Ingxaki 1: Imingxuma kunye neZikhewu
1.Ukubonakala kwemingxuma emikhulu kwiindonga zei-crucibleezingekabhityanga ubukhulu becala zibangelwa zizithonga ezinzima, njengokugibisela ii-ingots kwi-crucible okanye impembelelo ebuthuntu xa ucoca intsalela.
2.Imingxuma emincinci idla ngokubangelwa kukuqhekeka kwaye ifuna ukumiswa kokusetyenziswa kunye nokukhangela iintanda.
Ingxaki yesi-2: Ukonakala
I-1.I-corrosion ye-metal page position ngaphakathi kwe-crucible ibangelwa izongezo kunye nee-oxide zetsimbi ezijikelezayo kwi-metal surface.
2.I-Corrosion kwiindawo ezininzi ngaphakathi kwe-crucible idla ngokubangelwa izinto ezinobungozi. Ngokomzekelo, ukongeza izongezo okanye ukutshiza ngokuthe ngqo izongezo kwi-crucible wall xa i-casting material ingafakwanga okanye inyibilike.
I-3.I-Corrosion kwi-bottom okanye i-bottom edge ye-crucible ibangelwa i-fuel kunye ne-slag. Ukusetyenziswa kwe-fuel ephantsi okanye ukushisa okuphezulu kakhulu kunokubangela umonakalo kwi-crucible.
I-4.Izongezo ze-concave ebusweni be-crucible zingena kwaye zigubungele udonga lwangaphandle lwe-crucible kunye nokushisa okuphezulu ngodonga lwangaphakathi lwe-crucible.
Ingxaki yesi-3: Ingxaki yokuhlanganisana
I-1.I-network cracks phezu komhlaba ifana nesikhumba sengwenya, ngokuqhelekileyo ngenxa yokuguga kunye nokufikelela kubomi benkonzo ye-crucible.
I-2.Isantya sokunyibilika kwezinto zokuphosa siyancipha
(1) I-crucible ayishushu kwaye iyabhaka ngokwenkqubo eqhelekileyo
(2) Ukuqokelelana kwe-slag ngaphakathi kwi-crucible
(3) I-crucible ifikelele kubomi bayo benkonzo
3. Ukuchithwa kweglaze
(1) Beka i-crucible epholileyo ngokuthe ngqo kwisithando somlilo esishushu sokufudumeza
(2) Ukufudumala ngokukhawuleza ngexesha lokufudumeza
(3) I-crucible emanzi okanye iziko
4. Xa kukho izinto zangaphandle ezinamathele kwi-bottom of the crucible, ukuba i-crucible ifakwe kumhlaba onzima, iya kubangela ukuba i-bottom of the crucible ikhuphe phezulu kwaye ivelise ukuqhekeka.
5. Ukuqhekeka ngezantsi, i-slag yentsimbi engqindilili ngaphakathi kwe-crucible ebangelwa ukwanda kwe-slag.
6. Umphezulu we-crucible ujika ube luhlaza kwaye uqala ukuthambisa.
(1) Ngexesha lokunyibilika kobhedu, i-slag phezu kwamanzi obhedu iphuphuma kudonga olungaphandle lwe-crucible.
(2) Ngenxa yokusebenza ixesha elide kwi-1600 degrees Celsius
7. Umda ongezantsi okanye ophantsi we-crucible entsha ukhutshwe kwi-crucible kwaye ufudumale ngokukhawuleza emva komswakama.
8. Ukuguqulwa kwe-crucible. Iindawo ezahlukeneyo ze-crucible zinokufumana ukwanda okungalinganiyo xa zifudunyezwa kumaqondo okushisa angalingani ngokugqithisileyo. Nceda musa ukutshisa i-crucible ngokukhawuleza okanye ngokungalingani
9. I-oxidation ekhawulezayo
(1) I-crucible ikwimo ephakathi kwe-315 ° C kunye ne-650 ° C ixesha elide.
(2) Ukusebenza okungafanelekanga ngexesha lokuphakamisa okanye ukuhamba, okubangela umonakalo kwi-glaze layer ye-crucible.
3
10. Udonga lwe-crucible luye lwaba luncinci kwaye lufikelele kubomi balo benkonzo, kwaye kufuneka lumiswe ekusebenziseni.
11. Izinto zetsimbi ezongezelelweyo ngexesha lokuqhuma kwe-crucible esetyenziswayo ayizange yomiswe.
