I. Introdução ao feixe H padrão americano da série W
A viga H padrão americano está em conformidade com o padrão ASTM, com três graus principais de qualidade: A36, A572 e A992.
Por exemplo, os materiais A36 e A572 representam aço estrutural de carbono, enquanto 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, nomeada devido à sua seção transversal em forma de H.
Devido à sua disposição em ângulo reto em todas as peças, a viga H apresenta forte resistência à flexão, construção simples, economia e estrutura leve, tornando-a amplamente aplicável.
II. Composição Química da Viga H Padrão Americano Série W
- C: 0,27~0,35;
- Si: 0,93~1,20;
- Ni: ≤0,029;
- Cu: ≤0,025;
- Mn: 0,80~1,10;
- S: ≤0,025;
- P: ≤0,026;
- Cr: 0,75~1,20;
III. Desempenho de desoxidação e liga de aço com viga H padrão americano da série W
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 rosqueamento do aço, deve-se tomar cuidado para evitar que a escória entre na panela.
Os aditivos usados para ajustar a temperatura, composição e desoxidação do aço fundido são adicionados à panela ou ao fluxo de aço durante o rosqueamento, também conhecido como liga de desoxidação.
4. Objetivo de normalizar o feixe H do padrão americano:
1) Para aliviar o estresse interno do material
2) Para ajustar a dureza do material (geralmente para aumentar) com uma ligeira redução na plasticidade
Isto é para se preparar para o processamento subsequente. Tem efeito semelhante ao recozimento, mas visa melhorar a eficiência e reduzir custos.
