Ingqayi yetungsten yaseTshayina enyibilikayo evuzayo yetungsten enegquma uMvelisi kunye noMboneleli

imbiza enyibilikayo ye-tungsten etyumkileyo ye-tungsten eqholiweyo enekhava

imbiza yokunyibilika yetungsten ekhenkcezayo i-tungsten crucible eneqweqwe Umfanekiso ofakiweyo

Inkcazelo emfutshane:

I-tungsten crucibles and furnaces are commonly used in high-temperature applications such as metal casting, sintering, kunye nokuveliswa kweekeramics kunye nezinye izinto eziphezulu zokushisa. Indawo ephezulu yokunyibilika kweTungsten, i-thermal conductivity egqwesileyo kunye nokumelana neekhemikhali kwenza kube yinto efanelekileyo kwezi zicelo.

Isebenza njani i-crucible?

I-crucible yinqanawa eyenzelwe ukumelana namaqondo okushisa aphezulu, ngokuqhelekileyo asetyenziselwa ukunyibilika, i-calcine, okanye enye inkqubo yezinto eziphathekayo kumaqondo aphezulu. Iintsimbi zidla ngokwenziwa ngezinto ezinje ngegraphite, iiseramikhi, okanye isinyithi esichasayo njenge tungsten.

Ukusebenza okusisiseko kwe-crucible kubandakanya la manyathelo alandelayo:

1. Ukutywinwa: Umsebenzi oyintloko we-crucible uqulethe izinto ezicutshungulwayo, njengesinyithi, i-alloy okanye ezinye izinto, ngexesha lokufudumala okanye ukunyibilika. Ukumelana nobushushu obuphezulu be-crucible kuthintela izinto ekubalekeni okanye ukusabela kunye nokusingqongileyo.

2. Ukutshintshwa kobushushu: Xa ifakwe kwisithando somlilo okanye esinye isixhobo sokufudumeza, i-crucible ithatha ukushisa kwaye idlulisele kwizinto ezingaphakathi. Oku kuzisa imixholo ye-crucible kwiqondo lokushisa elifunekayo ukunyibilika, ukutshisa, okanye ezinye iinkqubo ze-thermal.

3. Ukhuseleko: I-crucible ibonelela ngokhuseleko kwizinto ezicutshungulwayo. Ngokomzekelo, kwimeko yokuncibilika kwesinyithi, ii-crucibles zinceda ukukhusela i-oxidation okanye ukungcoliswa kwesinyithi esityhidiweyo ngokubonelela indawo evaliweyo.

4. Ukugalela okanye ukuCasa: Emva kokuba izinto ezingaphakathi kwi-crucible zifikelele kwisimo esifunwayo, esifana nefom etyhidiweyo, i-crucible ingasetyenziselwa ukugalela okanye ukuphosa izinto kwi-mold okanye enye i-container ukuze iqhubekele phambili.

Kwimeko ye-tungsten crucibles, indawo yabo ephezulu yokunyibilika kunye nokuchasana nokuhlaselwa kweekhemikhali kubenza bafaneleke ukuphatha iinkqubo eziphezulu kakhulu zokushisa, ezifana nokunyibilika kweentsimbi eziphikisayo okanye ezinye izinto eziphakamileyo zokushisa.

Ngokubanzi, i-design kunye nezixhobo eziphathekayo ze-crucibles zibenza bakwazi ukumelana nokushisa okuphezulu, ziqulethe izinto eziphathekayo, ziququzelele ukutshintshwa kobushushu, kunye nokukhusela izinto ezicutshungulwayo kwizinto ezisingqongileyo, okwenza zibe sisixhobo esibalulekileyo kwiintlobo ezahlukeneyo zokushisa okuphezulu.

Kutheni i-crucible ifudunyezwa ngesiciko?

IiCrucibles zidla ngokufudunyezwa nesivalo sivaliwe ngenxa yezi zizathu zilandelayo:

1. Ukutywinwa: Isiciko sinceda ukutywina izinto ezicutshungulwayo kwi-crucible, ukukhusela ukuchithwa okanye ukutshiza xa ufikelela kumaqondo aphezulu. Oku kutywinwa kubaluleke kakhulu kwizinto ezinokusabela kunye nomoya ojikelezayo okanye kwiinkqubo ezifuna indawo elawulwayo.

2. Ukhuseleko: Isiciko sibonelela ngokukhusela izinto ezingaphakathi kwi-crucible ekungcoleni, kwi-oxidation, okanye kwezinye izinto zokusingqongileyo. Oku kubaluleke ngakumbi xa usebenza ngezinto ezinobuthathaka okanye xa usenza iinkqubo eziphezulu zokushisa ezifuna umoya othile.

3. I-Insulation: Ukugcina isiciko kwi-crucible kunceda ukugcina ukushisa ngaphakathi kwesitya, kukhuthaza ukufudumeza kwezinto kunye nokuthintela ukulahleka kobushushu kwindawo engqongileyo. Oku kubalulekile ukufezekisa ukufudumeza okuhambelanayo kunye nokulawulwa ngexesha lonyango lokushisa.

4. Ukulawulwa kwe-Atmosphere: Kwezinye iimeko, isiciko sinokunceda ukulawula umoya ngaphakathi kwe-crucible ukugcina ukubunjwa kwegesi ethile okanye uxinzelelo ngexesha lokufudumala. Oku kubalulekile ekuphatheni izinto ezithile kunye nokusabela kweekhemikhali.

Ngokubanzi, kwizicelo eziphezulu zokushisa, kuqhelekile ukutshisa izitshixo ezineziciko ukuqinisekisa ukutywinwa, ukukhuselwa, ukugquma, kunye nokulawulwa kwendawo yokucubungula.
