Umupira w'icyuma ukoreshwa mu gusya ukoresheje icyuma cya 10MM kugeza kuri 130MM ukoreshwa mu gusya imigozi y'icyuma n'ibimera bya sima Ishusho yagaragaye

Umupira w'icyuma ukoreshwa mu gusya ukoresheje icyuma gicukura amabuye y'agaciro n'inganda za sima kuva kuri 10MM kugeza kuri 130MM

Ibisobanuro bigufi:

Imipira yo gucukura ya Junda ishobora kugabanywamo ubwoko butandukanye kuva kuri mm 10 kugeza kuri mm 130. Ingano y'imipira yo gucukura ishobora kuba mu bwoko bw'imipira yo hasi, miremire, n'iciriritse. Ibice by'imipira y'icyuma birimo imiterere yoroshye, kandi ushobora kubona umupira w'icyuma ukurikije ingano wifuza. Ibyiza by'ingenzi byo gukoresha imipira yo gucukura ni igiciro gito, imikorere myiza, n'uburyo bunini bwo kuyikoresha, cyane cyane mu nganda z'isima zumye.

Umupira wo gushongesha, witwa kandi umupira wo gushongesha, ukorwa mu byuma bishaje, ibyuma bishaje, n'ibindi bikoresho byakuwemo imyanda. Ibikoresho byavuzwe haruguru birashongesha cyane kandi bigatanga umuyoboro uhoraho nyuma yo gushyuha. Mu gihe cyo gushongesha, ibintu byinshi by'icyuma nka vanadium, icyuma na manganese bibanza kongerwamo umwuka wa flue kugira ngo bigere ku musaruro wifuzwa kandi wagenwe. Ibi bintu bishobora gusuka icyuma cyashongeshejwe cyane mu buryo bw'umusaruro w'uruganda rukora ibyuma.

Intangiriro y'ibicuruzwa by'imipira yo gucukura mu byuma

Imipira ya Chrome cast steel ni imipira isya irimo ijanisha runaka rya chromium, kandi igabanyijemo imipira myinshi ya chromium cast steel, imipira yo hagati ya chromium cast steel n'imipira yo hasi ya chromium steel. Imipira ya chromium cast steel igabanyijemo imipira myinshi ya chromium cast steel, imipira yo hagati ya chromium cast steel n'imipira yo hasi ya chromium cast steel. Ifite imiterere yo gukomera cyane, kwangirika guke, no kwangirika guke, imipira isya steel ikoreshwa cyane cyane mu nganda za sima, mu nganda z'ubucukuzi bw'amabuye y'agaciro, mu nganda z'ibyuma, mu nganda zitanga ingufu n'ubwubatsi.

Ibiranga umupira w'icyuma gisya

1. Ibikoresho fatizo byose bifite ibisigazwa by'icyuma, birimo umuringa, molybdenum, nikeli n'ibindi bintu by'agaciro by'icyuma, bishobora kunoza neza imiterere y'umupira w'icyuma.

2. Ibicuruzwa byacu bikorwa n'itanura ry'amashanyarazi riciriritse rishobora gutuma ibikoresho biguma neza. Imipira ntabwo yoroshye kuyikuraho no kuyihindura mu gihe cyo kuyikoresha. Ndetse ishobora no kugumana urumuri kandi izengurutse nyuma y'igihe kirekire ikora.

3. Umurongo munini ugezweho wo gukora amavuta yikora ni wo ukoreshwa mu kuvura ubushyuhe, ibyo bikaba byemeza ko ibicuruzwa bikomera kandi bingana.

Uburyo butatu bwo gukora imipira y'icyuma

1. Uburyo butatu bwo gukora imipira y'icyuma

Hari ubwoko butatu bw'imikorere y'imipira y'icyuma: gucukura, gucura no gucura.

（1） Gucukura: Ubwiza bw'imipira y'icyuma icukurwa bushingiye ahanini ku gipimo cya chromium. Mu myaka ya vuba aha, izamuka ry'igiciro cya chromium, kurengera ibidukikije, n'ibindi byatumye ikiguzi cy'imipira y'icyuma icukurwa cyiyongera.

（2） Gucukura: Hakoreshejwe icyuma kinini cya manganese nk'ibikoresho fatizo, inyundo zo gucukura zikoreshwa mu buryo bw'umwuka n'ibumba ry'umupira bikoreshwa mu gukora imipira y'icyuma. Imipira y'icyuma icukura ifite uruvange rukwiye rwa karubone nyinshi, manganese, chromium, n'ibindi bintu bya alloy, kandi ifite ubushobozi bwo gukomera mu gutunganya ubushyuhe, itandukaniro rito mu gukomera imbere no hanze, n'itandukaniro mu gaciro k'ingaruka, bituma imipira icukura ikomeye kurusha imipira icukurwa.

（3）Gutemba: Hakoreshejwe ibyuma bifite manganese nyinshi nk'ibikoresho fatizo, imipira y'icyuma ikorwa n'uruganda rutemba rukoresheje imigozi izunguruka.
