hot metal desulphurisation process

  • Hot metal desulphurisation plants Precision work for every requirement In modern integrated metallurgical plants producing high grade steels the hot metal desulphurisation takes place outside the blast furnace The desulphurisation process precedes the steel treatment in the converterThe hot metal desulphurisation process is located between the blast furnace process and the basic oxygen process This means that variations in hot metal quantities temperature and sulphur level and in the target steel sulphur level result in variations in the demands on the desulphurisation process Despite this many hot metal desulphurisation

  • total processed hot metal from the blast furnace During the desulphurisation process the hot metal is treated with injection of a reagent material normally calcium carbide or magnesium powder before the hot metal is transferred to the BOF When desulphurisationThe hot metal desulphurization process is an external pre treatment of iron It takes advantage of the high content of carbon which implies a low activity of oxygen A low activity of oxygen makes the desulphurization process more effective according the hot
