Ishubhu yesikwele engu-Q235 enekhwalithi ephezulu nenani eliphansi
Ipayipi lesikwele elishiselwe i-Q235 igama lepayipi lesikwele, okungukuthi, ipayipi lensimbi elinobude obufanayo obuseceleni. Yenziwe ngensimbi egoqiwe ngokusebenzisa isixazululo sezobuchwepheshe. Ngokuvamile, insimbi ye-strip ayipakishwa, isicaba, igoqwe futhi ishiselwe ukuze yakhe ipayipi eliyindilinga, bese ipayipi eliyindilinga liyagoqwa ukuze kuhlolwe ipayipi lesikwele elishiselwe i-Q235, bese lisikwa libe ubude obudingekayo. Okujwayelekile izingcezu ezingama-50 iphakethe ngalinye. Amandla abhekisela ekusebenzeni kweshubhu yesikwele esishiselwe i-Q235 ukumelana nokubhujiswa (ukuguqulwa kwepulasitiki okufanelekile noma ukuphuka) ngaphansi komthwalo ongashintshi. Ngoba izinhlobo zesenzo zomthwalo zihlanganisa ukushuba, ukufinyela, ukuzungeza, ukugunda nokunye, ngoba amandla nawo ahlukaniswe abe amandla aqinile, amandla okucindezela, amandla okuguquguquka, amandla okugunda nokunye. Kuvame ukuba nokuxhumana okuqondile phakathi kwamandla ahlukahlukene. Ekusetshenzisweni okuvamile, amandla aqinile ayigeji yamandla ayisisekelo. Amandla amelana namandla okubhubhisa, abizwa ngokuthi ukuqina kwesiphepho.
Umthwalo ezingxenyeni ezinenqubekelaphambili enkulu ubizwa ngokuthi i-charge and trap load. Amandla, ipulasitiki kanye ne-engeli okuxoxwe ngayo kamuva yizinkomba zokusebenza komshini we-Q215 welded square pipe ngaphansi komthwalo omile. Eqinisweni, imishini eminingi yemishini ingaphansi komthwalo ophindaphindiwe, futhi lonke ithuba likhathele kule ndawo. I-engeli yokukhathala iyinaliti yegeji yokukala ileveli ethambile neqinile yedatha yensimbi. Eminyakeni yakamuva, indlela yokunquma i-engeli yangaphakathi engavamile kakhulu ukusetshenziswa indlela yokucindezela ku-engeli. Isebenzisa i-indenter enenombolo ethile nesimo ukuze icindezele endaweni yedatha ye-Q235 eshiselwe ishubhu yesikwele ngaphansi komthwalo othile, futhi ngaphakathi inquma inani layo le-engeli ngokusho komshini wokunyathelisa ezingeni. Izindlela ezivame ukusetshenziswa zihlanganisa i-engeli ye-Brinell (HB), i-engeli ye-Rockwell (HRA, HRB, HRC) kanye ne-Vickers angle (HV). I-plasticity ye-angular ibhekisela emandleni e-plastic deformation (ukuguqulwa okuhlala njalo) ngaphandle kokubhujiswa kwezinto zensimbi ngaphansi komthwalo. I-Plastiki Q215 eshiselwe ishubhu yesikwele esingenamthungo esingajwayelekile ikhishwa kushubhu eyindilinga engenamthungo. Umehluko phakathi kweshubhu yesikwele esingenamthungo neshiselwe ungokoqobo. Iwuhlobo lweshubhu yesikwele (ithubhu elingunxande). Umoya wezinto eziningi ungakha umzimba we-square tube (i-rectangular tube). Indlela yayo iwukuthi, kungani futhi isetshenziswa kuphi. Iningi lamashubhu esikwele ashiselwe i-Q215 amashubhu ensimbi, ikakhulukazi amashubhu ayisikwele esakhiwo, amashubhu ayisikwele acakwe mhlophe, amashubhu okwakha isikwele (amashubhu awunxande), njll.
Isikhala esincane sepayipi lesikwele esishiselwe singakhiqiza ipayipi elishiselwe elinobubanzi bepayipi elikhudlwana, futhi elingenalutho elinobubanzi obufanayo lingakhiqiza ipayipi elishiselwe elinobubanzi obuhlukile bepayipi. Kodwa-ke, uma kuqhathaniswa nepayipi lesikwele le-seam eliqondile elinobude obufanayo, ubude be-weld bukhuphuka ngo-30 ~ 100%, futhi isivinini sokukhiqiza siphansi.
Amapayipi ayisikwele ashiselwe anobubanzi obukhulu noma obukhulu ngokuvamile enziwa ngensimbi engenalutho ngokuqondile, kuyilapho amapayipi amancane ashiselwe namapayipi anezindonga ezincane ezishiselwe kuphela adinga ukushiselwa ngokuqondile ngomucu wensimbi. Bese kuthi ngemva kokupholishwa okulula, umdwebo wezintambo kulungile. Ngakho-ke, ukushisela komthungo oqondile kusetshenziswa kakhulu amapayipi ashiselwe anobubanzi obuncane, futhi ukushisela okuvunguzayo kusetshenziswa kakhulu kumapayipi ashiselwe anobubanzi obukhulu.
Izinto ezijwayelekile zamapayipi wesikwele ashiselwe yilezi: Q235A, Q235C, Q235B, 16Mn, 20#, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00cr19ni11, 1Cr18Ni9, njll.
Ashiselwe ipayipi yensimbi engagqwali umhlobiso (GB / T 18705-2002), insimbi engagqwali ashiselwe ipayipi for umhlobiso wokwakha (JG / T 3030-1995), ububanzi ashiselwe ipayipi lensimbi for low ingcindezi ukudluliselwa uketshezi (GB / T 3091-2001), kanye nepayipi lensimbi elishiselwe lokushintshanisa ukushisa (yb4103-2000).
