Efeito da flexão dos cilindros na laminação de encruamento sobre a planicidade de tiras de aço

Abstract: A flexão dos cilindros durante a laminação é um fenômeno que tanto provoca defeitos de planicidade como permite corrigi-los, através da laminação diferenciada ao longo da largura. Este trabalho objetivou avaliar o efeito da flexão estimada dos cilindros na laminação de encruamento sobre a variação da planicidade de tiras laminadas a quente. Isto foi realizado através de experimentos industriais com variação dos parâmetros de força de laminação e de dobramento durante processamento no laminador de encruamento, … Show more

“…The high degree of similarity among the individuals in this environment is related directly to the fragmentation and anthropogenic degradation of the areas populated by the species. Habitat fragmentation may also be a factor determining the genetic similarity among the Ameivula species (SILVA et al, 2008).…”

“…The Caatinga is an exclusively Brazilian biome located within this country's semi-arid zone (Izabel et al, 2011), where relatively high levels of endemism can be found (ABÍLIO et al, 2010). While this biome is still considered to be relatively poorly known, there have been a number of major studies, such as those of Vanzolini et al (1980) and Leal et al (2003Leal et al ( , 2005, although the relative paucity of scientific data does constitute a potential problem for the adequate management of the biome's biodiversity in the face of ongoing anthropogenic impacts (SILVA et al, 2008).…”

“…Adentrando ao meio siderúrgico, de acordo com Silva (2008) [3], a qualidade da planicidade de uma bobina é um defeito claramente percebido e que vem sendo demandada em tolerância cada vez mais restrita pelo mercado. Sendo caracterizadas estas anormalidades principalmente pela presença de ondulações resultantes da acomodação de regiões mais alongados, que costumam se concentrar em regiões do centro ou nas bordas das bobinas.…”

“…The bias, represented by bk, has the effect of increasing or decreasing the net input of the activation function, depending on whether it assumes positive or negative values, respectively. Entering the steel industry, according to Silva (2008), the flatness quality of a coil is a clearly perceived defect that is being demanded in tolerance increasingly restricted by the market. These abnormalities are characterized mainly by the presence of undulations resulting from the accommodation of longer regions, which usually concentrate in regions of the center or the edges of the coils.…”
