In the semi-integrated process, the main ones are the slag of electric steelmaking, EAF dust and mill scale continuous casting and rolling. 1.2. 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.
• Paradigm Innovation: Paradigm-based innovations relate to the mental models which shape what an organization or business is about. • EAF, with its differences from traditional manufacturing methods, was exactly an example of this types of innovation in the end of 1800's.
Electric-arc 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.
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.

DRAFT – PRE-DECISIONAL – 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
In today's world, major steel production companies manufacture steel utilizing basic oxygen methods—a process that basically involves oxygen being blown into large-sized vessels that carry scrapped steels and molten iron. Another growing method of mass steel production is through the use of electric arc furnaces or EAF.
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.

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 ...
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 basic-oxygen-furnace (BOF) steelmaking, electric-arc-furnace (EAF) steelmaking, and ladle-furnace steel refining processes. The mineralogical and morphological properties of BOF and electric-arc-furnace-ladle [EAF(L)] slag ...
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.
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 U.S. EPA for managing EAF dust, a listed hazardous waste under EPA regulations.

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.
