Q235C ipuleti lensimbi

I-Q235B steel plate iwuhlobo lwensimbi enekhabhoni ephansi. I-GB/T 700-2006 ejwayelekile kazwelonke "Carbon Structural Steel" inencazelo ecacile. I-Q235B ingenye yemikhiqizo yensimbi evamile eChina. Ayibizi futhi ingasetshenziswa emikhiqizweni eminingi engadingi ukusebenza okuphezulu.

Indlela:
(1) Yakhiwe ngophawu lwebanga elingu-Q + inombolo + lwezinga lekhwalithi + uphawu lwe-deoxidation. Inombolo yayo yensimbi ifakwe kuqala ngo-"Q" ukuze imele iphuzu lokukhiqiza lensimbi, futhi izinombolo ezilandelayo zimelela inani lephoyinti lokukhiqiza ku-MPa. Isibonelo, i-Q235 imele insimbi yesakhiwo sekhabhoni enephuzu lokukhiqiza (σs) lama-235 MPa.
(2) Uma kunesidingo, uphawu lwezinga lekhwalithi kanye nendlela ye-deoxidation ingaboniswa ngemva kwenombolo yensimbi. Uphawu lwezinga lekhwalithi ngu-A, B, C, D. uphawu lwendlela ye-deoxidation: F imele insimbi ebilayo; b Imele insimbi ebulalayo kancane; Z imele insimbi ebulewe; I-TZ isho i-Special Kill Steel. Insimbi ebulewe ingase ingabi nalo uphawu, okungukuthi, kokubili u-Z no-TZ kungashiywa kungaphawulwanga. Isibonelo, i-Q235-AF imele i-Class A yensimbi ebilayo.
(3) Insimbi yensimbi yenjongo ekhethekile, njengensimbi yebhuloho, insimbi yomkhumbi, njll., ngokuyisisekelo yamukela indlela yokubonisa yensimbi yesakhiwo sekhabhoni, kodwa yengeza uhlamvu olubonisa injongo ekupheleni kwenombolo yensimbi.

Sebenzisa:
I-Q235B inobude obuthile, amandla, ukuqina okuhle nokusika, futhi kulula ukuyigxiviza nokushisela. Isetshenziswa kabanzi ekwenzeni izingxenye ezijwayelekile zemishini. Isetshenziswa kakhulu ukushisela izingxenye zesakhiwo ezinezidingo zekhwalithi ephezulu kwezokwakha kanye nobunjiniyela bebhuloho.

I-AB ihlukanisa umehluko phakathi kwe-Q235A ne-Q235B
: Izinsimbi zonke ziyinsimbi ye-carbon. Esilinganisweni sikazwelonke se-GB700-88, umehluko wezinto ezibonakalayo phakathi kwe-Q235A ne-Q235B ikakhulukazi usekuqukethwe kwekhabhoni yensimbi. Okuqukethwe kwekhabhoni ye-Q235A impahla yi-0.14-0.22%;
Ibhodi le-Q235A alikwenzi ukuhlolwa komthelela, kuyilapho i-Q235B yenza ukuhlolwa komthelela wegumbi lokushisa kwe-V-notch. Uma sikhuluma nje, izakhiwo zensimbi ezenziwe nge-Q235B zingcono kakhulu kunalezo ezenziwe nge-Q235A.
Ngaphansi kwezimo ezijwayelekile, izigayo zensimbi zimaka iphrofayili eqediwe epuleti lokuhlonza ngaphambi kokuphuma embonini. Abasebenzisi banganquma ukuthi ingabe okokusebenza kupuleti lokuhlonza kuyi-Q235A, Q235B noma enye into. Ukucindezela komklamo P≤ 1.6MPa; Izinga lokushisa lokusebenza 0~350 ° C; Ubukhulu bepuleti lensimbi >=20mm
