Quali sono i comuni materiali di rivestimento refrattari EAF?<\/p>\n

Rivestimento refrattario EAF<\/strong><\/a> \u00e8 solitamente costituito da materiali refrattari alcalini, integrati da materiali neutri o acidi, ed \u00e8 configurato in modo diverso a seconda delle condizioni di lavoro delle parti:<\/p>\n

Il mattone al carbonio di magnesio \u00e8 il materiale di base, composto da ossido di magnesio (60%~90%) e grafite (10%~30%), con una forte resistenza alle alte temperature (superiori a 1700\u2103), agli shock termici e all'erosione delle scorie, ed \u00e8 utilizzato in parti chiave come l'area della linea delle scorie e il fondo del forno.<\/p>\n

\"\"<\/p>\n

Il mattone di magnesio e calcio contiene ossido di magnesio e ossido di calcio, in grado di purificare le scorie e adatto alla fusione di acciaio pulito come l'acciaio inossidabile, ma richiede un trattamento a prova di umidit\u00e0.<\/p>\n

Il mattone ad alto tenore di allumina (allumina 48%~90%) \u00e8 un materiale neutro con buona resistenza agli shock termici e basso costo. Viene utilizzato in aree non critiche ad alta temperatura, come la parte superiore del forno e l'uscita dell'acciaio.<\/p>\n

\"\"<\/p>\n

I materiali amorfi, come i materiali da costruzione e i colabili, sono utilizzati per riparazioni in loco o per parti strutturali complesse.<\/p>\n

La tendenza generale \u00e8 verso una bassa carbonizzazione e una lunga durata per soddisfare le esigenze di protezione ambientale e di efficienza della fusione.<\/p>\n

Area della linea delle scorie<\/td>\nL'erosione delle scorie \u00e8 la pi\u00f9 grave e le fluttuazioni di temperatura sono notevoli.<\/td>\nMattoni di carbonio di magnesia ad alto contenuto di grafite, mattoni di carbonio di calcio di magnesia<\/td>\n<\/tr>\n
Parete del forno<\/td>\nRadiazioni ad alta temperatura, metallo fuso e scorie di corrosione<\/td>\nMattoni al carbonio di magnesia a medio e basso contenuto di grafite, mattoni ad alto contenuto di allumina<\/td>\n<\/tr>\n
