Tenova, a Techint Group company specialized in solutions for the metals and mining industries, was recently awarded three iRecovery (intelligent waste heat recovery systems) by Tangshan Zhengfeng Iron Steel Co., LTD, in Hebei Province, China.
Understanding Electric Arc Furnace Steel Making Operations Electric arc furnace (EAF) steel making technology is more than hundred years old. Though De Laval had patented an electric furnace for the melting and refining of iron in 1892 and Heroult had demonstrated electric arc melting of ferro alloys between 1888 and 1892, the first industrial ...
Many innovations grow from the desire to achieve something or to complete a task that is needed to accomplish a broader goal. For example, Xerox Corporation hired a pair of researchers as "innovation managers" to hunt for inventions and products from startups .

In the semiintegrated process, the main ones are the slag of electric steelmaking, EAF dust and mill scale continuous casting and rolling. Electric arc furnace (EAF) dust. The EAF dust is generated during melting of scrap in electric arc furnace and collected by bag filters or electrostatic precipitators.
Steel slag is a byproduct of the steelmaking and steel refining processes. This paper provides an overview of the different types of steel slag that are generated from basicoxygenfurnace (BOF) steelmaking, electricarcfurnace (EAF) steelmaking, and ladlefurnace steel refining processes. The mineralogical and morphological properties of BOF and electricarcfurnaceladle [EAF(L)] slag ...
The Primus process is well adapted for processing dust, which contains more than 5 % of zinc and is typically generated by EAF minimills. When fed with EAF dust, Primus produces hot metal of a quality similar to the one produced by a blast furnace, zinc oxide concentrate (more than 55 % Zn) and an inert slag which can be used for road construction.
Jul 10, 2017· Leaching in Metallurgy and Metal Recovery. ... The simple act of steeping tea is, in fact, very similar to the process of leaching in metal recovery. Although you may be skeptical of my comparison, I assure you that I can explain what I mean. Leaching, by definition, is the process of extracting a substance from a solid material, after it has ...
MERIM® Maximized emission reduction and energy recovery. Primetals Technologies has developed advanced dry top gas cleaning technology for blast furnaces, COREX and FINEX, with considerable benefits for the environment and customers compared to the conventional wet top gas cleaning system.
Electricarc furnace dust (EAFD) is one of the several process residues generated in mini mills during steel production. The presence of valuable zinc in EAF dust and the rising costs for waste disposal are the motivating factors for EAFD recycling or its incorporation into other materials.
An ECS heat recovery system, iRecovery, was installed by the end of 2015 at the ORI Martin steel plant of Brescia in Italy. This system, installed downstream of the EAF Consteel furnace, will have the task to recover part of the energy contained in the fumes generated during the scrap melting and superheating process in the electrical furnace.
PDF | This chapter deals with electric furnace steelmaking, a tool for the massive production of steels, which is responsible for 30% of the current worldwide production. The EAF is a field for ...

Waelz Oxide ("WOX") WOX (sometimes called crude zinc oxide or CZO) is produced from the recycling of EAF dust in our Waelz Kilns, which is a High Temperature Metals Recovery process designated as Best Available Demonstrated Technology by the EPA for managing EAF dust, a listed hazardous waste under EPA regulations.
well as the process flow diagram are shown in Fig. 3. Waste Heat Recovery Systems for EAF — Even if the waste heat potential is high enough, there are several challenges for designing a waste heat recovery plant. Due to the dynamic operation of the EAF process, as well as idle periods of the furnace, the offgas param
DRAFT – PREDECISIONAL – DRAFT 6 124 Figure 3: Waste heat losses and work potential from selected process exhaust gases [3] 125 126 NOTE: Steam boilers are divided into conventional fuels (CF) and byproduct fuels (BF). It is important to note that 127 while steam boilers have higher waste heat losses; this is due to the large number of industrial boilers (about 43,000
EAFD is a hazardous solid waste and environmental pollutant which is generated in the collection of particulate material during steelmaking process via electric arc furnace. It is a fine powder passed through cooling pipes and then filled and kept in specially designed bag filters.
Zinc and lead usually occur together in a variety of mineral zinc ores and some solid wastes such as steel mill electric arc furnace (EAF) dust [1]. During the steelmaking process, the EAF can reach temperatures of 1600°C or higher.
