Ungakuqonda kanjani kahle ukusetshenziswa nokuhlukaniswa kwama-carbide rolls

Eminyakeni yakamuva,i-tungsten carbide rollerziye zasetshenziswa kabanzi ekukhiqizeni insimbi nokusebenza kwayo okuhle kakhulu.Kodwa-ke, kusenezinkinga ezimbalwa ekukhiqizeni nasekusetshenzisweni kwemiqulu ye-tungsten carbide kanje:

(1) Ucwaningo nokuthuthukiswa kwezinto ezintsha ze-carbide composite roll shaft.Njengoba imboni yokugoqa insimbi iqhubeka nokubeka phambili izidingo ezintsha neziphakeme zemiqulu, impahla evamile ye-ductile iron roll izoba nzima ukumelana namandla amakhulu okugoqa futhi idlulisele i-torque enkulu, ngenxa yalesi sizathu, kuyadingeka ukuthuthukisa i-carbide composite esebenza kahle kakhulu. roll impahla.
(2) Enqubweni yokukhiqiza amaroli ayinhlanganisela, ingcindezi yokushisa eyinsalela phakathi kwensimbi yongqimba lwangaphakathi kanye ne-carbide yongqimba yangaphandle ngenxa yokungezwani kokwanda kokushisa kufanele kuncishiswe noma kuqedwe ngangokunokwenzeka.I-carbide enosimendeukucindezeleka okushisayo okusele kuyisici esibalulekile esithinta impilo yesevisi yama-rolls ayinhlanganisela, ngakho-ke, i-coefficient yomehluko wokunweba okushisayo phakathi kwensimbi ekhethiwe yangaphakathi kanye nongqimba lwangaphandle lwe-carbide enosimende kufanele ibe mncane ngangokunokwenzeka, kuyilapho kucatshangelwa ukuthi kungenzeka ukwelashwa kokushisa roll ring ukuqeda ukucindezeleka okushisayo okusele.
(3) Njengoba amandla aginqikayo, isikhashana esiginqikayo kanye nezakhiwo zokuqhuba ukushisa zihlukile ezindaweni ezihlukene, amamaki ahlukene amaroli e-carbide kufanele asetshenziswe ezindaweni ezihlukene.Enqubweni yokuklama impahla ye-carbide roll, kuyadingeka ukuqinisekisa ukufanelana okunengqondo kwamandla, ubulukhuni kanye nokuqina komthelela wama-roll, kanye nedathabhesi yemingcele yezakhiwo ezishisayo zamamaki e-alloy ahlukene wezinto zokwakha kufanele kusungulwe ukuze kuqashwe ukwenziwa kahle kwempahla ye-roll. ukuklama ngokusebenzisa ikhompuyutha.
(4) Ngenxa yenqubo yokugoqa, ukugqoka kwe-carbide roll akuthintwa nje kuphela izimo zangaphandle ezifana nezinga lokushisa, ingcindezi eginqikayo kanye nomthwalo wokushisa oshisayo, kodwa futhi nezici zangaphakathi ezifana nokuba khona kokusabela okuyinkimbinkimbi kwe-physicochemical phakathi kwesigaba esinzima se-WC kanye isigaba sokunamathela Co/Co-Ni-Cr.Lokhu kwenza isimo sokugqoka sibe nzima nakakhulu.Ngenxa yalesi sizathu, kuyadingeka ukuqinisa ucwaningo ngalesi sici somshini.
