| 摘 要： | 由于玻璃模具应具有良好的抗氧化性和热疲劳性 ,通过对 RQTSi4Cu2 Al2 ,RQTSi4Cu4Al4和 RQTSi5Mo三种耐热铸铁的抗氧化性和热疲劳性模拟实验结果的分析 ,找出了一种比较适合玻璃模具的材料 ,并且初步研究了几种耐热铸铁的氧化组织变化规律。发现硅铝铜球铁和硅钼球铁在高温长时间氧化时 ,在氧化皮下形成了一层无石墨的铁素体层 ,且温度越高 ,时间越长 ,铁素体层越厚。

| Abstract: | Since glass mold must have good resistauce to oxidation and heat fatigue,a fit material for glass mold has been found in analog experiment of RQTSi4Cu2A12?RQTSi4Cu4A14 and RQTSi5Mo. At the same time,oxide organization law of these refractory cast iron have been initially studied. When RQTSi4Cu4A14 and RQTSi5Mo are oxidized in high temperature and long time,a layer of Ferrite without graphite is formed,and the longer the time,the higher the temperature,the thicker the ferrite without graphite. |
