Kwinkqubo yokusebenza, isitya somhlathi sihlala sinxitywa, esichaphazela ukusebenza okuqhelekileyo kwesityuli somhlathi. Eli phepha liphonononga intsimbi ephantsi-khabhoni ingxubevange izinto isityumzi imihlathi, kwaye uxoxe umthetho utshintsho ipleyiti yomhlathi ubulukhuni kunye nokumelana banxibe, ukuze ukumisela ubushushu ukucima xa ipleyiti yomhlathi ukunxiba ukuxhathisa ifikelela kwinqanaba elungileyo.
Ukukhethwa kwezinto zomhlathi
1. Kwimveliso, ipleyiti yomhlathi eshukumayo kunye nepleyiti yomhlathi emiselweyo yenziwe ngentsimbi engagugiyo yemanganese ephezulu, eyona liner kunye ne-eccentric bearing liner yenziwe nge-cast babbitt alloy, kwaye ipleyiti yomhlathi yenziwe ngentsimbi etyhidiweyo ukuphucula umgangatho wayo. ukuqina. Ipleyiti yomhlathi wesityumsi somhlathi kufuneka ibe senkonzweni phantsi kweemeko zokungagugi, ukumelana nefuthe kunye nokuqina okuphezulu. Abavelisi abohlukeneyo basebenzisa izixhobo ezahlukeneyo zepleyiti yomhlathi, njengentsimbi ephezulu yemanganese, intsimbi ephakathi yemanganese, intsimbi egxothiweyo, intsimbi ephakathi kwekhabhoni ephantsi kwengxubevange yokunxiba kunye nentsimbi ephezulu yechromium.
2. I-Medium-carbon low-alloy wear-resistant steel ifumaneka ngokudibanisa izinto ezahlukeneyo ze-alloy ezifana ne-Cr, Si, Mn, Mo, V ngesiseko sensimbi ye-carbon, kunye ne-alloy content ingaphantsi kwe-5. %. Olu hlobo lwe-carbon low-alloy-alloy wear-resistant steel luyakwazi ukulungelelanisa ngokufanelekileyo umxholo wekhabhoni kunye nomxholo we-alloy element, ngoko unokudityaniswa neenkqubo ezahlukeneyo zonyango lobushushu ukufumana iimpawu ezahlukeneyo zoomatshini, ngoko kuye kwatsala ingqalelo ngakumbi kunye nokusetyenziswa. Kweli phepha, ukunyanzeliswa kokunxiba kwe-medium carbon low alloy ZG42Mn2Si1REB yafundwa, kwaye umthetho wokutshintsha ubulukhuni kunye nokumelana nokunxiba kunye nobushushu bokucima kwaxoxwa, kwaye inkqubo yonyango engcono yafunyanwa.
Tyena ukhetho inkqubo unyango ubushushu
Ngokweempawu zensimbi ye-ZG42Mn2Si1REB, isakhiwo se-martensite esifunyenwe emva kokucima sinobunzima obuphezulu kunye nokumelana nokunxiba okungcono. Amanqaku amathathu obushushu obungama-870℃, 900℃ kunye ne-930℃ akhethelwe unyango lobushushu, kwaye ubushushu bobushushu bulungiswe ngokulinganayo kwi-230℃. Ngenxa yokuba izinto eziphathekayo aziqukethe i-Mo element, ukwenzela ukuba kuqinisekiswe ukuqina, isisombululo se-5% se-Nacl sisetyenziselwa ukupholisa.
Iziphumo kunye nohlalutyo
1. Impembelelo yokucima ukushisa kubunzima kunye nokumelana nokugqoka
Ukuqina kweesampulu ezicinywe kumaqondo obushushu ahlukeneyo kwalinganiswa ngemitha yobunzima be-HR-150A Rockwell, ukulinganisa amanqaku ama-5 ngexesha ngalinye kwaye emva koko kuthatha ixabiso eliphakathi. Kwafunyaniswa ukuba ngokunyuka kobushushu bokucima, ukuqina kokucima kuqala kwanda kwaye kwanciphisa. Xa ubushushu bokucima bungama-870℃, ukuqina yi-HRC53. Xa ubushushu bokucima bunyuka ukuya kuma-900℃, ukuqina kwakhona kuyenyuka ukuya kwi-HRC55. Ingabonwa ukuba ubunzima buyanda ngokunyuka kweqondo lokushisa; Xa iqondo lobushushu liqhubeka nokunyuka ukuya kuma-930℃, ubulukhuni buyehla ukuya kwi-HRC54, kwaye kunokufunyaniswa ukuba ukuqina kuphezulu xa kucinywa ku-900℃. Ngoko ke, ngokunyuka kweqondo lokushisa, ukulahlekelwa kwesisindo sokugqoka kuncipha. Xa ubushushu buqhubeka nokunyuka ukuya kuma-930 ℃, ukwehla kobunzima bomzimba kuyanda ukuya kwi-3.5mg. Inokubonwa ukuba xa icinywa kwi-900 ℃, ubulukhuni bayo buphezulu kwaye ukulahlekelwa kwesisindo somzimba kungabikho. I-carbon low-alloy i-alloy ephakathi inxiba-resistant steel ZG42Mn2Si1REB inokumelana nokunxiba kakuhle, nto leyo ebonisa ukuba inkqubo ngeli xesha yinkqubo echanekileyo yonyango lobushushu.
2. Ukuthelekiswa kokuxhatshazwa kokugqoka phakathi kwe-carbon low alloy kunye nentsimbi ephezulu ye-manganese
Ukubonisa ukuxhathisa okuphezulu kwentsimbi ye-carbon alloy steel ZG42Mn2Si1REB, le nto ithelekiswa nentsimbi ye-manganese ephezulu ye-ZGMn13. Phakathi kwazo, i-ZG42Mn2Si1REB yavavanywa ngokwemiqathango yetekhnoloji ekhankanywe ngasentla yokucima kwi-900 ℃ kunye nokutshisa kwi-230 ℃, kunye nentsimbi ephezulu ye-manganese i-ZGMn13 iphathwe ngokuqinisa amanzi. Iziphumo zovavanyo zibonisa ukuba ukuxhathisa banxibe yangaphambili 1.5 amaxesha le yokugqibela, nto leyo ebonisa ukuba ipleyiti emhlathini medium carbon ephantsi ingxubevange yentsimbi uye wasebenzisa ngokupheleleyo amandla ezinto eziphathekayo kunye nokumelana egqwesileyo banxibe phantsi kweemeko ezifanelekileyo unyango ubushushu.
Ngokubhekiselele kwixabiso lezinto eziphathekayo, insimbi ephezulu ye-manganese iqulethe ukuya kwi-13% ye-Mn, ngoko kufuneka idle izinto ezininzi ze-alloy. Xa kuthelekiswa nentsimbi ephezulu ye-manganese, i-medium carbon low alloy steel ZG42Mn2Si1REB iqulethe kuphela i-3% ~ 4% ye-alloy elements, kwaye ayinayo i-Cr kunye ne-Mo elements, ngoko inexabiso eliphezulu lokukhuphisana. Ukongeza, xa kuqwalaselwa inkqubo yonyango lobushushu, intsimbi ephakathi kwekhabhoni ephantsi ialloy icinywa kwi-900 ℃ kwaye ipholile kwi-230 ℃, ngelixa unyango olucokisekileyo lwamanzi lwentsimbi ephezulu ye-manganese luhlala ludlula i-1000 ℃, ngoko ke ubushushu bokucinywa kweyokuqala buphantsi, ixesha lokufudumala lifutshane, kwaye umphumo wokonga amandla uphawuleka ngakumbi. Inkqubo yonyango yokushisa engcono yasetyenziswa kwipleyiti yomhlathi we-crusher, ephucula ngokucacileyo ukuxhathisa ukunxiba, kwaye umjikelo wokutshintshwa kwepleyiti yomhlathi wandiswa ukusuka kwi-150d ukuya kwi-225d, kunye neenzuzo ezicacileyo zoqoqosho.
Ngophando malunga nokumelana nokunxitywa kwepleyiti yomhlathi yentsimbi ephakathi kwekhabhoni ephantsi yentsimbi yesityutyu somhlathi, iziphumo zibonisa ukuba xa zicinywa kwi-900 ℃, i-microstructure emva kokucima i-martensite, ngeli xesha, ubunzima buphezulu, ubunzima bokunxiba. ilahleko iphantsi, kwaye ukumelana nokunxiba kungcono.
