Sulphur and phosphorus is also diluted by the sponge iron. Because of use of sponge iron the trace elements in the steel made in the IF remains under control. Comparison with Electric Arc Furnace steel making process The comparison of the operating parameters of induction furnace with those of electric arc furnace is given in Table 1.
Steel is a metal alloy containing iron and carbon with other alloying elements mainly produced by the Basic Oxygen Furnace (BOF) and Electric Arc Furnace (EAF) methods. The EAF method is responsible for over 40% of steel produced globally. Since it uses scrap metal as the raw material it is a more competitive and sustainable process
Secondary ion mass spectrometry (SIMS) and laser microprobe mass analysis (LAMMA) have been used to study the surface enrichment of trace elements in dusts emitted from an electric steel making furnace. It is demonstrated that the elements Na, P, S, C1, K, Cr, Mn, Co, Cu, Zn, and Pb are preferentially enriched on the particle surfaces and that ...
Induction furnace is a type of furnace for steelmaking which uses electrical energy for its operation. Induction furnace (IF) steelmaking is one of the two electrical steelmaking processes. The other process for electrical steelmaking uses an electric arc furnace (EAF). Though IFs are being used since a long time, the production of mild steel ...

Because of use of sponge iron the trace elements in the steel made in the IF remains under control. Comparison with Electric Arc Furnace steel making process The comparison of the operating parameters of induction furnace with those of electric arc furnace is given in Table 1.
Note regarding Electric Arc Furnace Dust (EAFD) and galvanising (zinc) The former Irish Steel/Ispat steelworks on Haulbowline Island underwent modernisation in 1972 when a 35 tonne Electric Arc Furnace (EAF) replaced the oil fired open hearth furnace.

The electric arc furnace is the main process unit in scrap-based steelmaking. ... and the oxidation of iron and trace elements with the injected oxygen. The energy lost with the off-gas is mainly chemical ... and many variations of the process with different furnace types, feedstocks, desired steel qualities, and operation strategies have ...
impurity in the ferro-molybdenum added to austenitic stainless steel, with dramatic effects on its hot ductility. Molybdenum oxide, another form of molybdenum addition, can contain copper. (c) From refractories. Some trace elements such as boron can be picked up from, or trans-ferred via the furnace lining. (d) From the recycling of scrap steel.
Steelmaking is the process of producing steel from iron ore and/or scrap.In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel. ...
Electric Arc Furnace Steelmaking By Jeremy A. T. Jones, Nupro Corporation continued Furnace charging Melting Refining De-slagging Tapping Furnace turn-around Top Refining Refining operations in the electric arc furnace have traditionally involved the removal of phosphorus, sulfur, aluminum, silicon, manganese and carbon from the steel.
2.1. Formation of Electric Arc Furnace (EAF) Slag. EAF slag is a non-metallic by-product that consists mainly of silicates and oxides formed during the process of refining the molten steel. As mentioned previously, the feed materials for EAF are mainly steel scrap and pig iron.
Today, steel is a globally sourced commodity, and scrap-based steel production in electric arc furnaces is a popular steelmaking practice. The use of scrap has and will continue to grow, which means the presence of possibly more tramp elements in the future. ... (1900°F), it is advantageous to deliberately add certain trace elements (e.g., Al ...
