1.Gufata umupira wibyuma: ibyuma bya chromium ntoya, ibyuma bya chromium yo hagati, ibyuma bya chromium ndende hamwe nicyuma kinini cya chromium (Cr12% -28%).
2.Gukora umupira wibyuma: ibyuma bya karubone nkeya, ibyuma bya karubone yo hagati, ibyuma bya manganese ndende hamwe nubutaka budasanzwe chromium molybdenum alloy ball ball:
Ubu ni ubuhe bwoko bw'umupira w'icyuma aribwo bwiza? Reka noneho dusesengure:
1.Icyuma cyiza cya chromium cyerekana ubuziranenge: ibirimo chromium birenze 10%, ibirimo karuboni muri 1,80% -3,20% byitwa ibyuma bya chromium ndende, ibisabwa murwego rwigihugu rwumupira wo hejuru wa chromium (HRC) bigomba kuba ≥ 58, AK ≥ 3.0J / cm ingaruka zingaruka za
2.Kureka ubuziranenge bwicyuma cya chromium: hamwe 0.5% ~ 2,5%, ibirimo karubone muri 1,80% -3,20% byitwa ibyuma bya chromium nkeya, ibisabwa byigihugu cya chromium ntoya (HRC) bigomba kuba 45, AK ≥ 1.5J / cm ingaruka zingaruka za 2, Umupira uzunguruka kugirango hamenyekane ubuziranenge bwumupira muto wa chromium wumuyaga mwinshi ubushyuhe bukabije cyangwa kuvura umusaza (kugirango ukureho imihangayiko ya casting, nkintego) yumupira wumupira wijimye wijimye kugeza kuri erekana ko ibicuruzwa yabaye ubushyuhe bwo hejuru bwo kuvura, nkumupira wumupira wicyuma ni ibara ryicyuma cyerekana ibicuruzwa bitarinze.
3.Icyerekezo cyiza cyumupira wicyuma: hamwe 0.1% ~ 0.5% (umupira wibyuma udafite chromium), karubone iri munsi ya 1% numupira wicyuma hamwe nubushyuhe bwo hejuru bwo gukora ibicuruzwa, bimwe mubyuma byumupira wibyuma (HRC) ≥ 56 ( nubwo ishobora kugera kurenza kuzimya mm 15 gusa cyangwa irenga), umupira wibyuma kuberako ibyuma byibyuma byahimbwe ibikoresho bikomereye ubushobozi bukomeye ni dogere 30 gusa. Mubihe bisanzwe, umupira wibyuma ukoresheje uburyo bwo kuzimya amazi, umupira wibyuma wacitse ni mwinshi.
4.Gereranya no kwihanganira kwambara: ibyuma bya chromium birenze urugero> ibyuma bya chromium ndende> umupira wo hagati wa chromium> ibyuma bya chromium bike> umupira wibyuma.
Ibigize umupira wibyuma bidashobora kwambara:
Ibirimo bya Chromium ni 1% - 3% nuburemere HRC ≥ 45.Ibipimo byumupira wibyuma bidashobora kwambara byitwa umupira muto wa chromium alloy cast ball. Imipira ya chromium ntoya ifata itanura ryumuriro hagati yumuriro, icyuma cyangwa uburyo bwo guta umucanga. Imikorere yacyo irakwiriye kubirombe bimwe na bimwe bya metallurgjiya, slag hamwe nizindi nganda, zifite uburinganire buke kandi bukoreshwa nabi.
Kwambara imipira yumupira wumupira wa chromium ni 4% kugeza kuri 6% nubukomere HRC ≥ 47.Iyi ngingo ngenderwaho yitwa imipira myinshi ivanze imipira, iruta ibyuma bya chromium nkeya bivuga imbaraga no kwambara birwanya kandi. Ibirimo bya Chromium ni 7% - 10% naho ubukana HRC ≥ 48 ni imipira ya chromium alloy imipira, imikorere yayo nibindi bisumba umupira wibyuma byinshi.
Kwambara imipira yumupira wumupira wa chromium ≥ 10% - 14% hamwe nuburemere HRC ≥ 58. Imipira myinshi ya chromium alloy cast ball ni ubwoko bwumupira wicyuma udashobora kwambara kandi ufite igiciro kinini kandi nigiciro cyiza kumasoko ya none. Ikoreshwa ryayo ni ryagutse kandi rikoreshwa muri metallurgjiya, sima, ingufu zumuriro, gazi ya flulfurizasi, ibikoresho bya magneti, imiti, pompe yamazi yamakara; umupira rero, ifu ya superfine, slag, isazi ivu, calcium karubone ninganda za quartz-sand. Imikorere yacyo iragaragara cyane cyane munganda za sima, zishobora kongera umusaruro no kugabanya gukoresha ingufu.
