Q345B eludongeni olungqingqwa lombhobho wesiqinisekiso somgangatho
Umbhobho otyebileyo otyebileyo osisikwere luhlobo lombhobho wentsimbi ongqindilili ongqindilili kunye necandelo lesikwere elinomgongxo, okwaziwa ngokuba yiprofayili yentsimbi ebandayo. Yintsimbi yecandelo elinobume becandelo lesikwere kunye nobukhulu, olwenziwa nge-Q235 eshushu-eshushu okanye i-coil-rolled strip okanye i-coil njengento esisiseko, ukugoba okubandayo kunye ne-high-frequency welding.
Ngokwenkqubo yemveliso, umbhobho oshinyeneyo wodonga olungqingqwa wahlulwe waba ngumbhobho oshinyeneyo wodonga lwesikwere, umbhobho otyhidiweyo wodonga lwesikwere, umbhobho otyhidiweyo wesikwere kunye nombhobho odityanisiweyo wesikwere.
(a) Ngokwenkqubo - i-arc welding square tube, ukumelana ne-welding square tube (i-frequency ephezulu kunye ne-frequency ephantsi), i-gas welding square tube kunye ne-furnace welding square tube.
(b) Ukwahlulwe nge weld - umbhobho odityanisiweyo othe tye kunye nombhobho osisikwere odityanisiweyo
Umbhobho omkhulu otyebileyo wodonga lwesikwere wahlulwe kumbhobho osisikwere wekhabhoni oqhelekileyo kunye nombhobho osezantsi wealloyi yesikwere ngokwezinto eziphathekayo. Intsimbi yekhabhoni eqhelekileyo yahlulwe yaba: Q195, Q215, Q235, SS400, 20 # intsimbi, 45 # intsimbi, njl; Iintsimbi ze-alloy eziphantsi zihlulwe zibe yi-Q345, 16Mn, Q390, St52-3, njl.
Umbhobho wentsimbi yesikwere, udonga olungqingqwa lombhobho wentsimbi, umbhobho omkhulu wentsimbi, umbhobho wentsimbi ongenamthungo, umbhobho wentsimbi ophantsi ophantsi, 135 * 135 * 10 umbhobho wentsimbi yesikwere, umbhobho wentsimbi yesikwere, umbhobho wentsimbi osezantsi, Q345B 20 # ingenamthungo umbhobho yentsimbi yesikwere
Ityhubhu yesikwere, njengoko igama libonisa, luhlobo lwetyhubhu yesikwere. Izinto ezininzi zinokwenza ityhubhu yesikwere. Isetyenziselwa ukwenza ntoni, kwaye isetyenziselwa phi. Uninzi lweetyhubhu zesikwere ziityhubhu zentsimbi, uninzi lweetyhubhu zesikwere, iityhubhu zokuhombisa, iityhubhu zesikwere, njl.
Umbhobho wesikwere ligama lombhobho wesikwere, oko kukuthi, umbhobho wentsimbi onobude obulinganayo becala. Yenziwe ngentsimbi yentsimbi eqengqelekayo emva konyango lwenkqubo. Ngokuqhelekileyo, intsimbi ye-strip ikhutshwe, ihlanjululwe, igxininiswe kwaye ifakwe kwi-welded ukuze yenze umbhobho ojikelezayo, emva koko ifakwe kumbhobho wesikwere, kwaye inqunyulwe ubude obufunekayo. Ngokubanzi amaqhekeza angama-50 ngepakethe nganye.
Iityhubhu zesikwere zinokwahlulwa zibe zingenamthungo kunye ne-welded. Iityhubhu zesikwere ezingenamthungo zikhutshelwa kwiityhubhu ezijikelezayo ezingenamthungo. Umbhobho wentsimbi yesikwere, udonga olungqingqwa lombhobho wentsimbi, umbhobho omkhulu wentsimbi, umbhobho wentsimbi ongenamthungo, umbhobho wentsimbi ophantsi ophantsi, 135 * 135 * 10 umbhobho wentsimbi yesikwere, umbhobho wentsimbi yesikwere, umbhobho wentsimbi osezantsi, Q345B 20 # ingenamthungo umbhobho yentsimbi yesikwere
1. Uhlalutyo lwesalathisi sokusebenza setyhubhu yesikwere - iplastiki
I-Plastiki ibhekisela kwikhono lezinto zetsimbi ukuvelisa i-deformation yeplastiki (i-deformation esisigxina) ngaphandle komonakalo phantsi komthwalo.
2. Uhlalutyo lwesalathisi sokusebenza setyhubhu yesikwere - ukuqina
Ubunzima buyisalathisi sokulinganisa ubunzima kunye nokuthamba kwezinto zetsimbi. Okwangoku, eyona ndlela ixhaphakileyo yokulinganisa ubulukhuni kwimveliso yindlela yokuqina kwe-indentation. Isebenzisa i-indenter ngejometri ethile ukucinezela kumphezulu wezinto zetsimbi ezivavanyiweyo phantsi komthwalo othile, kwaye imisela ixabiso lobunzima bayo ngokweqondo lokungena.
Iindlela ezisetyenziswa ngokuqhelekileyo ziquka ukuqina kweBrinell (HB), ukuqina kweRockwell (HRA, HRB, HRC) kunye nokuqina kweVickers (HV).
3. Uhlalutyo lwesalathisi sokusebenza setyhubhu yesikwere - ukukhathala
Amandla, iplastiki kunye nokuqina okuxoxwe ngasentla kuzo zonke izibonakaliso zeempawu zomatshini wesinyithi phantsi komthwalo omileyo. Ngapha koko, uninzi lwamalungu omatshini asebenza phantsi komthwalo we-cyclic, apho kuya kwenzeka ukukhathala.
4. Uhlalutyo lwesalathisi sokusebenza setyhubhu yesikwere - ukuqina kwempembelelo
Umthwalo osebenza kwicandelo ngesantya esikhulu ubizwa ngokuba ngumthwalo wempembelelo, kwaye ukukwazi kwesinyithi ukuxhathisa ukusilela phantsi komthwalo wempembelelo kubizwa ngokuba bukuqina kwempembelelo.
5. Uhlalutyo lwesalathiso sokusebenza kombhobho osisikwere - umbhobho wentsimbi yesikwere, udonga olungqingqwa lombhobho wentsimbi, umbhobho wentsimbi, umbhobho wentsimbi ongenamthungo. , Q345B ephantsi ingxubevange isikwere umbhobho yentsimbi, 20# ingenamthungo umbhobho yentsimbi square
Amandla abhekisela ekuchaseni izinto zetsimbi ukungaphumeleli (i-deformation yeplastiki egqithisileyo okanye i-fracture) phantsi komthwalo we-static. Kuba iimowudi zentshukumo zomthwalo zibandakanya ukuxinana, ukucinezelwa, ukugoba kunye nokucheba, amandla aphinde ahlulwe abe ngamandla okuqina, amandla oxinzelelo, amandla okugoba kunye namandla okucheba. Kudla ngokubakho unxibelelwano oluthile phakathi kwamandla ahlukeneyo. Ngokubanzi, amandla okuqina asetyenziswa njengesona salathisi samandla asisiseko.
