Incamake: Aka gatabo gakubiyemo ibyuma bya QT400-18 ferritic ductile fer, GB / T 1348 igaragara, ibingana n’amahanga, indangagaciro za mashini, ibyiza, imbogamizi, porogaramu hamwe n’inoti za CNC.
QT400-18 nicyiciro cya ferritic ductile icyuma gisobanurwa kuri GB / T 1348.
Igaragaza ihindagurika ryinshi, ubukonje buke bwo hasi no gukomera, bikoreshwa cyane mubice bitarwanya ingaruka.
QT400-18 Niki?
QT400-18 ni spheroidal grafite yerekana ibyuma byagenwe nubushinwa GB / T 1348.
Sisitemu yo kwita izina ikurikiza amasezerano asanzwe yubushinwa bwimyanya yicyuma: "QT" isobanura spheroidal graphite cast fer; 400 bivuga imbaraga ntoya ya 400 MPa; na 18 byerekana igipimo ntarengwa cyo kuramba cya 18%.
Microstructure yayo yiganjemo ferrite, itanga ibikoresho umukono wacyo uhindagurika kandi ukora cyane.
Kugirango utangire byuzuye kubyuma byibanze, inzira yumusaruro hamwe nibyiciro rusange, urashobora gusuzuma ibyacu icyerekezo cyuzuye cyicyuma.
Iyi ngingo izibanda cyane cyane kuri QT400-18 kandi irinde gusubiramo ibintu rusange byuma byuma byuma.
QT400-18 Ibipimo & Bingana Impamyabumenyi Mpuzamahanga
GB / T 1348 Ibisobanuro bya QT400-18
QT400-18 igengwa na GB / T 1348, igipimo cyigihugu kuri spheroidal grafite castine icyuma mubushinwa.
Igenzura ryakirwa kuri iki cyiciro ahanini rishingiye kumikorere yubukanishi aho kuba imiti ihamye.
Impinduka zahinduwe, QT400-18L, nazo zisobanuwe muriki gipimo kugirango zuzuze ibisabwa ubushyuhe buke.
Ibikoresho bihwanye nisi yose (ASTM / EN / ISO)
Ba injeniyeri bakora kumashusho yambukiranya imipaka akenshi bakeneye gushushanya QT400-18 kumanota mpuzamahanga amenyereye.
Ibyinshi byemewe bihwanye kurutonde hepfo kugirango bikoreshwe gusa.
Kwemera ibikoresho byanyuma bigomba guhora bikurikiza amabwiriza agenga umushinga.
- ASTM A536: 60-40-18
- EN 1563: EN-GJS-400-18, izwi kandi nka GGG40 mubisobanuro bya DIN bishaje
QT400-18L nuburyo bwo hasi yubushyuhe bwasobanuwe muri GB / T 1348.
Ntishobora gusimburwa mu buryo butaziguye na QT400-18 cyangwa ibisanzwe bihwanye n’amahanga hatabanje gusubirwamo ibishushanyo mbonera.
QT400-18 Ibikoresho bya mehaniki & umubiri
Imbonerahamwe yimikorere
Indangagaciro zikoreshwa kuri QT400-18 zipimishwa kubisanzwe bipimisha.
Igikorwa nyacyo gishobora guhinduka ukurikije uburebure bwurukuta, igipimo cyo gukonjesha no kugenzura ibikorwa.

Ibyiza byingenzi & Imipaka ya QT400-18
Inyungu Zibanze
QT400-18 igaragara cyane mubyiciro bya ferritic ductile ibyuma kugirango ikomere kandi ikore.
- Kurambura cyane no guhindagurika, ubushobozi bukomeye bwo gukuramo imbaraga zingirakamaro
- Kwizerwa kwubushyuhe buke ugereranije na pearlitic ductile ibyuma
- Imashini nziza cyane yo guhindura CNC, gusya no kurambirana
- Ubushobozi bwiza bwo kunyeganyega bwo kuzunguruka nibikoresho bya hydraulic
- Guciriritse giciriritse kubintu bigoye, byoroheje-biciriritse kurukuta
Imipaka & Ibikwiye
QT400-18 ntabwo aricyuma cyumubyimba rusange, kandi abashushanya bagomba kwirinda kubishyira hejuru y ibahasha yimikorere.
- Ubukonje buke butuma uhitamo nabi kubice munsi yimyambarire ikabije
- Ntabwo bisabwa kubisabwa bisaba kwihanganira umunaniro mwinshi
- Ubunini bwurukuta bugira ingaruka zikomeye kuri ferrite; ibice binini birashobora gutakaza kuramba byemewe no gukomera
- Gusudira birashoboka ariko bisaba ubushyuhe bukabije na nyuma yubushyuhe kugirango wirinde gucika
QT400-18 Porogaramu Zisanzwe Zinganda
QT400-18 yatoranijwe mugihe kurwanya ingaruka no guhindagurika bifata umwanya munini kuruta imbaraga nyinshi cyangwa gukomera.
Bikunze gusobanurwa kubice bigira umutwaro wo guhungabana, kunyeganyega cyangwa kurenza urugero. Wige byinshi kubyacu ibyuma byubaka ibyuma.
Imanza zisanzwe zikoreshwa zirimo:
QT400-18 Gutanga & CNC Inyandiko
Ibitekerezo Byashingiweho kuri QT400-18
Matrix ihoraho ni intego yibanze yibikorwa bya QT400-18.
Amakipe yashinze yibanze ku ntambwe ebyiri zikomeye zo kugenzura: kuvura nodularisation no gutera.
Gutera neza birinda ubukonje kandi bigahindura imiterere ya grafite spheroid.
Shrinkage porosity na microshrinkage ni inenge zisanzwe za ferritic ductile fer.
Sisitemu yo kwinjirira hamwe na riser igomba gutegurwa kugirango iteze imbere icyerekezo, cyane cyane kubice biremereye.
Gukonjesha bidakwiye bizana pearlite kandi bigabanye kuramba munsi ya 18%.
Inama za CNC
Microstructure yoroshye ya ferritic ya QT400-18 itanga imikorere ihamye.
Irema ibyuma bikomeza aho kuba umukungugu utera, bigabanya kwambara ibikoresho ugereranije nicyuma gikomeye cya pearlitis.
- Carbide idashyizwemo ikora neza kugirango ihindurwe muri rusange
- Umuvuduko wo gutema urashobora gushyirwaho murwego rwo hejuru kurenza icyuma cyuma
- Ubuvuzi bwo hejuru nko gusiga amarangi, gutwika ifu cyangwa gutera amavuta bikoreshwa cyane mukurinda ruswa nyuma yo kuyitunganya
Niba urimo gushakisha ibicuruzwa QT400-18 byuma byuma hamwe na CNC yarangije gutunganya, urashobora shakisha ibicuruzwa byacu byangiza.
QT400-18 vs QT450-10 Icyuma Cyuma
QT400-18 na QT450-10 nibintu bibiri bikunze kwitiranya ibyiciro bya GB ductile ibyuma.
Imbonerahamwe ikurikira irasobanura itandukaniro ryabo kugirango bahitemo ibikoresho.
| Parameter | QT400-18 | QT450-10 |
| Imbaraga Ntoya | 400 MPa | 450 MPa |
| Kurambura Ntarengwa | 18% | 10% |
| Imiterere ya Matrix | Byuzuye ferritic | Ferritic-pearlitic |
| Ubukonje buke | Ibyiza | Hasi |
| Urwego rukomeye | 120–180 HBW | 160-210 HBW |
| Ibyiza Kuri | Ingaruka, serivisi yubushyuhe buke | Imbaraga ziciriritse, ibice rusange byubatswe |
Hitamo QT400-18 mugihe kurambura no kwinjiza ingaruka ari ngombwa.
QT450-10 ihitamo kubisabwa bisaba imbaraga zidasanzwe aho ibisabwa bidasubirwaho.
Ibibazo
QT400-18 irasa nicyuma cya 60-40-18?
QT400-18 ifatwa cyane nkigishinwa gihwanye na ASTM A536 60-40-18, nyamara bisobanuwe mubipimo bitandukanye.
Ikarita ikora gusa kubanza kwerekana ibikoresho.
Ibipimo byose byemewe byemewe bigomba gukurikiza ibipimo ngenderwaho byumushinga.
QT400-18 irashobora gusudwa?
Gusudira birashoboka mubuhanga, ariko bisaba kugenzura neza.
Gushyushya no gukonjesha ni itegeko kugirango wirinde uduce duto kandi dusenyutse.
Guhuza gusudira mubisanzwe bizatakaza igice cyibikoresho fatizo bihindagurika.
Ni irihe tandukaniro riri hagati ya QT400-18 na QT400-18L?
QT400-18L ni ubushyuhe buke.
Ikomeza ingirakamaro ya Charpy ingaruka kubushyuhe bwo hasi kubikoresho bikonje-bidukikije.
Bisanzwe QT400-18 ikubiyemo gusa ibyumba byubushyuhe busabwa.
QT400-18 irakwiriye ibice bidashobora kwambara?
Muri rusange oya. Matrix yoroheje ya ferritic itanga imbaraga zo kurwanya abrasion.
Kubijyanye no kwambara, ibyuma biremereye cyane byuma byuma, ibyuma byangiza cyangwa ibyuma bisobekeranye bigomba gutekerezwa aho.
