Desulfurization in Steelmaking - AF Chemicals

Thus, desulfurization (sulfur removal from liquid steel) is needed as a key process that is mainly achieved in ladles during secondary steelmaking. In Steel Desulfurization, several factors simultaneously effect the extent of sulfur removal from the molten steel: capacity/potential of the slag for sulfur removal; steel-slag reaction

Removal of Sulfur From Iron Ore with Physical and Chemical ...

Sulfur is present in iron ore in the form of sulfatic, pyritic (FeS 2) and other sulfurous mineral salts. This is an unwanted content as stated in the iron-steel industry. It should be removed from the environment with physical and chemical methods at the ore stage or the pot stage. While sulfate sulfur can be easily removed from the

REMOVAL OF SULFUR AND PHOSPHOROUS FROM IRON ORE ...

Sulfur removal can be performed using two main methods: conventional pyrometallurgical (smelting/converting) and hydrometallurgical (flotation/leaching or bioleaching).

Desulfurizing Steel: Magnesium is the Reagent of Choice

To satisfy low sulfur requirements for iron processed into steel, magnesium reagents in powder or granular form are used to remove sulfur via slag-liquid metal reactions done under reducing conditions, where sulfur is transferred out of the steel through the slag-metal interface, and into the slag. Slag is an

Removal of Phosphorous from Steel Produced by Melting ...

When steel is smelted in an arc furnace, the removal of sulfur is not the primary concern. However, when using pure metal batch, the reduction in sulfur content in the arc furnace is often ...

Sulphur in Steels – IspatGuru

23/09/2014· For high strength (HS) steel plates and for some special bar quality (SBQ) steel products, this may mean removing the S to a level of 0.005 % maximum. There are several methods which are widely used for achieving this level of S. Further, efficient removal of S from liquid steel or iron depends on specific metallurgical and thermodynamic conditions. Though these conditions may vary with the …

Desulfurization of steel [SubsTech]

31/05/2012· The most popular method of desulfurization is removal of sulfur from molten steel to the basic reducing slag. Basic slag is a slag containing mainly basic oxides: CaO, MgO, MnO, FeO. A typical basic slag consists of 35-60% CaO + MgO, 10-25% FeO, 15-30% SiO 2, 5-20% MnO. Transition of sulfur from steel to slag may be presented by the chemical equation: [S] + (CaO) = (CaS) + [O] The …
