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. Use of ornamental rock residues for mould flux development
Abstract Ornamental rock production, such as marble and granite plates, have great importance in the southeastern region of Brazil. Its residues are composed of some compounds used in continuous casting as mould fluxes. Therefore, the aim of this article was to study these residues to formulate mould fluxes. First, the raw materials were chemically character

5. Effect of casting mode and thermal treatments on the electrical conductivity of the AA4006 aluminum alloy
Abstract Initially studied was the effect of the casting mode on the electrical conductivity of AA4006 aluminum alloy sheets produced by both Twin Roll Casting (TRC) and by the semi-continuous Direct Chill (DC) industrial processes, when compared to sheets with commercial purity (AA1050) and high purity aluminum (AA1199). Then, the effects of heat treatments

7. On the Natural Convection in the Columnar to Equiaxed Transition in Directionally Solidified Aluminum-based Binary and Multicomponent Alloys
In order to investigate the effect of natural convection in columnar to equiaxed transition (CET), Al-3.0wt.%Cu and Al-3.0wt.%Cu-5.5wt.%Si alloys ingots were obtained during the transient horizontal directional solidification (THDS). Aiming to analyze the effect of superheat in the formation of the macrostructure in ternary Al-Cu-Si alloy, the experiments we

8. Numerical Simulation of Zr-based Bulk Metallic Glass During Continuous Casting Solidification Process
A numerical simulation method was used to analyze the solidification process of Zr-based bulk metallic glass (BMG) during the horizontal continuous casting (HCC) process. The large-scale general-purpose finite element analysis software ANSYS was adopted to develop a temperature field model. The variation of temperature field in the specific area at different

9. 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

10. Mechanical, thermal, and barrier properties of methylcellulose/cellulose nanocrystals nanocomposites
In this work, the effects of incorporating cellulose nanocrystals from soy hulls (WSH30) on the mechanical, thermal, and barrier properties of methylcellulose (MC) nanocomposites were evaluated. MC/WSH30 nanocomposite films with different filler levels (2, 4, 6, 8, and 10%) were prepared by casting. Compared to neat MC film, improvements in the mechanical an

11. The effect of adding boron in solidification microstructure of dilute iron-carbon alloy as assessed by phase-field modeling
Alloying element like boron, even in small addition, is well known to improve hardenability of steels. Its application can improve mechanical properties of steels and reduce alloying costs. Despite these benefits is not easy to cast boron steels, mainly in dynamical solidification process like continuous casting, due to their crack susceptibility1,2. The str

12. 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
