Gukura amenyo bikoreshwa cyane mu bwubatsi bw'inganda zicukura amakara.

Ibisobanuro bigufi:

Uduce tw’amakara dukozwe ahanini n’icyuma gikozwe mu ishingiro n’umutwe w’icyuma gikomeye gikata, hamwe n’ibikoresho gakondo by’icyuma bifite amazina y’ikirango YG11C cyangwa YG13C, birimo ibyuma bikomeye. Uko imirimo yo gucukura amakara yagendaga yiyongera, ikigo cyacu cyakomeje guhanga udushya mu ikoranabuhanga mu gukora. Twakoresheje ibikoresho by’icyuma biciriritse bifite ingano ya cobalt kuva kuri 7% kugeza kuri 9% by’ingano ya cobalt. By’umwihariko, twakoze ibikoresho bitatu, KD205, KD254, na KD128, byakozwe hakurikijwe imiterere itandukanye y’ubucukuzi. Ibi bikoresho bigaragaza ubushobozi bwo kudacika intege, kudashira, no kudakora neza, byongerera ubuzima ubuzima kandi bigatuma abakiriya bacu bakundwa cyane.

Ku biti by'amakara, ikigo cyacu ubu cyihariye mu gukora ubwoko butandukanye, harimo U82, U84, U85, U92, U95, U170, ndetse n'ibice by'imashini ziborera mu miyoboro nka U135, U47, na S100. Dutanga ingano zitandukanye z'umurambararo w'ibirungo, harimo 16, 18, 19, 20, 21, 22, 24, 25, 27, 28, 30, na 35. Ibice by'amakara biborera mu miyoboro akenshi biba bifite imiterere ya silinda, bifite umurambararo uri munsi ya 22 wo gukata amakara, mu gihe umurambararo uri hejuru ya 25 ukoreshwa cyane cyane mu gukata amabuye. Dufite ubwoko bwinshi bw'ibibumbano biboneka, bidufasha gutanga ibicuruzwa byiza by'ibirungo bijyanye n'ikoreshwa n'ibikenewe bitandukanye by'abakiriya bacu mu bucukuzi bw'amabuye y'agaciro.

Porogaramu

1. Amenyo yo gukata amakara akoreshwa cyane ku bikoresho bya mekanike bikoreshwa mu birombe by'amakara. Akoreshwa mu gukata, kumena no gukuramo amakara neza. Ayo menyo akuramo amakara neza mu birindiro by'amakara, bityo bigafasha mu kuyatunganya no kuyatwara nyuma.

2. Amenyo yo gukata amakara ashobora gukoreshwa mu kubaka imiyoboro. Akoreshwa mu gukata no kumena amabuye, ubutaka, n'ibindi bikoresho, bigafasha mu gucukura no kubaka imiyoboro.

3. Kimwe n'uko bikoreshwa mu bucukuzi bw'amakara, amenyo yo gutema amakara ashobora gukoreshwa mu birombe by'amabuye n'ibindi bikorwa byo gucukura amabuye kugira ngo bace kandi bamene amabuye akomeye.

Ibiranga

1. Amenyo yo gukata amakara agomba kugaragaza ubushobozi bwo guhangana n’amakara kuko ahura n’ibintu bikurura cyane nka amakara, amabuye n’ubutaka mu gihe cyo gucukura. Amenyo afite ubushobozi bwo guhangana n’amakara akomeza kubaho igihe kirekire kandi nta mahitamo menshi asimbura ayandi.

2. Amenyo yo gukata amakara akeneye gukomera no gukomera bihagije kugira ngo adahinduka cyangwa ngo avunike mu gihe cyo gukata no kuvunika.

3. Imiterere n'imiterere y'amenyo yo gukata bishobora kugira ingaruka ku mikorere yayo yo gukata. Amenyo yo gukata yakozwe neza ashobora kongera imikorere myiza no gukora neza mu gihe agabanya ikoreshwa ry'ingufu.

4. Imiterere y'amenyo ihamye ishobora gukomeza gukora neza mu gihe hari stress nyinshi, bigabanye ibyago byo kwangirika.

Bitewe n’uko amenyo yo gukata amakara ashobora kwangirika, igishushanyo mbonera cyorohereza gusimbuza ibikoresho byoroshye gishobora kugabanya igihe cyo kudakora no kongera umusaruro.
Amenyo yo gutema amakara akora mu bihe bitandukanye bya geologiya mu birombe bitandukanye by'amakara. Bityo, amenyo meza yo gutema agomba kuba ahuye n'ibintu bitandukanye bya geologiya, nko gukomera no guhumeka.

Muri make, amenyo yo gutema amakara agira uruhare runini mu bucukuzi bw'amakara n'ibindi bijyana nayo. Imiterere yayo, harimo kudashwanyagurika, gukomera, n'imikorere yo gutema, igira ingaruka zitaziguye ku mikorere myiza n'umutekano w'ubucukuzi. Ubwoko butandukanye bw'amenyo yo gutema amakara bukwiriye ahantu hatandukanye ho gukorera n'ibisabwa. Ubushakashatsi buhoraho n'udushya bigira uruhare mu guteza imbere ikoranabuhanga ryo gucukura amakara.

Amakuru y'Ibikoresho

Amanota	Ubucucike (g/cm³)±0.1	Ubukomere (HRA)±1.0	Cobalt(%)±0.5	TRS (MPa)	Porogaramu Isabwa
KD254	14.65	86.5		2500	Ikwiriye gucukurwa mu miyoboro y'amabuye yoroshye no gucukura amakara arimo gangue y'amakara. Ikintu cy'ingenzi ni uko idashobora kwangirika neza kandi igakomeza gukora igihe kirekire. Ibi bivuze ko ishobora gukomeza gukora neza mu gihe ihuye n'ubusa n'ubushyamirane, bigatuma ikwiriye gukoreshwa mu gufata amabuye yoroshye n'ibikoresho bya gangue y'amakara.
KD205	14.7	86		2500	Ikoreshwa mu gucukura amakara no gucukura amabuye akomeye. Ivugwaho kuba ifite imbaraga zikomeye mu guhangana n'umunaniro w'ubushyuhe. Kandi ishobora gukomeza gukora neza mu guhangana n'ingaruka n'ubushyuhe bwinshi, bigatuma ikwiriye ahantu hagoye nko mu birombe by'amakara n'amabuye akomeye.
KD128	14.8	86		2300	Ifite imbaraga zikomeye zo guhangana n’ubushyuhe bwinshi, ikoreshwa cyane cyane mu gucukura imiyoboro y’amazi no mu gucukura amabuye y’agaciro, mu gihe ishobora kwihanganira ingaruka n’ubushyuhe bwinshi.
