Nkhani - "Zozungulira" mu Carbon Steel Plate

Mpweya wachitsulo wa carbon ndi imodzi mwamagulu ofunikira kwambiri azitsulo. Zimakhazikitsidwa ndi chitsulo, chokhala ndi mpweya wapakati pa 0.0218% -2.11% (muyezo wamafakitale), ndipo mulibe kapena pang'ono zinthu zophatikizika. Malinga ndi zomwe zili mu kaboni, zitha kugawidwa m'magulu awiri:
Chitsulo chochepa cha carbon(C≤0.25%): kulimba kwabwino, kosavuta kukonza, Q235 ndi ya gulu ili;
Chitsulo chapakati cha carbon(0.25%
High carbon steel(C> 0.6%): kuuma kwambiri komanso kuphulika kwakukulu.

Q235 mpweya zitsulo: tanthauzo ndi pakati magawo (GB/T 700-2006 muyezo)

Kupanga	C	Si	Mn	P	S
Zamkatimu	≤0.22%	≤0.35%	≤1.4%	≤0.045%	≤0.045%

Makaniko katundu:
Zokolola mphamvu: ≥235MPa (kukhuthala ≤16mm)
Mphamvu yamphamvu: 375-500MPa
Elongation: ≥26% (kukhuthala ≤16mm)

Zofunika ndi Magwiridwe

Zofunika:Zida wamba zikuphatikizapoGR.B, X42, X46, X52, X56, X60, X65, X70, ndi zina.

Makhalidwe Antchito
Mphamvu Zapamwamba: Kutha kupirira kuthamanga kwakukulu kopangidwa ndi madzi monga mafuta ndi gasi wachilengedwe panthawi yoyendetsa.
Kulimba Kwambiri: Sizophweka kuthyoka pamene zikhudzidwa ndi zochitika zakunja kapena kusintha kwa chilengedwe, kuonetsetsa kuti payipi ikugwira ntchito bwino.
Kukaniza Kwabwino kwa Corrosion: Malinga ndi malo osiyanasiyana ogwiritsira ntchito komanso media, kusankha zida zoyenera ndi njira zochizira pamwamba kumatha kukana dzimbiri ndikukulitsa moyo wautumiki wa payipi.

Makhalidwe a "hexagonal warrior" a Q235

Kuchita Kwabwino Kwambiri Kwambiri
Weldability: Palibe kutentha koyenera, koyenera kuwotcherera kwa arc, kuwotcherera kwa gasi ndi njira zina (monga kumanga chitsulo chowotcherera);
Cold Formability: Itha kupindika ndikudindidwa mosavuta (chitsanzo: chipolopolo cha bokosi logawa, njira yolowera mpweya);
Kuthekera: Ntchito yokhazikika pansi pa kudula kothamanga (makina a makina).
Comprehensive Mechanical Balance

Mphamvu vs Kulimba: 235MPa zokolola mphamvu zimatengera kunyamula katundu ndi kukana mphamvu (poyerekeza ndi Q195's 195MPa);
Kusinthasintha kwa Chithandizo Chapamwamba: Yosavuta kuyimitsa ndikupopera utoto (monga zotchingira, zitsulo zopepuka).
Kuchita Bwino Kwambiri Pazachuma
Mtengo uli pafupi ndi 15% -20% wotsika kuposa wachitsulo chochepa cha alloy champhamvu kwambiri (monga Q345), choyenera kugwiritsidwa ntchito kwakukulu.
High Degree of Standardization
makulidwe Common: 3-50mm (katundu okwanira, kuchepetsa makonda mkombero);
Miyezo yoyendetsera: GB/T 700 (yapakhomo), ASTM A36 (yofanana padziko lonse lapansi).

Gulani ndi Kugwiritsa Ntchito "Avoidance Guide"

Chizindikiritso cha Ubwino:
Maonekedwe: palibe ming'alu, zipsera, makutu (GB / T 709 mbale mawonekedwe muyezo);
Chitsimikizo: Yang'anani kapangidwe kake, makina amakina ndi lipoti lozindikira zolakwika (kuzindikira zolakwika za UT ndikofunikira pazigawo zofunika kwambiri).
Anti-corrosion strategy:
M'nyumba: utoto wotsutsa dzimbiri (monga utoto wofiira wofiira) + topcoat;
Panja: otentha-kuviika galvanizing (≥85μm ≥85μm) kapena kupopera fluorocarbon ❖ kuyanika.
Welding Note:
Kusankha ndodo zowotcherera: E43 mndandanda (monga J422);
Mbale woonda(≤6mm): palibe preheating chofunika, mbale wandiweyani (> 20mm): preheat 100-150 ℃ kuteteza ming'alu.
