Umuyoboro w'icyuma udafite ikizinga usobekeranye n'umuyoboro wose w'icyuma uzengurutse, nta gusudira hejuru y'umuyoboro w'icyuma, witwa umuyoboro w'icyuma udafite kashe.Ukurikije uburyo bwo kubyaza umusaruro, umuyoboro wicyuma udafite kashe urashobora kugabanywamo umuyoboro wicyuma ushyushye udafite icyuma, umuyoboro wicyuma ukonje udafite icyuma, umuyoboro wicyuma ukonje utagira kashe, umuyoboro wicyuma udafite kashe, umuyoboro wicyuma udafite icyuma, umuyoboro wa jacking, nibindi. Ukurikije imiterere yiki gice, nta kashe. umuyoboro w'icyuma urashobora kugabanywamo ubwoko bubiri: umuyoboro uzengurutse n'umuyoboro udasanzwe.Umuyoboro udasanzwe ufite kare, oval, mpandeshatu, impande esheshatu, imiterere yimbuto ya melon, imiterere yinyenyeri nuburyo bwinshi bugoye bufite amababa.Diameter ntarengwa ni 900mm, naho diameter ntarengwa ni 4mm.Ukurikije imikoreshereze itandukanye, hariho urukuta rwinshi rutagira umuyoboro wicyuma hamwe nurukuta ruto rutagira icyuma.Umuyoboro w'icyuma udafite ubudodo ukoreshwa cyane cyane mu gucukura peteroli ya geologiya, umuyoboro ucuruza inganda za peteroli, umuyoboro wa boiler, umuyoboro utwara imiyoboro hamwe n'umuyoboro w'icyuma wubatswe neza cyane ku binyabiziga, ibinyabiziga n'indege.
Ibigize imiti yibyuma byuzuye birimo karubone C, silikoni Si, manganese Mn, Sulfuru S, Fosifore P, Chromium Cr, ugereranije nicyuma gikomeye nkicyuma kizunguruka, umuyoboro wicyuma udafite uburinganire ufite uburemere bworoshye mugihe imbaraga zunamye nimbaraga za torsional ari zimwe .Nigice cyubukungu cyicyuma kandi gikoreshwa cyane mugukora ibice byububiko hamwe nimashini Ibigize.
