Zithunzi za S235JR

S235JR ndi chitsulo chosapanga dzimbiri ku Europe chofanana ndi muyezo wadziko lonse Q235B, womwe ndi chitsulo chopangidwa ndi kaboni chokhala ndi mpweya wochepa. Amagwiritsidwa ntchito powotcherera, ma bolting ndi ma riveting.

Carbon structural steel ndi mtundu wa carbon steel. Mpweya wa carbon ndi pafupifupi 0.05% ~ 0.70%, ndipo ena amatha kufika 0.90%. Iwo akhoza kugawidwa mu wamba mpweya structural zitsulo ndi apamwamba mpweya structural zitsulo. Amagwiritsidwa ntchito kwambiri mu njanji, mlatho, ntchito zosiyanasiyana zomanga, kupanga zigawo zosiyanasiyana zazitsulo zomwe zimanyamula katundu wosasunthika, mbali zosafunika zamakina ndi ma weldments ambiri omwe safuna chithandizo cha kutentha.

Gulu lachitsulo la S235JR likuwonetsa

"S": European muyezo wamba mpweya structural zitsulo;

"235": mphamvu zokolola ndi 235, unit: MPa;

"JR": kukhudza kutentha kwabwinobwino

3. S235JR zitsulo mbale mkulu muyezo: EN10025 muyezo

4. Mkhalidwe wobweretsera wa mbale yachitsulo ya S235JR: kugudubuza kotentha, kugwedezeka koyendetsedwa, normalizing, etc. Mkhalidwe woperekera ukhoza kutchulidwanso malinga ndi zofunikira zamakono.

5. S235JR chitsulo mbale makulidwe malangizo ntchito zofunika: Z15, Z25, Z35.

Kusanthula kwa Chemicals kwa mbale yachitsulo ya S235JR

S235JR Chemical:

S235JR mbale yachitsulo ya carbon C: ≤ 0.17

S235JR zitsulo mbale silikoni zili Si: ≤ 0.35

S235JR zitsulo mbale manganese zili Mn: ≤ 0.65

Phosphorus zomwe zili mu mbale yachitsulo ya S235JR P: ≤ 0.030

S235JR zitsulo mbale sulfure zili S: ≤ 0.030

3, makina katundu wa S235JR zitsulo mbale

makulidwe 8-420mm:

Kutulutsa mphamvu MPa: ≥ 225

Mphamvu zolimba MPa: 360 ~ 510

Elongation%: ≥ 18

4, S235JR zitsulo kupanga mbale ndondomeko:

Njira yopangira: kusungunula ng'anjo yamagetsi → LF/VD ng'anjo yamagetsi → kuponyera → kuyeretsa ingot → kutentha kwa ingot → kugudubuza mbale → kumaliza → kudula zitsanzo → kuyang'anira ntchito → malo osungiramo katundu

5, S235JR zitsulo mbale kukula makulidwe oyamba

8-50mm * 1600-2200mm * 6000-10000mm

50-100mm * 1600-2200mm * 6000-12000mm

100-200mm * 2000-3000mm * 10000-14000mm

200-350mm * 2200-4020mm * 10000-18800mm

Magulu apamwamba
Pamwamba wamba (FA)
The pickled pamwamba amaloledwa kukhala ndi zolakwika pang'ono ndi m'deralo monga maenje, mano, zokanda, etc. amene kuya (kapena kutalika) si upambana theka la makulidwe kulolerana kwa mbale zitsulo, koma osachepera wololeka makulidwe a mbale zitsulo ndi Mzere wachitsulo udzatsimikiziridwa.
Pamwambamwamba (FB)
The pickling pamwamba amaloledwa kukhala ndi zilema m'deralo zimene sizimakhudza formability, monga zokanda pang'ono, indentations pang'ono, maenje pang'ono, zodzigudubuza pang'ono zizindikiro ndi kusiyana mitundu.

Kugwiritsa ntchito zinthu
Amagwiritsidwa ntchito kwambiri pomanga, mlatho, sitima, zida zamagalimoto, kupanga zida zosiyanasiyana, zida zodulira, nkhungu ndi zida zoyezera.
