Vi siete mai chiesti come fanno i grattacieli ad essere alti e forti? Questo articolo esplora la meraviglia delle travi H standard americane, evidenziandone il design, i tipi e le applicazioni. Scoprirete come questi giganti d'acciaio contribuiscono all'edilizia moderna con la loro forza ed efficienza. Scoprite con noi i segreti di queste meraviglie dell'ingegneria!
La trave H standard americana è conforme allo standard ASTM, con tre principali gradi di qualità: A36, A572 e A992.
Ad esempio, i materiali A36 e A572 rappresentano acciai strutturali al carbonio, mentre l'A992 è un acciaio basso legato.
La trave H standard americana è un profilo ad alte prestazioni con una sezione trasversale ottimizzata e un rapporto resistenza/peso più ragionevole, che prende il nome dalla sua sezione trasversale ad H.
Grazie alla sua disposizione ad angolo retto in tutte le parti, il Trave ad H La forte resistenza alla flessione, la semplicità di costruzione, l'economicità e la leggerezza della struttura ne consentono un'ampia applicazione.
Il processo prevede il rilascio dell'acciaio fuso quando la sua temperatura e composizione soddisfano le specifiche del tipo di acciaio da raffinare. Durante la spillatura dell'acciaio, è necessario prestare attenzione per evitare che le scorie entrino nella siviera.
Gli additivi utilizzati per regolare la temperatura, la composizione e la disossidazione dell'acciaio fuso vengono aggiunti alla siviera o al flusso di acciaio durante la spillatura, nota anche come lega di disossidazione.
1) Per alleviare il stress interno del materiale
2) Regolare la durezza del materiale (generalmente per aumentarla) con una leggera riduzione della plasticità.
Questo serve a preparare la lavorazione successiva. Ha un effetto simile a ricotturama mira a migliorare l'efficienza e a ridurre i costi.
