I-Q345B isiqinisekiso sekhwalithi yepayipi lesikwele esiwugqinsi
Ipayipi eliyisikwele elinezindonga eliwugqinsi oluwugqinsi oluwugqinsi olukhanyayo elinengxenye yesikwele engenalutho, eyaziwa nangokuthi iphrofayili yensimbi eyakhiwe ngokubanda. Kuyinsimbi yesigaba enomumo nosayizi wesigaba sesikwele, esenziwe ngomugqa ogoqekayo we-Q235 ogoqekayo noma ogoqelwe ngokubanda noma ikhoyili njengesisekelo, ukugoba okubandayo kanye ne-high-frequency welding.
Ngokwenqubo yokukhiqiza, ipayipi eliyisikwele eliwugqinsi elinobubanzi obukhulu lihlukaniswe ipayipi eliyisikwele elishisayo eligoqiwe, elidonswa ngamakhaza aminyene ipayipi lesikwele, ipayipi eliyisikwele elikhishwe ngodonga kanye nepayipi eliyisikwele elishisiwe.
(a) Ngokwenqubo - i-arc welding square tube, ukumelana nokushisela ishubhu yesikwele (imvamisa ephezulu kanye nemvamisa ephansi), i-gas welding square tube kanye nesithando somlilo welding square tube
(b) Ihlukaniswe nge-weld - ipayipi eliyisikwele elishiselwe ngokuqondile kanye nepayipi eliyisikwele elishiselwe elisontekile
Ipayipi eliyisikwele elikhulu eliwugqinsi elibanzi lihlukaniswe laba ipayipi elivamile le-carbon steel square kanye nepayipi eliyisikwele le-alloy eliphansi ngokusho kwezinto. Okuvamile carbon steel ihlukaniswe: Q195, Q215, Q235, SS400, 20 # steel, 45 # steel, njll; Izinsimbi eziphansi ze-alloy zihlukaniswe nge-Q345, 16Mn, Q390, St52-3, njll.
Ipayipi lensimbi yesikwele, ipayipi lensimbi eliwugqinsi, ipayipi elikhulu lensimbi eliyisikwele, ipayipi lensimbi elingenamthungo, ipayipi lensimbi eliyisikwele eliphansi, 135 * 135 * 10 ipayipi lensimbi yesikwele, ipayipi lensimbi yesikwele lombhoshongo we-crane, i-Q345B ipayipi lensimbi ephansi ye-alloy square, 20# ipayipi lensimbi engenamthungo
Ishubhu yesikwele, njengoba negama liphakamisa, iwuhlobo lweshubhu yesikwele. Izinto eziningi zingakha ishubhu yesikwele. Isetshenziselwa, yini okufanele yenziwe futhi isetshenziswe kuphi. Amashubhu amaningi ayizikwele amashubhu ensimbi, ikakhulukazi amashubhu ayisikwele esakhiwo, amashubhu ayisikwele okuhlobisa, amashubhu okwakha isikwele, njll.
Ipayipi lesikwele yigama lepayipi eliyisikwele, okungukuthi, ipayipi lensimbi elinobude obulinganayo obuhlangothini. Yenziwe ngensimbi egoqiwe ngemuva kokwelashwa kwenqubo. Ngokuvamile, insimbi ye-strip iyakhishwa, ilinganiswe, igwetshwe futhi ishiselwe ukuze yakhe ipayipi eliyindilinga, bese igoqwa ibe yipayipi eliyisikwele, bese isikwa ubude obudingekayo. Ngokuvamile izingcezu ezingu-50 iphakethe ngalinye.
Amashubhu ayisikwele angahlukaniswa abe angenamthungo futhi ashiselwe. Amashubhu ayisikwele angenamthungo akhishwa kumashubhu ayindilinga angenamthungo. Ipayipi lensimbi yesikwele, ipayipi lensimbi eliwugqinsi, ipayipi elikhulu lensimbi eliyisikwele, ipayipi lensimbi elingenamthungo, ipayipi lensimbi eliyisikwele eliphansi, 135 * 135 * 10 ipayipi lensimbi yesikwele, ipayipi lensimbi yesikwele lombhoshongo we-crane, i-Q345B ipayipi lensimbi ephansi ye-alloy square, 20# ipayipi lensimbi engenamthungo
1. Ukuhlaziywa kwenkomba yokusebenza kwe-square tube - plasticity
I-Plasticity ibhekisela ekhonweni lezinto zensimbi ukukhiqiza ukuguqulwa kwepulasitiki (ukuguqulwa okuhlala njalo) ngaphandle kokulimala ngaphansi komthwalo.
2. Ukuhlaziywa kwenkomba yokusebenza kweshubhu yesikwele - ubulukhuni
Ukuqina buyisikhombi sokulinganisa ubulukhuni nokuthambile kwezinto zensimbi. Njengamanje, indlela evame ukusetshenziswa kakhulu yokukala ubulukhuni ekukhiqizeni indlela yobulukhuni bokuhlehlisa. Isebenzisa i-indenter enejiyomethri ethile ukuze icindezele ebusweni bensimbi ehloliwe ngaphansi komthwalo othile, futhi inquma ubulukhuni bayo ngokwezinga lokuhlehlisa.
Izindlela ezivame ukusetshenziswa zihlanganisa ukuqina kwe-Brinell (HB), ukuqina kwe-Rockwell (HRA, HRB, HRC) kanye nokuqina kwe-Vickers (HV).
3. Ukuhlaziywa kwenkomba yokusebenza kwe-square tube - ukukhathala
Amandla, ipulasitiki nobulukhuni okuxoxwe ngakho ngenhla zonke ziyizinkomba zezakhiwo zemishini yensimbi ngaphansi komthwalo omile. Eqinisweni, izingxenye eziningi zomshini zisebenza ngaphansi komthwalo we-cyclic, lapho ukukhathala kuzokwenzeka khona.
4. Ukuhlaziywa kwenkomba yokusebenza kweshubhu yesikwele - ukuqina komthelela
Umthwalo osebenza engxenyeni ngesivinini esikhulu ubizwa ngokuthi i- impact load, futhi ikhono lensimbi lokumelana nokwehluleka ngaphansi komthwalo womthelela kubizwa ngokuthi ukuqina komthelela.
5. Ukuhlaziywa kwenkomba yokusebenza kwepayipi lesikwele - ipayipi lensimbi yesikwele yamandla, ipayipi lensimbi eliyisikwele eliwugqinsi, ipayipi elikhulu lensimbi eliyisikwele, ipayipi lensimbi elingenamthungo, ipayipi lensimbi eliphansi le-alloy, 135 * 135 * 10 ipayipi lensimbi yesikwele, ipayipi lensimbi yesikwele yombhoshongo we-crane. , Q345B low ingxubevange isikwele ipayipi yensimbi, 20# nekhono isikwele ipayipi insimbi
Amandla asho ukumelana kwezinto zensimbi ekuhlulekeni (ukuguqulwa kwepulasitiki ngokweqile noma ukuphuka) ngaphansi komthwalo omile. Njengoba izindlela zesenzo zomthwalo zifaka ukungezwani, ukucindezelwa, ukugoba nokugunda, amandla nawo ahlukaniswe abe amandla aqinile, amandla okucindezela, amandla okuguquguquka namandla okugunda. Kuvame ukuba nokuxhumana okuthile phakathi kwamandla ahlukahlukene. Ngokuvamile, amandla okuqina asetshenziswa njengesikhombi samandla esiyisisekelo.
