Izimbangela zokufa kweringi ziyinkimbinkimbi futhi kufanele zihlaziywe ngokuningiliziwe.Kodwa ingafingqwa ngokuyinhloko njengezizathu ezilandelayo.
1. Izinto ezisetshenziswa ekubunjweni kweringi kungesinye sezizathu ezibalulekile.Njengamanje, i-4Cr13 ne-20CrMnTid isetshenziswa kakhulu ezweni lakithi, elizinzile uma kuqhathaniswa.Kodwa umenzi wezinto ezibonakalayo uhlukile, ngenxa yezinto ezifanayo, izakhi zokulandelela zizoba negebe elithile, zizothinta ikhwalithi yesikhunta sendandatho.
2. Inqubo yokuqamba.Lesi isixhumanisi esibalulekile enqubweni yokukhiqiza isikhunta.Ukuze uthole isikhunta esiphezulu sensimbi ye-alloy, izidingo zokusabalalisa i-carbide yezinto ezibonakalayo kanye nezinye izakhiwo ze-metallographic zivame ukubekwa phambili.Kuyadingeka futhi ukulawula ngokuqinile ububanzi bezinga lokushisa lokubumba, ukwenza ukucaciswa kokushisisa okulungile, ukusebenzisa indlela efanele yokubumba, nokupholisa kancane noma ukucwiliswa okufika ngesikhathi ngemva kokufoja.Inqubo engajwayelekile kulula ukuholela ekuqhekekeni komzimba weringi.
3. Lungiselela ukwelashwa okushisa.Ngokwezinto ezihlukene kanye nezidingo ze-die, i-annealing, tempering kanye nezinye izinqubo zokulungiselela ukushisa ukushisa zisetshenziselwa ukwenza ngcono isakhiwo, ukuqeda ukukhubazeka kwesakhiwo sokubumba nokungenalutho, bese kuthuthukisa ukusebenza.Ngemuva kokulungiswa okufanele ukwelashwa kokushisa kwe-high carbon alloy steel die, i-carbide yenethiwekhi ingaqedwa, engenza i-carbide ibe spheroidized futhi icwengisiswe, futhi ukufana kokusabalalisa kwe-carbide kungakhuthazwa.Lokhu kusiza ukuqinisekisa ukucisha, izinga lokushisa, ukuthuthukisa impilo yesevisi yesikhunta.
Ukwelashwa kokushisa kwe-Pellet Mill
1. Ukunciphisa nokuthulisa.Lesi isixhumanisi esiyinhloko ekwelapheni ukushisa okufayo.Uma ukushisa ngokweqile kwenzeka ngesikhathi sokucisha ukushisa, ngeke nje kubangele ukuqina okukhulu kwe-workpiece, kodwa futhi kulula ukubangela ukuguqulwa nokuqhekeka ngesikhathi sokupholisa, okuzothinta kakhulu impilo yesevisi yesikhunta.Ukucaciswa kwenqubo yokwelashwa kokushisa kufanele kulawulwe ngokuqinile futhi ukwelashwa kokushisa kwe-vacuum kufanele kwamukelwe.Ukushisa kufanele kwenziwe ngesikhathi emva kokucisha, futhi ngokuvumelana nezidingo zobuchwepheshe ukuze kusetshenziswe inqubo yokushisa ehlukene.
2. I-annealing eqeda ukucindezeleka.Ifa kufanele ibhekane nokwelashwa okuqeda ukucindezeleka kwe-annealing ngemva komshini onzima, ukuze kuqedwe ukucindezeleka kwangaphakathi okubangelwa umshini onzima, ukuze kugwenywe ukubola noma ukuqhekeka okubangelwa ukucisha.Odabeni olunesidingo sokunemba okuphezulu, ludinga futhi ukwelashwa okwehlisa ukucindezeleka ngemva kokusila, okuzuzisayo ukuzinzisa ukunemba kokufa nokuthuthukisa impilo yesevisi.
Ukuvula imbobo rate of ring die
Uma izinga lokuvula imbobo yokufa kweringi liphezulu kakhulu, amathuba okuqhekeka kweringi azokhuphuka.Ngenxa yezinga elihlukile lokwelashwa kokushisa kanye nenqubo, kuzoba nomehluko omkhulu phakathi komkhiqizi weringi ngayinye.Ngokuvamile, umshini wethu wokugaya i-pellet ungathuthukisa izinga lembobo yokuvula ngo-2-6% ngesisekelo sesikhunta somkhiqizo wasekhaya wesigaba sokuqala, futhi ungaqinisekisa impilo yesevisi yesikhunta esiyindandatho.
Ukugqoka kwe-Pellet Mill
ukuqina okuthile futhi amandla ancishisiwe kuze kube yilapho engakwazi ukubekezelela ukucindezela kwe-granulation, ukuqhekeka kuzokwenzeka.Kutuswa ukuthi uma indandatho igqokwe ifike ezingeni lapho igobolondo le-roller groove lihambisana khona, indawo yokufa iringi kufanele ishintshwe ngesikhathi.
Uma isigayo se-pellet sifa ngenqubo ye-granulation, inani lempahla emshinini wokugaywa we-pellet alikwazi ukusebenza ku-100%.Nakuba isivuno se-ring die granulation siphezulu, kodwa isikhathi eside kangaka sokusebenza kwamandla aphezulu, futhi kuholela ekuqhekekeni kweringi.Sincoma ukulawula ku-75-85% womthwalo ukuqinisekisa impilo yesevisi yeringi iyafa.
Uma indandatho ifa futhi i-press roll icindezelwa kakhulu, kulula ukuqhekeka.Ngokuvamile, sidinga ukuthi ibanga eliphakathi kweringi kanye ne-press roll lilawulwe phakathi kuka-0.1-0.4mm.
okwahlukene
Kulula ukuqhekeka lapho izinto eziqinile ezifana nensimbi zivela ku-pelleting material.
Ukufakwa kwe-ring die kanye nomshini wokugaya
Ukufakwa kwe-ring ring akuqinile, kuzoba negebe phakathi kwe-ring ring kanye nomshini we-pelleting, futhi ukuqhekeka kwe-ring kufa nakho kuzokwenzeka ngesikhathi sokugaya.
Ngemuva kokwelashwa kokushisa, ukushona kweringi kuzokhubazeka kakhulu.Uma ingalungiswanga, indandatho yokufa izoqhekeka isetshenziswe.
Lapho umshini we-pelleting ngokwawo unamaphutha, njengokuthuthumela kwe-shaft eyinhloko yomshini wokugaya.
