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 zamagama amathathu, i-Hotrolled, Ribbed, kanye ne-Bars, ngokulandelana.
Ibha yensimbi enezimbambo ezishisayo ihlukaniswe ngamabanga amathathu: i-HRB335 (ibanga elidala ngu-20MnSi), ibanga lesithathu i-HRB400 (ibanga elidala lingu-20MnSiV, 20MnSiNb, 20Mnti), kanye nebanga lesine i-HRB500.
Kunezindlela ezimbili ezivame ukusetshenziswa zokuhlukanisa ze-rebar: eyodwa iwukuhlukanisa ngokuma kwejiyomethri, nokuhlukanisa noma ukuhlukanisa ngokusho komumo onqamulayo wombambo ovundlile kanye nokuhlukana kwezimbambo.Uhlobo II.Lokhu kuhlukaniswa kukhombisa ngokuyinhloko ukusebenza okubambekayo kwe-rebar.Okwesibili kusekelwe ekuhlukaniseni ukusebenza (ibanga), njengezinga lokusetshenziswa lamanje lezwe lami, i-rebar ithi (GB1499.2-2007) induku yocingo ingu-1499.1-2008), ngokuya ngeleveli yamandla (iphuzu lokukhipha/amandla okubamba) I-rebar ihlukaniswe ngamabanga ama-3;ku-Japanese Industrial Standard (JI SG3112), i-rebar ihlukaniswe yaba izinhlobo ezi-5 ngokuya ngokusebenza okuphelele;ku-British Standard (BS4461), amamaki ambalwa okuhlolwa kokusebenza kwe-rebar nawo acacisiwe.Ngaphezu kwalokho, ama-rebar angabuye ahlukaniswe ngokuya ngokusetshenziswa kwawo, njengezinsimbi zensimbi ezijwayelekile zokhonkolo oqinisiwe kanye nezinsimbi zensimbi eziphathwa ngokushisa zokhonkolo oqinisiwe oqinisiwe.
I-Rebar iyibha yensimbi enezimbambo ngaphezulu, eyaziwa nangokuthi ibha yensimbi eyi-ribbed, ngokuvamile enezimbambo ezi-2 longitudinal nezimbambo eziphambanayo ezisatshalaliswe ngokulinganayo ohlangothini lobude.Ukuma kobambo oluphambanayo ku-spiral, herringbone kanye ne-crescent shape.Kuvezwe ngamamilimitha obubanzi obujwayelekile.Ububanzi obuncane bebha elinezimbambo buhambisana nobubanzi obungajwayelekile bebha eyindilinga yesigaba esiphambene esilinganayo.Ububanzi obujwayelekile be-rebar bungu-8-50 mm, futhi ububanzi obunconywayo bungu-8, 12, 16, 20, 25, 32, kanye no-40 mm.Imigoqo yensimbi enezimbambo ikakhulukazi ingaphansi kwengcindezi eqinile kukhonkolo.Ngenxa yesenzo sezimbambo, imigoqo yensimbi enezimbambo inekhono elikhulu lokubopha ngokhonkolo, ukuze ikwazi ukumelana kangcono nesenzo samandla angaphandle.Imigoqo yensimbi enezimbambo isetshenziswa kabanzi ezakhiweni ezihlukahlukene zokwakha, ikakhulukazi ezinkulu, ezisindayo, ezilula ezinodonga oluncane oluncane kanye nezakhiwo zokwakha eziphakeme.
I-Rebar ikhiqizwa izigayo ezincane ezigoqayo.Izinhlobo eziyinhloko zezigayo ezincane ezigoqayo yilezi: eziqhubekayo, eziqhubekayo kanye nomugqa.Iningi lezigayo ezintsha nezisetshenziswayo ezincane eziginqikayo emhlabeni ziyaqhubeka ngokugcwele.Izigayo ze-rebar ezidumile ziyizigayo ze-rebar zenhloso ezijwayelekile ezinesivinini esiphezulu kanye nezigayo ze-rebar ezikhiqiza kakhulu eziyisi-4.
I-billet esetshenziswa kumshini wokugaya omncane oqhubekayo ngokuvamile i-billet yokuphonsa eqhubekayo, ubude obuhlangothini ngokuvamile buba ngu-130 ~ 160mm, ubude ngokuvamile buba ngamamitha angu-6~12, kanti isisindo se-billet esisodwa singamathani angu-1.5~3.Iningi lemigqa egoqayo ihlelwa ngokushintshana ngokuvundlile nangokuqondile, ukuze kuzuzwe ukugoqeka okungagungxuki emugqeni.Ngokwezigayo ezihlukene ze-billet kanye nosayizi bomkhiqizo oqediwe, kukhona izigayo ezincane eziyi-18, 20, 22, nezingu-24, kanti eziyi-18 ziyi-mainstream.Ukuginqika kwebha ngokuvamile kusebenzisa izinqubo ezintsha ezifana nezitebhisi zokushisa, ukwehla kwamanzi anomfutho ophezulu, ukuginqika okunokushisa okuphansi, nokugingqika okungapheli.Ukugingqika okungalungile kanye nokuginqika okuphakathi kuyathuthukiswa ukuze kuhambisane namabhilidi amakhulu futhi kuthuthukiswe ukunemba kokugoqa.Izigayo zokuphothula ikakhulukazi Ukunemba Okuthuthukisiwe kanye nesivinini (kufika ku-18m/s).Imininingwane yomkhiqizo imvamisa ingu-ф10-40mm, futhi kukhona no-ф6-32mm noma ф12-50mm.Amamaki ensimbi akhiqizwayo ayinsimbi ephansi, ephakathi nendawo ephezulu kanye nensimbi ye-alloy ephansi efunwa kakhulu yimakethe;isivinini esikhulu sokuginqika ngu-18m/s.Inqubo yayo yokukhiqiza imi kanje:
Isithando somlilo esihambayo → isigayo esimahwaqa → isigayo esiphakathi nendawo → isigayo sokuqedela → isisetshenziswa sokupholisa amanzi → umbhede wokupholisa → ukugunda okubandayo → idivayisi yokubala okuzenzakalelayo → ibhali → indawo yokuthulula.Ifomula yokubala isisindo: ububanzi obungaphandle Х ububanzi obungaphandle Х0.00617=kg/m.
