Electric Arc Furnace Electric Arc Furnace is a furnace that heats charged material by means of an electric arc. Arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about 400 ton units used for secondary steelmaking. Arc furnaces used in research laboratories and by dentists may have a capacity of only a few dozen grams. Electric arc furnace temperatures can be up to 1,800 degrees Celsius. Arc furnaces differ from induction furnaces in that the charge material is directly exposed to the electric arc, and the current in the furnace terminals passes through the charged material. Electric Arc Furnace can get better steel than induction furnace. The steel from electric arc furnace has less of sulfur and phosphorus. Then it's mechanical property will be good. Electrodes positioned above cold steel scrap and arc is truck increased temperature control.

The microstructure and hardness were examined using optical microscopy and a Rockwell hardness tester. Rotational ball-on-disk sliding wear tests were carried out to investigate the wear behavior of austempered gray cast iron samples and to compare with conventional quenched and tempered gray cast iron samples under equivalent hardness. For the austempered samples, it was found that acicular ferrite and carbon saturated austenite were formed in the matrix. The ferritic platelets became coarse when increasing the austempering temperature or extending the holding time. Hardness decreased due to a decreasing amount of martensite in the matrix. In wear tests, austempered gray cast iron samples showed slightly higher wear resistance than quenched and tempered samples under similar hardness while using the austempering temperatures of 232 ◦C, 260 ◦C, 288 ◦C, and 316 ◦C and distinctly better wear resistance while using the austempering temperatures of 343 ◦C and 371 ◦C.

Society, Materials, and the Environment: the Case of Steel
metals Review Society, Materials, and the Environment: The Case of Steel Jean-Pierre Birat IF Steelman, Moselle, 57280 Semécourt, France; [email protected]; Tel.: +333-8751-1117 Received: 1 February 2020; Accepted: 25 February 2020; Published: 2 March 2020 Abstract: This paper reviews the relationship between the production of steel and the environment as it stands today. It deals with raw material issues (availability, scarcity), energy resources, and generation of by-products, i.e., the circular economy, the anthropogenic iron mine, and the energy transition. The paper also deals with emissions to air (dust, Particulate Matter, heavy metals, Persistant Organics Pollutants), water, and soil, i.e., with toxicity, ecotoxicity, epidemiology, and health issues, but also greenhouse gas emissions, i.e., climate change. The loss of biodiversity is also mentioned. All these topics are analyzed with historical hindsight and the present understanding of their physics and chemistry is discussed, stressing areas where knowledge is still lacking. In the face of all these issues, technological solutions were sought to alleviate their eﬀects: many areas are presently satisfactorily handled (the circular economy—a historical’ practice in the case of steel, energy conservation, air/water/soil emissions) and in line with present environmental regulations; on the other hand, there are important hanging issues, such as the generation of mine tailings (and tailings dam failures), the emissions of greenhouse gases (the steel industry plans to become carbon-neutral by 2050, at least in the EU), and the emission of ﬁne PM, which WHO correlates with premature deaths. Moreover, present regulatory levels of emissions will necessarily become much stricter.

The Parallel Oxidation of Carbon and Chromium
THE PARALLEL OXIDATION OF CARBON AND CHROMIUM IN LIQUID IRON (16oo0 c) by LYALL FRANKLIN BARNHARDT B. Sc. Queen's University (1947) Submitted in partial fullfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY at the Massachusetts Institute of Technology 1965 Signature of Author Department of Metallurgy Signature of Professor in Charge of Research jE Signature of Chairman of - A ii Departmental Committee on Graduate Students VI 38 ABSTRACT THE PARALLEL OXIDATION OF CARBON AND CHROMIUM IN LIQUID IRON (16000c) by LYALL FRANKLIN BARNHARDT Submitted to the Department of Metallurgy in April, 1965, in partial fulfillment of the requirements for the Degree of Doctor of Philosophy. The path followed by carbon and chromium concentrations in liquid iron during oxidation was investigated experimentally by blowing gaseous oxygen on to slag-free iron - chromium - carbon melts at 16004C in an induction furnace. The carbon oxidation reaction occurred at the surface of the melt, with an initial constant rate of decarburization which was dependent on the rate of oxygen input. The mechanism of this reaction is expressed in the chemical equation: C + 1/2 02 (g) = CO (g). During the initial stage, which was characterized by a constant rate of decarburization, carbon oxidized preferentially with no loss of chromium. Beyond this stage, the rate of carbon loss declined rapidly and the oxidation of iron and chromium occurred. The entry of argon into the furnace atmosphere, during the oxygen blow, lowered the partial pressure of carbon monoxide at the metal surface. This allowed the carbon concentration of the melt to drop far below the equilibrium iii carbon content for one atmosphere pressure of carbon monoxide.

Effect of Melting Process and Aluminium Content on the Microstructure and Mechanical Properties of Fe–Al Alloys
ISIJ International, Vol. 50 (2010), No. 10, pp. 1483–1487 Effect of Melting Process and Aluminium Content on the Microstructure and Mechanical Properties of Fe–Al Alloys Shivkumar KHAPLE, R. G. BALIGIDAD, M. SANKAR and V. V. Satya PRASAD Defence Metallurgical Research Laboratory, Kanchanbagh, Hyderabad, 500058 India. E-mail: [email protected] (Received on January 4, 2010; accepted on July 1, 2010) This paper presents the effect of air induction melting with ﬂux cover (AIMFC) versus vacuum induction melting (VIM) on the recovery of alloying element, reduction of impurities, workability and mechanical prop- erties of Fe–(7–16mass%)Al alloys. Three Fe–Al alloy ingots containing 7, 9 and 16 mass% Al were prepared by both AIMFC and VIM. All these ingots were hot-forged and hot-rolled at 1 373 K and were further charac- terized with respect to chemical composition, microstructure and mechanical properties. The recovery of aluminium as well as reduction of oxygen during both AIMFC and VIM is excellent. AIMFC ingots exhibit low level of sulphur and high concentration of hydrogen as compared to VIM ingots. VIM ingots of all the three alloys were successfully hot worked. However, AIMFC ingots of only those Fe–Al alloys containing lower concentration of aluminium could be hot worked. The tensile properties of hot-rolled Fe–7mass%Al alloy produced by AIMFC and VIM are comparable. The present study clearly demonstrates that it is feasible to produce sound ingots of low carbon Fe–7mass%Al alloy by AIMFC process with properties comparable to the alloy produced by VIM. KEY WORDS: air inducting melting with ﬂux cover; vacuum induction melting; Fe–Al alloy; microstructure; mechanical properties.

Primary Mill Fabrication
Metals Fabrication—Understanding the Basics Copyright © 2013 ASM International® F.C. Campbell, editor All rights reserved www.asminternational.org CHAPTER 1 Primary Mill Fabrication A GENERAL DIAGRAM for the production of steel from raw materials to finished mill products is shown in Fig. 1. Steel production starts with the reduction of ore in a blast furnace into pig iron. Because pig iron is rather impure and contains carbon in the range of 3 to 4.5 wt%, it must be further refined in either a basic oxygen or an electric arc furnace to produce steel that usually has a carbon content of less than 1 wt%. After the pig iron has been reduced to steel, it is cast into ingots or continuously cast into slabs. Cast steels are then hot worked to improve homogeneity, refine the as-cast microstructure, and fabricate desired product shapes. After initial hot rolling operations, semifinished products are worked by hot rolling, cold rolling, forging, extruding, or drawing. Some steels are used in the hot rolled condition, while others are heat treated to obtain specific properties. However, the great majority of plain carbon steel prod- ucts are low-carbon (<0.30 wt% C) steels that are used in the annealed condition. Medium-carbon (0.30 to 0.60 wt% C) and high-carbon (0.60 to 1.00 wt% C) steels are often quenched and tempered to provide higher strengths and hardness. Ironmaking The first step in making steel from iron ore is to make iron by chemically reducing the ore (iron oxide) with carbon, in the form of coke, according to the general equation: Fe2O3 + 3CO Æ 2Fe + 3CO2 (Eq 1) The ironmaking reaction takes place in a blast furnace, shown schemati- cally in Fig.
