through synthetic slag additions as well as final adjustments to the chemical composition of the steel (Kor and Glaws, 1998). During tapping of the steel from the primary vessel (typically a BOF) or arcing at the ladle furnace, nitrogen (N) in the air dissolves into the steel. Many of the alloys and
Phase equilibria of the Al2O3–CaO–FeO–SiO2–V2O3 system in synthetic slag mixtures simulating coal–petcoke slag chemistry at 1500 °C in an oxygen partial pressure of 10–8 atm were investigated by a series of quench experiments. Quenched samples were analyzed by inductively coupled plasma optical emission spectrometry (ICP), Xray diffractometry (XRD), transmission electron ...

· 4. Slag conditioner is stable and free from any kind of dust. 5. Slag conditioner is easy to handle in steel making process 6. It requires some kind of additive to make special kind of steel.
Calcium AluminateThe Refining Slag refers to a technique in which the raw materials are mixed at a certain ratio and particle size, heated at a temperature lower than the melting point of the raw materials, and the raw materials are sintered together and then broken into particle sizes. The main components are CaOCaF2 group, CaOAl2O3 group ...
· The difference was between adding steelmaking slag, FeO, or metallic iron to artificial seawater on sulfides has been investigated (Hayashi et al., 2014). In the case of slag, Fe in the slag reacted with the sulfide irons to form sulfides of iron, known as troilite (FeS) and pyrite (FeS 2 ).
with Steelmaking Slag to Artificial Tidal Flat † HONDA Hideki*1 TSUCHIDA Takashi*2 Abstract: In order to effectively use dredged soil, improved dredged soil which is mixed with steelmaking slag has been developed. Intended appliion areas of the improved soil are tidelands, dredging hollows and reclamation materials.
The primary USES of silicon slag can be used as deoxidizer and refining of industrial grade silicon, silicon slag as deoxidizer can reduce costs, increase profits, part of silicon slag containing silicon components can also be used for the purifiion of industrial silicon, silicon slag in the field of DNA is also a "star", because its price is low and contains silicon,Steel makers prefer ...
amount of stainless steel AOD slag is added [6]. Faraone . et al. [7] claim that steelmaking slag is not an inert material whereas Setién . et al. [8] observed that LM slag developed cementitious properties when it reacted with atmospheric moisture. Rodriguez . et al.[9] used LM slag in masonry mortars as a partial replacement for sand and ...

Slag carryover and the production of clean steel Pistorius Synopsis For effective steel refining in the ladle (secondary steelmaking) the amount of steelmaking slag that is transferred from primary steelmaking must be limited, because the steelmaking slag contains iron oxide, manganese oxide, and phosphorus oxide.
White slag practices have been instituted in many silicon killed shops that reduce FeO levels in the slag to less than 1% which aids in the removal of sulfur from the liquid steel. While some have claimed to "invent" the white slag practice, a reference can be found in the 1951 edition of Making Shaping and Treating of Steel, pg. 517518.
High Carbon Ferro Silicon,replacement for FeSi in the amount of other expensive deoxidizer, and operate conveniently and do not increase equipment, not only easily control element contont of molten steel,but also no impurity,which is highly praised by returned customers.

Improper composition of Synthetic Slags is detrimental for the quality of steel as it can lead to harmful reversion of P, S, and unwanted oxides.
by synthetic slag plus strong stirring/mixing Nowadays, a range of secondary steelmaking facilities is available for three main reasons: • They permit wider range of steels to tighter and more demanding specifiions; • CC demands much tighter scheduling – secondary steelmaking acts as a .
the steel with synthetic slag. 2. Problem Formulation To determine the influence, on the desulphurisation process, of the addition of titanium oxide in the calcium aluminate slag, we performed laboratory experiments, we treated the slag with liquid synthetic slag obtained by melting the mixture consisting of limestone, aluminate slag and slag
