I-S355JOHiyindinganiso yezinto ezibonakalayo okungeyensimbi yesakhiwo se-alloy ephansi futhi isetshenziselwa ikakhulukazi ukwakhiwa kwezingxenye ezingenalutho ezakhiwe ngendlela ebandayo nezishisayo.Leli zinga lensimbi lisuselwe ku-EN 10219 ejwayelekile yase-Europe futhi lifaneleka ngokukhethekile ukwenziwa kwezingxenye ezinezigodi ezishiselwe ezakhiwe ngokubanda.
I-S355JOHingasetshenziselwa ukwakhiwa kwezinhlobo eziningi zamashubhu, okuhlanganisa amashubhu ashiselwe okuvunguzayo (SSAW), amashubhu angenamthungo (SMLS), kanye namashubhu ashiselwe ngomthungo oqondile (RW noma LSAW).
Incazelo ye-S355JOH
"S" imele insimbi yesakhiwo;I-"355" imele impahla enamandla okuvunwa okungenani angu-355 MPa, okuqinisekisa ukusimama okuhle kwesakhiwo;"
I-J0H" ibhekisela engxenyeni engenalutho eyakhiwe ngendlela ebandayo enamandla angu-27 J ezingeni lokushisa lokuhlola elingu-0°C.
I-S355JOH ukwakheka kwamakhemikhali
Ikhabhoni (C): 0.20% ubuningi.
I-Silicon (Si): 0.55% ubuningi.
I-Manganese (Mn): umkhawulo ongu-1.60%
I-Phosphorus (P): 0.035% ubuningi.
Isibabule (S): 0.035% ubuningi.
I-nitrogen (N): 0.009% ubuningi.
I-Aluminium (Al): 0.020% ubuncane (le mfuneko ayisebenzi uma insimbi iqukethe izinto ezanele zokubopha i-nitrogen)
Sicela uqaphele ukuthi ukwakheka kwamakhemikhali athile kungahluka kuye ngomkhiqizi kanye nokucaciswa komkhiqizo othile.Ngaphezu kwalokho, ezinye izakhi ze-alloying, njenge-vanadium, i-nickel, ithusi, njll., zingangezwa ngesikhathi senqubo yokukhiqiza ukuze kuthuthukiswe izakhiwo ezithile zensimbi, kodwa inani nohlobo lwalezi zakhi ezingeziwe kufanele zihambisane amazinga afanele.
I-S355JOH Mechanical Properties
Amandla amancane okukhiqiza okungenani angama-355 MPa;
Amanani wamandla e-Tensile 510 MPa kuya ku-680 MPa;
Ubude bayo obuncane ngokuvamile budingeka ukuba bube ngaphezu kwamaphesenti angu-20;
Kufanele kuqashelwe ukuthi ubude bungase buthintwe usayizi wesampula, ukwakheka, nezimo zokuhlola, ngakho-ke ezinhlelweni ezithile zobunjiniyela, kungase kudingeke ukuthi ubhekisele kumazinga anemininingwane noma uhlole umphakeli wezinto ezibonakalayo ukuze uthole idatha enembile.
I-S355JOH Ubukhulu Nokubekezelelana
Ukubekezelela Ububanzi Bangaphandle (D)
Kumadiamitha angaphandle angekho ngaphezulu kuka-168.3mm, ukubekezelelana kungu-±1% noma ±0.5mm, noma yikuphi okukhulu.
Ngobubanzi obungaphandle obukhulu kuno-168.3mm, ukubekezelela kungu-±1%.
Ukuqina Kwezindonga (T) Ukubekezelelana
Ukubekezelela ukushuba kodonga okusekelwe kusayizi othize kanye nebanga lokujiya kodonga (njengoba kukhonjisiwe etafuleni), ngokuvamile ku-± 10% noma ngaphezulu, ukuze kulawulwe kahle izinhlelo zokusebenza zokujiya udonga, kungase kudinge i-oda elikhethekile.
Ukubekezelela Ubude
Ukubekezelela ubude obujwayelekile (L) ngu -0/+50mm.
Ngobude obumisiwe, ukubekezelelana kuvame ukuba ±50mm.
ubude obuthile noma ubude obuqondile bungase bube nezidingo eziqinile zokubekezelela, okudingeka zinqunywe ngokubonisana nomkhiqizi ngesikhathi soku-oda.
Ukubekezelela Okungeziwe Kwezigaba Eziyisikwele nezingunxande
Izingxenye eziyisikwele nezingunxande zinokubekezelela irediyasi yekhona langaphandle engu-2T, lapho u-T ewugqinsi lodonga.
Ukubekezelela Umehluko We-Diagonal
Okungukuthi, inani eliphezulu lomehluko phakathi kobude bama-diagonal amabili wezigaba eziyisikwele nezingunxande, ngokuvamile alibi ngaphezu kuka-0.8% wobude obuphelele.
Ukubekezelela I-Engeli Elungile kanye Neziqu Ezisontekile
Ukubekezelela ubuqotho (okungukuthi, ukuma kwesigaba) kanye nokusonteka (okungukuthi, ukucaba kwesigaba) nakho kucaciswe ngokuningiliziwe endinganisweni ukuze kuqinisekiswe ukunemba kwesakhiwo nokubukeka kwayo yonke.
Kungenxa yokuzinikela kwethu ekwenzeni kahle kuyo yonke imininingwane yokukhiqiza, kuhlanganiswe nolwazi lwethu olujulile nolwazi embonini ukuthi sikwazi ukuzuza isikhundla esiphambili ekukhiqizeniI-S355JOHipayipi lensimbi.
Siyaqonda ukuthi yonke iphrojekthi inezidingo eziqinile ekusebenzeni kwezinto, ngakho-ke, asihlinzeki ngemikhiqizo kuphela kodwa futhi sihlinzeka ngezixazululo ezibanzi kumakhasimende ethu.Uma unezidingo zemikhiqizo yethu noma amasevisi noma unemibuzo, sicela ukhululeke ukuxhumana nathi.Ithimba lethu liqukethe ochwepheshe abanolwazi abakulungele ukukunikeza imininingwane enemininingwane yomkhiqizo, izixazululo ezenziwe ngokwezifiso, kanye nokwesekwa kochwepheshe.
