(PDF) The Necessity of Hot Metal Desiliconization Process
A new process, SMP (slag minimum refining process), which consists of hot metal desiliconization and dephosphorization and decarburization in a LD converter has been studied in order to reduce the,(PDF) Hot metal desulphurisation simulator,Hot metal desulphurisation simulator Ville-V altteri Visuri *) and Petri Sulasalmi Process Metallurgy Research Unit, University of Oulu, PO Box 4300, FI-90014 University of Oulu, Finland.Process for desulfurization of molten hot metals - The Dow,,14/5/1991· One aspect of the present invention is directed to a process for desulfurizing molten hot metal, by injecting a desulfurization reagent into the molten hot metal using a carrier gas via a lance immersed in the molten hot metal; said desulfurization reagent comprising powdered or particulate magnesium nitride.Hot Metal Desulfurization_Steel Pipe knowledge_News_World,,Hot metal pre-desulfurization (the preliminary desulphuzation of hot metal) process methods of Hot Metal Desulfurization method are many, depending on the way stirring the molten iron way and desulfurization agent can be divided into: Spreading method, shake the container method, mechanical stirring, blowing stirring method injection method,Transition metal oxides for hot gas desulphurisation,,For the desulphurisation simulations the influence of temperature from 300°C to 1500°C on residual H 2 S level at a fixed pressure of 15 MPa was studied for each case, using the simulated coal gas as input stream. All simulations used 100% excess oxide, i.e. the amount of metal fed was twice the amount required to capture all sulphur.Sulphur removal in ironmaking and oxygen steelmaking,oxygen steelmaking process is reviewed. A sulphur balance is made for the steelmaking process of Tata Steel IJmuiden, the Netherlands. There are four stages where sulphur can be removed: in the blast furnace (BF), during hot metal (HM) pretreatment, in the converter and during the secondary metallurgy (SM) treatment. For sulphur removal a lowDesulfurization of steel [SubsTech],Desulfurization may be effectively conducted in the reducing slag stage of the steel making process in Electric-arc furnace. At this stage the oxidizing slag is removed and then lime flux is added to form basic slag with high CaO content. Deep desulfurization by slags may be achieved in ladle:JAMIPOL,Total Desulphurisation Management (TDSM) Hot Metal Desulphurisation (HMDS) Operation & Maintenance of desulphurisation (DS) plant services to the customers against cost guarantee model so that customers can concentrate on their core steel making process and leave the DS Operations & Maintenance services to JAMIPOL who has decades of experience in DS.Optimisation of hot metal desulphurisation slag in the CaO,,In this study, the effect of the hot metal desulphurisation slag chemistry on the separation of metal from slag was investigated for the varying hot metal desulphurisation conditions (e.g. BF slag carryover, the amount of CaO/Mg injected, hot metal temperature, etc.) via theoretical calculation and laboratory experiments.
