oversaturation. The formed graphite is known to form a layer between the slag and the hot metal. This potentially blocks the

At the hot metal desulphurisation (HMD) stations of Tata Steel’s BOS plant in Port Talbot (UK), KAlF4 is injected together with magnesium in order to increase the fluidity of the slag and thus to decrease the iron loss. Although KAlF4 is successful
