Texte intégralThe aims of the present PhD thesis are to determine a model that is both sufficiently accurate and numerically exploitable to propose optimal placement of sensors and actuators for active vibration control in a galvanizing line. A continuous hot-dip galvanizing process consists in covering a metal (here: a steel band) by a protective layer of zinc which avoids the corrosion due to the air. The thickness of this layer must be constant to guarantee the mechanical properties and surface condition of the product. In a galvanizing line, the moving steel strip is heated and then immersed in a liquid zinc bath before being wiped out by nozzles projecting air. The air flow, as well as the rotation of the driving rolls, among other things, creates vibrations affecting the wiping process and thus the regularity of the zinc deposit. Active control is therefore necessary, for example by means of electromagnets placed on either side of the moving steel strip. In a first step, a behavioral model of the steel strip taking into account the presence and propagation of vibrations was obtained by spatial discretization of a partial differential equation. This state space model was validated in simulation and experimentally on a pilot galvanizing line of ArcelorMittal Research in Maizières-lès-Metz. Once this model is established, the objective of the study is to find the optimal placement of sensors, to measure the vibrations of the strip as efficiently as possible, but also of actuators to minimize the amplitude of these vibrations by an appropriate control law. These problems of optimal placement are at the heart of the issues of active vibration control and are found in many fields of application. An optimal placement method based on Gramian maximization has been proposed in order to reduce the impact of disturbances on the system. Different control strategies have been considered such as (i) observed state feedback based on Kalman filter and LQ regulator; and (ii) extended observed state feedback to improve the results by also taking into account the disturbance estimation provided by a PI (proportional-integral) observer. Simulation and experimental results illustrate the thesis contributions

Texte intégralThe present work describe the experiments carried out based on the wire drawing process analysis and later annealing on lead furnace on a galvanizing line. Using D.O.E methodology, the aim is to understand the occurrence of lead entrainment originating from the annealed wires in order to decrease this problem. Wire samples were collected from wire drawing machines and galvanizing line and submitted to surface roughness analysis and its implications on lead drag out based on wire speed, wire diameter, lead bath temperature, thermal capacity of the lead kettle, wire surface condition, wire roughness and wire superficial cleanliness. Proposals to decrease lead drag out were made in order to increase wire drawing machines and galvanizing line performance.

Texte intégralThe batch galvanizing process (BGP) can lead to surface contamination of hot-dip galvanized steel (HDGS) with chloride residues. If these residues are not effectively eliminated, they can influence negatively on the performance of duplex systems (galvanizing plus painting). It is known that the chromate quenching is widely used in the BGP, however the effect of this post-treatment on the performance of duplex systems is not well established yet. In this sense, this work aimed: I to verify the contamination degree of HDGS with chloride salt due to the BGP itself; II to verify the effects of the chloride salt contamination and chromate quenching on the performance of paints applied on HDGS; and III to determine the suitable surface preparation for painting in order for obtaining a good paint performance applied on HDGS. The adopted methodology to achieve goal I involved the galvanizing of steel plates in different service renderings with BGP, in different conditions. These HDGS plates were submitted to the qualitative energy dispersive microanalyses (EDS) in scanning electron microscopy (SEM) and to the determination of superficial chloride contents by the boiling water extraction method. From the obtained results, the conditions in the BGP that potentially lead to greater surface contamination of HDGS with chloride salt were determined. Thus, to achieve goals II and III, steel plates were galvanized under the maximum chloride salt contamination condition and part of them were submitted to chromate quenching. After that, a great part of these HDGS plates (chromated or non chromated quenching) was submitted to the surface preparations for painting through organic solvent cleaning, high pressure hydroblasting, sweep blasting and handled scrub cleaning with an abrasive sponge and hot distilled water. Finally, the HDGS plates, including those not submitted to the surface preparations for painting, were painted with one coat of primer plus one coat of finishing paint. The HDGS painted plates were submitted to accelerated (distilled water immersion and humidity chamber exposure) and non accelerated (atmospheric exposure) corrosion tests and their performance were verified by means of traditional tests (degree of blistering and paint adhesion) and electrochemical measurements (open circuit potential, polarization curve and electrochemical impedance spectroscopy E.I.S.). Before painting, some HDGS plates were submitted to tests for physical (microstructural and morphological analyses in MEV and surface roughness), chemical (EDS, X-ray diffraction and superficial chloride contents by the boiling water extraction method) and electrochemical characterization. The obtained results allowed verifying that the additional application of solid ammonium chloride salt during the BGP tends to increase the degree of superficial chloride contamination of the HDGS and, the water and/or chromate quenching also contribute for this contamination. In general, the chromated HDGS presented worst performances. The high pressure hydroblasting and the handled scrub cleaning with an abrasive sponge and hot distilled water were the surface preparations for painting that provided the best performances of paint systems.

Texte intégralAs ferramentas da qualidade, mais especificamente as cartas de controle, são importantes recursos estatísticos para se conhecer e monitorar processos produtivos, sendo que seu objetivo é encontrar as causas comuns e assinaláveis de um processo para, com seu monitoramento, aumentar sua estabilidade e, a partir daí, considerar se o processo está sob controle. A dinâmica das atividades industriais hoje existentes fez surgir novas necessidades para um bom monitoramento, e, nesse sentido, novas ferramentas de controle foram desenvolvidas, capazes de entender as novas relações causais entre as variáveis. A pesquisa apresenta o uso de três metodologias de modelagem para tratar dados autocorrelacionados possibilitando o monitoramento de um processo produtivo de eletrogalvanização. Inicialmente foi realizada uma análise descritiva para a verificação de pressupostos de normalidade e independência e após foram ajustados os modelos ARIMA de Box e Jenkis, modelos ARMAX e modelos de regressão linear múltipla, MRLM, para posterior construção das cartas de controle dos resíduos. Além do conhecimento acadêmico proporcionado, apresenta mais de uma aplicação das cartas de controle ao ambiente industrial, e também colabora com a empresa onde a pesquisa foi desenvolvida mostrando qual das metodologias é mais efetiva no controle da produção. O melhor resultado de monitoramento obtido com o trabalho estatístico nessas três metodologias quando confrontado com o método de controle convencional, ou seja, sem tratar a autocorrelação foi utilizando a modelo ARIMA e posterior aplicação dos gráficos de controle de resíduos oriundos desta modelagem. A decisão da metodologia de modelagem mais eficaz para a eletrogalvanização foi definida pelo número de pontos encontrados fora dos limites convencionais estabelecidos. A que melhor captou as flutuações do processo foi a obtida com os resíduos do ARIMA.

Texte intégralThe automobile industry, when seeking to increase warranty against corrosions, employs galvanized IF (intersticial free) steels to the body shell, since these meet the superficial, compliance, weldability and other quality criteria. In this context, the corrosion resistance of an IF steel with galvanic coating (GI) and different weights (85 g/m2 (Z85), 100 g/m2 (Z100), 120 g/m2 (Z120), 144 g/m2 (Z144) and 180 g/m2 (Z180), phosphated and with cataphoresis, were evaluated through an accelerated cyclical corrosion experiment. The result of this experiment showed that even with the variation of the galvanic coating (GI) the result of the corrosion resistance was the same, leading to the hypothesis that the intermetallic layer which is present in all samples, regardless of the weight, must influence corrosion resistance. Thus, supplementary experiments were done to comprehend the effect of the zinc layer and the intermetallic layer in corrosion resistance. The characterization of the layers formed in the GI galvanizing process was done in the Z100 (100g/m²) sample. This sample was chosen because it is the most used in the automobile industry and it did not suffer any previous treatment since the objective was to analyze only the layers of galvanized GI. The experiments done were in the microstructure (XRD, MEV and EDS) and electrochemical experiment (potenciodinamic polarization). We concluded that the intermetallic layer is formed by phases Fe2Al5 and FeAl3, with predominance of phase Fe2Al5. It was verified through the electrochemical dissolution experiment that the intermetallic corrosion resistance is at minimum 7 times greater than of the zinc, further on this result, the potentiodynamic polarization experiment shows that the passive intermetallic layer slows the oxidation velocity, which means, the galvanic coating (GI) corrosion resistance is increased.

Galvanized parts as the underlying corrosion treatment have better anti-corrosion effect. Also, the anti-corrosion ability can be enhanced if the film formation process is subjected to electrical galvanized surface. Film formation process of the present technology is divided into hexavalent and trivalent chromium, hexavalent chromium is toxic and will cause harm to humans and the environment, and trivalent chromium is not only non-toxic and harmless to human body, is also easier to handle wastewater, not a burden on the environment. So trivalent chromium chemical conversion coating film is the mainstream of future development. Trivalent chromium chemical conversion coating film can be classified into blue zinc, multicolored, and black zinc coating, the present study was to investigate the trivalent chromium chemical conversion coating film in a colorful coating. The study includes the temperature of the reaction process, P/H value, and the corrosive nature of the completion of the plating color. Then through the key parameters in the analysis of experimental data to optimize the process to achieve low cost, good quality, high efficiency, and high yield results. In this study, the experimental results show that the process of trivalent chromium galvanizing in the P/H value of 2.2, the temperature value of 40 ℃ and the concentration of 8 % in plating environment, have superior quality that the others. In the future, trivalent chromium chemical conversion coating film will gradually replace hexavalent chromium. Because of its non-toxic, easy to handle wastewater, and meet the regulations and requirements of green production line with modern environmental.
