Iindaba - Inkqubo yokuVeliswa kweMibhobho yentsimbi yeNtsimbi: Inkqubo engqongqo yokuKhanya imibhobho ekumgangatho ophezulu

Kwimizi-mveliso yanamhlanje, imibhobho yentsimbi ye-ductile isetyenziswa ngokubanzi kunikezelo lwamanzi, ukuhambisa amanzi, ukuhanjiswa kwerhasi kunye namanye amasimi ngenxa yeempawu zabo ezintle zoomatshini kunye nokumelana nokugqwala. Ukuze kuqinisekiswe umgangatho ophezulu kunye nokuthembeka okuphezulu kwemibhobho yensimbi ye-ductile, inkqubo yabo yokuvelisa kufuneka ilawulwe ngokungqongqo kwaye iqhutywe kakuhle. Ukusuka kulungiselelo kunye ne-spheroidization yesinyithi esinyibilikisiweyo, ukuya kwi-centrifugal casting, annealing, kunye neenkqubo zokugqiba ezifana nokutshiza i-zinc, ukugaya, uvavanyo loxinzelelo lwe-hydraulic, ukufakwa kwesamente kunye nokutshiza nge-asphalt, ikhonkco ngalinye libalulekile. Eli nqaku liza kwazisa inkqubo yokuvelisaI-Ductile Cast yentsimbi yombhobhongokweenkcukacha, kwaye ubonise indlela yokuqinisekisa ukuba umbhobho ngamnye unokuhlangabezana nemigangatho yamazwe ngamazwe kunye neemfuno zokusetyenziswa ngokwenene ngolawulo lwezenzululwazi kunye neendlela eziphambili zobugcisa, kunye nokubonelela ngeziqinisekiso zeziseko ezithembekileyo kwiiprojekthi zobunjineli ezahlukeneyo.

1. Ukulungiswa kwentsimbi etyhidiweyo
Ukulungiswa kwentsimbi enyibilikisiweyo kunye ne-Spheroidization: Khetha umgangatho ophezulu wokuphosa intsimbi yehagu njengemathiriyeli ekrwada, efana nentsimbi yehagu yodidi oluphezulu, eneempawu ze-P ephantsi, i-S ephantsi, kunye ne-Ti ephantsi. Ngokwengcaciso yobubanzi bombhobho oza kuveliswa, izinto ezihambelanayo zongezwa kwiziko lombane eliphakathi, eliguqula intsimbi etyhidiweyo kwaye iyifudumeze kubushushu obufunwa yinkqubo, kwaye yongeza i-agent spheroidizing for spheroidization.
Ulawulo Lomgangatho Wentsimbi eshushu: Kwinkqubo yokulungiswa kwentsimbi etyhidiweyo, umgangatho kunye nokushisa kwekhonkco nganye kulawulwa ngokungqongqo. Isithando somlilo ngasinye kunye nengxowa nganye yentsimbi etyhidiweyo kufuneka ihlalutywe nge-spectrometer yokufunda ngokuthe ngqo ukuqinisekisa ukuba isinyithi esityhidiweyo sihlangabezana ngokupheleleyo neemfuno zokuphosa.

Inkqubo yokuvelisa umbhobho we-Ductile cast

2. I-Centrifugal Casting
Ukuphoswa ngamanzi kweMetal Mold Centrifuge Casting: I-centrifuge yentsimbi epholileyo yamanzi isetyenziselwa ukuphosa. Ubushushu obuphezulu bentsimbi enyibilikisiweyo bugalelwa ngokuqhubekayo kumbhobho ojikelezayo wesantya esiphezulu. Ngaphantsi kwesenzo samandla e-centrifugal, intsimbi etyhidiweyo isasazwa ngokulinganayo kudonga lwangaphakathi lombhobho wokubumba, kwaye intsimbi etyhidiweyo iqiniswa ngokukhawuleza ngokupholisa kwamanzi ukuze yenze umbhobho wentsimbi we-ductile. Emva kokuba kugqitywe ukuphosa, umbhobho wokuphosa uyahlolwa ngoko nangoko kwaye ulinganiswe ubungakanani bokuphosa iziphene ukuqinisekisa umgangatho wombhobho ngamnye.
Unyango lwe-Anealing: IqongaUmbhobho wentsimbiemva koko ibekwe kwiziko lokutshisa i-annealing unyango ukuphelisa uxinzelelo lwangaphakathi olwenziwe ngexesha lenkqubo yokuphosa kunye nokuphucula isakhiwo se-metallographic kunye neepropati zomatshini zombhobho.
Uvavanyo lokuSebenza: Emva kwe-annealing, umbhobho we-iron ductile uxhomekeke kuluhlu lweemvavanyo eziqinileyo zokusebenza, kubandakanywa uvavanyo lwe-indentation, uvavanyo lwembonakalo, uvavanyo lwe-flattening, uvavanyo lwe-tensile, uvavanyo lobunzima, uvavanyo lwe-metallographic, njl.

3. Ukugqiba
Zinc Ukutshiza: Umbhobho wentsimbi we-ductile uphathwa nge-zinc ngokusebenzisa umatshini wokutshiza wombane ophezulu. Uluhlu lwe-zinc lunokwenza ifilimu ekhuselayo kumphezulu wombhobho ukunyusa ukuxhathisa ukubola kombhobho.
Ukusila: UyafanelekaUmbhobho wokukhupha amanzi wentsimbizithunyelwa kwisikhululo sesithathu sokusila ukuze zihlolwe inkangeleko, kwaye isokethi, i-spigot kunye nodonga lwangaphakathi lombhobho ngamnye ziyagudiswa kwaye zicocwe ukuqinisekisa ukuba mcaba kunye nokuphela komphezulu wombhobho kunye nokutywinwa kojongano.
Uvavanyo lweHydrostatic: Imibhobho elungisiweyo iphantsi kovavanyo lwe-hydrostatic, kwaye uxinzelelo lovavanyo luyi-10kg / cm² ngaphezu komgangatho wamazwe ngamazwe we-ISO2531 kunye nomgangatho waseYurophu, ukuze kuqinisekiswe ukuba imibhobho inokumelana noxinzelelo olwaneleyo lwangaphakathi kwaye ihlangabezane neemfuno zoxinzelelo ekusebenziseni ngokwenene.
Uyilo lwesamente: Udonga lwangaphakathi lombhobho lufakwe kwi-centrifugally ngesamente ngumatshini we-sement owenziwe kabini. Udaka lwesamente olusetyenzisiweyo luye lwahlolwa ngokungqongqo umgangatho kunye nolawulo lomlinganiselo. Yonke inkqubo yokugqoka ilawulwa yikhompyutheni ukuqinisekisa ukufana komgangatho kunye nokuzinza kwe-cement lining. Imibhobho efakwe ngesamente iyanyangwa njengoko ifunekayo ukuze kuqiniswe ngokupheleleyo umgca wesamente.
Ukutshiza nge-asphalt: Imibhobho enyangisiweyo ifudumeza kuqala phezu komhlaba, kwaye emva koko i-asphalt itshizwe ngesitshizi esizenzekelayo esizitishi ezimbini. Ukugquma kwe-asphalt kwandisa ngakumbi amandla okulwa nokubola kwemibhobho kunye nokwandisa ubomi benkonzo yemibhobho.
Uhlolo lokugqibela, ukuPakisha kunye noGcino: Imibhobho etshizwe nge-asphalt iphantsi kokuhlolwa kokugqibela. Kuphela yimibhobho ekufanelekele ngokupheleleyo ukutshizwa ngamanqaku, ize ke ipakishwe ize igcinwe njengoko kufunwa, ilindele ukuthunyelwa kwiindawo ngeendawo ukuze isetyenziswe.
