Pełny tekst źródłaMobile soil particles can transport pollutants to groundwater. In slag heaps, leached metallic elements contribute to soil water contamination. The aim of this work is to identify the role of slag particles in contaminant transport under unsaturated and saturated conditions. Mineralogical compositions and physicochemical properties of slags are first determined. The analysis show high temperature slag phases and weathering phases. Percolation tests are also carried out in repacked waste columns under infiltration/drying cycles to find out the effects of dry periods on in situ particle mobilization. Preferential flows lead to rapid transport of solute through the repacked column in vadose zone. Leachates are characterized by high pH and high concentrations of calcium, aluminum and silicon, molybdenum, chromium in the fusion slags. Speciation calculations showed that the leachates are saturated in calcium silicate hydrates. Laser size analyzer shows that the slag particles mobilized during the simulated rain events are around 200 µm, which suggests low mobility in the less permeable underlying formations

Pełny tekst źródłaCubatão, situated in the low lying basin behind the porto f Santos on the coast of the state of São Paulo, Brazil, was notorious during the seventies for the environmental chaos produced by the dozens of basic industries and the lack of adequate urban planning, of studies of the environmental impact caused and with negligible resources for the control of pollution, whether of the air, soil or water. Among the factories located in the industrial park of Cubatão, the steelworks is responsible for the largest toxic contribution as also for 60per cent of the fenol and 70per cent of the heavy metals of the overall total of these substances expelled by the factories of the industrial park. A survey of the literature, both national and international, dealing with the associated coke producing plants, was undertaken and presents field research carried out in the course of 13 campaigns giving the results of samples colleted close to the effluents in the company´s port in the Santos estuay. The results of the bioassays used to assess acute toxicity and mutagenicity, Microtox and Ames respectively, were compared with those found in the last researths undertaken by COSIPA in 1986 and 1993 and with those given in the reports of CETESB, the organ responsible for pollution control, in 1992 and 1994. The results which show that the particles presents in the samples were toxic and mutagenic are discussed and lay the foundation for the proposal that the totality of the water used shoud be returned to above the plant in such away as to permit its constant re use, in accordance with the example given by countries of the first world which have learnt to live with the nead for the production of steel

Pełny tekst źródłaThis research presents an overview of the addition steelwork dust of ceramic shingles in order to contribute to the utilization use of such residue. The ceramic industry perspective in the Brazilian State of Piau? is quite promising. Unlike other productive sectors, the ceramic industry uses basically natural raw materials. Its final products are, in short, the result of transforming clay compounds. These raw materials are composed primarily of aluminum oxide, silicon, iron, sodium, magnesium, end calcium, among others. It was verified that steelwork dust is composed primarily of these same oxides, so that its incorporation in to structural ceramics is a very reasonable idea. Both clay and steelwork powder were characterized by AG, XRF, XRD, TGA and DTA. In addition, steelwork dust samples containing (0%, 5%, 10%, 15%, 20% and 25%) were extruded and burned at 800?C, 850?C, 900?C and 950?C. Then t echnological tests of linear shrinkage, water uptake, apparent porosity, apparent density and flexural strengthwere carried at. The results showed the possibility of using steelwork powder in ceramic shingles until 15% significant improvement in physical and mechanical properties. This behavior shows the possibility of burning at temperatures lower than 850?C, thus promoting a product final cost reduction

This dissertational work is to analyze the recent socio-spatial dynamics of the municipality of Açailândia (MA), which was separated from the city of Imperatriz in 1981, and that in a short time of political emancipation, became one of the largest economic centers of the State of Maranhão, highlighting mainly in agriculture, with the highlight the cattle and the steel industry. In the construction of the dissertation, he tried to structure the same, taking into account the theoretical study of the categories territory and territoriality on the perspective of Economic Geography, from there we tried to understand the process of formation of the space of the city of Açailândia, then leaving for an analysis of the economic dynamics of the city, from the 1990s, when large enterprises were already actively working. Wanted also observe and analyze the impact of steel enterprises in the economic of the municipality and at the last moment to turn the attention to the study and analysis of the recent socio-spatial dynamics Açailândia.
O presente trabalho dissertativo tem por objetivo analisar a Dinâmica Socioespacial recente do município de Açailândia (MA), que foi desmembrado da cidade de Imperatriz no ano de 1981, e que em pouco tempo de emancipação politica, tornou-se um dos maiores polos econômicos do Estado do Maranhão, destacando-se principalmente no setor siderúrgico e na agropecuária, tendo como ênfase a bovinocultura. Na construção da dissertação, procurou-se estruturar a mesma, levando em consideração o estudo teórico das categorias território e territorialidade sobre a perspectiva da Geografia Econômica, onde se buscou entender o processo de formação do espaço geográfico do município de Açailândia, partindo então para uma análise da dinâmica socioeconômica do município, a partir da década de 1990, quando os empreendimentos siderúrgicos já estavam funcionando ativamente, e a agropecuária estava em evidencia nessa porção territorial do oeste maranhense. Procura-se ainda nesta pesquisa observar e analisar os impactos dos empreendimentos siderúrgicos na econômica do município, e no último momento a atenção volta-se para o estudo e análises da recente dinâmica socioespacial de Açailândia.

Pełny tekst źródłaThis thesis in Mechanical engineering has been performed at the stainless steel manufacturer Outokumpu Stainless AB, through Uppsala University. At the company's production site some of the produced steel slabs are going through hot grinding in order to get the required surface finish, depending on the customer's demand on quality. There are 8 grinding machines in the grinding station, each of those needs to be provided with new abrasives when the old ones get to worn out. Two robots are installed to execute the abrasives change operation automatically, where each robot maintains 4 grinding machines, two coarse and two fine. This changing process is currently working fully automatically around one percent of the times which constitutes a problem. The thesis is about evaluation and improvement suggestions of this process, where the proportion of succeeded automatically replaced abrasives is in focus. A big part of the work has been based on analysing the existing process in purpose of understanding it fully. After enough knowledge about the process was achieved, investigations about the deficiencies of the process were conducted. Finally improvement suggestions were generated. The main cause of the automation failure is based on the process design and its precision requirements. The environment is tough and the forces are big which affects the process negatively. In addition there are a several components that need to harmonize in order for the abrasives replacement to work properly. Aside from the design of the process other critical factors are dust, component wear, deficient adapted regulation and lacking of alignment routines. Consequences of the failed automatically abrasive replaces are reduced safety, frustration among operators, time loss and economical losses. When the automation stops, the operators have to manually correct the errors alongside the grinding machines in the grinding area. The unstable processes does not necessarily affect the value-adding lead time but forces operators to change the abrasives too early which results in losses in form of non-fully utilized abrasives. Increasing the proportion of automatically fulfilled replaced abrasives is possible but requires much work. Routines are important, especially with alignment of the grinding machines which is a prerequisite for the process to succeed. Replacing of wear damaged components, optimizing the regulation and smaller programming changes are also solutions that contribute to an increasing proportion. To minimize the cost of unutilized abrasives the process is required to perform faster and without interfering with the production. If the company wants to implement a different solution in form of an investment it is important that the solution does not require operators to be inside the grinding area. This is based on safety issues, also the risk of interrupting the production and creating a bottleneck, which can be crucial under more demanding periods. The solution should be a faster, more adaptive system and should not have to rely on alignment and narrow tolerances.

ABSTRACT Within a company individual department always struggle to achieve its own goal. However it is not unusual that the independent efforts from different departments are likely to form conflicts and endanger the success of the company. This research collected two years’ data regarding the production and sales departments of a steelwork factory in Taiwan, and studied the interactions among the departments and factory by System Dynamics (SD). A system dynamics model was successfully constructed to represent the real world situations. Based the real-data-based scenario, the simulated results shows that when each department strives to achieve its own goal, the overall profit decreased. It is shown that the developed SD model can effectively represent the implicit structure of the business flow and help manager understand the hidden problem as well as improve the quality of decision making.

Owing to much public or private economical andengineering activities in Taiwan, there should be many needs on precise alignment and installation for large construction objects. But professional surveyors in Taiwan seem to participate in these project very rarely. The reason may be that people in the field of machinery and civil engineering don't know what surveying can do for their works. Furthermore, surveyors in Taiwan seem to pay less attentions on their needs. Therefore, the real application aspects are less understood.The alignment of TCM (=tandem cold rolling mill) in steelwork is an application case for large mechanisms. The related works are done in a larger area and need high accuracy. From the surveying point of view, there exists something to be considered or improved, e.g. about operational approaches and methods of layout design and alignment as well as successive monitoring, which are controlled or executed by professional mechanist at present.In this thesis, the operational procedures for the TCM-alignment are examined exactly. The principle of network design in engineering survey, data processing methods and quality estimation techniques are used in the network design and analysis for the TCM-alignment. Comparing with surveying methodology adopted in some precise alignment of large mechanical constructions and considering the available instruments at present, some improvement plans are proposed. Applying statistical tests to the deformation analysis of monitoring network, a rigorous way is applicable for the installation and monitoring of TCM.On the other hand, some suggestions are offered for a good cooperation between mechanical engineering and surveying. It is expected that the concerned surveys about the precise alignment of large mechanical equipment will be done more efficiently.
