Materials The raw materials used in this study were steelmaking slag from an Electric Arc Furnace (EAF), granite cutting residue from an industry on Espírito Santo State - Brazil, and
The Problem with EAF Dust. EAF dust is a by-product of the steel production process, and refers to the dust collected during the melting of steel in an electric arc furnace. In 2006 alone, it was estimated that global production of EAF dust reached a near 7 million tons, a staggering amount, considering the steel industry continues to expand in tandem with growing economies.
Zinc and lead recovery from EAF dusts caustic soda process, Electric Furnace Proceedings, Treatment Options for Carbon Steel Electric Arc Furnace Dust Article Jan 1986
The recovery of alloying additives depends on the type of furnace and individual foundry practices. EAF operations had greater variations in final chemistry performance than induction furnace operations. Laboratory experiments showed that there is a potential for increased alloy recovery and control through argon stirring with a porous plug. Argon

SMS-Siemag Electric Arc Furnace No. 1 & 2. JSPL has taken the technological knowhow and key process equipments from SMS Siemag, Germany for 2 x 100 t EAF, 3 x 100T LF, 1 x 100T RH,and 1 x 100 VD which will produce around 2 MT of liquid steel per annum.
Aug 16, 2011· In 1997, the Waelz process was used to treat over 1 million tonnes of EAF dust, representing 77% of world flue dust reprocessing capacity. K Mager et al. Recovery of Zinc Oxide from Secondary Raw Materials New Developments of the Waelz Process. Published in Fourth International Symposium on Recycling of Metals and Engineered Materials.
Consteel Electric Arc Furnace Process Consteel process is a patented process. It is an innovative energy conservation technology for scrap pre-heating in an electric arc furnace (EAF) developed by 'Intersteel Technology Inc., Charlotte, North Carolina (since 1994 a part of Techint, Tenova S.p.A.).
The most popular process for zinc recovery is the so-called Waelz kiln, located usually outside the steel plant boundaries. These furnaces have been developed in the early twentieth century by zinc producers to enrich low Zn ore (Figure 1.5.21).They have been adopted in the 1950s for EAF dust treatment.
We utilize our unique testing facility, The Innovation Center, to test your material at both batch and pilot scale in order to determine the feasibility of the intended process and simulate commercial process conditions. We then use the data gathered during testing to scale up the process and engineer the equipment needed to carry out the process.
Jun 19, 2017· Electric Arc Furnace Dust Worldwide approximately 6,750,000 tpy of EAFD are produced annually. These dusts contain 1.600.000 tpy of zinc. About 35 Waelz kilns with an average capacity of 75,000tpy are installed worldwide (see partial list below). They process .

Tenova's Energy Recovery Systems for EAF / BOF are the perfect solution for Steam and Hot Water Production. 25-30% of the energy input in industrial furnaces is lost in waste gas and cooling water. The Tenova i Recovery® technology can recover up to 70% of the energy that would be lost.
The SX/EW Process has its roots in analytical chemistry where it is used to separate one metallic ion from another. It was first used as a large-scale process during World War II for the recovery of uranium from its ores. The key to the process is the development of organic extractants that are specific to the metal to be extracted.
Our process optimization system for EAF supports production of a wide range of steel grades, including carbon, stainless and special steels. The application of Steel Expert, a set of metallurgical process models for the optimization of the steelmaking process, leads to fewer steel treatment correction steps, a minimum number of downgraded ...
