Kutheni iicrucible zegraphite ziqhekeka? Indlela yokusombulula ngayo?

Olu lulandelayo lucazululo oluneenkcukacha ezibangela iintanda:
1. Emva kokuba i-crucible isetyenziswe ixesha elide, udonga lwe-crucible lubonisa i-longitudinal cracks, kwaye udonga oluqhekezayo kwi-crack luncinci.
(uhlalutyo lwesizathu: i-crucible imalunga okanye ifikelele kubomi bayo benkonzo, kunye nei-crucibleUdonga luya kuba luncinci kwaye alukwazi ukuthwala amandla amaninzi angaphandle.)
2. I-crucible esetyenziswe okokuqala (okanye isondele kwintsha) ibonisa ukuqhekeka kunye nokuhamba ngaphantsi kwe-crucible.
(uhlalutyo lwesizathu: beka i-crucible epholileyo kwi-aubushushu obuphezuluUmlilo oshushu, okanye shushu umzantsi we-crucible ngokukhawuleza kakhulu xa i-crucible ikwimo yokupholisa. Ngokuqhelekileyo, umonakalo uya kukhatshwa yi-glaze peeling.)
3. Ukuqhekeka kwe-longitudinal ukusuka kumda ophezulu we-crucible.
(ucazululo lwesizathu: lwenziwa ngokufudumeza i-crucible ngokukhawuleza, ngakumbi xa isantya sokufudumala esisezantsi kunye nomda ophantsi we-crucible ukhawuleza kakhulu kunoko uphezulu. Umsebenzi wokutshata kumda ophezulu we-crucible ulula kwakhona. ukubangela umonakalo. I-crucible engafanelekanga okanye ukubetha kwinqanaba eliphezulu kuya kubangela umonakalo onzima kunye nomonakalo ocacileyo kumda ophezulu we-crucible.)
4. Ukuqhekeka kwe-longitudinal kwicala le-crucible (i-crack ayidluli phezulu okanye ngaphantsi kwe-crucible).
(ucazululo lwesizathu: luqhele ukwenziwa nguuxinzelelo lwangaphakathi. Umzekelo, xa intsimbi epholileyo eyimilo yentsimbi ifakwe ecaleni kwi-crucible, i-wedge-shaped cast material iya konakaliswa emva kokuba.ukwanda kwe-thermal.)
2, Ukuqhekeka okunqamlezayo kwe-graphite crucible:
1. Ukuvala ukuya ngaphantsi kwe-crucible (kunokubangela ukuba umzantsi we-crucible uwe)(uhlalutyo lwesizathu: lunokubangelwa yimpembelelo yeizinto ezinzima, njengokuphosa izinto zokuphosa kwi-crucible, okanye ukubetha umzantsi ngezinto eziqinileyo njengeIntsimbi yentsimbi. Olu hlobo lomonakalo luya kubangelwa ukwanda okukhulu kwe-thermal kwenye i-1b).
2. Malunga nesiqingatha sokuqhelaniswa ne-crucible.
(ucazululo lwesizathu: isizathu sinokuthi i-crucible ibekwe kwi-slag okanye isiseko esingafanelekanga. Xa ukhupha i-crucible, ukuba i-crucible clamping position isondele kakhulu phezulu kwaye i-force inkulu kakhulu, i-cracks iya kubonakala kwi-crucible. umphezulu we-crucible kwindawo engezantsi yei-crucible clamp)
3. Xa kusetyenziswa ii-crucibles series ze-SA, kukho iintanda ezinqamlezileyo kwindawo engezantsiumlomo wombhobho.
(uhlalutyo lwesizathu: i-crucible ayifakwanga ngokuchanekileyo. Xa ufaka i-crucible entsha, ukuba umhlaba ochasayo ugxininiswe ngokuqinileyo phantsi kwe-nozzle ye-crucible, amanqaku oxinzelelo aya kudibanisa kwi-nozzle ye-crucible ngexesha lokupholisa kunye nokunciphisa i-crucible ngexesha lokusebenza, okubangelwa kwiintanda).
