Insimbi ye-alloy

Insimbi ye-alloy
Ukuhlukaniswa kwensimbi ye-alloy
Ngokusho kokuqukethwe kwe-alloy element
Insimbi ye-Alloy ephansi (i-alloy ephelele ingaphansi kwama-5%), i-medium alloy steel (Ingqikithi ye-alloy ingu-5% -10%), i-alloy ye-alloy ephezulu (i-alloy ephelele (i-alloy ephelele (i-alloy ephelele (i-alloy ephelele iphakeme kune-10%).
Ngokusho kokwakheka kwe-alloy element
I-Chromium Steel (CR-FE-C), i-Chromium-Nickel Steel (CR-NICKEL COSCE (CR-NE-FE-FECE (MN-FE-C), Silicon-Maninganese Steel (SI-MN-FE-C).
Ngokusho kwesibonelo esincane esijwayelekile noma sakhiwo
Insimbi yensimbi yensimbi, insimbi yomfelamutho, insimbi, insimbi ye-aucenite, i-ledebure yensimbi.
Ngokusho kokusetshenziswa
Insimbi ye-alloy ehlelekile, insimbi yamathuluzi alloy, insimbi ekhethekile yokusebenza.
Inani lensimbi ye-alloy
Okuqukethwe kwekhabhoni kukhonjiswa ngenombolo ekuqaleni kwebanga. Kuchazwe ukuthi okuqukethwe kwekhabhoni kuboniswa inombolo (amadijithi amabili) kumayunithi athile ayishumi ngensimbi yensimbi eyodwa nensimbi eyodwa (okuqukethwe okukodwa (okuqukethwe kwekhabhoni) aboniswa lapho okuqukethwe kwe-carbon kwensimbi yensimbi kudlula i-1%.
Ngemuva kokukhombisa okuqukethwe kwekhabhoni, uphawu lwamakhemikhali lwento lusetshenziselwa ukukhombisa into enkulu yokufaka insimbi. Okuqukethwe kukhonjiswa ngenombolo ngemuva kwayo. Lapho okuqukethwe okuphakathi kungaphansi kwe-1.5%, ayikho inombolo emakwe. Lapho okuqukethwe okuphakathi kungu-1.5% kuya ku-2.49%, ama-2,5% kuya ku-3.49%, njll., 2, 3, njll.
I-alloy ehlelekile yensimbi engu-40cr inokuqukethwe okumaphakathi kwekhabhoni okungu-0.40%, futhi okuqukethwe kwento enkulu ye-Alloying CR kungaphansi kwe-1.5%.
I-Alloy Tool Steel 5CrmNMO inokuqukethwe okumaphakathi kwekhabhoni okungu-0.5%, kanye nokuqukethwe kwezinto eziphambili ze-Alloy
Ama-special nsimbi amakwe ngama-Chinese Fielnetic Phonetity okusetshenziswa kwawo. Isibonelo: Insimbi enezinsimbi, imakwe nge "G" ngaphambi kwenombolo yensimbi. I-GCR15 ikhombisa insimbi enezinsimbi ngokuqukethwe kwekhabhoni ecishe ibe ngu-1.0% kanye nokuqukethwe kwe-chromium cishe ngo-1.5% (lokhu kuyicala elikhethekile, okuqukethwe kwe-chromium kuvezwa ngenhlanganisela yenkulungwane eyodwa). I-Y40MN ibonisa insimbi yokusika mahhala ngokuqukethwe kwekhabhoni engu-0.4% kanye nokuqukethwe kwe-manganese okungaphansi kwe-1.5%, njll. Ngensimbi ephezulu, "A" yengezwa ekugcineni kwensimbi ukukhombisa lokhu, njenge-20CR2NI4.
Ukwahlanganiswa kwensimbi
Ngemuva kokuthi izinto ezengeziwe ezengeziwe zengezwa ngensimbi, izingxenye eziyisisekelo zensimbi, i-iron nekhabhoni, zizosebenzisana nezinto ezengeziwe zokuqalisa. Inhloso yensimbi ethokozisayo ukuthuthukisa ukwakheka kanye nezakhiwo zensimbi ngokusebenzisa ukuxhumana phakathi kwezinto ezenziwayo nensimbi nekhabhoni kanye nethonya kumdwebo wesigaba se-iron-carbon kanye nokwelashwa kokushisa kwensimbi.
Ukuxhumana phakathi kwezinto ezenziwayo nensimbi nekhabhoni
Ngemuva kokuthi izinto ezengeziwe zengezwa ngensimbi, zikhona ngensimbi ikakhulukazi ngezindlela ezintathu. Okungukuthi: ukwakha ikhambi eliqinile ngensimbi; kwakha ama-carbusidis ngekhabhoni; nokwakha amakhompiyutha aphakathi nendawo ngensimbi ephezulu.

Insimbi ye-Alloy Ehlelekile
Insimbi esetshenziselwa ukukhiqiza izinhlaka zobunjiniyela ezibalulekile nezingxenye zomshini ibizwa nge-alloy ehlelekile. Kunensimbi ehlelekile kakhulu ye-alloy, i-alloy carbuling yensimbi, i-alley ecisiwe nensimbi yensimbi, nensimbi yentwasahlobo ye-alloy, nebhola elinensimbi.
Insimbi enobumba ephansi
1. Ukusetshenziswa okusetshenziswa kakhulu ekwenziweni kwamabhuloho, imikhumbi, izimoto, ama-boilers, imithambo yengcindezi ephezulu, amapayipi ensimbi kanye negesi, izakhiwo ezinkulu zensimbi, njll.
2. Izidingo Zokusebenza
(1) Amandla aphezulu: Ngokuvamile, amandla alo wokuthenga angaphezulu kwama-300mpa.
. Kwezakhi ezinkulu ezinama-welded, ubunzima bokuphuka obuphakeme buyadingeka futhi.
(3) Ukusebenza okuhle kwe-welding kanye nokusebenza okubandayo kwakha.
(4) izinga lokushisa eliphansi elibandayo.
(5) Ukumelana nokugqwala okuhle.
3. Izici zokwakheka
.
(2) Ukungeza izakhi ze-alloy ikakhulukazi ezakhiwa amangane.
.
Ngaphezu kwalokho, engeza inani elincane lethusi (≤0.4%) ne-phosphorus (cishe 0.1%) kungathuthukisa ukumelana nokugqwala. Ukungeza inani elincane lezinto zomhlaba ezingandile ezingasuswa kanye nama-degas, hlanza insimbi, futhi uthuthukise ukusebenza nokusebenza kwenqubo.
I-4
I-16mn iyinsimbi esetshenziswa kakhulu futhi ekhiqizwayo emandleni aphansi wezwe lami eliphakeme. Isakhiwo esisesisesimweni sakhiwe kahle uFerrite-Perrite, futhi amandla acishe abe ngu-20% aphakeme ku-30% aphezulu kunalokho kwensimbi evamile yekhabhoni ehlelekile ye-Q235, futhi ukumelana nokonakala komkhathi kungama-38% aphezulu.
I-15MNVN iyinsimbi esetshenziswa kakhulu kuma-medium-grade amandla insimbi. Inamandla aphezulu, nobulukhuni obuhle, ukusheshiswa kanye nokulimala okushisa okuphansi. Kusetshenziswa kabanzi ekwakheni izakhiwo ezinkulu ezifana namabhuloho, ama-boilers, nemikhumbi.
Lapho izinga lamandla lidlula ama-500MPA, izinhlaka ze-Ferrite ne-pearlite kunzima ukufeza izidingo, kwakhiwa insimbi ephansi ye-carbon baini. Ukungeza izinto ezinjenge-Cr, MO, MN, no-B kuyakuzuzisa ukuthola isakhiwo seBaini ngaphansi kwezimo zokuphola komoya, okwenza amandla aphakeme, futhi ukusebenza kweplastiki kanye nokusebenza kwe-welding nakho kungcono. Isetshenziswa kakhulu kuma-boilers acindezele kakhulu, iziqukathi zengcindezi ephezulu, njll.
5. Heat Ukwelashwa Izici
Lolu hlobo lwensimbi luvame ukusetshenziswa esimweni esiseduze somoya osongelwe futhi aludingi ukwelashwa okushisa okukhethekile. Isimo semvelo esisesimweni sokusebenzisa ngokuvamile kunguFerrite + neToostite.
