Amakuru - "Ikintu cyose" kiri mu cyuma cya karuboni

Isahani y'icyuma cya karuboni ni kimwe mu byiciro by'ibanze by'ibikoresho by'icyuma. Ishingiye ku cyuma, gifite ingano ya karuboni iri hagati ya 0.0218%-2.11% (ibipimo ngenderwaho by'inganda), kandi nta kintu na kimwe kirimo cyangwa igice gito cy'ibintu bivangavanze. Dukurikije ingano ya karuboni, ishobora kugabanywamo:
Icyuma gito cya karuboni(C≤0.25%): gukomera neza, byoroshye gutunganya, Q235 iri muri iki cyiciro;
Icyuma giciriritse cya karuboni(0.25%
Icyuma gifite karubone nyinshi(C>0.6%): gukomera cyane no kugorama cyane.

Icyuma cya karuboni cya Q235: ibisobanuro n'ibipimo by'ingenzi (ibipimo ngenderwaho bya GB/T 700-2006)

Imiterere	C	Si	Mn	P	S
Ibikubiyemo	≤0.22%	≤0.35%	≤1.4%	≤0.045%	≤0.045%

Imiterere ya mekanike:
Ingufu z'umusaruro: ≥235MPa (ubunini ≤16mm)
Ingufu zo gukurura: 375-500MPa
Uburebure: ≥26% (ubunini ≤16mm)

Ibikoresho n'Imikorere

Ibikoresho:Ibikoresho bisanzwe birimoGR.B, X42, X46, X52, X56, X60, X65, X70n'ibindi.

Ibiranga Imikorere
Imbaraga nyinshi: Ishobora kwihanganira umuvuduko mwinshi uterwa n'amazi nka peteroli na gaze karemano mu gihe cyo kuyitwara.
Ubukomere Bukomeye: Ntabwo byoroshye kuvunika iyo habayeho ingaruka zo hanze cyangwa impinduka mu miterere y'ubutaka, bigatuma umuyoboro ukomeza gukora neza.
Ubudahangarwa Bwiza bwo Kurwanya Ingese: Dukurikije imiterere itandukanye y'imikoreshereze n'uburyo butandukanye bwo gutunganya ubuso, guhitamo ibikoresho bikwiye n'uburyo bwo gutunganya ubuso bishobora kurwanya ingese neza no kongera igihe cyo gukora cy'imiyoboro.

Imiterere y' "intwari ifite impande esheshatu" ya Q235

Imikorere myiza cyane yo gutunganya
Ubushuhe: Nta gushyushya mbere bikenewe, bikwiranye no gusudira arc, gusudira gaz n'izindi nzira (nk'ubusudira bw'ibyuma mu bwubatsi);
Gukomera mu gihe cy'ubukonje: Ishobora gupfunyika byoroshye no gushyirwaho kashe (urugero: agasanduku gakwirakwizwamo, umuyoboro w'umwuka uhumeka);
Ubuhanga bwo gukora: Imikorere ihamye mu gihe cyo gukata vuba (gutunganya ibice by'imashini).
Ingano rusange ya Mekanike

Ingufu vs Ubushobozi: Ingufu z'umusaruro wa 235MPa zireba ubushobozi bwo kwihanganira umutwaro n'ubudahangarwa (ugereranije na 195MPa ya Q195);
Uburyo bwo Gutunganya Ubuso Busanzwe: Byoroshye gushyiramo irangi rya galvani na spray (nk'imigozi y'icyuma, imigozi yoroheje y'icyuma).
Imikorere myiza mu bukungu
Igiciro kiri hasi kuri 15%-20% ugereranyije n'icy'icyuma gifite imbaraga nke (nka Q345), gikwiriye gukoreshwa mu buryo bunini.
Impamyabumenyi yo mu rwego rwo hejuru mu bijyanye n'ubuziranenge
Ubunini busanzwe: 3-50mm (imigabane ihagije, bigabanya igihe cyo guhindura ibintu);
Amabwiriza yo gushyira mu bikorwa: GB/T 700 (yo mu gihugu), ASTM A36 (ingana n'iy'amahanga).

Gura no Gukoresha "Ubuyobozi bwo Kwirinda"

Igenzura ry'Ubuziranenge:
Isura: nta mikurire, inkovu, cyangwa imikurire (ibipimo ngenderwaho bya GB/T 709 plate);
Garanti: Reba imiterere, imiterere ya mekanike na raporo yo kubona inenge (gusuzuma inenge ya UT birakenewe ku bice by'ingenzi by'imiterere).
Ingamba zo kurwanya ingese:
Imbere mu nzu: irangi rirwanya ingese (nk'irangi ritukura) + irangi ryo hejuru;
Hanze: gushyushya no gusiga amashanyarazi (gusiga ≥85μm) cyangwa gusiga amavuta ya fluorocarbon.
Ikarita yo gusudira:
Guhitamo inkoni zo gusudira: Urukurikirane rwa E43 (nk'urwa J422);
Isahani nto(≤6mm): nta gushyushya mbere bisaba, isahani nini (>20mm): shyushya mbere 100-150℃ kugira ngo hirindwe ko hacikamo ibice.
