Nhau - "Yakazara" muCarbon Steel Plate

Purati yesimbi yekabhoni ndeimwe yemhando dzesimbi dzakakosha. Yakavakirwa pasimbi, ine kabhoni iri pakati pe0.0218%-2.11% (muyero weindasitiri), uye haina kana huwandu hushoma hwezvinhu zvinosanganisa alloying. Zvichienderana nehuwandu hwekabhoni, inogona kukamurwa kuita:
Simbi ine kabhoni shoma(C≤0.25%): kusimba kwakanaka, kuri nyore kugadzirisa, Q235 ndeyechikamu ichi;
Simbi yekabhoni yepakati(0.25%
Simbi ine kabhoni yakawanda(C>0.6%): kuomarara kwakanyanya uye kuputsika kwakanyanya.

Q235 simbi yekabhoni: tsananguro uye ma core parameters (GB/T 700-2006 standard)

Kuumbwa	C	Si	Mn	P	S
Zviri Mukati	≤0.22%	≤0.35%	≤1.4%	≤0.045%	≤0.045%

Hunhu hwemakanika:
Simba rekupa: ≥235MPa (ukobvu ≤16mm)
Simba rekudhonza: 375-500MPa
Kureba: ≥26% (ukobvu ≤16mm)

Zvinhu uye Mashandiro

Zvinyorwa:Zvinhu zvakajairika zvinosanganisiraGR.B, X42, X46, X52, X56, X60, X65, X70, nezvimwewo.

Hunhu hweKushanda
Simba Rakakwirira: Inokwanisa kutsungirira kumanikidzwa kwakanyanya kunokonzerwa nemvura dzakadai semafuta negasi rechisikigo panguva yekufambisa.
Kusimba Kwakakwirira: Hazvisi nyore kutyoka kana paine kuputika kwekunze kana shanduko dzejeologi, zvichiita kuti pombi ishande zvakachengeteka.
Kuramba Kuora Kwakanaka: Zvichienderana nenzvimbo dzakasiyana dzekushandisa uye nzira dzekushandisa, kusarudza zvinhu zvakakodzera uye nzira dzekugadzirisa pamusoro pemvura zvinogona kudzivirira ngura zvinobudirira uye kuwedzera hupenyu hwebasa repombi.

Hunhu hwe "murwi ane magokora matanhatu" weQ235

Kushanda Kwakanaka Kwekugadzirisa
Kugona kusundira: Hapana kudziya kunodiwa, kwakakodzera kusanganisa arc welding, gas welding nezvimwe zvinhu (zvakadai sekusanganisa simbi muchivako);
Kuumbwa kwechando: Inogona kukotama uye kudhindwa zviri nyore (semuenzaniso: goko rebhokisi rekugovera, nzira yekufema);
Kugona kuchinjika: Kushanda kwakagadzikana pasi pekucheka kunokurumidza (kugadzirisa zvikamu zvemuchina).
Kuenzanisa Kwakazara Kwemakanika

Simba vs Kusimba: 235MPa simba rekupa rinofunga nezvekudzivirira mutoro uye kuramba simba (zvichienzaniswa ne195MPa yeQ195);
Kugadziriswa Kwekurapa Kwepamusoro: Zviri nyore kupenta nekuisa galvanize uye kupfapfaidza pendi (senge maguardrails, ma keel esimbi akareruka).
Kushanda Zvakanaka Kwehupfumi
Mutengo wacho wakaderera ne15%-20% pane wesimbi ine simba rakawanda (yakadai seQ345), yakakodzera kushandiswa pakukura kukuru.
Dhigirii Repamusoro reKugadzika
Ukobvu hwakajairika: 3-50mm (yakaringana, zvichideredza kutenderera kwekugadzirisa);
Mipimo yekushandisa: GB/T 700 (yemuno), ASTM A36 (yakaenzana nenyika).

Tenga uye Shandisa "Gwaro reKudzivirira"

Kuzivikanwa Kwemhando Yepamusoro:
Chitarisiko: hapana mitswe, mavanga, mapete (GB/T 709 plate shape standard);
Garandi: Tarisa maumbirwo, hunhu hwemakanika uye mushumo wekuona zvikanganiso (kuonekwa kwezvikanganiso zveUT kunodiwa kune zvikamu zvakakosha zvechivakwa).
Nzira yekudzivirira ngura:
Mumba: pendi inodzivirira ngura (yakadai sependi tsvuku yemutobvu) + topcoat;
Kunze: kupisa-kunyika galvanizing (kufukidza ≥85μm) kana kupfapfaidza fluorocarbon coating.
Chinyorwa Chekushongedza:
Sarudzo yetsvimbo yekuwedera: E43 series (yakadai seJ422);
Ndiro yakatetepa(≤6mm): hapana kudiwa kwekupisa kwekutanga, ndiro yakakora (>20mm): kupisa kwekutanga kwe100-150℃ kudzivirira kutsemuka.
