Ubushyuhe nuburyo bwo gutunganya ubushyuhe aho akazi kazimye kandi gashyuha kugeza ku bushyuhe buri munsi ya Ac1 (ubushyuhe bwo gutangira pearlite kugirango austenite ihinduka mugihe cyo gushyushya), bifata mugihe runaka, hanyuma bikonjeshwa ubushyuhe bwicyumba.
Ubushyuhe bukurikirwa no kuzimya, hagamijwe:
(a) Kurandura imihangayiko isigaye iterwa mugihe cyo kuzimya akazi kugirango wirinde guhinduka no guturika;
(b) Hindura ubukana, imbaraga, plastike, nubukomezi bwakazi kugirango uhuze ibisabwa kugirango ukoreshwe;
(c) Imiterere ihamye nubunini, byemeza neza;
(d) Kunoza no kuzamura imikorere yo gutunganya. Kubwibyo, kwitonda ninzira yanyuma yingirakamaro yo kubona imikorere isabwa yakazi. Muguhuza kuzimya no gutwarwa, ibikoresho bya mashini bikenewe birashobora kuboneka. [2]
Ukurikije ubushyuhe bwubushyuhe, ubushyuhe burashobora kugabanywa mubushyuhe buke, ubushyuhe bwo hagati, hamwe nubushyuhe bwo hejuru.
Gutondekanya ibyiciro
Ubushyuhe buke
Kugereranya ibihangano kuri 150-250 °
Ikigamijwe ni ugukomeza gukomera no kwambara birwanya ibikorwa byazimye, kugabanya imihangayiko isigaye hamwe nubugome mugihe cyo kuzimya
Tempens martensite yabonetse nyuma yubushyuhe bivuga microstructure yabonetse mugihe cy'ubushyuhe buke bwa martensite yazimye. Ibikoresho bya mashini: 58-64HRC, ubukana bwinshi no kwihanganira kwambara.
Ingano yo gusaba: Ahanini ikoreshwa muburyo butandukanye bwibikoresho byuma bya karubone ndende, ibikoresho byo gutema, ibikoresho byo gupima, ibishushanyo, ibyuma bizunguruka, ibice bya carburize hamwe nubutaka bwazimye, nibindi [1]
Ubushyuhe bwo hagati
Kugereranya igihangano kiri hagati ya 350 na 500 ℃.
Ikigamijwe ni ukugera kuri elastique yo hejuru no gutanga umusaruro, hamwe no gukomera gukwiye. Nyuma yubushyuhe, habonetse troostite yubushyuhe, bivuze imiterere ya duplex ya matrike ya ferrite yakozwe mugihe cya martensite, aho karbide ntoya cyane (cyangwa cimentite) ikwirakwizwa muri matrise.
Ibikoresho bya mashini: 35-50HRC, imipaka ihanitse ya elastike, ingingo yumusaruro, hamwe no gukomera.
Ingano yo gusaba: ikoreshwa cyane cyane kumasoko, amasoko, guhimba bipfa, ibikoresho byingaruka, nibindi [1]
Ubushyuhe bwo hejuru
Kugereranya ibihangano biri hejuru ya 500 ~ 650 ℃.
Ikigamijwe ni ukubona ibintu byose byubukanishi hamwe nimbaraga nziza, plastike, hamwe no gukomera.
Nyuma yo gutwarwa, habonetse sorbite irangwa, bivuze imiterere ya duplex ya ferrite matrix yakozwe mugihe cya martensite, aho karbide ntoya (harimo na sima) ikwirakwizwa muri matrix.
Ibikoresho bya mashini: 25-35HRC, hamwe nibikoresho byiza byuzuye.
Ingano yo gusaba: Ikoreshwa cyane kubintu bitandukanye byingenzi bitwara imitwaro ibice byubaka, nko guhuza inkoni, bolts, ibikoresho, nibice bya shaft.
Uburyo bwo gutunganya ubushyuhe bwo kuzimya akazi no kuzimya ubushyuhe bwo hejuru byitwa kuzimya no gutuza. Kuzimya no gutwarwa ntibishobora gukoreshwa gusa mu kuvura ubushyuhe bwa nyuma, ariko kandi no kubanza kuvura ubushyuhe bwibice bimwe na bimwe cyangwa ibice byazimye。
