Cacisa Inhloso Nezimfuneko
Lapho ukhethaInsimbi ye-U-channel, umsebenzi wokuqala ukucacisa ukusetshenziswa kwawo okuqondile kanye nezidingo ezibalulekile:
Lokhu kuhlanganisa ukubala ngokunembile noma ukuhlola ubukhulu bomthwalo ewudingayo ukuze imelane nawo (umthwalo omile, umthwalo oguquguqukayo, umthelela, njll.), onquma ngokuqondile ukucaciswa nobukhulu (ubude, ububanzi bomlenze, ukujiya kokhalo) kanye nebanga lamandla wempahla; ukuqonda izimo zokusetshenziswa kwayo (ezifana nemishayo yesakhiwo/i-purlins yesakhiwo, amafreyimu emishini, izisekelo zezintambo zokuthutha, amashalofu noma imihlobiso), izimo ezihlukene zinokugcizelela okuhlukile kumandla, ukuqina, ukunemba nokubukeka; kucatshangelwa indawo okusetshenziswa kuyo (ngaphakathi/ngaphandle, noma ngabe kunomswakama, imidiya egqwalayo), enquma izidingo zokunqanda ukugqwala (njengokufaka ama-hot-dip galvanizing, ukupenda) noma ukuthi iyadingeka yini insimbi yesimo sezulu/insimbi engagqwali; ukucacisa indlela yokuxhuma (i-welding noma i-bolting), okuzothinta umklamo womlenze (indawo ye-welding flat noma izimbobo ezigodliwe ziyadingeka) kanye nezidingo ze-weldability ezibonakalayo; ngesikhathi esifanayo, kuyadingeka ukuqinisekisa imikhawulo yesayizi yendawo yokufaka (ubude, ubude, ububanzi) kanye nemithethonqubo ethile noma amazinga embonini okumele iphrojekthi ihambisane nawo ukuze kuqinisekiswe ukuthi izinto ezikhethiwe zihlangabezana nazo zonke izidingo zokuphepha nokusebenza.
Ukucaciswa Kwensimbi Yesiteshi, Ubukhulu kanye Nezinto Zokusebenza
1. Imininingwane
Izinga laseYurophuIsiteshi se-UPNamamodeli aqanjwe ngobude bezinkalo (iyunithi: mm). Banesiqephu esiphambanayo esimise okwe-U futhi amapharamitha angukhiye afaka:
Ubude besinqe (H): Ubude bubonke besiteshi. Ngokwesibonelo, ukuphakama okhalweni UPN240 kuyinto 240 mm.
Ububanzi bebhendi (B): Ububanzi be-flange. Isibonelo, i-UPN240 inebhendi engu-85 mm.
Ukujiya kwesinqe (d): Ukujiya kwewebhu. Isibonelo, i-UPN240 inokhalo oluyi-9.5 mm.
Ubukhulu bebhendi (t): Ubukhulu be-flange. Isibonelo, i-UPN240 inogqinsi lwebhendi engu-13 mm.
Isisindo sethiyori ngemitha: Isisindo ngobude beyunithi (kg/m). Isibonelo, i-UPN240 inesisindo esingu-33.2 kg/m.
Ukucaciswa Okujwayelekile (Amamodeli Angaphelele):
| imodeli | Ubude bokhalo (mm) | Ububanzi bomlenze (mm) | Ukuqina okhalweni (mm) | Ubukhulu bomlenze (mm) | Isisindo sethiyori imitha (kg/m) |
| I-UPN80 | 80 | 45 | 6 | 8 | 8.64 |
| I-UPN100 | 100 | 50 | 6 | 8.5 | 10.6 |
| I-UPN120 | 120 | 55 | 7 | 9 | 13.4 |
| I-UPN200 | 200 | 75 | 8.5 | 11.5 | 25.3 |
| I-UPN240 | 240 | 85 | 9.5 | 13 | 33.2 |
| I-UPN300 | 300 | 100 | 10 | 16 | 46.2 |
| I-UPN350 | 350 | 100 | 14 | 16 | 60.5 |
2. Uhlobo lwezinto
Izinto zensimbi zesiteshi se-UPN kufanele zihlangabezane nezinga le-EN 10025-2 laseYurophu. Izinketho ezijwayelekile zifaka:
(1) Izinto ezisetshenziswayo
I-S235JR: Amandla okukhiqiza ≥ 235MPa, izindleko eziphansi, ezifanele izakhiwo ezimile (ezifana nezisekelo zokukhanya).
I-S275JR: Amandla okukhiqiza ≥ 275MPa, amandla alinganiselayo nomnotho, asetshenziselwa amafreyimu okwakha ajwayelekile.
I-S355JR: Amandla okukhiqiza ≥ 355MPa, inketho yokuqala yokulayisha okuphezulu, ifanele izimo zengcindezi ephezulu njengemishini yamachweba nezisekelo zebhuloho. Amandla ayo aqinile afinyelela ku-470 ~ 630MPa, futhi inokuqina okuhle kwezinga lokushisa eliphansi.
(2) Izinto ezikhethekile
Insimbi enamandla amakhulu: njenge-S420/S460, esetshenziselwa izinto zamandla enuzi nezisekelo zemishini esindayo kakhulu (njenge-UPN350).
Insimbi yesimo sezulu: njenge-S355J0W, imelana nokugqwala komkhathi, ifanele amabhuloho angaphandle.
Insimbi engagqwali: isetshenziswa ezindaweni ezonakalisayo njengamakhemikhali nasolwandle, kodwa ngezindleko eziphezulu.
(3) Ukwelashwa kwendawo
Umnyama ogoqelwe oshisayo: indawo ezenzakalelayo, idinga ukwelashwa okulandelayo okunqanda ukugqwala.
I-hot-dip galvanizing: ungqimba oluwuthayela ≥ 60μm (njengensimbi yesiteshi yezisekelo zegalari yamapayipi), kuthuthukisa ukumelana nokugqwala.
3. Izincomo zokukhetha
Izimo ezinomthwalo omkhulu (njengama-port crane rails): Beka kuqala izinto ze-UPN300~UPN350 + S355JR ukuze uqinisekise ukugoba nokushesha ukumelana.
Indawo eyonakalisayo: Hlanganisa ne-hot-dip galvanizing noma sebenzisa ngokuqondile insimbi yesimo sezulu.
Izidingo ezingasindi: UPN80~UPN120 uchungechunge (imitha isisindo 8.6~13.4kg/m), ifanele izikebhe zamakhethini odongeni nezisekelo zamapayipi.
Qaphela: Lapho uthenga, kuyadingeka ukuthi uqinisekise umbiko wezinto ezibonakalayo (ngokuhambisana ne-EN 10025-2) kanye nokubekezelelana kobukhulu (EN 10060) ukuze uqinisekise ukuthobela iphrojekthi.
Iqembu Elinokwethenjelwa Lomkhiqizi Wesiteshi U-U-Royal
At Royal Group, singabalingani abaholayo emkhakheni wezohwebo wezinsimbi zezimboni zaseTianjin. Ngobungcweti nokuzibophezela ekubekeni phambili ikhwalithi, asizisunguli nje ngensimbi emise okwe-U, kodwa nakuyo yonke eminye imikhiqizo yethu.
Yonke imikhiqizo ehlinzekwa yi-Royal Group ingena inqubo yokuhlola ikhwalithi eqinile ukuze kuqinisekiswe ukuthi ihlangabezana noma idlula izindinganiso zekhwalithi ephezulu kakhulu. Lokhu kusisiza ukuthi sinikeze amakhasimende ethu imikhiqizo ethembekile nephephile elungele izinhlelo zokusebenza ezihlukahlukene.
Siyaqonda ukuthi isikhathi siwumgogodla kumakhasimende ethu, ngakho-ke, abasebenzi bethu nenqwaba yezimoto zihlala zilungele ukuletha izimpahla. Ngokuqinisekisa isivinini nokugcina isikhathi, sisiza amakhasimende ethu onge isikhathi futhi athuthukise izinqubo zawo zokwakha.
I-Royal Group ayilethi nje kuphela ukuzethemba ngekhwalithi yomkhiqizo kanye nenani, kodwa futhi ibonisa ubuqotho ebudlelwaneni bethu bamakhasimende. Asinikezi nje kuphela izinhlobonhlobo zensimbi emise okwe-U, kodwa futhi neminye imikhiqizo ehlukahlukene, njengensimbi emise okwe-H, insimbi emise okwe-I, nensimbi emise okwe-C, ukuze kuhlangatshezwane nezidingo ezahlukahlukene zamakhasimende ezweni lonke.
Wonke ama-oda afakwe neRoyal Group ayahlolwa ngaphambi kokukhokha. Amakhasimende anelungelo lokuhlola imikhiqizo yawo ngaphambi kokukhokha ukuze aqinisekise ukwaneliseka kanye nekhwalithi yomkhiqizo.a
