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 lingu-20MnSi), ibanga lesithathu i-HRB400 (ibanga elidala ngu-20MnSiV, 20MnSiNb, 20Mnti), kanye nebanga lesine i-HRB500.
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 kwamabha ngokuvamile kusebenzisa izinqubo ezintsha ezifana nezitebhisi zokushisa, ukwehla kwamanzi anomfutho ophezulu, ukuginqika okunethempelesha eliphansi, nokuginqika okungapheli. Ukugingqika okungalungile nokuginqika okuphakathi kuyathuthuka ngendlela yokujwayela amabhilidi amakhulu kanye nokwenza ngcono ukunemba kokugoqa. Ukunemba okuthuthukisiwe 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 emakethe; isivinini esikhulu sokuginqika ngu-18m/s. Inqubo yayo yokukhiqiza imi kanje:
Isithando somlilo esihambayo →umshini wokugaya → umshini wokugaya ophakathi nendawo → umshini wokuqedela → umshini wokupholisa amanzi → umbhede wokupholisa → ukugunda okubandayo → idivayisi yokubala okuzenzakalelayo → ibhali → indawo yokuthulula. Ifomula yokubala isisindo: ububanzi obungaphandle Х ububanzi obungaphandle Х0.00617=kg/m.
