Amakuru - "all-rounder" muri plaque ya Carbone

Isahani yicyuma ni kimwe mubyiciro byibanze byibikoresho byibyuma. Ishingiye ku cyuma, hamwe na karubone iri hagati ya 0.0218% -2.11% (igipimo cy’inganda), kandi ikubiyemo oya cyangwa umubare muto wibintu bivanga. Ukurikije ibirimo karubone, irashobora kugabanywamo:
Ibyuma bya karubone(C≤0.25%): gukomera kwiza, byoroshye gutunganya, Q235 ni muriki cyiciro;
Icyuma giciriritse(0,25%)
Ibyuma bya karubone(C> 0,6%): ubukana bukabije cyane n'ubugome bukabije.

Q235 ibyuma bya karubone: ibisobanuro nibipimo byingenzi (GB / T 700-2006 bisanzwe)

Ibigize	C	Si	Mn	P	S
Ibirimo	≤0.22%	≤0.35%	≤1.4%	≤0.045%	≤0.045%

Ibikoresho bya mashini:
Imbaraga zitanga umusaruro: ≥235MPa (uburebure ≤16mm)
Imbaraga zingana: 375-500MPa
Kurambura: ≥26% (uburebure ≤16mm)

Ibikoresho n'imikorere

Ibikoresho:Ibikoresho bisanzwe birimoGR.B, X42, X46, X52, X56, X60, X65, X70, n'ibindi.

Ibiranga imikorere
Imbaraga Zirenze: Ashoboye kwihanganira umuvuduko mwinshi uturuka kumazi nka peteroli na gaze gasanzwe mugihe cyo gutwara.
Gukomera cyane: Ntibyoroshye gucika mugihe byatewe ningaruka zo hanze cyangwa impinduka za geologiya, byemeza imikorere yumutekano.
Kurwanya Ruswa Nziza: Ukurikije ibidukikije bitandukanye nibitangazamakuru, guhitamo ibikoresho bikwiye hamwe nuburyo bwo kuvura hejuru birashobora kurwanya neza ruswa kandi bikongerera igihe cyo gukora umuyoboro.

Q235 "umurwanyi wa mpandeshatu" Ibiranga

Imikorere myiza yo gutunganya
Weldability: Nta gushyushya bisabwa, bikwiranye no gusudira arc, gusudira gazi nibindi bikorwa (nko kubaka ibyuma byo gusudira ibyuma);
Ubukonje bukonje: Irashobora kugororwa byoroshye no gushyirwaho kashe (urugero: gukwirakwiza agasanduku k'igikonoshwa, umuyoboro uhumeka);
Imashini: Imikorere ihamye munsi yo kugabanya umuvuduko muke (gutunganya ibice byimashini).
Impirimbanyi zuzuye

Imbaraga vs Gukomera: 235MPa imbaraga zitanga umusaruro zita ku kwikorera imitwaro no kurwanya ingaruka (ugereranije na 195MPa ya Q195);
Kurwanya Ubuso: Biroroshye gusya no gusiga irangi (nka garanti, ibyuma byoroshye).
Ubushobozi buhebuje mu bukungu
Igiciro kiri munsi ya 15% -20% munsi yicyuma giciriritse-cyuma gikomeye cyane (nka Q345), kibereye gukoreshwa nini.
Impamyabumenyi Yisumbuyeho
Ubunini busanzwe: 3-50mm (ububiko buhagije, kugabanya inzinguzingo);
Ibipimo ngenderwaho: GB / T 700 (murugo), ASTM A36 (bihwanye n’amahanga).

Kugura no Gukoresha "Kwirinda Ubuyobozi"

Kumenyekanisha ubuziranenge:
Kugaragara: nta gucikamo, inkovu, kuzinga (GB / T 709 isahani yerekana isahani);
Garanti: Reba ibihimbano, imiterere yubukanishi na raporo yo kumenya inenge (UT flaw detection irakenewe kubice byingenzi byubaka).
Ingamba zo kurwanya ruswa:
Mu nzu: irangi rirwanya ingese (nk'irangi ritukura ritukura) + ikote;
Hanze: gushyushya-gushiramo (gutwikira ≥85μm) cyangwa gutera fluorocarbon.
Icyitonderwa cyo gusudira:
Guhitamo inkoni: Urukurikirane rwa E43 (nka J422);
Isahani ntoya.
