Q235 ityhubhu yesikwere enomgangatho ophezulu kunye nexabiso eliphantsi
I-Q235 i-welded square pipe yi-appellation ye-square pipe, oko kukuthi, umbhobho wentsimbi kunye nobude becala elifanayo. Yenziwe ngentsimbi yentsimbi eqengqelekayo ngesisombululo setekhnoloji. Ngokuqhelekileyo, intsimbi ye-strip ayipakishwanga, icwecwe, igobile kwaye idityaniswe ukuze yenze umbhobho ojikelezayo, kwaye ke umbhobho ojikelezayo ujikelezwe ukujonga umbhobho we-square we-Q235 odityanisiweyo, kwaye emva koko unqunywe ubude obufunekayo. Okuqhelekileyo ngamaqhekeza angama-50 ngephakheji. Amandla abhekisela kumsebenzi we-Q235 welded square tube ukumelana nokutshatyalaliswa (i-plastic deformation efanelekileyo okanye i-fracture) phantsi komthwalo we-static. Ngenxa yokuba iifom zentshukumo zomthwalo zibandakanya ukuqina, ukufinyela, ukugoba, ukucheba njalo njalo, kuba amandla ahlulahlulwe ngokwamandla okuxinana, amandla oxinzelelo, amandla okuguquguquka, amandla okucheba njalo njalo. Kudla ngokubakho unxibelelwano oluqinisekileyo phakathi kwamandla ahlukeneyo. Ekusetyenzisweni okuqhelekileyo, amandla okuqina yeyona nto isisiseko sokulinganisa amandla. Amandla axhathisa amandla entshabalalo, abizwa ngokuba bubulukhuni besaqhwithi.
Umthwalo kwiindawo ezinenkqubela phambili enkulu kuthiwa yintlawulo kunye nomthwalo womgibe. Amandla, iplastiki kunye ne-angle exoxwe ngayo kamva zizibonakaliso zokusebenza komatshini we-Q215 welded square pipe phantsi komthwalo omileyo. Ngokwenza, oomatshini abaninzi bemishini baphantsi komthwalo ophindaphindiweyo, kwaye lonke ithuba lidiniwe kule ndawo. I-engile yokudinwa yinaliti yokulinganisa ukulinganisa inqanaba elithambileyo nelilukhuni ledatha yesinyithi. Kwiminyaka yakutshanje, eyona ndlela inqabileyo yokumisela i-engile yangaphakathi kukucinezela kwindlela ye-engile. Isebenzisa i-indenter kunye nenani elithile kunye nokuma ukucinezela kwi-data surface ye-Q235 i-welded square tube phantsi komthwalo othile, kwaye ngaphakathi inquma ixabiso layo le-angle ngokwe-press in level. Iindlela ezisetyenziswa ngokuqhelekileyo ziquka i-Brinell angle (HB), i-Rockwell angle (HRA, HRB, HRC) kunye ne-Vickers angle (HV). Iplastiki ye-angular ibhekisela kumandla okuguqulwa kweplastiki (i-deformation esisigxina) ngaphandle kokutshatyalaliswa kwezinto zetsimbi phantsi komthwalo. Iplastiki ye-Q215 edityanisiweyo ityhubhu yesikwere engasiyo i-standard engenamthungo yesikwere ikhutshiwe kwityhubhu ejikelezayo engenamthungo. Umahluko phakathi kwetyhubhu yesikwere engenamthungo kunye ne-welded yeyoqobo. Luhlobo lwetyhubhu yesikwere (ityhubhu yoxande). Umoya wezinto ezininzi unokwenza umzimba we-square tube (ityhubhu ye-rectangular). Indawo yayo kukuba, kutheni kwaye isetyenziswa phi. Uninzi lweetyhubhu zesikwere ze-Q215 zityhubhu zentsimbi, ubukhulu becala iityhubhu zesikwere, iityhubhu ezicakwe mhlophe, ukwakha iityhubhu zesikwere (iityhubhu ezixande), njl.
Indawo engenanto emxinwa yombhobho odityanisiweyo odityanisiweyo unokuvelisa umbhobho odityanisiweyo kunye nobubanzi bombhobho omkhulu, kwaye indawo engenanto enobubanzi obufanayo inokuvelisa umbhobho odityanisiweyo kunye nobubanzi bombhobho ohlukeneyo. Nangona kunjalo, xa kuthelekiswa nombhobho othe tye we-square we-square kunye nobude obufanayo, ubude be-weld bunyuka nge-30 ~ 100%, kwaye isantya semveliso siphantsi.
Imibhobho edityanisiweyo yesikwere enedayamitha enkulu okanye engqindilili ngokubanzi yenziwe ngentsimbi engenanto ngokuthe ngqo, ngelixa imibhobho edityanisiweyo emincinci kunye nemibhobho edityanisiweyo edityanisiweyo kufuneka idityaniswe ngokuthe ngqo ngomcu wentsimbi. Emva kokupholisha okulula, umzobo wocingo ulungile. Ke ngoko, ukuwelda komthungo othe tye kusetyenziswa kakhulu kwimibhobho edityanisiweyo enobubanzi obuncinci, kwaye i-spiral welding isetyenziswa kakhulu kwimibhobho edityanisiweyo enobubanzi obukhulu.
Izinto eziqhelekileyo zemibhobho edityanisiweyo yesikwere zezi: Q235A, Q235C, Q235B, 16Mn, 20#, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00cr19ni11, 1Cr18Ni9, njl.
Welded steel stainless umbhobho yokuhombisa (GB / T 18705-2002), intsimbi edityanisiweyo umbhobho ukuhombisa isakhiwo (JG / T 3030-1995), ubukhulu obukhulu welded umbhobho yentsimbi ukudluliselwa ulwelo uxinzelelo oluphantsi (GB / T 3091-2001), kunye nombhobho wentsimbi odityanisiweyo wokutshintsha ubushushu (yb4103-2000).
