This paper presents a study of the splashing phenomenon caused by the impingement of supersonic jets onto the slag–metal molten bath under real oxygen steelmaking conditions using numerical simulations. The validity of the mathematical model has been verified through different appliions. The time-sequenced occurrence process and generation mechanism of splashing are revealed, and the

May 31, 2012· Dr. Dmitri Kopeliovich Basic Oxygen Furnace (BOF) is a steel making furnace, in which molten pig iron and steel scrap convert into steel due to oxidizing action of oxygen blown into the melt under a basic slag.. The Basic Oxygen Process (Basic Oxygen Furnace, Basic Oxygen Steelmaking, Basic Oxygen Converter) is the most powerful and effective steel making method.

Steelmaking (BOS) vessel, i.e. in the LD-process. Slopping reduces process yields and may lead to discharge of pollutants to the surrounding environment. This thesis presents a study of the basics of the slopping phenomena in a top-blown BOS vessel and an investigation into local conditions causing slopping at SSAB
The inputs to the control model are the load data of the LD-KGC converter at the blow beginning and the collected data by the lance to 89% of oxygen blow. The results obtained in the present work were compared to the data measured in steelmaking. The semi-dynamic control model results agree well with data for LD-KGC converters.
He is business responsible for converter steelmaking covering hot metal treatment, LD converter as well as AOD converter projects. He joined Primetals in 2009 building up simulation group for finite element, CFD and logistic simulations.

The exhaust gas discharged from the converter furnace is the gas of high temperature (1,450°C) containing high concentration of CO (95%). The OG unit is an oxygen converter gas treatment system which is designed for the purpose of cooling this exhaust gas by burning it as little as possible, removing the dust contained in the exhaust gas at high concentration and recovering the gas as CO gas
Steel - Steel - Secondary steelmaking: An open-topped cylindrical container made of heavy steel plates and lined with refractory, the ladle is used for holding and transporting liquid steel. Here all secondary metallurgical work takes place, including deslagging and reslagging, electrical heating, chemical heating or cooling with scrap, powder injection or wire feeding, and stirring with gas
A mathematical model was developed to quantify the effects of different operational parameters on the nitrogen content of steel produced during oxygen steelmaking. The model predicts nitrogen removal by the CO produced during decarburization and how the final nitrogen content is affected by different process variables. These variables include the type of coolants used (scrap, direct reduced
Abstract. In a previous study by Sarkar et al. (Metall. Mater. Trans. B 46B:961 2015), a dynamic model of the LD steelmaking was developed.The prediction of the previous model (Sarkar et al. in Metall. Mater.Trans.

SAIL (Steel Authority of India Limited) Durgapur, India, has awarded SMS group a turnkey contract for the supply of three new 110-ton converters for its steelmaking plant No. 2 to replace the converters SMS group supplied 25 years ago.The new converters will be rated for ten percent more volume. Moreover, SMS group will supply secondary dust collecting systems for the three converters.
The reason adding this magnesium oxide containing flux is the refractory composing this the converter is easily eroded by steelmaking slags. Steelmaking slag contains such amount of iron oxide this easily eroded the refractor wall. The refractory wall is actually composed of magnesium oxide, so in order to treat chemical erosion, the magnesium
