Q235C icyuma

Icyuma cya Q235B ni ubwoko bwibyuma bya karubone. Igipimo cyigihugu GB / T 700-2006 "Carbone Structural Steel" gifite ubusobanuro busobanutse. Q235B ni kimwe mu bicuruzwa bikoreshwa cyane mu Bushinwa. Ntibihendutse kandi birashobora gukoreshwa mubicuruzwa byinshi bidasaba gukora cyane.

Uburyo:
(1) Igizwe na Q + umubare + ikimenyetso cyiza cyiza + ikimenyetso cya deoxidation. Umubare wibyuma byashyizwemo na "Q" kugirango ugaragaze umusaruro wibyuma, naho imibare ikurikira yerekana agaciro kerekana umusaruro muri MPa. Kurugero, Q235 yerekana ibyuma byubaka karubone hamwe numusaruro (σs) wa 235 MPa.
(2) Iyo bibaye ngombwa, ikimenyetso cyurwego rwiza hamwe nuburyo bwa deoxidation burashobora kwerekanwa nyuma yumubare wibyuma. Ikimenyetso cyiza cyiza ni A, B, C, D. ikimenyetso cyuburyo bwa deoxidation: F igereranya ibyuma bitetse; b Yerekana ibyuma byica igice; Z igereranya ibyuma byiciwe; TZ bisobanura ibyuma bidasanzwe byica. Ibyuma byishe ntibishobora kugira ikimenyetso cyerekana, ni ukuvuga, Z na TZ zombi zishobora gusigara zitamenyekanye. Kurugero, Q235-AF igereranya Icyiciro A icyuma gitetse.

Koresha:
Q235B ifite uburebure, imbaraga, gukomera no gukomera, kandi biroroshye gushiraho kashe no gusudira. Irakoreshwa cyane mugukora ibice rusange byubukanishi. Ikoreshwa cyane cyane mu gusudira ibice byubatswe hamwe nibisabwa byujuje ubuziranenge mubwubatsi no kubaka ikiraro.

AB itandukanya itandukaniro hagati ya Q235A na Q235B
: Ibyuma byose ni ibyuma bya karubone. Mu rwego rwigihugu GB700-88, itandukaniro ryibintu hagati ya Q235A na Q235B ahanini biri mubirimo karubone yibyuma. Carbone yibikoresho bya Q235A ni 0.14-0.22%;
Ubuyobozi bwa Q235A ntabwo bukora ikizamini cyingaruka, mugihe Q235B ikora ikizamini cyubushyuhe bwicyumba cya V-notch. Ugereranije, imiterere yubukorikori bwibyuma bikozwe muri Q235B nibyiza cyane kuruta ibya Q235A.
Mubihe bisanzwe, insyo zicyuma ziranga umwirondoro wuzuye kuri plaque iranga mbere yo kuva muruganda. Abakoresha barashobora kumenya niba ibikoresho biri ku cyapa kibaranga ari Q235A, Q235B cyangwa ibindi bikoresho. Igishushanyo mbonera P≤ 1.6MPa; Ubushyuhe bukora 0 ~ 350 ° C; Uburebure bw'icyuma> = 20mm
