Schrama, F.N.H. (author), Beunder, Elisabeth M. (author), van Boggelen, J.W.K. (author), Boom, R. (author), Yang, Y. (author)HIsarna is a smelting reduction ironmaking process that is currently in the pilot plant development phase. HIsarna produces hot metal with higher sulphur, lower phosphorus and manganese, almost no silicon and titanium and a lower temperature compared to the blast furnace. Because of that, desulphurisation of the HIsarna hot metal is one of the...conference paper 2017

Schrama, F.N.H. (author), Beunder, Elisabeth M. (author), Visser, H. (author), Boom, R. (author), Sietsma, J. (author), Yang, Y. (author)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 sulphides, that are formed during the desulphurisation process, to reach the slag phase thus...conference paper 2019

Schrama, F.N.H. (author), Beunder, Elisabeth M. (author), Visser, H. (author), Sietsma, J. (author), Boom, R. (author), Yang, Y. (author)Carbon may precipitate during the hot metal desulfurization (HMD) process as a result of carbon oversaturation because of temperature decrease. The precipitated carbon flakes form a layer between hot metal and slag. It is postulated that this carbon layer hampers desulfurization with magnesium by preventing MgS particles from reaching the...journal article 2019
