life cycle inventory processes of the arcelormittal poland amp s a in krakow poland basic oxygen furnace steel production
International Journal of Life Cycle Assessment, 2012Co-Authors: Boguslaw BiedaAbstract:Purpose The goal of this paper is to describe the life cycle inventory (LCI) approach to steel produced by ArcelorMittal’s Basic Oxygen Furnace (AMBOF) in Krakow, Poland. The present LCI is representative for the reference year 2005 by application of PN-EN ISO 14040:2009 (PN-EN ISO 2009). The system boundaries were labeled as gate-to-gate (covering a full chain process of steel production). The background input and output data from the basic oxygen furnace (BOF) steelmaking process has been inventoried as follows: pig Iron, Scrap, slag forming materials (CaO), ferroalloys, Al, carbon and graphite carburizer (material for carburization of steel), isolating powder, consumption of energy and fuels including natural gas, blast furnace gas and coke oven gas, electric energy, steam, air, oxygen, industrial water and heat, emission of air pollutants, waste, internal transport and land use.

Life cycle inventory processes of the ArcelorMittal Poland (AMP) S.A. in Kraków, Poland\-basic oxygen furnace steel production
International Journal of Life Cycle Assessment, 2012Co-Authors: Boguslaw BiedaAbstract:The goal of this paper is to describe the life cycle inventory (LCI)\napproach to steel produced by ArcelorMittal's Basic Oxygen Furnace\n(AMBOF) in Krakw, Poland. The present LCI is representative for the\nreference year 2005 by application of PN-EN ISO 14040:2009 (PN-EN ISO\n2009). The system boundaries were labeled as gate-to-gate (covering a\nfull chain process of steel production). The background input and output\ndata from the basic oxygen furnace (BOF) steelmaking process has been\ninventoried as follows: pig Iron, Scrap, slag forming materials (CaO),\nferroalloys, Al, carbon and graphite carburizer (material for\ncarburization of steel), isolating powder, consumption of energy and\nfuels including natural gas, blast furnace gas and coke oven gas,\nelectric energy, steam, air, oxygen, industrial water and heat, emission\nof air pollutants, waste, internal transport and land use.\nLCI steelmaking process was developed mainly on the basis of the\nfollowing sources: site-specific measured or calculated data, study\ncarried out by the AGH University of Science and Technology in Krakw,\nAMP EnvIronmental Impact Report, study carried out by the Faculty of\nMining Surveying and EnvIronmental Engineering of the AGH University of\nScience and Technology in Krakw, literature information and expert\nconsultations. The functional unit (FU) is represented by 1,677,987 Mg\nof steel, produced by BOF steelmaking process. Time coverage is 2005.\nOperating parameters as well as air emissions associated with the BOF\nsteelmaking process were presented. The production data (steel) was\ngiven. The emissions of SO2, NO2, CO, CH4, CO2, dust, heavy metals (Cr,\nCd, Cu, Pb, Ni and Mn) and waste (slag and gas cleaning sludge) are the\nmost important outcomes of the steel process.\nWith regard to 1,677,987 Mg of steel produced by AMBOF, the consumption\nof natural gas, blast furnace gas and coke oven gas amounted to\n10,671,997, 755,094 and 13,222,537.6 m(3)/year, respectively. Electric\nenergy, steam, air, oxygen and heat input amounts were in the order of\n45,003,611.3 kWh, 21,646.03 Mg, 107,592,526 m(3), 90,611,298 m(3) and\n16,779.87 GJ, respectively. Direct emissions in air of SO2, NO2, dust,\nCr, Cd, Cu, Pb, Ni, Mn, CO and CH4 from three converters (Nos. 1-3) were\non the order of 28.966, 71.331, 752.05, 0.025, 0.024, 0.0216, 0.0156,\n0.0163, 1.5694, 540.449 and 0.364 Mg, respectively. Total CO2 emission\nwas 138,374 Mg. The amounts of slag and gas cleaning sludge were\n276,709.64 and 16,749 Mg, respectively.\nThe LCI study resulted in the development of a database with a vast\ninventory of data regarding steelmaking process in AMBOF referring to\nthe year 2005. The output of the AMBOF LCI study is a set of\ngate-to-gate LCI data for steel production in BOF technology. This is\nthe first tentative study to express steel production in Poland in terms\nof LCA/LCI in the steelmaking industry. The FU chosen for the present\nstudy is 1,677,987 Mg of steel produced in a classical BOF. The quality\nof data input in this LCI study is very good. The rules were used in\naccordance with ISO Standard for LCA. The methodological approach and\nboundaries that were made are transparent and fully documented. The\npurpose of this study is to help AMP authorities solve envIronmental and\ntechnical aspects as well as to train steel industry people in the field\nof life cycle assessment. In addition, this study can be extended to\nother processes involved in steelmaking route (via sintering plant/hot\nrolling plant). Moreover, these results move the LCI study on the\nsteelmaking process one step forward.\nThe LCI offers envIronmental information consisting of the list of\nenvIronmental loads. The impact assessment phase aims to present more\nunderstandable results from the inventory analysis, and life cycle\nimpact assessment (LCIA) will be the direction for future research.\nAnother issue to discuss is the integration of LCA with risk assessment\nfor industrial processes.

the preparation and property research of the stainless steel Iron Scrap clad plate
Journal of Materials Processing Technology, 2014Co-Authors: Shaokun Zhang, Hong Xiao, Lichao GuAbstract:Abstract As an attempt to recycle Iron Scraps, a new method is proposed to produce stainless steel clad plate by hot rolling. Iron Scraps (Q195) were cold pressed into stainless steel pipe (304), and were subsequently hot rolled to produce composite clad plates at 1250 °C. Experiments showed that the Iron Scraps could be compressed into solid steel and joined well with the outer stainless steel surface using the proposed method. The shear strength of the bimetallic interface formed is about 273 MPa after seven pass rolling. The clad plates produced show good bending ductility. Element diffusion occurred at the interface during the hot rolling processes. The peak hardness appears in the vicinity of the interface due to the severe plastic deformation under high temperature and pressure during the rolling processes.
