Kutheni usebenzisana nathi?

Xa usikhetha, ufumana ngaphezu kwemveliso-ufumana iqabane.

• Ubungcali: Amashumi eminyaka yamava kwishishini le-Foundry.
• Ukwenza ngokwezifiso: Izisombululo ezilungiselelwe ukuhlangabezana neemfuno zakho ezithile.
• Inkxaso: Ukusuka kukhetho ukuya kufakelo, sikunye nawe onke amanyathelo endlela.

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.

1. Iimpawu eziphambili zeUkunyibilika kweeCrucible zeMetal

• Ukumelana nobushushu obuphezulu: Yenzelwe ukujamelana namaqondo okushisa aphezulu, i-crucible metal crucibles zenzelwe ukujongana neemfuno zetsimbi ezahlukeneyo, ukuqinisekisa ukhuseleko kunye nokusebenza kakuhle.
• I-Thermal Conductivity egqwesileyo: Izinto ezisetyenzisiweyo zikhuthaza ukuhanjiswa kobushushu okukhawulezayo kunye okufanayo, ukunciphisa amaxesha okunyibilika kunye nokusetyenziswa kwamandla.
• Ukumelana ne-Corrosion: Ngezinto ezixhathisa i-oxidation kunye nokuhlaselwa kweekhemikhali, ezi crucibles ziye zandisa ubomi benkonzo, nto leyo iguqulela kwindleko yokonga ngexesha.
• I-Coefficient ephantsi yoKwandiswa kwe-Thermal: Olu phawu lunciphisa umngcipheko wokuqhekeka ngexesha lokuhamba ngebhayisikili ye-thermal, ukuqinisekisa ukuthembeka kwinkqubo yokunyibilika.
• I-Smooth Inner Wall: Olu phawu loyilo luthintela isinyithi ukuba singabambeleli kwindawo ye-crucible, iququzelele ukugalela lula kunye nokucoca.2. Izinto eziKhethekileyo zokuNyibilikisa iiCrucible zeMetal
  Xa ukhetha i-crucible yesinyithi enyibilikayo, qwalasela ezi zinto zilandelayo:
  • I-Silicon Carbide Graphite: Esi sixhobo sinikezela nge-thermal conductivity ekhethekileyo kwaye ixhathisa kakhulu ukutshitshiswa kwe-thermal, iyenza ilungele ukusetyenziswa kobushushu obuphezulu. Isebenza ngokukodwa kwiindawo zokunyibilika kwe-induction.
  • I-Clay Graphite: Eyaziwayo ngokuhlala kwayo kunye nokusebenza kakuhle, i-clay graphite crucibles ifanelekile ukunyibilika kwenjongo jikelele. Babonelela nge-conductivity entle ye-thermal kwaye bahlala besetyenziselwa imisebenzi yesiseko yemveli.
  • I-Graphite ecocekileyo: Eyaziwa ngokuba yi-thermal kunye ne-electrical conductivity egqwesileyo, i-graphite crucibles ecocekileyo ifanelekile kwizicelo ezifuna ukuchaneka okuphezulu kunye nokungcoliseka okuncinci. Ziyagqwesa kwiindawo ezinobushushu obuphezulu kwaye ziluncedo kakhulu kwiintsimbi ezixabisekileyo.

  3. Ukuhambelana neentlobo ze-Furnace
  Iintsimbi ezinyibilikayo ezinyibilikayo ziguquguquka kwaye zinokusetyenziswa kwiindidi ezahlukeneyo zesithando somlilo, kubandakanya:

  • I-Induction Furnaces: Ilungele ulawulo oluchanekileyo malunga nobushushu obunyibilikayo, ibenza bagqibelele ukuphoswa kwentsimbi ekumgangatho ophezulu.
  • I-Resistance Furnaces: Ezi ziko zibonelela ngeendawo ezizinzileyo, eziyimfuneko ekunyibilikeni okungaguqukiyo.
  • IiFurnaces zeVacuum: Ibalulekile kwizinto ezinobuthathaka, ezi ziko zinciphisa umngcipheko we-oxidation kunye nokungcoliseka.
