Nalane ea Nts'etsopele ea Silicon carbide crucible

Lefapheng la metallurgy, nalane ea tlhahiso ea Silicon carbide crucible e sebelisetsoang ho qhibilihisa litšepe tse senang ferrous e ka saloa morao ho tloha lilemong tsa bo-1930. Ts'ebetso ea eona e rarahaneng e kenyelletsa ho silakanya thepa e tala, ho kopanya, ho ohla ka letsoho kapa ho etsa roll, ho omisa, ho thunya, ho tlotsa oli le ho thibela mongobo. Lisebelisoa tse sebelisoang li kenyelletsa graphite, letsopa, pyrophyllite clinker kapa high-alumina bauxite clinker, phofo ea monosilica kapa phofo ea ferrosilicon le metsi, tse kopantsoeng ka tekanyo e itseng. Ha nako e ntse e ea, silicon carbide e kenyelelitsoe ho ntlafatsa conductivity ea mocheso le ho ntlafatsa boleng. Leha ho le joalo, mokhoa ona oa setso o na le tšebeliso e phahameng ea matla, potoloho e telele ea tlhahiso, le tahlehelo e kholo le deformation sethaleng sa sehlahisoa se felileng.

Ka lehlakoreng le leng, ts'ebetso ea kajeno ea ho etsa crucible e tsoetseng pele haholo ke ho hatella ka isostatic. Theknoloji ena e sebelisa graphite-silicon carbide crucible, e nang le phenolic resin, tar kapa asphalt e le ntho e tlamang, le graphite le silicon carbide e le lisebelisoa tse ka sehloohong tse tala. Sehlahisoa se hlahisoang se na le porosity e tlase, sekhahla se phahameng, sebopeho se ts'oanang le khanyetso e matla ea kutu. Ho sa tsotellehe melemo ena, ts'ebetso ea mollo e ntša mosi o kotsi le lerōle, e leng se bakang tšilafalo ea tikoloho.

Phetoho ea tlhahiso ea Silicon carbide crucible e bonts'a ts'ebetso e tsoelang pele ea indasteri ea ts'ebetso, boleng le boikarabello ba tikoloho. Ha theknoloji e ntse e hatela pele, ho tsepamisitsoe maikutlo ho nts'etsopele ea mekhoa ea ho fokotsa tšebeliso ea matla, ho khutsufatsa potoloho ea tlhahiso le ho fokotsa tšusumetso ea tikoloho. Baetsi ba Crucible ba ntse ba hlahloba lisebelisoa le mekhoa e mecha ea ho finyella lipakane tsena, ka sepheo sa ho leka-lekanya pakeng tsa moetlo le sejoale-joale. Ha tlhokahalo ea ho qhibilihisa tšepe e se nang ferrous e ntse e hola, nts'etsopele ea tlhahiso ea crucible e tla bapala karolo ea bohlokoa ho bopeng bokamoso ba metallurgy.
