Kuvandudzwa kweGerman Vacuum Furnace C/C Composite Hot Zone: Anti-Deformation uye Refu
Pfupiso yeVatungamiriri
Kuvandudzwa kwenyaya yefurnace yekudzima gasi ine simba repamusoro yeGerman vacuum (1350°C / 20bar): VET Energy yakashandisa mabhoti eC/C akagadzirwa nemaoko, mafuremu akareruka anotakura mutoro, uye CVD SiC-coated graphite heating rods kuti itsive zvikamu zvechinyakare zvemolybdenum negrafiti inorema. Izvi zvakagadzirisa zvachose kudzika kwekupisa kwakanyanya uye kupwanyika kakawanda. Kushanda kwakayerwa: huremu hweframe hwakaderedzwa ne62%, kugona kwekutakura kwakawedzerwa ne35%, kushandiswa kwesimba rimwe chete kwakadzikira ne22%, hupenyu hwebasa rezvikamu hwakawedzerwa nekanopfuura katatu, uye kuchengetedza mari pagore kwakapfuura €22,000.

Mukugadzirisa gasi rine simba guru (HPGQ) uye kupisa kwakanyanya, mashandiro ekupisa uye huwandu hwekupisa hwezvikamu zvepakati pekupisa zvinotarisa zvakananga kugadzirwa kwemidziyo uye kunaka kwekudzima kwezvishandiso. Zvitofu zvevacuum zvechinyakare zvinowanzo vimba neheavy molybdenum (Mo) kana graphite fixtures pamwe chete nema graphite bolts akajairwa. Kana kupisa kwakanyanya pa1200°C–1400°C uye kumanikidzwa kwekudzimisa gasi rine simba remhepo ine simba re10–20 bar, izvi zvigadzirwa zvechinyakare zvinotambura nekudzikama kwakanyanya, kuputsika, uye oxidative spall.
Chidzidzo ichi chinotsanangura kuti VET Energy yakabatsira sei mutengi wekuGerman wekurapa kupisa kuti akunde matambudziko ekupisa kwakanyanya uye kushandisa simba rakawanda kuburikidza nekushandisa simba rakawanda.Mabhaudhi eC/C akagadzirwa, mafuremu akareruka ane mativi akawanda, uyeCVD SiC/TaC yakaputirwa negraphite yekudziyisa tsvimbo.
Mufananidzo 1: Furemu ine simba guru reC/C ine machira akawanda akareruka uye mabhoti eC/C akabatanidzwa muchoto cheGerman chekudzimisa gasi chine simba guru.Mafuremu eCarbon/Carbon Composite uye Mabhoti eCarbon Anokunda Sei Kukwira Kwemhepo Nekupwanyika Kwemhepo Yakanyanya?
