Shyushya - irwanya ibyuma bitekesha icyuma cyerekana icyapa

 

Mu byuma hamwe n’ibikoresho byo mu rwego rwo hejuru -, ubushyuhe - ibitonyanga byangiza ibyuma bigomba kwihanganira ibizamini byinshi nkubushyuhe bwinshi, okiside, umunaniro wumuriro nuburemere bwimashini. Guhitamo ibikoresho kuriyi slide bigira ingaruka itaziguye igihe cyo kubaho no guhagarara kwimikorere yibikoresho.

 

 

 

I. ZG40Cr25Ni20Si2. Mu isahani no gusunika gusunika - ibyuma byo gushyushya ibyuma (hamwe nubushyuhe buri hagati ya 1250 - 1300 dogere), ibikoresho byo hejuru - ibikoresho nka ZG40Cr25Ni31WNbRe bigomba gukoreshwa mugice kinini cy'ubushyuhe -. Mu gice cyo hejuru - cy'ubushyuhe bw'isahani no gusunika gusunika - itanura ryo gushyushya ibyuma (hamwe n'ubushyuhe buri hagati ya dogere 1250 - 1300), Si (1.5-2.5%) byongera imitungo irwanya ubushyuhe kandi bigahuza n'imikorere ikonje ikonje. Kurwanya ruswa: Kurwanya aside sulfurike, chloride nibindi bitangazamakuru byangirika, byongerera igihe umurimo wibigize. Urubanza rusanzwe: Igicapo cya ZG40Cr25Ni20Si2 cyakozwe na Wuxi Jiasiyao Heavy Machinery Co., Ltd. cyemeza neza niba hifashishijwe ikoranabuhanga rya casting kandi kigakora imikorere ihamye mu myaka 2 cyangwa irenga mu itanura rishyushya inganda za metallurgie, bikagabanya cyane ibyago by’amazi y’icyuma akonjesha ibimenyetso byirabura no gushushanya hejuru.
2. ZG40Cr25Ni35Nb Ibiranga ibikoresho: Kurwanya ubushyuhe bukabije: Nb element (0.25 - 0.5%) itunganya ibinyampeke, ikongerera imbaraga - imbaraga zubushyuhe hamwe na anti -, kandi ubushyuhe bwakazi ni 100 - 150 hejuru ya ZG40Cr25Ni20Si2. Kwambara birwanya: Ibiri hejuru ya Cr na Ni bihujwe nigisubizo gikomeye gishimangira imbaraga za Nb byongera cyane ubukana bwibikoresho, bikagabanya ubushyuhe bukabije -. Umunaniro urwanya ubushuhe: Ikigereranyo cyimiti igabanya ubukana kugirango ugabanye ingaruka ziterwa nubushyuhe bwumuriro mubihe bikonje-bishyushye. Urubanza rusanzwe: Uruganda rukora ibyuma rwakoresheje amashanyarazi ya ZG40Cr25Ni35Nb mu gice cy’ubushyuhe bwo hejuru bw’isahani hamwe n’itanura rishyushya, byongera ubuzima bwa serivisi kuva ku myaka 1.5 kugeza ku myaka 3, no kugabanya amafaranga yo kubungabunga 40%.
3.. Ultra - irwanya ubushyuhe bwinshi: W element (4 - 5%) itezimbere cyane ubushyuhe bwo hejuru nubushyuhe bwo kurwanya ibintu, hamwe nubushyuhe bwakazi bugera kuri dogere 1400. Kurwanya Oxidation: Ibirungo byinshi (26-30%) na Ni (45-50%) bigize firime ya okiside ihamye, irwanya isuri ikomeye ya okiside. Kurwanya ruswa: Kurwanya bihebuje ibyuma byashongeshejwe, ibishishwa hamwe nibindi bitangazamakuru byangirika, bikwiranye n’ibidukikije bigoye. Urubanza rusanzwe: Igikoresho cya ZG40Cr28Ni48W5 cya Jiangsu Jin Gu Heavy Machinery Co., Ltd. cyakoraga mu gutwika imyanda imyaka 5 cyangwa irenga nta byangiritse cyangwa ngo bihindurwe, biteza imbere cyane imikorere y’ibikoresho.
4. Ibiranga ibikoresho: Ultra - gukomera cyane: Ubukomezi bwa cobalt - bushingiye ku mavuta (HRC 40 - 50) burenze cyane chromium - ubushyuhe bwa nikel - ibyuma byihanganira, hamwe no kunanirwa kwambara inshuro 2 - 3. Imbaraga zubushyuhe bwo hejuru: Co element ituma ibyiciro bya karbide, byemeza ko ibikoresho bigifite imbaraga nyinshi nubushobozi bwo kurwanya deformasiyo mubushyuhe bwinshi. Kurwanya ruswa: Yerekana kurwanya cyane itangazamakuru ryangiza aside na alkaline, ibereye ibidukikije byangiza isuri. Urubanza rusanzwe: Igicapo cya Co40, kugera 4+ imyaka yo gukora idafite kwambara mumashanyarazi ya ceramic, hamwe nubuzima bwikubye inshuro 3 ugereranije nibikoresho gakondo.
5. Ibiranga: Hejuru - ituze ryubushyuhe: 80Ni-20Cr igisubizo cyashimangiye amavuta, hamwe nimiterere ihamye kandi irwanya imigezi myiza. Kurwanya ruswa: Ifite imbaraga nyinshi zo kurwanya okiside no kugabanya itangazamakuru ryangirika, ibereye ibidukikije bigoye. Imikorere yo gutunganya: Irashobora gutunganyirizwa mumpapuro cyangwa ibikoresho byifashishije ubukonje kandi bushyushye kugirango byuzuze ibisabwa bitandukanye. Urubanza rusanzwe: Uruganda rukora imiti rukoresha amashyanyarazi ukoresheje amashanyarazi ya GH3030 rwakoraga ubudahwema kuri dogere 800 mugihe cyimyaka 5 nta guhindagurika cyangwa kwangirika, kuzamura ibikoresho byizewe.
6. Ibiranga ibikoresho: Igiciro - gukora neza: Ibiri hasi ya Cr na Ni, hamwe no kugabanya ibiciro 20-30% ugereranije na ZG40Cr25Ni20Si2. Kurwanya ubushyuhe: Irashobora kugera kuri dogere 1100, yujuje ibyangombwa rusange byo gushyushya inganda. Imikorere yo gutunganya: Imikorere myiza ya casting, ibereye kubyara umusaruro. Ikibazo gisanzwe: Uruganda rutunganya imashini rukoresha amashanyarazi ya ZG35Cr26Ni12 rwageze kumikorere ihamye mumyaka 1.5 mumatanura yo kuvura ubushyuhe, hamwe nigiciro kinini.
