¿Alguna vez se ha preguntado cómo se mantienen altos y fuertes los rascacielos? Este artículo explora la maravilla de las vigas H estándar americanas, destacando su diseño, tipos y aplicaciones. Descubrirá cómo estos gigantes de acero contribuyen a la construcción moderna con su resistencia y eficacia. Únase a nosotros para descubrir los secretos de estas maravillas de la ingeniería.
La viga H estándar estadounidense cumple la norma ASTM, con tres grados de calidad principales: A36, A572 y A992.
Por ejemplo, los materiales A36 y A572 representan el acero estructural al carbono, mientras que el A992 es un acero de baja aleación.
La viga H estándar americana es un perfil de alto rendimiento con un área de sección transversal optimizada y una relación resistencia-peso más razonable, llamada así por su sección transversal en forma de H.
Debido a su disposición en ángulo recto en todas sus partes, el Viga en H Presenta una gran resistencia a la flexión, una construcción sencilla, rentabilidad y una estructura ligera, lo que la hace ampliamente aplicable.
El proceso consiste en liberar el acero fundido cuando su temperatura y composición cumplen las especificaciones del tipo de acero que se está refinando. Durante la colada del acero, hay que tener cuidado para evitar que entre escoria en la cuchara.
Los aditivos utilizados para ajustar la temperatura, la composición y la desoxidación del acero fundido se añaden a la cuchara o a la corriente de acero durante la colada, lo que también se conoce como aleación de desoxidación.
1) Aliviar la tensión interna del material
2) Para ajustar la dureza del material (generalmente a aumentar) con una ligera reducción de la plasticidad.
De este modo, se prepara para su posterior procesamiento. Tiene un efecto similar a recocidosino que su objetivo es mejorar la eficacia y reducir los costes.
