Q345B Square Tube
Q345B ityhubhu yesikwere, ityhubhu yesikwere ye-16Mn, ityhubhu yesikwere ye-Q345B, ityhubhu yesikwere, ityhubhu yesikwere, ityhubhu yesikwere engenamthungo, ityhubhu yesikwere yentsimbi, ityhubhu yesikwere esikwere, ityhubhu ye-q345b yesikwere, ityhubhu enkulu enodonga olungqingqwa, ityhubhu ye-Q345C yesikwere, isikwere sensimbi engenasici. Imibhobho yentsimbi yoxande, ingenamthungo yesikwere imibhobho yentsimbi enoxande kunye nezinye iimveliso zemibhobho yesikwere.
I-Q345B ityhubhu yesikwere iveliswa ngokwemigangatho yesizwe ye-GBT 6728-2002 epholileyo epholileyo yecandelo lentsimbi yobukhulu, imilo, ubunzima kunye nokuphambuka okuvumelekileyo kwesakhiwo.Yenziwe ngentsimbi ye-Q345B yentsimbi emva kokulungiswa kunye nokuqengqeleka.I-tube ye-square ye-Q345B yenziwe ngezinto ze-Q345B (i-alloy ephantsi), ehluke kakhulu kwi-tube yesikwere eqhelekileyo kwizinto ezibonakalayo (Q195, Q215, Q235).Ngokuqhelekileyo, i-Q345B strip steel (i-alloy ephantsi) ayipakishwanga., I-Flattened, i-crimped, i-welded ukwenza i-tube ejikelezayo, kwaye emva koko igqitywe kwi-tube yesikwere ukusuka kumbhobho ojikelezayo kwaye inqunyulwe ubude obufunekayo.Ubude obuqhelekileyo buziimitha ezi-6, kwaye inani elikhulu leemitha ezili-12 linokucutshungulwa ngokweemfuno zabathengi.Ngokubanzi, ubungakanani obuncinci bungamaqhekeza angama-50 kwipakethi nganye, kwaye ubungakanani obukhulu bungamaqhekeza ama-4 kwaye ubunzima bulawulwa malunga neetoni ezi-3.Iityhubhu ze-Q345B ubukhulu becala ziyi-80MM * 80MM-500MM * 500MM kwiinkcukacha ezinkulu kwisitokhwe, kwaye ubukhulu yi-3MM-16MM.
Q345B ityhubhu yesikwere ingenamthungo kwaye idityanisiwe
Q345B ityhubhu yesikwere engenamthungo yenziwa ngokukhupha i-Q345B ityhubhu engqukuva engenamthungo.
Q345B square tube iplastiki
I-Plastiki ibhekisela kwikhono lezinto zetsimbi ukuvelisa i-deformation yeplastiki (i-deformation esisigxina) ngaphandle kokulimala phantsi komthwalo.
Q345B ubulukhuni ityhubhu yesikwere
Ukuqina ngumlinganiselo wobunzima bezinto zetsimbi.Eyona ndlela isetyenziswa ngokuqhelekileyo yokulinganisa ubulukhuni kwimveliso yindlela yobulukhuni yokungena, esebenzisa i-indenter yesimo esithile sejometri ukucinezela kumphezulu wezinto zetsimbi eziza kuvavanywa phantsi komthwalo othile, kwaye ixabiso lobulukhuni limiselwa ngokutsho iqondo lokujongwa.
Iindlela ezisetyenziswa ngokuqhelekileyo ziquka ukuqina kweBrinell (HB), ukuqina kweRockwell (HRA, HRB, HRC) kunye nokuqina kweVickers (HV).
I-Q345B ityhubhu yesikwere yityhubhu yentsimbi ebhityileyo, ekwabizwa ngokuba yintsimbi egoba efrijini.Liyintsimbi yecandelo elinesikwele secandelo lomnqamlezo kunye nobukhulu benziwe nge-Q345B eshushu-eshushu okanye i-coil-rolled strip okanye i-coil njengento esisiseko, eyenziwa ngokugoba okubandayo kwaye emva koko idityaniswe yi-welding high-frequency welding.Ukongeza ukutyeba eludongeni eshushu-iqengqeleke extra-thick eludongeni ityhubhu square, ubungakanani ikona kunye emphethweni flatness baye bafikelela okanye bade bagqithe kwinqanaba lokumelana welded abandayo-enziwe square tube.
Q345B ukusetyenziswa ityhubhu square
Imibhobho yesikwere ye-Q345B isetyenziswa ngokubanzi kulwakhiwo, ukuveliswa koomatshini, iiprojekthi zolwakhiwo lwentsimbi, ukwakhiwa kweenqanawa, inkxaso yamandla elanga, ubunjineli besakhiwo sentsimbi, ubunjineli bamandla, izityalo zamandla, oomatshini bezolimo kunye neekhemikhali, iindonga zamakhethini eglasi, i-chassis yemoto, izikhululo zeenqwelo moya, njl.
Q345B isikwere umbhobho wesebe ukubala ifomula: 4 macala wongezwa * ubukhulu * 0.00785 * ubude
Q345B umbhobho woxande inkxaso ifomula yokubala: (ubude becala + ubude becala) * 2 * 0.00785 * ubukhulu bodonga * ubude
