I-Rebar igama elijwayelekile lamabha ensimbi aginqike ngezimbambo ezishisayo.Ibanga lensimbi evamile egoqelwe ngokushisayo liqukethe i-HRB kanye nephuzu elincane lokuvunwa lebanga.H, R, kanye no-B yizinhlamvu zokuqala zesiNgisi zamagama amathathu, i-Hotrolled, Ribbed, ne-Bars, ngokulandelana.Imigoqo yensimbi enezimbambo ezishisayo ihlukaniswe ngamabanga amathathu: i-HRB335 (ibanga elidala lingu-20MnS), i-HRB400 (ibanga elidala ngu-20MnSiV, 20MnSiNb, 20Mnti) kanye ne-HRB500.
Uhlolojikelele
Ibha yensimbi egoqwe kahle enezinhlamvu ezishisayo Uhlamvu lokuqala lwesiNgisi (Fine) elithi "fine" lwengezwe kugama lomkhiqizo webha yensimbi enezimbambo ezishisayo.njengokuthi:
I-HRBF335HRBF400, HRBF500.Amabanga asebenzayo ezakhiwo zokuzamazama komhlaba ezinezidingo eziphezulu yilawa: engeza u-E ngemva kwamabanga akhona (isibonelo: HRB400E
I-HRBF400E)
Ukusetshenziswa okuyinhloko: esetshenziswa kabanzi ekwakhiweni kobunjiniyela bomphakathi njengezindlu, amabhuloho, imigwaqo, njll.
Umehluko phakathi kwe-rebar nebha eyindilinga: Umehluko phakathi kwe-rebar kanye nebha eyindilinga ukuthi kukhona izimbambo ezinde nezimbambo ezivundlile ngaphezulu, ngokuvamile ezinezimbambo ezimbili ezinde nezimbambo eziphambene ezisatshalaliswe ngokulinganayo ohlangothini lobude.I-Rebar iyinsimbi yengxenye encane, esetshenziselwa ikakhulukazi uhlaka lwamathambo ezingxenye zokwakha zikakhonkolo eziqinisiwe.Ekusetshenzisweni, amandla athile emishini, ukusebenza kwe-deformation yokugoba nokusebenza kwenqubo yokushisela kuyadingeka.Amabhilidi wezinto ezingavuthiwe zokukhiqizwa kwama-reba yinsimbi yesakhiwo sekhabhoni noma insimbi yesakhiwo enengxubevange ephansi ephathwa ngokuthulisa.
Insimbi yesakhiwo, imigoqo yensimbi eqediwe ilethwa esimweni esishisayo, esijwayelekile noma esishisayo.
uhlobo
Kunezindlela ezimbili ezivame ukusetshenziswa zokuhlukanisa ze-rebar;eyodwa ihlukaniswa ngokuma kwejiyomethri, futhi ihlukaniswa noma ihlukaniswe ngokuvumelana nokuma kwesigaba esiphambanayo sombambo ovundlile kanye nokuhlukana kwezimbambo.
Uhlobo, njenge-British Standard (BS4449), ibha kabusha ihlukaniswe ngokuthi |thayipha, ngiyathayipha.Lokhu kuhlukaniswa kukhombisa ngokuyinhloko ukusebenza okubambekayo kwe-rebar.Okubili kunjalo
Ukuhlelwa kokusebenza (ibanga), njengezinga lezwe lami lokusebenza lamanje, i-rebar ithi (GB1499.2-2007) induku yocingo ithi 1499.1-2008), ngokuya ngebanga lamandla
Okuhlukile (iphuzu lokuvunwa/amandla okubamba), i-rebar ihlukaniswe ngamamaki ama-3;ku-Japanese Industrial Standard (JISG3112), i-rebar ihlukaniswe yaba izinhlobo ezi-5 ngokuya ngokusebenza okuphelele;ku-British Standard (BS4461), ibha kabusha iphinde icaciswe Amazinga amaningana okuhlolwa kokusebenza.Ngaphezu kwalokho, i-rebar nayo ingacutshungulwa ngokuya ngesicelo.
Ukuhlelwa, okufana nezinsimbi ezijwayelekile zokhonkolo oqinisiwe nezinsimbi ezifakwe ukushisa zokhonkolo oqiniswe ngokucindezelwe.
