Item Estudo da influência da temperatura na alteração do revestimento permanente do fundo de uma panela de aço em uma aciaria elétrica(2022-01-09) Diniz, Emilly Vithória Oliveira Rocha; Diniz, Verônica Cristhina de Souza; http://lattes.cnpq.br/9239037374332331; http://lattes.cnpq.br/4526803179109939Steel is an iron-carbon alloy, which can be used in the most diverse sectors of the economy due to its low manufacturing cost and its chemical and mechanical properties. Refractory materials are part of the manufacture of steel through the composition of the internal lining in the equipment used in the manufacture of the same. Different types of refractory materials can be applied in these equipments, namely: dolomitic, magnesium, aluminous. In the present work, the modification of the thickness of the permanent coating of the steel ladle will be discussed in order to increase the weight of cast steel, performing the necessary measurements and comparisons to guarantee operational safety, obtaining results within the established limits, enabling the change.Item Análise da resistência a corrosão do aço API 5L X70 revestido com inconel 625 por soldagem plasma pó e por arco submerso(2021-12-09) Ferreira, Beatriz Cândida de Farias; Santos, Aureliano Xavier dos; http://lattes.cnpq.br/0810494477757052; http://lattes.cnpq.br/8533374114394812Annually, the oil industry invests large amounts in pipeline maintenance, mainly in anti- corrosion measures. Thus, solutions are sought that combine low cost, reproducibility and consistent properties. One of them is the use of materials that have high mechanical and anti- corrosive properties in the form of coatings that can be deposited by welding. This study aimed to evaluate the effects of different welding parameters on the corrosion resistance of inconel 625 alloy coatings deposited by API 5L X70 steel by the PTA welding process , evaluate samples with higher and lower dilution and use the parameters of these experiments to perform SAW submerged arc welding coating in order to compare the processes. The parameters were optimized through factorial experimental design and the results analyzed by the Response Surface Methodology (MSR). The samples were mainly evaluated by dilution (D), iron content (Fe) and resistance to corrosion by linear potentiodynamic polarization (PPL).
