Kwambara ibyuma birwanya ibyuma:
(1) NM360 (irwanya kwambara 360)
Kwita Izina: N ni ukurwanya (nai) M ninyuguti ya mbere ya pinyin yinyuguti ebyiri zishinwa zo gusya (mo), naho 360 igereranya ubukana bwa Brinell buringaniye bwibyapa.
Kuvura ubushyuhe: ubushyuhe bwo hejuru ubushyuhe, kuzimya + ubushyuhe (kuzimya no gutuza)
Gusaba: Urupapuro rwuma rwihanganira NM360 rukoreshwa cyane mumashini yubucukuzi, imashini zicukura amakara, ibidukikije
Irakoreshwa kandi nkibikoresho bikomeye byubaka ibyuma bifite imbaraga ≥ 700MPa.Ni cyane cyane kurinda ibihe cyangwa ibice bigomba kwihanganira kwambara, kugirango ibikoresho bigire igihe kirekire, kugabanya igihe cyo kubungabunga biterwa no kubungabunga, kandi bikagabanya ishoramari.
Imikorere: Umusaruro urenga 800, kandi imbaraga zingana zirenga 1000.
(2) NM400
NM400 nicyuma kinini-cyuma cyihanganira kwambara.NM400 ifite imbaraga zo hejuru cyane;imiterere yubukanishi yikubye inshuro 3 kugeza kuri 5 iy'ibisanzwe bisanzwe byoroheje;irashobora kunoza cyane kwihanganira kwambara ibice bifitanye isano nubukanishi;bityo kuzamura ubuzima bwa serivisi yimashini no kugabanya ibiciro byumusaruro.Ubuso bukomeye bwibicuruzwa mubisanzwe bigera kuri 360 ~ 450HB.Ibyuma byubaka byubatswe mugutunganya no gukora ibice bidashobora kwangirika kandi byoroshye kubimina hamwe nimashini zitandukanye zubaka.
Urupapuro rwa NM400 rudashobora kwangirika rukoreshwa cyane mu mashini zubaka, imashini zicukura amabuye y'agaciro, imashini zicukura amakara, imashini zita ku bidukikije, imashini za metallurgji n'ibindi bicuruzwa.Ubucukuzi, umutwaro, isahani ya buldozer isahani, isahani yuruhande, isahani yuruhande, icyuma.Crusher liners, blade.
(3) Mn13 (ibyuma bisanzwe bya manganese)
Mn13 nicyuma kinini cya manganese idashobora kwambara (HIGH MANGANESE STELL SCRAP), ikaba ari ihitamo ryiza mubikoresho birwanya kwambara nkingaruka zikomeye no kwambara ibintu byumuvuduko mwinshi.
Hariho ibintu bibiri binini biranga ibyuma birebire bya manganese: kimwe nuko uko ingaruka nyinshi ziva hanze, niko birwanya kwambara kwubuso bwacyo.Iyo bigira ingaruka, ubukana bwacyo buziyongera vuba kuva HB200 kugera hejuru ya HB700, bityo bibyare hejuru yihanganira kwambara.Austenite murwego rwimbere rwicyuma kiracyakomeza ingaruka nziza;icya kabiri ni uko hamwe no kwambara buhoro buhoro hejuru yubutaka bukomeye, imirimo mishya-ikomeye izakomeza gushingwa.
Icyuma cya Mn13 kizungurutse gifite imbaraga zo kwihanganira kwambara gukomeye no kwambara cyane, ntizavunika mugihe cyo gukoresha, kandi gifite ibikoresho byoroshye nko gukata, gusudira, no kunama.
Ubusanzwe ikoreshwa cyane ya chromium ikora ibyuma bifite imbaraga zo kwihanganira kwambara gusa.Mn13 isahani yicyuma irashobora kugabanya neza ikiguzi cyo gukoresha ibice byibikoresho, kuzigama amafaranga yo gufata neza ibikoresho, no kuzamura ubushobozi bwibicuruzwa byarangiye.
Nyamara, kwihanganira kwangirika kwicyuma kinini cya manganese byerekana ubukuru bwacyo gusa mubihe bihagije kugirango imirimo ikomere, kandi irakennye mubindi bihe.
Ubusanzwe icyuma cya Mn17 cyihanganira kwambara cyane-manganese ni ukongera ubwinshi bwa manganese hashingiwe ku cyuma cya Mn13, kizamura ituze rya austenite kandi kikanarinda kugwa kwa karibide, bityo bikazamura imbaraga na plastike yicyuma no kunoza akazi gukomera kwicyuma.no kurwanya abrasion.Kurugero, ubuzima bwa serivisi ya ZGMn18 ya gari ya moshi ikoreshwa mumajyaruguru ni 20% ~ 25% hejuru ya ZGMn13.
Impamyabumenyi hamwe nubunini bwokoresha ibyuma bya manganese muremure bikoreshwa mubushinwa ni: ZGMn13-1 (C 1.10% ～ 1.50%) ikoreshwa mubice bito bito, ZGMn13-2 (C1.00% ～ 1.40%) ikoreshwa kuri ibice bisanzwe, ZGMn13- 3 (C0.90% ~ 1,30%) ikoreshwa mubice bigoye, naho ZGMn13-4 (C0.90% ~ 1,20%) ikoreshwa mubice byingenzi.Ibiri muri manganese biri mu byiciro bine byavuzwe haruguru ni 11.0% kugeza 14.0%.
Mugusudira no gusana, electrode ya manganese-nikel ishingiye kuri austenite (ubwoko bwa D256 cyangwa D266) igomba guhitamo, hamwe nibisobanuro birebire kandi binini, φ3.2mm × 350mm, kandi igipfundikizo cyo hanze ni alkaline.Uburyo bwo gukora bukoresha DC ihuza ihuza, ntoya, arc yoroheje, isaro ntoya yo gusudira hamwe nuburyo bwinshi bwo gusudira, kandi burigihe ikomeza ubushyuhe buke nubushyuhe buke.Gukubita mugihe cyo gusudira kugirango ukureho imihangayiko.Ibyingenzi byingenzi bigomba kuba bifite amakosa.Gusudira kwa Flash (Imashini yo gusudira ya GAAS80 / 700 yo mu Busuwisi) cyangwa gusudira MAG (nka Nissan YD-S-500) irashobora gukoreshwa mu gusudira cyane, bishobora kwemeza neza uburyo bwo gusudira.
Umugereka wa 1: Igitekerezo cyo gukomera
Gukomera nigikorwa cyo gupima ubworoherane nubukomezi bwibikoresho.Hariho uburyo bwinshi bwo kugerageza gukomera, amahame ntabwo arimwe, kandi ibipimo byapimwe ubukana hamwe nibisobanuro ntabwo ari bimwe.Ikigaragara cyane ni static load indentation method hardness test, aribyo gukomera kwa Brinell (HB), gukomera kwa Rockwell (HRA, HRB, HRC), Vickers gukomera (HV), reberi ya plastike ya Shore ikomeye (HA, HD) nubundi gukomera Agaciro kayo kerekana ubushobozi bwubuso bwibikoresho byo kurwanya kwinjira mubintu bikomeye.Gukomera ntabwo ari ibintu byoroshye byumubiri, ahubwo ni indangagaciro yuzuye yerekana ibintu byoroshye, plastike, imbaraga nubukomezi bwibikoresho.
Gukomera kwicyuma: Izina ryimyandikire yubukomezi bwicyuma ni H. Ukurikije uburyo butandukanye bwo gupima ubukana, hariho imvugo ikurikira.
Imvugo isanzwe irimo Brinell (HB), Rockwell (HRC), Vickers (HV), Leeb (HL) gukomera, nibindi, muri byo HB na HRC zikoreshwa cyane.
● HB ifite uburyo butandukanye bwo gukoresha, kandi ikoreshwa muri rusange iyo ibikoresho byoroshye, nk'ibyuma bidafite fer, ibyuma mbere yo kuvura ubushyuhe cyangwa nyuma yo gufatana.HRC ibereye ibikoresho bifite ubukana bwo hejuru, nkubushyuhe bwo kuvura ubushyuhe, nibindi.
Itandukaniro riri hagati yibi byombi ni uko iperereza ryabagerageza gukomera ritandukanye.Iperereza ryikizamini cya Brinell ni imipira yicyuma, mugihe iperereza ryikizamini cya Rockwell ni diyama.Mubihe bimwe, HB na HRC birashobora kungurana ibitekerezo hejuru kumeza.Imiterere yo kubara mumutwe irashobora kwandikwa hafi nka: 1HRC≈1 / 10HB.
● HV ibereye gusesengura microscopique.Gukomera kwa Vickers (HV) gukanda hejuru yibikoresho bifite umutwaro uri munsi ya 120kg hamwe na diamant kare ya cone indent ifite inguni ya vertex ya 136 °, kandi ubuso bwubuso bwurwobo rwibikoresho bigabanijwe numutwaro. agaciro, aribwo Vickers gukomera agaciro (HV).Ubukomezi bwa Rockwell (HR-) bugenwa nuburebure bwimiterere ya plastike ya indentation kugirango hamenyekane agaciro kerekana agaciro.Biroroshye gukora, byihuse kandi byihuse, kandi birakwiriye kubyara umusaruro.
