25CrMo4 ingxubevange yensimbi iyi-ainsimbi ephansi ye-alloy structuralimpahla, okuyingxenye Cr-Mo uchungechunge ingxubevange steel structural. Ngokusebenzisaukwelashwa ukushisainqubo, ukwakheka nokusebenza kwalesi sici kungalawulwa ngokuphawulekayo, ngamandla amakhulu nobulukhuni, kanye nokumelana nokugqoka okuhle nokumelana nokugqwala. Izakhiwo zayo eziphakeme zemishini nokumelana nokushisa kuyenza isetshenziswe kabanzi emikhakheni ehlukahlukene yobunjiniyela, ikakhulukazi ezikhathini ezidinga amandla aphezulu kanye nokumelana nokushisa okuphezulu.Ukutshala imaliingenye yezindlela ezivamile zokukhiqiza izingxenye ezinembayo ezinjalo.
Izici Ezibalulekile
1.Ukwakheka Kwamakhemikhali
Ukwakheka kwamakhemikhali kwe-25CrMo4 alloy steel ikakhulukazi kufaka i-chromium ne-molybdenum, edlala indima ebalulekile ekuthuthukiseni amandla nokuqina kwento. Ukwengezwa kwe-chromium kuthuthukisa ukumelana nokugqwala nobulukhuni bento, kuyilapho i-molybdenum ithuthukisa amandla okushisa aphezulu kanye nokumelana nokukhathala. Ngaphezu kwalokho, okuqukethwe kwekhabhoni ne-manganese kuphinde kwakhiwe kahle ukuze kuthuthukiswe ukushisela kanye nokusebenza kahle, ukuze okokusebenza kusebenze kahle ngaphansi kwezimo zokusebenza ezinzima.
2. Izakhiwo Zemishini
Izinto ezisetshenziswayo zinamandla amahle kakhulu okuqina namandla okukhiqiza, zingakwazi ukumelana nemithwalo esindayo namandla omthelela, futhi ziqinisekisa ukuzinza nokuphepha kwesakhiwo ngaphansi kwezimo zomthwalo ophezulu. Ukumelana kwayo nokugqoka kuvumela inhloko engaguquki ukuthi igcine impilo enhle yesevisi endaweni enokugqoka njalo, ukunciphisa imvamisa yokugcinwa nokushintshwa, ngaleyo ndlela ithuthukise ukusebenza kahle komsebenzi jikelele.
3. Ukusebenza Kokwelashwa Kokushisa
Ukusebenza kwensimbi ye-alloy engu-25CrMo4 kungathuthukiswa kakhulu ngezinqubo zokwelapha ukushisa njengokujwayelekile, ukucisha kanye nokushisa. Lezi zinqubo zingalungisa i-microstructure yezinto ezibonakalayo ukuze ikwazi ukugcina ipulasitiki enhle nokuqina ngenkathi ithuthukisa amandla, ivumelane nezimo zokusebenza ezahlukene kanye nezidingo zohlelo lokusebenza. Ngokuya ngendawo ethile yokusetshenziswa, imingcele yokwelapha ukushisa ingalawulwa ngokunembile ukuze kuqinisekiswe ukuthi inhloko ngayinye yokukhweza yenza kahle kakhulu ekusetshenzisweni kwayo okuqondile.

Izicelo Zokulungisa Ozimele
1. Imishini kagesi:
Emishinini yemishini, amakhanda anjalo angaguquki angasetshenziswa ukuxhuma ama-drive shafts, ama-levers noma ezinye izingxenye ezidinga ukuxhunywa ngokuqinile. Ingaqinisekisa ukuthi lezi zingxenye zihlala zixhumene ngokuzinzile lapho zigijima ngesivinini esikhulu noma ngaphansi kwengcindezi enkulu.
2. Izinto zasendlini:
Kumishini yokuhlanza ivacuum, imishini yokuwasha noma ezinye izinto zasendlini, amakhanda anjalo angashintshi angasetshenziswa njengezinto zangaphakathi, njengamapayipi axhumayo, ama-motor shafts noma ezinye izingxenye ezibalulekile. Isakhiwo sayo esiqinile kanye nomklamo okulula ukuwuxhuma kwenza ukugcinwa nokushintshwa kwezingxenye kube lula.
3. Amathuluzi ezimboni:
Ezindaweni zokusebenzela noma ezimbonini, amakhanda anjalo angaguquki angasetshenziswa njengezingxenye zamathuluzi kagesi, amathuluzi ezandla noma izinsimbi. Zisiza ukugcina ukuzinza kwamathuluzi futhi zithuthukise ukusebenza kahle nokuphepha.
4.Izingxenye ezizenzakalelayo:
Emkhakheni wokukhiqiza noma wokulungisa izimoto, amakhanda angashintshi angasetshenziswa ukuxhuma noma ukulungisa izingxenye zemoto, njengezingxenye zenjini, amasistimu amisiwe noma amasistimu amabhuleki. Ukuqina nokuthembeka kwayo kubalulekile ukuze kuqinisekiswe ukusebenza nokuphepha kwemoto.
