Umuyoboro w'icyuma cya karuboni, ni ibikoresho by'ibanze bikoreshwa cyane mu nganda, ugira uruhare runini mu nganda nka peteroli, ubuhanga mu by'ubutabire, n'ubwubatsi. Imiyoboro isanzwe y'icyuma cya karuboni ishyirwa mu byiciro bibiri:umuyoboro w'icyuma udakoranaumuyoboro w'icyuma ushongeshejwe.
Mu bijyanye n'uburyo bwo gukora n'imiterere, umuyoboro w'icyuma udakora ukorwa binyuze mu kuzingira cyangwa gusohora, nta migozi ivanze. Utanga imbaraga nyinshi muri rusange n'ubukomere, ushobora kwihanganira igitutu n'ubushyuhe bwinshi, kandi ukwiriye gukoreshwa bisaba ibisabwa bikomeye mu kurinda imiyoboro.
Ku rundi ruhande, umuyoboro w'icyuma ukozwe hakoreshejwe ibyuma bizingiye kandi bisudira, hamwe n'icyuma kimwe cyangwa byinshi bisudira. Nubwo ibi bitanga umusaruro mwiza kandi bihendutse, imikorere yabyo mu gihe cy'umuvuduko mwinshi n'ibidukikije biremereye ni mike ugereranyije n'imiyoboro idafunze.
Ku miyoboro y'icyuma idakora neza, Q235 na A36 ni amanota akunzwe cyane. Umuyoboro w'icyuma wa Q235 ni urwego rw'icyuma gikoreshwa cyane mu Bushinwa mu byuma bikoreshwa mu buryo bwa karuboni. Ufite imbaraga za 235 MPa, utanga ubushobozi bwo gusudira no kugenda neza ku giciro gito. Ukoreshwa cyane mu kubaka inyubako zishyigikiwe, imiyoboro y'amazi ikoresha umuvuduko muto, n'izindi porogaramu, nko mu miyoboro y'amazi yo mu ngo no mu bwubatsi bw'icyuma bw'inyubako zisanzwe z'uruganda.
Umuyoboro w'icyuma cya karuboni A36ni igipimo gisanzwe cyo muri Amerika. Ingufu zayo zisa n'iza Q235, ariko itanga imbaraga zo gukomera no gukomera cyane. Ikoreshwa cyane mu miyoboro ifite umuvuduko muto mu gukora imashini no gukora peteroli, nko gutunganya ibice bito bya mekanike n'imiyoboro ya peteroli ifite umuvuduko muto mu mirima ya peteroli.
Ku muyoboro w'icyuma ushongeshejwe,Umuyoboro w'icyuma wa Q235 ushongeshejweNanone ni urwego rukunzwe cyane. Bitewe n'uko ihendutse kandi ifite ubushobozi bwo gusudira neza, ikunze gukoreshwa mu mishinga yo kohereza gaze mu mujyi no mu mishinga yo kohereza amazi mu buryo buri hasi. Ku rundi ruhande, umuyoboro wa A36 welded ukoreshwa cyane mu miyoboro y'inganda ifite umuvuduko muto hamwe n'ibisabwa bimwe na bimwe bikomeye, nko gutwara ibikoresho bifite umuvuduko muto mu nganda ntoya zikora imiti.
| Ingano zo kugereranya | Umuyoboro w'icyuma wa Q235 | Umuyoboro w'icyuma cya karuboni wa A36 |
| Sisitemu Isanzwe | Ibipimo ngenderwaho by'Igihugu cy'Ubushinwa (GB/T 700-2006 "Ibyuma by'Ubwubatsi bya Karuboni") | Umuryango w’Abanyamerika ushinzwe ibizamini n’ibikoresho (ASTM A36/A36M-22 "Ibyuma bya karuboni, imiterere, n'udupira byo gukoresha mu byuma") |
| Imbaraga z'umusaruro (Nibura) | 235 MPa (ubunini ≤ 16 mm) | 250 MPa (mu bunini bwose) |
| Ingufu zo Gufata | 375-500 MPa | 400-550 MPa |
| Ibisabwa ku bukomere bw'ingaruka | Ikizamini cy’ingaruka cya -40°C gikenewe gusa ku manota amwe n’amwe (urugero, Q235D); nta gisabwa gisabwa ku manota asanzwe. | Ibisabwa: Ikizamini cy'ingaruka -18°C (ibipimo by'igice); gukomera mu bushyuhe buri hasi ni byiza gato ugereranyije n'amanota asanzwe ya Q235 |
| Ingero z'ingenzi z'ishyirwa mu bikorwa | Ubwubatsi bw'ibyatsi (inyubako z'ibyuma, inkingi), imiyoboro y'amazi/gaze ifite umuvuduko muto, n'ibice rusange bya mekanike | Inganda zikora imashini (ibice bito n'ibiciriritse), imiyoboro y'amazi ikoresha ingufu nke, imiyoboro y'amazi ikoresha ingufu nke mu nganda |
Muri rusange, imiyoboro y'icyuma idakora kandi ivanze ifite ibyiza byayo. Mu gihe cyo kugura, abakiriya bagomba kuzirikana ibisabwa ku muvuduko n'ubushyuhe by'ikoreshwa ryihariye, ndetse n'ingengo y'imari yabo, bagahitamo urwego rukwiye, nka Q235 cyangwa A36, kugira ngo barebe ko umushinga ufite ireme n'umutekano.
