I-Q355NHD I-Weather Resistance Steel Plate Ehlanganiswe Isakhiwo Sensimbi I-Truss Bridge Main Girder

Insimbi yesakhiwo esimelana nesimo sezulu iyinsimbi evikela ukugqwala emkhathini, okungeyensimbi yesakhiwo esinengxubevange ephansi enamandla aphezulu.Ngokwezici zayo eziyinhloko, ihlukaniswe yaba insimbi yesakhiwo ephakeme ukumelana nesimo sezulu kanye nensimbi engamelana nesimo sezulu yesakhiwo esishiselwe.

Insimbi ye-Weathering iwuchungechunge lwensimbi ene-alloy ephansi phakathi kwensimbi evamile nensimbi engagqwali, kanye nochungechunge lwensimbi enengxubevange ephansi phakathi kwensimbi evamile nensimbi engagqwali, enezindleko eziphansi kanye nekhwalithi enhle.

Ukuhlukaniswa:
1. High weathering steel
Insimbi yesakhiwo sokumelana nesimo sezulu esiphezulu iwukwengeza inani elincane lekhopha, i-phosphorus, i-chromium, nezinto ze-nickel ensimbi ukuze kwakhe ungqimba oluvikelayo ebusweni beqoqo lensimbi ukuze kuthuthukiswe ukusebenza kwensimbi ngokumelene nokugqwala komkhathi.Ungakwazi futhi ukwengeza inani elincane le-molybdenum, i-niobium, izakhi ezifana ne-vanadium, i-titanium ne-zirconium zingacwenga okusanhlamvu, zithuthukise izakhiwo zensimbi, zithuthukise amandla kanye nokuqina kwensimbi, zehlise izinga lokushisa lokuguquka eliphukayo, futhi zenze kube ukumelana kangcono ne-brittle fracture.
2. Weathering steel for isakhiwo Welding
Izakhi ezengezwe ebangeni lensimbi, ngaphandle kwe-phosphorus, ngokuyisisekelo zifana nezinsimbi zesakhiwo ezimelene nesimo sezulu, futhi imisebenzi yazo iyafana futhi ithuthukisa ukusebenza kokushisela.

Izici:

Insimbi ye-Weathering inezici zokuqina, ukwelula kwepulasitiki, ukwakha, ukushisela nokusika, ukumelana nokugqoka, ukumelana nokushisa okuphezulu nokumelana nokukhathala kwensimbi ephezulu;ukumelana nesimo sezulu izikhathi ezingu-2-8 kune-carbon steel evamile, futhi ukusebenza kwe-coating kungu-1.5 we-carbon steel evamile.Izikhathi ezingu-10, ukusebenza kwe-coating izikhathi ezingu-1.5-10 kune-carbon steel evamile, ingasetshenziselwa ukugqoka okuncanyana, ukumboza okungenalutho noma ukugqoka okulula.Le nsimbi inezici zokungagqwali, ukumelana nokugqwala, ukuphila okunwetshiwe, ukunciphisa nokunciphisa ukusetshenziswa, ukonga abasebenzi nokonga amandla, okuzuzisa abakhiqizi bezingxenye nabasebenzisi.Insimbi yesimo sezulu inokumelana nokugqwala okungcono emkhathini.Izinsimbi zesimo sezulu zingancishiswa, zivezwe noma zidwetshwe kalula.Isistimu yensimbi ekwazi ukumelana nokugqwala, ukunwetshwa kwempilo, ukonga abasebenzi, ukunciphisa ukusetshenziswa nokuthuthukiswa kwayo kuyindlela entsha, ubuchwepheshe obusha kanye nenqubo entsha engahlanganiswa nensimbi yesimanje, ukuze iqhubeke nokuthuthuka nokusungula izinto ezintsha.Isistimu yensimbi.

Izinzuzo:

Insimbi yesimo sezulu yenziwe nge-carbon steel evamile enenani elincane lezinto ezimelana nokugqwala njengethusi ne-nickel.Inezici zamandla ensimbi, i-ductility, ukwakha, i-welding, i-abrasion, izinga lokushisa eliphezulu, ukukhathala, njll;ukumelana nesimo sezulu yi-2 ~ 8 yensimbi ye-carbon evamile Ukusebenza kwe-coating izikhathi ezingu-1.5 ~ 10 kune-carbon steel evamile, engasetshenziswa ekuhlanganiseni okuncanyana, okungenalutho noma okwenziwe lula.Insimbi inezici zokumelana nokugqwala, ukumelana nokugqwala nokuphila isikhathi eside kwezingxenye, ukunciphisa nokunciphisa ukusetshenziswa, kanye nezici zokonga umsebenzi nezonga amandla, ezizuzisa abakhiqizi bezingxenye nabasebenzisi.

Isicelo:

Ukusetshenziswa kwensimbi yesakhiwo sokumelana nesimo sezulu esiphezulu kungcono kunensimbi yokumelana nesimo sezulu yesakhiwo esishiselwe ngenxa yokumelana nokugqwala komkhathi.Isetshenziselwa ikakhulukazi ukubopha, i-riveting kanye nokushisela izingxenye zesakhiwo zezimoto, iziqukathi, izakhiwo, imibhoshongo nezinye izakhiwo.Uma isetshenziswa njengezingxenye zesakhiwo ezishiselwe, ubukhulu bensimbi akufanele bube bukhulu kuno-16mm.Ukusebenza kwe-welding yensimbi yesimo sezulu yesakhiwo esihlanganisiwe kungcono kunensimbi ephezulu yesimo sezulu, futhi isetshenziselwa ikakhulukazi izingxenye zesakhiwo ezishiselwe amabhuloho, izakhiwo nezinye izakhiwo.
