Cr20ni80 NiCr8020 Nicr Alloy Nichrome Waya yekupisa Element Mufananidzo Wakaratidzwa

Waya yeCr20ni80 NiCr8020 Nicr Alloy Nichrome yeHeating Element

Tsananguro pfupi:

Chinhu chinonzi NiCr8020 chine nhamba 2.4869 chinoshandiswa muchimiro chezvidimbu, machira, machubhu newaya zvezvikamu zvekuvaka furnace uye maconductor ekupisa. I alloy ye nickel-chromium heating conductor yekushandisa tembiricha inosvika 1150 °C uye inowanzo kuve nezvimwe zvinhu zve rare earths kuti irambe yakasimba mukuoxidation, kunyanya nekuchinja-chinja kana kuchinja tembiricha zvakanyanya. Kuramba kwekuora kwemhepo pa20 °C kwakakwira kusvika patembiricha yepamusoro yekushanda, kuramba mhepo nemamwe magasi ane oxygen pamwe nemagasi ane nitrogen ane low-oxygen kwakakwirawo, asi kwakaderera pakuoxidation pamwe nekuderedza magasi ane sulphur. Kuramba kwekuoxidation kwakakwira. Kushandiswa kwemaoven emagetsi eindasitiri, maoven enamelling, midziyo yemumba, maheater ekuchengetedza ehusiku.
