I-Q345B Square Tube
Ishubhu lesikwele esingu-Q345B, ishubhu lesikwele esingu-16Mn, ishubhu lesikwele esingu-Q345B, ishubhu lesikwele, ishubhu lesikwele esingunxande, ishubhu lesikwele esingenamthungo, ishubhu lesikwele lensimbi engenasici, ishubhu lesikwele elingunxande, ishubhu lesikwele esingu-q345b, ishubhu lesikwele esinobubanzi obukhulu, ishubhu lesikwele esingu-Q345C, isikwele sensimbi engagqwali. Amapayipi ensimbi angunxande, amapayipi ensimbi angenamthungo angunxande neminye imikhiqizo yamapayipi ayisikwele.
Ishubhu yesikwele ye-Q345B ikhiqizwa ngokwezinga likazwelonke le-GBT 6728-2002 lensimbi yesigaba esingenalutho esakhiwe ngendlela ebandayo ngosayizi, umumo, isisindo kanye nokuchezuka okuvumelekile kwesakhiwo. Yenziwe nge-Q345B strip steel ngemuva kokucubungula nokugingqika. Ishubhu yesikwele ye-Q345B yenziwe ngezinto ezisetshenziswayo ze-Q345B (ingxubevange ephansi), ehluke kakhulu kushubhu yesikwele esivamile sempahla eluhlaza (Q195, Q215, Q235). Ngokuvamile, i-Q345B strip steel (i-alloy ephansi) ayipakishiwe. , Isicaba, i-crimped, i-welded ukuze yenze ithubhu eliyindilinga, bese igoqa ibe yithubhu yesikwele isuka eshubhu eliyindilinga bese inqunywa ubude obudingekayo. Ubude obujwayelekile ngamamitha ayi-6, kanti inani elikhulu lamamitha ayi-12 lingacutshungulwa ngokuya ngezidingo zamakhasimende. Ngokuvamile, usayizi omncane uyizingcezu ezingu-50 iphakethe ngalinye, futhi usayizi omkhulu izingcezu ezi-4 ngayinye futhi isisindo silawulwa cishe amathani amathathu. Amashubhu ayisikwele e-Q345B iningi lawo angu-80MM*80MM-500MM*500MM ngokucaciswa okukhulu esitokweni, kanti ukujiya kungu-3MM-16MM.
Ishubhu yesikwele ye-Q345B ayinamthungo futhi ishiselwe
I-Q345B ithubhu yesikwele engenamthungo yakhiwa ngokukhipha ishubhu eliyindilinga elingenamthungo le-Q345B.
Q345B square tube plasticity
I-Plasticity ibhekisela ekhonweni lezinto zensimbi ukukhiqiza ukuguqulwa kwepulasitiki (ukuguqulwa okuhlala njalo) ngaphandle kokulimala ngaphansi komthwalo.
Q345B ubulukhuni beshubhu yesikwele
Ukuqina kuyisilinganiso sokuqina kwezinto zensimbi. Indlela evame ukusetshenziswa kakhulu yokulinganisa ubulukhuni ekukhiqizeni iyindlela yobulukhuni bokungena, esebenzisa i-indenter yomumo othile wejometri ukuze ucindezele ebusweni bensimbi ukuze ihlolwe ngaphansi komthwalo othile, futhi inani lokuqina linqunywa ngokusho izinga lokuhlehlisa.
Izindlela ezivame ukusetshenziswa zihlanganisa ukuqina kwe-Brinell (HB), ukuqina kwe-Rockwell (HRA, HRB, HRC) kanye nokuqina kwe-Vickers (HV).
Ishubhu lesikwele le-Q345B ishubhu lensimbi eliyisikwele elingenalutho elikhanyayo elinezindonga ezincane, elaziwa nangokuthi ingxenye yokugoba efrijini. Kuyinsimbi yesigaba esinomumo oyisikwele esiphambanayo nosayizi owenziwe ngomugqa ogoqekayo we-Q345B ogoqwa oshisayo noma ogoqekayo noma ikhoyili njengento eyisisekelo, eyakhiwe ngokugoba okubandayo bese ishiselwa nge-welding ephezulu kakhulu. Ngaphezu kokuqina kodonga lweshubhu yesikwele esishisayo esigoqiwe, ubukhulu bekhona kanye nokuqina komphetho kufinyelele noma kudlule ngisho nezinga lokumelana elishiselwe ishubhu lesikwele elakheke ngokubanda.
Q345B ukusetshenziswa kweshubhu yesikwele
Amapayipi ayisikwele e-Q345B ngokuvamile asetshenziswa ekwakheni, ukukhiqizwa kwemishini, amaphrojekthi wokwakha insimbi, ukwakhiwa kwemikhumbi, ukusekelwa kwamandla elanga, ubunjiniyela besakhiwo sensimbi, ubunjiniyela bamandla, izitshalo zamandla, imishini yezolimo neyamakhemikhali, izindonga zamakhethini ezingilazi, i-chassis yemoto, izikhumulo zezindiza, njll.
Q345B isikwele ipayipi igatsha isisindo formula wokubala: 4 izinhlangothi wanezela * ukujiya * 0.00785 * ubude
I-Q345B ipayipi elingunxande lokusekela isisindo sefomula yokubala: (ubude obuhlangothini + ubude obuhlangothini) * 2 * 0.00785 * ukujiya kodonga * ubude
