ICarbon Crucible ngamagorha angazange adunyiswe wokuphoswa kwentsimbi. Ngapha koko, badlala indima ebalulekileyo ekujonganeni neminye imiceli mngeni yokunyibilika kweziseko kunye neendawo ezinobushushu obuphezulu. Ubusazi ukuba ezi crucibles ziyakwazi ukumelana namaqondo obushushu angaphezu kwe-1600°C? Asiyonto incinci leyo! Ukomelela kwabo, kudityaniswa ne-thermal conductivity ekhethekileyo, kubenza babaluleke kakhulu kwihlabathi lesinyithi.

Umnqophiso wethu uya kuba ngumthengisi ovelisa izinto ezintsha zedijithali kunye nezixhobo zonxibelelwano ngokunikezela ngesakhiwo esongezelelweyo, ukuveliswa komgangatho wehlabathi, kunye nezakhono zenkonzo yeCarbon Crucible, Inkampani yethu iya kuqhubeka nokuthobela "umgangatho ophezulu, ohloniphekileyo, umsebenzisi wokuqala" umgaqo ngentliziyo iphela. Samkela ngokufudumeleyo abahlobo abavela kuzo zonke iinkalo zobomi ukuba bandwendwele kwaye banike isikhokelo, basebenze kunye kwaye benze ikamva eliqaqambileyo!
I-Carbon Bonded Silicon Carbide Crucibles isetyenziswa ngokubanzi kwiindawo zokunyibilikisa kunye nokuphosa iintsimbi ezingafaniyo zesinyithi ezifana nobhedu, i-aluminium, igolide, isilivere, ilothe, i-zinc kunye ne-alloys. Ukusetyenziswa kwezi crucibles kubangela umgangatho ohambelanayo, ubomi benkonzo ende, ukunciphisa kakhulu ukusetyenziswa kwepetroli kunye nokuqina komsebenzi. Ukongeza, iphucula ukusebenza kakuhle kwaye ibonelela ngeenzuzo ezigqwesileyo kwezoqoqosho.

Izixhobo kunye noKwakha
Iicrucibles zegraphite zenziwe ngezinto ezininzi:

• I-graphite (45-55%): Icandelo eliphambili, elibonelela ngokugqithiswa kobushushu kunye nokuzinza kwe-thermal.
• I-Silicon carbide, i-silica, kunye nodongwe: Ezi zixhobo zongeza amandla omatshini we-crucible kunye nokuxhathisa ukubola, ngakumbi kwiimeko zobushushu obugqithisileyo.
• Isibophelelo sodongwe: Iqinisekisa umanyano olululo lwemathiriyeli, inika i-crucible imilo yayo kunye nokuthembeka kwesakhiwo.

Ubungakanani besuntswana legraphite elisetyenzisiweyo nalo liyahluka ngokuxhomekeke kubukhulu be-crucible kunye nenjongo. Ngokomzekelo, ii-crucibles ezinkulu zisebenzisa i-graphite e-coarser, ngelixa ii-crucibles ezincinci zifuna i-graphite ephucukileyo ukwenzela ukuchaneka okungcono kunye nokusebenza.

Usetyenziso lweGraphite Crucible
I-graphite carbon crucibles isetyenziswa ngokubanzi kumacandelo ahlukeneyo:

• Ukuphoswa kwentsimbi engeyiyo i-ferrous: Kufanelekile kwiintsimbi ezifana nobhedu, igolide, isilivere kunye nobhedu ngenxa ye-coefficient ephantsi yokwandiswa kwe-thermal.
• I-furnaces induction: Kwezinye iimeko, ii-crucibles ziyilelwe ukuba zisebenze kunye neefrikhwensi ezithile zesithando somlilo ukwandisa ukusebenza kakuhle kwamandla kunye nokulawula ubushushu.
• Ukusetyenzwa kweekhemikhali: Uzinzo lwazo lweekhemikhali luzenza zilungele ukusetyenziswa kwindawo ezivezwe kwizinto ezineasidi okanye zealkaline.

Iingcebiso zokuLondoloza okuBalulekileyo
Ukwandisa ubomi be-graphite carbon crucible, ukhathalelo olufanelekileyo kunye nokugcinwa kubalulekile:

1. Ukupholisa: Qinisekisa ukuba i-crucible ipholisa ngokupheleleyo phambi kokugcinwa ukunqanda ukothuka kwe-thermal.
2. Ukucoca: Njalo susa intsalela yentsimbi kunye ne-flux emva kokusetyenziswa ngalunye ukukhusela ungcoliseko.
3. Ukugcinwa: Gcina i-crucible kwindawo eyomileyo, kude nemithombo yokushisa ngokuthe ngqo, ukuphepha ukufunxa ukufuma, okunokubangela ukuthotywa kwesakhiwo.
