Ipuleti lensimbi

Yinsimbi eyisicaba ephonswa ngensimbi ebilisiwe futhi icindezelwe ngemuva kokupholisa.
Kuyinto eyisicaba, exande futhi ingagibela ngqo noma inqunywe emithini ebanzi yensimbi.
Ipuleti lensimbi lihlukaniswe ngokuya ngobukhulu, ipuleti lensimbi elincanyana lingaphansi kuka-4 mm (the Thinnest lingu-0.2 mm), ipuleti lensimbi eliphakathi nendawo lingu-4-60 mm, bese ipuleti lensimbi elingaphezulu lingu-60-115 mm.
Amashidi ensimbi ahlukaniswe ngokugoqwa okushisayo futhi okubandayo okugoqiwe ngokuya ngokugingqa.
Ububanzi bepuleti elincanyana bungama-500 ~ 1500 mm; Ububanzi beshidi elibukhali bungama-600 ~ 3000 mm. Amashidi ahlukaniswe ngohlobo lwensimbi, kufaka phakathi insimbi ejwayelekile, i-arloy yensimbi, insimbi ye-alloy, insimbi engagqwali, insimbi yokushisa, insimbi yensimbi yensimbi, i-silicon pure iron sheet, njll.; Iplateli ye-Enamel, ipuleti le-bulletproof, njll. Ngokuya ngenhlanganisela engaphezulu, kukhona ishidi eligayiwe, ishidi elinezitezi ze-tin, ishidi eliholayo, ishidi lensimbi eliyinhlanganisela, njll.
Insimbi ephansi ye-alloy ephansi
(eyaziwa nangokuthi i-alloy evamile ephansi, HSLA)
1. Inhloso
Isetshenziswa ikakhulukazi ekwenziweni kwamabhuloho, imikhumbi, izimoto, ama-boilers, imithambo yengcindezi ephezulu, amapayipi kawoyela negesi, izakhiwo ezinkulu zensimbi, njll.
2. Izidingo Zokusebenza
(1) Amandla aphezulu: Ngokuvamile amandla alo wokuthenga angaphezulu kwama-300MPA.
. Ezingxenyeni ezinkulu ezinama-welded, ubunzima obukhulu buyadingeka.
(3) Ukusebenza okuhle kwe-welding kanye nokusebenza okubandayo kwakha.
(4) izinga lokushisa eliphansi elibandayo.
(5) Ukumelana nokugqwala okuhle.
3. Izici Zokungena
.
(2) Faka izinto ezenziwa ngabangane ezisuselwa eManganese.
.
Ngaphezu kwalokho, engeza inani elincane lethusi (≤0.4%) ne-phosphorus (cishe nge-0.1%) kungathuthukisa ukumelana nokukhulisa. Ukungeza inani elincane lezinto zomhlaba ezingandile ezingahle zisuse kanye nama-degas, zihlanze insimbi, futhi zithuthukise ukusebenza nokusebenza kwenqubo.
4. I-alloy ejwayelekile esetshenziswayo
I-16MN uhlelo olusetshenziswa kakhulu nolukhiqizayo kakhulu lwensimbi ephansi yamandla aphezulu ezweni lami. Isakhiwo esisesisetshenzisiwe se-Perrite se-Ferrite-pearlite, namandla aso acishe abe ngu-20% kuya ku-30% aphezulu kunalokho kwensimbi evamile yekhabhoni ehlelekile ye-Q235, futhi ukumelana kwalo kokonakala komkhathi kuya kuma-20% aphezulu.
I-15MNVN iyinsimbi esetshenziswa kakhulu kuma-liment-a manzi. Inamandla aphezulu, nobulukhuni obuhle, ukufudumala kanye nokuqina okushisa okuphansi, futhi kusetshenziswa kabanzi ekwakheni izakhiwo ezinkulu ezifana namabhuloho, amabhulukwe, nemikhumbi.
Ngemuva kokuthi izinga lamandla lidlula ama-500MPA, izinhlaka ze-Ferrite ne-Pearlite zinzima ukufeza izidingo, kuthuthukiswa kakhulu i-Carbon Baintic Steel. Ukungezelelwa kwe-CR, MN, B nezinye izinto ezizuzisayo ukuthola isakhiwo seBaini ngaphansi kwezimo zokuphola komoya, ukuze amandla aphezulu aphezulu, futhi asetshenziswa kakhulu kuma-boilers aphezulu wengcindezi , imithambo ephezulu yengcindezi, njll.
5. Izici zokwelashwa kokushisa
Lolu hlobo lwensimbi ngokuvamile lusetshenziswa esimweni esisehlathini esishisayo nolupholile somoya futhi aludingi ukwelashwa okuphezulu kokushisa. I-MicroSCRUCTUCTURE ESESETYENZISWA KOKUSETYENZISWA KAKHULU KAKHULU KAKHULU + SORBITE.
Insimbi ephathekayo ye-alloy
1. Inhloso
Isetshenziswa ikakhulukazi ekwakheni amagiya okuhambisa ezimotweni nasezimotweni, ama-camshaff, ama-piston pins kanye nezinye izingxenye zomshini ezinjini zokuhlangana zangaphakathi. Izingxenye ezinjalo zihlushwa ukungqubuzana okuqinile nokugqoka ngesikhathi somsebenzi, futhi ngasikhathi sinye zithwala imithwalo enkulu yokushintshana, ikakhulukazi imithwalo emibi.
2. Izidingo Zokusebenza
.
(2) Umgogodla unobutha obuphezulu kanye namandla aphezulu ngokwanele. Lapho ubunzima bomongo bunganele, kulula ukugqashula ngaphansi kwesenzo somthwalo womthelela noma umthwalo omkhulu; Lapho amandla anganele, ungqimba oluhlanganisiwe lwe-brittle luphulwe kalula futhi luhluthwe.

4. Ibanga lensimbi nebanga
I-20cr hardiability yensimbi ehlanganisiwe ye-alloy. Lolu hlobo lwensimbi lunokuqina okuphansi kanye namandla aphansi aphansi.
I-20Crmnti Hartenumability ye-alloy ehlanganisiwe. Lolu hlobo lwensimbi lunokuqina okuphezulu, ukuzwela okuthe xaxa okuphezulu ngokweqile, ungqimba olungafani lokulinganisa, kanye nezinto ezinhle zemishini nezobuchwepheshe.
I-18cr2ni4wa kanye ne-20CR2NI4A ephezulu i-Harterability yensimbi ethambile. Lolu hlobo lwensimbi luqukethe izinto eziningi ezifana ne-CR ne-NI, kunokuqina okuphezulu, futhi kunobunzima obuhle nobunzima bokushisa okushisa okuphansi.
I-5. Ukwelashwa kokushisa kanye nezakhiwo ezedlule
Inqubo yokwelashwa yokushisa yensimbi ephathekayo ye-alloy ngokuvamile iconsa ngokuqondile ngemuva kokuzikhandla, bese kufutheka emazingeni okushisa aphansi. Ngemuva kokwelashwa okushisa, ukwakheka kwesendlalelo se-cartised ebunjiwe yi-allensite + enomfeyimuko omncane + nenani elincane le-auStenite egciniwe, futhi ubunzima bungu-60hrc ~ 62hrc. Isakhiwo esiyisisekelo sihlobene nokuqina kwensimbi kanye nosayizi wesigaba sesigaba sezingxenye. Lapho qina ngokugcwele, i-carbon enomfutho ephansi enokwakhiwa kobulukhuni be-40hrc kuya ku-48hrc; Ezimweni eziningi, kungubuchwepheshe, othukuthele kanye nenani elincane lensimbi. Umzimba we-Ement, Ubulukhuni ngu-25hrc ~ 40hrc. Ubulukhuni benhliziyo ngokuvamile buphakeme kune-700kj / m2.
I-alloy yacishwa futhi inensimbi
1. Inhloso
Insimbi ecijile futhi enesithukuthezi isetshenziswa kabanzi ekwakheni izingxenye ezahlukahlukene ezibalulekile ezimotweni, ogandaganda, amathuluzi omshini neminye imishini, ama-shaft, izinduku zokuxhuma, ama-bolts, njll.
2. Izidingo Zokusebenza
Iningi lezingxenye ezicijisiwe nezinomoya elinezinciko ezisebenzayo, isimo sengcindezi siyinkimbinkimbi, futhi izakhiwo eziphakeme zemishini ziyadingeka, okungukuthi, amandla aphezulu kanye nokuqina okuhle nokuqina. Insimbi ecijile nensimbi enomsindo nayo idinga ukuqina okuhle. Kodwa-ke, izimo zengcindezi zezingxenye ezahlukene zihlukile, futhi izidingo zokuqina zihlukile.
3. Izici Zokungena
(1) Ikhabhoni ephakathi nendawo: Okuqukethwe kwekhabhoni ngokuvamile kuphakathi kuka-0.25% no-0.50%, ngo-0.4% iningi;
. Isibonelo, ukusebenza kwensimbi engu-40cr ngemuva kokuqeda ukwelashwa nokugunda kuphakeme kakhulu kunaleyo yensimbi engu-45;
. Ukungezwa kwe-MO ne-W ngensimbi kungavimba uhlobo lwesibili lokuvutha ubucwebe, futhi okuqukethwe kwalo okufanele kucishe kube ngu-0.15% -0.30% mo noma 0.8% -1.2% W.
Ukuqhathaniswa kwezakhiwo zensimbi engu-45 nensimbi engu-40cr ngemuva kokucimana nokugunda
I-Steel Light kanye ne-Heat Treatment State State Isigaba Usayizi / MM SB / MPA SS / MPA SS / MPA D5 /% Y /% AK / KJ / M2

4. Ibanga lensimbi nebanga
.
. Ukungezwa kwe-molybdenum akunakuthuthukisa ukuqina, kepha futhi kuvimbela uhlobo lwesibili lokukhanya.
. Ukungeza i-molybdenum efanelekile ku-chromium-nickel yensimbi hhayi kuphela ukuqina okuhle, kepha futhi kuqeda uhlobo lwesibili lokukhanya komoya.
I-5. Ukwelashwa kokushisa kanye nezakhiwo ezedlule
Ukwelashwa kokugcina kokushisa kwensimbi ecijile nensimbi enomoya okuvuthayo kuyacishwa futhi ukulangazelela okuphezulu okushisa okuphezulu (ukujuluka nokugunda). Insimbi ecijile futhi enesithukuthezi inokuqina okuphezulu, futhi uwoyela usetshenziswa ngokuvamile. Lapho i-hardimability ikhulu ikakhulukazi, ingahle ibe nomoya, okunganciphisa ukulimala kokwelashwa okushisa.
Izakhiwo zokugcina zensimbi ecinwe futhi ezicijile zincike emazingeni okushisa anolaka. Ngokuvamile, ukufutheka ngo-500 ℃ -650 ℃ kuyasetshenziswa. Ngokukhetha amazinga okushisa anolaka, izakhiwo ezidingekayo zingatholakala. Ukuze uvikele uhlobo lwesibili lokuvutha ubucwebe, ukupholisa okusheshayo (ukupholisa kwamanzi noma ukupholisa kwamafutha) ngemuva kokushisa kuzuzisa ukuthuthuka kobunzima.
I-microsructure yensimbi ecijile neyothuthukiswa ngemuva kokuphathwa kokushisa okujwayelekile kunesifo somoya. Ezingxenyeni ezidinga indawo engamelana nokugula (njengamagiya nama-spindle), ukufudumeza kokushisa komhlaba okususwayo kanye nokushisa okushisa okuphansi kwenziwa, kanti nokwelashwa okushisa okuphansi kwenziwa, futhi kwakhiwa ukwakheka komhlaba. Ubulukhuni bendawo bungafinyelela ku-55hrc ~ 58hrc.
Amandla okuvutha wensimbi ecijile futhi enesithukuthezi ngemuva kokucimana nokuguga acishe abe ngu-800MPA, futhi ukuqina kwethonya kungu-800kj / kanye nobulukhuni bomgogodla ongafinyelela ku-22hrc ~ 25hrc. Uma usayizi wesigaba sesigaba mkhulu hhayi lukhuni, ukusebenza kuncishiswa kakhulu.
