Você já se perguntou como os arranha-céus se mantêm altos e fortes? Este artigo explora a maravilha das vigas H padrão americanas, destacando seu design, tipos e aplicações. Você aprenderá como esses gigantes de aço contribuem para a construção moderna com sua força e eficiência. Junte-se a nós para descobrir os segredos por trás dessas maravilhas da engenharia!
A viga H padrão americana está em conformidade com a norma ASTM, com três graus de qualidade principais: A36, A572 e A992.
Por exemplo, os materiais A36 e A572 representam aço estrutural de carbono, enquanto o A992 é um aço de baixa liga.
A viga H padrão americano é um perfil de alto desempenho com uma área de seção transversal otimizada e uma relação resistência/peso mais razoável, que recebeu esse nome devido à sua seção transversal em forma de H.
Devido à sua disposição em ângulo reto em todas as partes, o Viga H apresenta forte resistência à flexão, construção simples, custo-benefício e estrutura leve, o que o torna amplamente aplicável.
O processo envolve a liberação do aço fundido quando sua temperatura e composição atendem às especificações do tipo de aço que está sendo refinado. Durante o vazamento do aço, deve-se tomar cuidado para evitar que a escória entre na panela.
Os aditivos usados para ajustar a temperatura, a composição e a desoxidação do aço fundido são adicionados à panela ou ao fluxo de aço durante a batida, também conhecida como liga de desoxidação.
1) Para aliviar a estresse interno do material
2) Para ajustar a dureza do material (geralmente para aumentar) com uma leve redução na plasticidade
Isso serve para preparar o processamento subsequente. Tem um efeito semelhante ao recozimentoO objetivo é melhorar a eficiência e reduzir os custos.
