1. Análise da geração de energia elétrica por meio da utilização de conversores do tipo TEG em lingotamento contínuo de aços
RESUMO A fabricação do aço é um processo que requer enormes quantidades de recursos, como por exemplo combustíveis, minério de ferro, carvão, entre outros. Com a crescente preocupação com o meio ambiente, seja pelas cargas ambientais ou pelo aquecimento global, cresce também a necessidade do desenvolvimento de novas tecnologias que possibilitem um

2. Simulación matemática para la optimización del patrón de flujo entregado por una buza para el molde de colada continua de planchón delgado
ABSTRACT Understanding the behavior of the oscillations of the jets into the mold of thin slab funnel is essential to ensure a constant supply of liquid steel, improve control of the flow patterns and consequently increase plant productivity and the final product quality. To achieve this, we conducted a study of the effect of the internal design of the nozzl

3. The influence of tundish heating and purging on inclusion formation
Steel with high cleanliness requirements require an accurate control of the non-metallic inclusions, such as its quantity, morphology, chemical composition and size distribution. The continuous casting tundish has a fundamental role in steel cleanliness, avoiding its reoxidation by air and ladle slag that retain inclusions, as well as aiding the removal of t

4. Desenvolvimento de software de simulação da solidificação de aços no processo de lingotamento contínuo de tarugos / Development of simulation software for the continuous casting process of steel billets
The development and application of simulation software for the continuous casting process is proposed in this work. The heat transfer and solidification models were validated with experimental results of temperature measurements in an industrial plant as well as with steel billets samples. Thermocouples embedded in the mold walls were used to measure tempera

5. Numerical model of electromagnetic stirring for continuos casting billets
Thispaperintroducesanumericalmodelofanelectromagnetic rotary stirrer based on the finite-element model.Such stirrers are used to improve the quality of continuously cast steel, particularly billets and blooms. The method determines the magnetic flux density profile and compares it to experimental measurements. In addition, it calculates the Lorentz force fie

6. Effect of thermo-mechanical parameters on microstructure and mechanical properties of microalloyed steels
In this work the effects of controlled rolling parameters and adding of Niobium have been studied. In this order two steel grades with and without Niobium are planed and after steelmaking and continuous casting, rolling process are done. Then, laboratory investigations such as microstructure, mechanical properties and grain size analysis were performed Tensi

7. Efeitos térmicos e fluido-dinâmicos devidos a um agitador eletromagnético para tarugos
O uso de agitadores eletromagnéticos (EMS) durante o lingotamento contínuo tornou-se imprescindível para a obtenção de aços de melhor qualidade. Embora os efeitos da agitação durante o processo de solidificação sejam pouco conhecidos do ponto de vista teórico, pode-se estudar esses efeitos sobre o perfil de escoamento antes do aço solidificar. Es

8. Estudo sobre o pick-up de nitrogênio após a etapa de refino primário do aço
With the growing need of high quality steel there is a great demand for the development and production of steels with ever stringent chemical composition restrictions. For instance the presence of carbon and nitrogen in Interstitial Free steels for automobile industry. These restrictions are defined by the final application to which the product is destined.

11. Influência do ângulo de posição sobre o fresamento frontal de níquel puro com insertos de metal duro
Nickel is considered as a dificult-to-cut material, due to rapidly work hardening when machined. Because it shows high strength at high temperatures it is widely used as high temperature alloys in aerospacial components and more specifically is applied in the continuous casting industry, in molds which consist of a copper sheet with pure nickel electroplated
