I-lining plate iyingxenye eyinhloko ye-i-crusher, kodwa futhi ingxenye egqokwa kakhulu. Insimbi ye-manganese ephezulu njengensimbi evame ukusetshenziswa, ngenxa yomthelela wayo oqinile noma ukuthintana namandla angaphandle lapho ubuso buzoqina ngokushesha, futhi umnyombo usagcina ukuqina okuqinile, lokhu kuqina kwangaphandle okuqinile nokuqina kwangaphakathi kokubili ukugqoka kanye nomthelela wokumelana nezici ukumelana nomthelela onamandla, ukucindezela okukhulu, ukumelana nokugqoka kwawo akufani nezinye izinto. Lapha ukukhuluma ngomthelela wezakhi eziyinhloko ze-alloying kuzakhiwo zensimbi ye-manganese ephezulu.
1, lapho i-carbon element iphonswa, ngokwanda kokuqukethwe kwekhabhoni, amandla nobulukhuni bensimbi ephezulu ye-manganese kuthuthukiswa ngokuqhubekayo phakathi kwebanga elithile, kodwa i-plasticity nokuqina kuyancipha kakhulu. Lapho okuqukethwe kwekhabhoni kufinyelela cishe ku-1.3%, ukuqina kwensimbi ye-as-cast kuncipha ku-zero. Ikakhulukazi, okuqukethwe kwekhabhoni yensimbi ephezulu ye-manganese esebenza ngaphansi kwezimo eziphansi zokushisa kubaluleke kakhulu, okuqukethwe kwekhabhoni okungu-1.06% no-1.48% kwezinhlobo ezimbili zensimbi njengesiqhathaniso, umehluko wokuqina komthelela phakathi kwakho kokubili cishe izikhathi ezingu-2.6 ku-20 ℃, futhi umehluko cishe izikhathi ezingu-5.3 ku -40 ℃.
Ngaphansi kwesimo somthelela ongenamandla, ukumelana nokugqokwa kwensimbi ephezulu ye-manganese kuyanda ngokwanda kokuqukethwe kwekhabhoni, ngoba ukuqinisa isisombululo esiqinile sekhabhoni kunganciphisa ukuguga kwensimbi. Ngaphansi kwezimo eziqinile zomthelela, ngokuvamile kuthenjwa ukunciphisa okuqukethwe kwekhabhoni, futhi isakhiwo se-austenitic sesigaba esisodwa singatholakala ngokwelashwa okushisa, okune-plasticity enhle nokuqina futhi kulula ukuqinisa ngesikhathi senqubo yokubunjwa.
Kodwa-ke, ukukhetha okuqukethwe kwekhabhoni kuyinhlanganisela yezimo zokusebenza, ukwakheka kwengcezu yokusebenza, izindlela zenqubo yokuphonsa kanye nezinye izidingo zokugwema ukwanda ngokungaboni noma ukunciphisa okuqukethwe kwekhabhoni. Isibonelo, ngenxa yesivinini sokupholisa esinensayo sokukhonjiswa ngezindonga eziwugqinsi, kufanele kukhethwe okuqukethwe kwekhabhoni ephansi, okunganciphisa umthelela wemvula yekhabhoni enhlanganweni. Ukulingisa okunezindonga ezincane kungakhethwa ngokufanelekile ngokuqukethwe kwekhabhoni ephezulu. Izinga lokupholisa lokulingwa kwesihlabathi lihamba kancane kunelo lokusakaza kwensimbi, futhi okuqukethwe kwekhabhoni kokulingisa kungaba phansi ngokufanelekile. Lapho ingcindezi ecindezelayo yensimbi ephezulu ye-manganese incane futhi ubulukhuni bezinto ezibonakalayo buphansi, okuqukethwe kwekhabhoni kungakhuliswa ngokufanelekile.
2, i-manganese manganese iyisici esiyinhloko se-austenite ezinzile, i-carbon ne-manganese ingathuthukisa ukuzinza kwe-austenite. Uma okuqukethwe kwekhabhoni kungashintshiwe, ukwanda kokuqukethwe kwe-manganese kulungele ukuguqulwa kwesakhiwo sensimbi sibe yi-austenite. I-Manganese iyancibilika ku-austenite ngensimbi, engaqinisa isakhiwo se-matrix. Lapho okuqukethwe kwe-manganese kungaphansi kuka-14%, amandla kanye nepulasitiki kuzothuthukiswa ngokwanda kokuqukethwe kwe-manganese, kodwa i-manganese ayikukhuthazi ukusebenza kanzima, futhi ukwanda kokuqukethwe kwe-manganese kuzolimaza ukumelana nokugqoka, ngakho-ke okuqukethwe okuphezulu i-manganese ayikwazi ukulandelwa ngobumpumputhe.
3, ezinye izakhi ze-silicon kububanzi obujwayelekile bokuqukethwe idlala indima eyisizayo ekukhishweni kwe-oxidation, ngaphansi kwezimo zomthelela ophansi, ukwanda kokuqukethwe kwe-silicon kulungele ukuthuthukisa ukumelana nokugqokwa. Uma okuqukethwe kwe-silicon kungaphezu kuka-0.65%, ukuthambekela kwensimbi ukuqhekeka kuyaqina, futhi ngokuvamile kuyafiswa ukulawula okuqukethwe kwe-silicon ngaphansi kuka-0.6%.
Ukwengeza i-chromium engu-1% -2% ensimbi ephezulu ye-manganese isetshenziselwa ukwenza amazinyo ebhakede ezimba kanye ne-lining plate ye-cone crusher, okungathuthukisa kakhulu ukumelana nokuguga kwemikhiqizo futhi kunwebe impilo yesevisi. Ngaphansi kwezimo ezifanayo zokuguquguquka, inani lokuqina lensimbi ye-manganese equkethe i-chromium liphakeme kunelensimbi engena-chromium. I-Nickel ayithinti ukusebenza kokuqina komsebenzi kanye nokumelana nokugqoka kwensimbi, ngakho-ke ukumelana nokugqoka akukwazi ukuthuthukiswa ngokungeza i-nickel, kodwa ukuthi i-nickel nezinye izinsimbi ezifana ne-chromium zengezwa kanjani ensimbi ngesikhathi esifanayo zingathuthukisa ubulukhuni obuyisisekelo bensimbi. , futhi kuthuthukiswe ukumelana nokugqokwa ngaphansi kwezimo zokugqokwa kwe-abrasive okungenamandla.
Izakhi zomhlaba ezingavamile zingathuthukisa ukuqina kongqimba oluguquguqukayo lwensimbi ephezulu ye-manganese, zithuthukise ikhono lokubopha ungqimba oluqinile nge-matrix engaphansi, futhi zinciphise amathuba okuphuka kongqimba oluqinile ngaphansi komthwalo womthelela, okuzuzisa ukuthuthukisa umthelela. ukumelana nokugqoka kwensimbi ephezulu ye-manganese. Inhlanganisela yezakhi zomhlaba ezingavamile kanye nezinye izakhi ze-alloying ngokuvamile zithola imiphumela emihle.
Iyiphi inhlanganisela yezakhi eyisinqumo esingcono kakhulu? Izimo zokuxhumana nengcindezi ephezulu kanye nezimo eziphansi zengcindezi zihambisana nezinhlanganisela ezijwayelekile zezinto ezahlukahlukene, ukuze kudlale umsebenzi oqinisayo nokumelana nokugqoka kwensimbi ephezulu ye-manganese.
