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 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.
the recovery of zinc and cadmium from the purified solutions were briefly studied. Finally, a conceptual flowsheet of the proposed integrated hydrometallurgical method for the treatment of EAF dust was established and is given. 2. Experimental 2. 1. Material The electric arc furnace dust (EAFD) sample used was received from the dust collecting

The targeted sectors are currently under extreme financial and environmental pressure both on raw material inputs and waste disposal and have been identified as important application areas for this eco-innovative material recovery (metal valorisation) process, in energy efficiency and economic terms
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.

furnace/basic oxygen furnace (BF/BOF) and electric arc furnace (EAF) production. BF/BOF production uses iron ore to produce steel. The reduction of iron ore to iron in a BF is the most energy-intensive process within the steel industry. EAF production re-melts scrap to produce steel. BF/BOF production is more energy intensive and emits more CO. 2
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 .
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.
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
Aug 27, 2019· Electric Arc Furnace Steelmaking Just after the turn of the century, another development occurred that would have a strong influence on the evolution of steel production. Paul Heroult's electric arc furnace (EAF) was designed to pass an electric current through charged material, resulting in exothermic oxidation and temperatures up to 3272 ° F ...
EAF – Technology and process In the last 100 years,the EAF technology has evolved to meet the demands of higher productivity, improved quality of product and flexibility of metallic inputs. The product mix of modern EAF encompasses all steel grades with an optimised charge mix.
