Inkqubo yokuphosa i-centrifugal kunye neemfuno zobugcisa be-tin
ihlahla yobheduikakhulu ibandakanya le miba ilandelayo:
Inkqubo yokusakaza:
Inkqubo ye-centrifugal casting ye-tin bronze bushing yindlela yokuphosa ii-castings ezikhethekileyo ezifana nezangqa, iityhubhu, iisilinda, i-bushing, njl.njl. ngokusebenzisa amandla aphakathi. Ngethuba lenkqubo yokuphosa, i-alloy ye-liquid izaliswe kwaye iqiniswe phantsi kwesenzo samandla e-centrifugal ukufumana i-casting. Iimpawu zale ndlela yokuphosa isiphumo esihle sembuyekezo yentsimbi, isakhiwo sangaphandle esishinyeneyo sokuphosa, ukubandakanywa okumbalwa okungeyona isinyithi, kunye neempawu ezintle zoomatshini.
Iimfuno zobugcisa:
1. Ikhonkco lokunyibilikisa: Intlawulo kufuneka yohliswe kwaye irulwe, igcinwe icocekile, kwaye into egqumayo efana namalahle kufuneka yongezwe emazantsi eziko lombane. Ubushushu bolwelo lobhedu kufuneka balawulwe ngokungqongqo ngexesha lokunyibilikisa. Ngokuqhelekileyo kuyimfuneko ukwenza i-deoxidize i-alloy kwangaphambili kwiqondo lokushisa eliphezulu le-1150 ~ 1200 ℃, kwaye uyifudumeze malunga ne-1250 ℃ ukwenzela i-deoxidation yokugqibela kunye nokucocwa.
2. Ukulawulwa kwezinto eziphathekayo: Xa uphonsa ubhedu obucocekileyo kunye ne-tin bronze, kufuneka kuqwalaselwe ingqalelo kwisithintelo somxholo wokungcola, kwaye ugweme ukusebenzisa izixhobo zetsimbi, ii-crucibles eziye zanyibilika ezinye i-alloys zethusi, kunye nezinto ezihlaziyiweyo ezihlaziyiweyo. I-tin bronze bushing inerhasi eyomeleleyo yokufunxa. Ukunciphisa i-gas absorption, kufuneka bancibilike ngokukhawuleza kwi-oxidizing ebuthakathaka okanye i-oxidizing atmosphere kwaye phantsi kokukhuselwa kwe-arhente yokugubungela.
Nceda uqaphele ukuba ezi nkcukacha zingentla zenzelwe ireferensi kuphela. Inkqubo ethile yokuphosa kunye neemfuno zobugcisa zinokulungelelaniswa ngokwemeko yesicelo esithile, iipropati eziphathekayo kunye neemfuno zabathengi. Ekusebenzeni kwangempela, imimiselo yenkqubo echaphazelekayo kunye neenkqubo zokusebenza zokhuseleko kufuneka zilandelwe ngokungqongqo ukuze kuqinisekiswe inkqubela phambili yenkqubo yokuvelisa kunye nomgangatho ozinzile wemveliso.
