S355JOHiyindinganiso yezinto ezibonakalayo engeyezinsimbi ezakhiwe nge-alloy ephansi futhi isetshenziswa kakhulu ekwenziweni kwezingxenye ezingenalutho ezakhiweni ezibandayo nezishisayo. Le ndinganiso yensimbi isekelwe ku-European standard EN 10219 futhi ifaneleka kakhulu ekwenziweni kwezingxenye ezingenalutho ezakhiweni ezibandayo ezihlanganisiwe.
S355JOHingasetshenziswa ekwenzeni izinhlobo eziningi zamashubhu, okuhlanganisa amashubhu ahlanganisiwe ajikelezayo (SSAW), amashubhu angenamthungo (SMLS), kanye namashubhu ahlanganisiwe aqondile (ERW noma LSAW).
Incazelo ye-S355JOH
"S" imele insimbi yokwakha; "355" imele izinto ezinamandla okukhiqiza okungenani angu-355 MPa, okuqinisekisa ukuzinza okuhle kwesakhiwo; "
I-J0H" ibhekisela engxenyeni engenalutho eyakhiwe ngokubandayo enamandla okushaya angu-27 J ekushiseni kokuhlolwa okungu-0°C.
Ukwakheka kwamakhemikhali kwe-S355JOH
Ikhabhoni (C): 0.20% ubuningi.
I-Silicon (Si): 0.55% ubuningi.
I-Manganese (Mn): ubuningi obungu-1.60%
I-Phosphorus (P): 0.035% ubuningi.
I-Sulfur (S): 0.035% ubuningi.
I-nitrogen (N): 0.009% ubuningi.
I-Aluminium (Al): ubuncane obungu-0.020% (le mfuneko ayisebenzi uma insimbi iqukethe izinto ezanele zokubopha i-nitrogen)
Sicela uqaphele ukuthi ukwakheka kwamakhemikhali athile kungahluka kuye ngomkhiqizi kanye nemininingwane ethile yomkhiqizo. Ngaphezu kwalokho, ezinye izinto zokuhlanganisa, njenge-vanadium, i-nickel, ithusi, njll., zingangezwa ngesikhathi senqubo yokukhiqiza ukuze kuthuthukiswe izakhiwo ezithile zensimbi, kodwa inani nohlobo lwalezi zinto ezengeziwe kufanele kuhambisane nezindinganiso ezifanele.
Izakhiwo Zemishini ze-S355JOH
Amandla okukhiqiza okungenani angu-355 MPa;
Amandla okunamathela asukela ku-510 MPa kuya ku-680 MPa;
Ukwandiswa kwayo okuncane ngokuvamile kudingeka kube ngaphezu kwamaphesenti angama-20;
Kufanele kuqashelwe ukuthi ukunwebeka kungathinteka usayizi wesampula, ukuma, kanye nezimo zokuhlola, ngakho-ke ezicelweni ezithile zobunjiniyela, kungadingeka ukubhekisela ezindinganisweni ezinemininingwane noma uhlole nomhlinzeki wezinto ukuze uthole idatha enembile.
Ubukhulu kanye nokubekezelelana kwe-S355JOH
Ukubekezelelana Kobubanzi Bangaphandle (D)
Kumadayamitha angaphandle angengaphezu kuka-168.3mm, ukubekezelelana kungu-±1% noma ±0.5mm, noma yikuphi okukhulu.
Ngobubanzi bangaphandle obungaphezu kuka-168.3mm, ukubekezelelana kungu-±1%.
Ukujiya Kodonga (T) Ukubekezelelana
Ukubekezelela ukujiya kodonga okusekelwe kusayizi othize kanye nezinga lokujiya kodonga (njengoba kuboniswe kuthebula), ngokuvamile ku-± 10% noma ngaphezulu, ukuze kulawulwe ngokunembile ukusetshenziswa kokujiya kodonga, kungadinga i-oda elikhethekile.
Ukubekezelela Ubude
Ukubekezelela ubude obujwayelekile (L) kungu--0/+50mm.
Ngobude obungaguquki, ukubekezelelana kuvame ukuba ngu-±50mm.
ubude obuthile noma ubude obuqondile bungaba nezidingo zokubekezelelana okuqinile, okudingeka kunqunywe ngokubonisana nomenzi ngesikhathi soku-oda.
Ukubekezelelana Okungeziwe Kwezingxenye Eziyisikwele Nezingunxande
Izingxenye eziyisikwele nezingunxande zinokubekezelela irediyasi yangaphandle yekhoneni elingu-2T, lapho u-T ewubukhulu bodonga.
Ukubekezelela Umehluko Oqondile
Okusho ukuthi, inani eliphakeme lomehluko phakathi kobude bezinhlangothi ezimbili eziqondile zezingxenye zesikwele nezingunxande, ngokuvamile alidluli ku-0.8% wobude obuphelele.
Ukubekezelela i-Engela Engakwesokudla kanye neDigri Yokujika
Ukubekezelelana kokuqonda (okungukuthi, ukuma kwesigaba) kanye nokusonta (okungukuthi, ukuba yisicaba kwesigaba) nakho kuchazwe ngokuningiliziwe endinganisweni ukuqinisekisa ukunemba kwesakhiwo kanye nokubukeka kwayo yonke indawo.
Kungenxa yokuzinikela kwethu ekwenzeni kahle kakhulu kuyo yonke imininingwane yokukhiqiza, kuhlanganiswe nolwazi lwethu olujulile kanye nokuhlangenwe nakho embonini ukuthi sikwazi ukufeza isikhundla esiphambili ekukhiqizeniS355JOHipayipi lensimbi.
Siyaqonda ukuthi yonke iphrojekthi inezidingo eziqinile ekusebenzeni kwezinto zokwakha, ngakho-ke, asigcini nje ngokuhlinzeka ngemikhiqizo kodwa futhi sihlinzeka ngezixazululo eziphelele kumakhasimende ethu. Uma unezidingo zemikhiqizo noma izinsizakalo zethu noma unemibuzo eminye, sicela ukhululeke ukuxhumana nathi. Ithimba lethu liqukethe ochwepheshe abanolwazi abakulungele ukukunikeza ulwazi oluningiliziwe lomkhiqizo, izixazululo ezenziwe ngokwezifiso, kanye nokusekelwa kobuchwepheshe bochwepheshe.
amathegi: en 10219, s33joh, imibuzo evame ukubuzwa, abahlinzeki, abakhiqizi, amafektri, abathengisi bamasheya, izinkampani, ukuthengisa ngobuningi, ukuthenga, intengo, ikhotheshini, inqwaba, okuthengiswayo, izindleko.
