I-Q355NHD Ipleyiti yentsimbi yokuNxhathisa iMozulu eDityanisiweyo yeSakhiwo seSimbi seTruss iBhulorho eMain

Intsimbi yolwakhiwo olumelana nemozulu yintsimbi enganyangekiyo kwi-atmospheric, eyeyentsimbi yolwakhiwo olukwialloyi esezantsi yokuqina.Ngokweempawu zayo eziphambili, ihlulwe ibe yintsimbi yesakhiwo esinemozulu ephezulu kunye nentsimbi echasene nemozulu kwisakhiwo esidibeneyo.

I-Weathering steel yingqokelela yentsimbi ephantsi-i-alloy ephakathi kwentsimbi eqhelekileyo kunye nentsimbi engenasici, kunye noluhlu lwentsimbi ephantsi-i-alloy phakathi kwentsimbi eqhelekileyo kunye nensimbi engenasici, enexabiso eliphantsi kunye nomgangatho omhle.

Ukuhlelwa:
1. Intsimbi ephezulu yemozulu
Ukumelana nemozulu ephezulu yentsimbi yesakhiwo kukongeza inani elincinci lobhedu, i-phosphorus, i-chromium, kunye ne-nickel element kwintsimbi ukwenza umaleko okhuselayo kumphezulu we-collective yesinyithi ukuphucula ukusebenza kwentsimbi ngokuchasene nokuhlwa kwe-atmospheric.Ungongeza kwakhona inani elincinci le-molybdenum, i-niobium, i-Elements ezifana ne-vanadium, i-titanium kunye ne-zirconium inokucoca iinkozo, iphucule iipropathi zentsimbi, iphucule amandla kunye nokuqina kwentsimbi, ukunciphisa ubushushu benguqu enqabileyo, kwaye iyenze ibe nayo. ukumelana ngcono ukwaphuka brittle.
2. Weathering steel kwisakhiwo welding
Izinto ezongeziweyo kwibakala lensimbi, ngaphandle kwe-phosphorus, zifana ngokusisiseko nezinsimbi zesakhiwo ezichasene nemozulu, kwaye imisebenzi yazo iyafana kwaye iphucula ukusebenza kwe-welding.

Iimbonakalo:

I-Weathering steel ineempawu zokuqina, ukunweba kweplastiki, ukubumba, i-welding kunye nokusika, ukuxhathisa ukunxiba, ukumelana nobushushu obuphezulu kunye nokumelana nokudinwa kwensimbi ephezulu;ukuchasana kwemozulu ngama-2-8 amaxesha entsimbi eqhelekileyo ye-carbon, kunye nokusebenza kokugquma yi-1.5 yentsimbi yekhabhoni eqhelekileyo.Amaxesha angama-10, ukusebenza kwe-coating yi-1.5-10 yamaxesha e-carbon steel eqhelekileyo, ingasetyenziselwa ukugquma okuncinci, ukugquma okungenanto okanye i-coating elula.Le ntsimbi ineempawu zokuchasana nokugqwala, ukuxhathisa ukubola, ubomi obude, ukunciphisa kunye nokunciphisa ukusetyenziswa, ukugcinwa kwabasebenzi kunye nokugcina amandla, okuxhamla abavelisi bamacandelo kunye nabasebenzisi.I-Weathering steel inokumelana nokugqwesa okungcono kwi-atmosfera.Intsimbi yemozulu inokucuthwa, iveze okanye ipeyintwe ngokulula.Inkqubo yensimbi enokumelana nokubola, ukwandiswa kobomi, ukugcinwa kwabasebenzi, ukunciphisa ukusetyenziswa kunye nokuphucula kwakhona yindlela entsha, iteknoloji entsha kunye nenkqubo entsha enokuthi idibaniswe kwi-metallurgy yanamhlanje, ukuze iqhubeke nokuphuhlisa kunye nokuvuselela.Inkqubo yentsimbi.

Izinto eziluncedo:

I-Weathering steel yenziwe ngentsimbi yekhabhoni eqhelekileyo kunye nenani elincinci lezinto ezinganyangekiyo kwi-corrosion ezifana nobhedu kunye ne-nickel.Ineempawu zamandla ensimbi, i-ductility, ukubunjwa, i-welding, i-abrasion, ukushisa okuphezulu, ukukhathala, njl.;ukumelana nemozulu yi-2 ~ 8 ye-carbon steel eqhelekileyo Ukusebenza kwe-coating yi-1.5 ~ 10 amaxesha e-carbon steel eqhelekileyo, enokusetyenziswa kwi-coating encinci, engenanto okanye elula.Intsimbi ineempawu zokumelana nokugqwala, ukuxhathisa ukubola kunye nexesha elide lamacandelo, ukunciphisa kunye nokunciphisa ukusetyenziswa, kunye neempawu zokulondoloza umsebenzi kunye nokugcina amandla, ezixhamla abavelisi bamacandelo kunye nabasebenzisi.

Isicelo:

Ukusetyenziswa kwentsimbi yolwakhiwo oluphezulu lwemozulu lungcono kunentsimbi yokumelana nemozulu kwisakhiwo esidityanisiweyo ngenxa yokumelana ne-atmospheric corrosion.Isetyenziselwa ikakhulu ukwenza iibholiti, iiriveting kunye nokuwelda iinxalenye zezakhiwo zezithuthi, izikhongozeli, izakhiwo, iinqaba kunye nezinye izakhiwo.Xa isetyenziswe njengeendawo ezidityanisiweyo zesakhiwo, ubukhulu bentsimbi akufanele bube bukhulu kune-16mm.Ukusebenza kwe-welding ye-weathering ye-weathering ye-welded structure ingcono kune-high weathering steel, kwaye isetyenziselwa ubukhulu becala kwiindawo ezidibeneyo zesakhiwo kwiibhulorho, izakhiwo kunye nezinye izakhiwo.
