1. Chiyambi: Giredi Yofanana, DNA Yosiyana
Muzofotokozera za chitsulo chomangidwa,S355J2Hndi chinthu chofunikira kwambiri kwamagawo opanda kanthuKomabe, imawoneka pansi pa miyezo iwiri yosiyana yopanga:EN 10210ndiEN 10219Ngakhale kuti dzina lakuti "S355J2H" nthawi zambiri limanyenga ogula kuti aziganiza kuti ndi ofanana, njira yopangira—ndipo motero magwiridwe antchito—amasiyana kwambiri.
Nkhaniyi ikuyerekeza EN 10210 S355J2H (Yomalizidwa ndi Moto) ndi EN 10219 S355J2H (Yopangidwa ndi Cold) kuti ifotokoze kusiyana kwawo kwa makina, mawonekedwe, ndi kuyenerera kwa ntchito.
2. Kusiyana Kwakukulu: Njira Yopangira
EN 10210 - Yotentha Yomalizidwa (S355J2H)
Zigawo zomwe zili pansi pa EN 10210 zimapangidwa pa kutentha kokwera (nthawi zambiri pamwamba pa kutentha kwa recrystallization). Njira iyi ya "Hot Finished" imachepetsa kupsinjika kwamkati komwe kumachitika panthawi yopanga. Mkati mwa EN 10210, S355J2H nthawi zambiri imapangidwa kudzera mu njira ya Stress Relieved (yotenthetsera pansi pa 850°C) kapena njira ya Fully Normalized (yotenthetsera pamwamba pa ~850°C kuti isinthe kapangidwe ka tirigu). Machubu okhazikika bwino amapereka ductility yabwino komanso kufanana.
EN 10219 - Zopangidwa ndi Zipatso Zozizira (S355J2H)
Zigawo zomwe zili pansi pa EN 10219 zimapangidwa kutentha kwa chipinda kuchokera ku coil yachitsulo kapena mbale. Chitsulocho chimapindidwa kenako chimalumikizidwa (nthawi zambiri ERW kapena SAW). Kugwira ntchito kozizira kumeneku kumalimbitsa chitsulocho, makamaka pamapindo ndi m'makona, ndikutseka mphamvu zambiri zotsalira.
3. Kuyerekeza kwa Mafotokozedwe Aukadaulo (S355J2H)
Ngakhale malire a kapangidwe ka mankhwala ali ofanana, magwiridwe antchito a makina ndi kulekerera kovomerezeka kumasinthasintha chifukwa cha njira yopangira.
| Katundu | EN 10210-1(Yotentha Kwambiri) | EN 10219-1(Yopangidwa ndi Zipatso Zozizira) |
| Kutentha Kwambiri | Pamwamba pa Kubwezeretsanso (Kutentha) | Kutentha kwa Malo Ozungulira / Kuzizira kwa Chipinda (Kuzizira) |
| Mphamvu Yotulutsa (ReH) (T ≤ 16mm) | ≥ 355 MPa | ≥ 355 MPa |
| Mphamvu Yokoka (Rm) (3mm ≤ T ≤ 40mm) | 470 – 630 MPa | 470 – 630 MPa *(Dziwani: Mndandanda wa EN10219 wa 490-630 wa T<3mm)* |
| Kutalikitsa | Osachepera 22% (Kusinthasintha kwakukulu chifukwa cha kutentha) | Osachepera 20% (Kutsika chifukwa cha kuuma kwa ntchito) |
| Kulimba kwa Impact (KV) | 27J @ -20°C | 27J @ -20°C |
| Kupsinjika Kotsalira | Yotsika (Yochepa ndi kutentha) | Wapamwamba (Wotsekedwa mu mawonekedwe) |
| Pakona Yozungulira (SHS/RHS) | < 2T (Yolimba, yakuthwa) | 1.6T ~ 3.6T (Utali wozungulira waukulu) |
4. Kusiyana kwa Mawonekedwe ndi Magawo
Zotsatira za "Kuthina" (Kupsinjika Kotsalira): Zigawo zozizira (EN 10219) zimakhala ndi chizolowezi chachilengedwe "chobwerera m'mbuyo" kapena "kuthina" zikadulidwa chifukwa cha mphamvu yotsala yosungidwa. Zigawo zotentha (EN 10210) zimakhalabe zokhazikika muyeso zikadulidwa.
Makona: Pa Magawo Okhala ndi Mabowo Aakulu ndi Amakona Ang'onoang'ono (SHS/RHS), EN 10219 imalola kuti pakhale ma radius a ngodya mpaka kuwirikiza katatu kuposa makulidwe a khoma (T), zomwe zimapangitsa kuti pakhale ma ngodya ozungulira kwambiri. Magawo a EN 10210 otentha (makamaka abwinobwino) amakhala ndi ma radius akuthwa kwambiri (nthawi zambiri <2T), zomwe zimapangitsa kuti pakhale malo osalala komanso ogwira ntchito bwino.
Kukhuthala kwa Khoma: EN 10210 nthawi zambiri imapereka kulekerera makulidwe kolimba poyerekeza ndi EN 10219.
5. Ndi iti yomwe muyenera kusankha?
SankhaniEN 10210-1 S355J2Hngati:
Ntchito zofunika kwambiri pa kapangidwe kake: Milatho, ma crane booms, malo ozungulira zivomerezi, kapena nsanja za m'mphepete mwa nyanja.
Kukana Kutopa Kwambiri: Kuwotcherera kapena kuyika zinthu mosinthasintha kumafuna kuti zinthuzo zikhale ndi mphamvu zochepa kuti ming'alu isayambe.
Zofunikira Zokongoletsa/Zolondola: Mufunika ngodya zolimba komanso kulunjika kodziwikiratu kuti mupange zitsulo zowonekera bwino.
Kutentha: Ngati mukufuna kupindika kapena kupanga malekezero a kutentha kwambiri, zinthu zomwe zasinthidwa zimakhala bwino kwambiri.
Sankhani EN 10219-1 S355J2H ngati:
Kugwiritsa ntchito bwino ndalama: Kupanga zinthu zozizira nthawi zambiri kumakhala kotsika mtengo komanso kopepuka pamlingo wocheperako.
Kupanga zinthu wamba: Nyumba zazitali, pansi pa mezzanine, mizati ya mpanda, kapena zida zaulimi komwe kulibe vuto lalikulu.
Kupezeka: Ndi chubu "chokhazikika" chomwe chimapezeka kwambiri mwa ogulitsa ambiri padziko lonse lapansi.
6. Chenjezo Lofunika Kwambiri pa "S355J2H"
Samalani: Si machubu onse a EN 10210 S355J2H omwe amapangidwa mofanana.
Opanga amatha kupanga machubu a EN 10210 pogwiritsa ntchito "Kuchepetsa Kupsinjika" kapena "Kukhazikika Kwathunthu."
Standard S355J2H (Yochepetsa Kupsinjika): Imakwaniritsa muyezo koma imakhalabe ndi kupsinjika pang'ono. Ndi yotsika mtengo.
S355NH (Yokhazikika): Giredi yeniyeni pansi pa EN 10210 yomwe imafuna kukhazikika kwathunthu (kutentha kwambiri). Ichi ndi chinthu chabwino kwambiri chowotcherera.
Ngati mukufuna kusinthasintha kwakukulu komanso kusakhala ndi mphamvu yotsalira pakuwotcherera, sinthani spec yanu kukhala EN 10210 S355NH m'malo mwa J2H wamba.
