Ihame shingiro: Ibirimo chromium yo hejuru itanga M₇C₃ chromium karbide ibyiciro bikomeye. Ikigereranyo cya Cr / C hagati ya 4 na 8 itanga ikwirakwizwa rya karbide imwe kandi ikomeza, kuringaniza imyambarire no gukomera.
2. Imiterere ya Metallografiya & Kugereranya Umutungo wa mashini
Ibikoresho byose uko ari bitatu bigizwe na martensite yubushyuhe, M₇C₃ karbide zikomeye na ntoya yagumanye austenite. Microhardness ya karbide igera kuri HV1800 ~ 2200, ikora nk'imyenda yibanze - irwanya skeleton.

Itandukaniro mubikorwa Logic
Cr15: Chromium nkeya hamwe na karbide nkeya. Gabanya gahoro gahoro ariko igiciro gito cyibikoresho fatizo. Icyifuzo cyo hasi - abrasion akazi keza hamwe nibiciro byambere.
Cr20: Urwego rwa chromium uringaniza hamwe nubucuruzi buteganijwe - hagati yukwambara kwambaye, gukomera nigiciro. Ibikoresho nyamukuru byifashishwa cyane mubikorwa bya sima nubucukuzi.
Cr26: Ibintu byinshi bya chromium byongera cyane urugero rwa karbide, bigatanga hejuru - gukomera kurwego, kwambara birwanya, hejuru - kurwanya ubushyuhe hamwe na aside - kurwanya isuri. Gusa ikitagenda neza nigiciro kinini cyibikoresho fatizo.
3. Uburyo busanzwe bwo kuvura ubushyuhe (Ibyingenzi mubuzima bwa serivisi)
Kuzimya no gutondeka byuzuye ni itegeko kuri chromium ndende. Nkuko - abakora ibishushanyo bagera kuri HRC40 ~ 46 gusa, hamwe no kwihanganira kwambara munsi ya 60% yubushyuhe bujuje ibisabwa - ibicuruzwa bivuwe.
Cr15 (KmTBCr15Mo) Kuzimya: Fata kuri dogere 940 ~ 980 mumasaha 2 ~ 4, ukonje hamwe no kuzimya; Ubushyuhe: Ubushyuhe buke - ubushyuhe bwa dogere 220 ~ 280 kumasaha 3 ~ 6 kugirango ugabanye imihangayiko y'imbere; Gukomera kwanyuma HRC Ikomeye cyangwa ihwanye na 59.
Cr20 (KmTBCr20Mo) Kuzimya: Komeza kuri dogere 980 ~ 1030 kumasaha 2 ~ 5; Ubushyuhe: Ubushyuhe buke - ubushyuhe kuri dogere 230 ~ 290; Gukomera kwiza HRC60 ~ 62.
Cr26 (KmTBCr26) Kuzimya: Fata kuri dogere 1010 ~ 1060 kumasaha 3 ~ 6 kugirango ushonga burundu karbide; Ubushyuhe: Fata kuri dogere 250 ~ 300 kumasaha 4 ~ 8; Gukomera gushikamye hejuru ya HRC62. Ubushyuhe burashobora kuzamurwa gato kuri - serivise yubushyuhe kugirango yongere ubushyuhe bwumuriro.
Gutunganya kirazira: kuzimya ikirere gisanzwe no kuzimya hejuru ya dogere 400 birabujijwe rwose, bigabanya cyane ubukana no kurwanya abrasion.
4. Ibikorwa Byakoreshwa Mubikorwa, Ibikoresho & Ibikoresho kuri buri cyiciro cya Liner
4.1 Cr15 Ikomeye ya Chromium Liner (Icyiciro cyubukungu)
Scenarios ikoreshwa: Gukuramo hasi, gusya - urusyo rwumupira wa diametre, ibikoresho byoroheje, umusaruro wigihe gito Ibikoresho: Uruganda ruto ruto Φ Ntirurenze cyangwa rungana na 2,4m, urusyo rwamakara, uduce duto duto twumusenyi, { Amafaranga yo gusimbuza Ibibi: Ubuzima bwa serivisi bugufi munsi - ubutare bukomeye kandi bukomeza byuzuye - ibikorwa byo gutwara; Ntibikwiriye gusya neza hamwe na acide acide Biteganijwe mubuzima bwa serivisi: imyaka 3 ~ 5, bihwanye na 60% ~ 70% gusa yubuzima bwa serivisi ya Cr20 kumurongo umwe.
4.2.
Ibintu byakoreshwa: Gukuramo hagati, gukama no gutose kabiri - intego, sima isanzwe / ubucukuzi bwamabuye y'agaciro, kuringaniza imyambaro & igiciro Ibikoresho: Kuringaniza kwambara no gukomera, birwanya ingaruka ziciriritse, bihujwe no gusya byumye & wet, gukora neza igiciro cyiza Ibibi: Ntibisanzwe kumurongo wa Cr26 munsi ya ultra - amabuye y'agaciro akomeye (basalt, umusenyi wa emery) hamwe nubushyuhe bukabije - isuri Ubushyuhe buteganijwe Ubuzima bwa serivisi: Imyaka 5 ~ 8, 1.5 ~ 1.8 kurenza uburebure bwa Cr15
4.3.
Scenarios ikoreshwa: Kwambara gukabije, ubushyuhe bwinshi, acide acide, binini - inganda za diametre, umusaruro uhoraho hamwe n’ibikoresho fatizo - ibikoresho bikomeye hejuru - silicon quartz, amabuye y'icyuma akomeye, hejuru - clinker yubushyuhe, sulfure - irimo aside irike Ibyiza: Kurwanya kwambara hejuru, hejuru ya - kurwanya ubushyuhe bwa okiside, aside & alkali irwanya isuri, imikorere yumunaniro mwinshi wihuta, idafite ibiciro byihuse byo kugura ibicuruzwa; Kurenza umubyimba - urukuta rurerure rwa manganese ibyuma byibasiwe cyane nibikoresho byinshi Byateganijwe Ubuzima bwa Serivisi: Imyaka 7 ~ 10, inshuro 2 ~ 3 kurenza Cr15 na 1.4 ~ 1.7 kurenza Cr20 mugihe kimwe gikora
5. Imiterere ya Liner & Tekinoroji Yingenzi
Uburyo bwo kubumba: Gutakaza ifuro ryuzuye cyangwa guta umucanga kugirango ushyire hamwe muburyo bwo guhuza imirongo, imirongo yo guterura intambwe, imirongo igororotse hamwe nimpera zanyuma. Ibikoresho bya Cr26 bifite igipimo kinini cyo kugabanuka, kuburyo ibishushanyo bisaba amafaranga yinyongera yo kugabanuka.
Anti {{0} Design Igishushanyo mbonera: Imirongo ifite uburebure burenze 60mm ivangwa na molybdenum na vanadium kugirango itunganyirize ingano. Ubukonje bwimbere bushyirwa kumurongo munini kugirango wirinde gutandukanya karbide no gukomera.
Guhuza Kwishyiriraho: Pre - yabitswe umwobo wa bolt imwe - gusimbuza igice. Ugereranije nicyuma kinini cya manganese, imirongo ya chromium irashobora kuba yoroheje 15% ~ 25% murwego rwo kurwanya kwambara, kugabanya imizigo no gukoresha ingufu.

7. Ibikorwa & Kubungabunga Inyandiko
Imipaka ntarengwa: Ibyiciro bitatu byose ni urwego - kwambara gake - ibikoresho birwanya. Kubisya binini byo gusya hamwe nubunini bwibiryo burenga 100mm, ibyuma bya manganese ndende cyangwa bimetallic compteur linite byashyizwe imbere kugirango birinde gucika kumurongo wa chromium muremure.
Ibidukikije byangirika: Cr26 ni itegeko kuri sulfuru - irimo na acide acide; Cr15 irwaye ruswa yihuta.
Kugabanya Ubushyuhe: Cr26 yonyine niyo ikomeza imikorere ihamye munsi yigihe kirekire - ubushyuhe bwakazi burenga dogere 350. Uburebure - igihe kinini {{5} service serivisi yubushyuhe yoroshya Cr15 ikoresheje ubushyuhe, kwikuba kabiri gutakaza.
Kwishyiriraho no Kubungabunga: Birabujijwe gusudira no gukata imirongo ya chromium ndende birabujijwe, kuko gusudira hejuru - gusudira kubyara ibice. Uzuza icyuho kiri hagati yumurongo wambaye - idashobora kwihanganira mugihe cyo kwishyiriraho kugirango wirinde isuri yibintu kuri bolts.
8. Igiciro & Inyungu Zuzuye Inyungu
Cr15: Ishoramari ryo hasi cyane ariko guhagarika kenshi kubasimbuye. Bikwiranye ninganda nto - ubushobozi hamwe nigihombo gito cyo hasi.
Cr20: Ibyiza muri rusange byuzuye, iboneza rya 80% bya sima hamwe na - mines nto.
Cr26: Isumbabyose - igiciro cyamasoko nyamara inshuro ebyiri gusimburwa. Igikorwa gito muri rusange nigikorwa cyo gufata neza kumurongo munini uhoraho, bikagabanya cyane igihombo cyubukungu cyatewe nigihe gito cyo gukora.
