Izici zeshidi le-molybdenum

I-Molybdenum isetshenziswa kabanzi embonini yokucubungula. Isikhunta esisetshenziswa ekushiseni okuphezulu siyashiswa futhi ukucindezelwa kokushintshana komshini kuholela ekuqhekekeni kokukhathala kwezinto. Ukusebenzisa i-molybdenum noma i-molybdenum esekelwe i-alloy ene-coefficient encane yokwandisa okushisayo, ukuqhutshwa kwe-thermal okuqinile namandla amahle okushisa aphezulu kungandisa kakhulu impilo yesevisi yefa. Lapho inkampani ye-gkn yase-UK ifa izingxenye ezinhle njengekesi lewashi, impilo yesevisi ingafinyelela izikhathi ezingu-5000, ngokuvamile izikhathi ezingu-3000. Emkhiqizweni okhiqizayo, ipuleti le-tungsten, i-tungsten crucible ne-molybdenum crucible zisebenzisa isikhunta se-molybdenum alloy, esinde ngokuphindwe izikhathi ezingu-15 kunensimbi yokuqala enesivinini esiphezulu kanye nesikhunta sensimbi esinensimbi.

Lapho i-isothermal ihlanganisa i-refractory superalloy, i-molybdenum alloy die ingasetshenziswa ku-1200 ℃. Ngenxa yokuqina kwayo okuphezulu namandla okukhathala okubanda kakhulu namandla ashisayo, ingxubevange esekelwe kwi-molybdenum ivame ukusetshenziswa njengepulaki futhi ishone emshinini wokubhoboza wamapayipi ongenamthungo, futhi ukuphila kwayo kuyinde ngokuphindwe izikhathi ezingamakhulu kune-3Cr2W8V die steel. Ishidi le-Molybdenum lihlukaniswe ngeshidi le-molybdenum elikhanyayo (PCC) kanye neshidi le-molybdenum (GCC).

Isici seshidi le-molybdenum ukuthi lingakwazi ukulawula ngesandla umbala, usayizi wezinhlayiyana, izici ezingaphezulu, ukuhlakazeka, i-rheology, i-thixotropy nefomu lekristalu. Ngaphezu kwalokho, ishidi le-molybdenum linokuhlanzeka okuphezulu kwamakhemikhali, inertia yamakhemikhali aqinile nokuzinza okuhle kokushisa, futhi ngeke libole ngaphansi kuka-400 ℃. Ngaphezu kwalokho, ishidi le-molybdenum libuye libe nezinzuzo zezinga eliphansi lokumuncwa kwamafutha, ubulukhuni obuphansi, inani elincane lokugqoka, elingenabuthi, elingenaphunga, elingenakunambitheka, ukuhlakazeka okuhle nokunye.
