結(jié)構(gòu)件

難熔金屬具有高熔點(diǎn)、低蒸汽壓、低熱膨脹系數(shù)，以及出色的高溫強(qiáng)度和抗蠕變性能，通過合金化，使得其加工性能和高溫性能進(jìn)一步提高，延長產(chǎn)品的使用壽命。因此鎢、鉬、鉭、鈮金屬作為結(jié)構(gòu)材料、發(fā)熱體和保溫層等廣泛應(yīng)用于各類高溫爐。

產(chǎn)品介紹

產(chǎn)品用途：

難熔金屬由于其良好的高溫力學(xué)性能，在高溫爐內(nèi)經(jīng)常作為結(jié)構(gòu)材料，起到支撐保護(hù)作用。

Application:

Refractory metals are often used as a structural material to play a supporting and protective role in the high-temperature furnace for its good high-temperature mechanical properties.
