I-rebar yigama elivamile lemigoqo yensimbi evuthayo evuthayo. Ibanga lebha yensimbi ejwayelekile eshisayo liqukethe i-HRB kanye nephuzu lesivuno esincane sebanga. H, r, no-b yizinhlamvu zokuqala zamagama amathathu, ahoxile, aphonswe, nemigoqo, ngokulandelana.
I-Barbed ekhishwe ngensimbi eshisiwe ihlukaniswe ngamabanga amathathu: I-HRB335 (ibanga elidala lingu-20mnzi), ibanga lesithathu i-HRB400 (ibanga elidala lingama-20msiv, kanye nebanga lesine le-HRB500.
I-rebar iyibha yensimbi ethosiwe ebusweni, eyaziwa nangokuthi ibha yensimbi eyi-ribbed, imvamisa enamambambo ama-2 amade kanye nezimbambo eziguqukayo ezisatshalaliswa ngokulinganayo eduze nasezingeni eliphakeme. Ukwakheka kwembambo ye-transverse kuvunguza, i-herringlone kanye nokwakheka kwe-crescent. Kuvezwe ngamamilimitha we-liminal ububanzi. Ububanzi be-audional webhari elibiwe buhambelana nobubanzi bemfihlo bebha eliyindilinga le-Equight Cross-punt. Ububanzi be-National of the rebar ngu-8-50 mm, futhi amawazi anconyiwe angama-8, 12, 16, 20, 25, 32, no-40 mm. Amabha ensimbi anamabhanoyi ikakhulukazi afakwa ngaphansi kwengcindezi ethe xaxa ngokhonkolo. Ngenxa yesenzo sezimbambo, imigoqo yensimbi enombhobho inekhono elikhudlwana le-bonding ngokhonkolo, ukuze ikwazi ukubekezelela kangcono isenzo samabutho angaphandle. Amabha ensimbi anama-ribbed asetshenziswa kabanzi ezinhlakeni ezahlukahlukene zokwakha, ikakhulukazi izinhlaka ezinkulu ezibiyelwe ngodonga ezinamakhaza aphansi.
I-rebar ikhiqizwa ngamamitha amancane okugoqa. Izinhlobo eziphambili zokugaya ama-rolling amancane yilezi: okuqhubekayo, okuqhubekayo futhi kuyahlukahluka. Iningi lamamitha amancane okugoqa amasha naphakathi emhlabeni aqhubeka ngokugcwele. I-rebar mills edumile iyinhloso-inhloso ejwayelekile yokugoqa ama-rebar mills kanye ne-4-slip rabar mills ephezulu.
I-billet esetshenziswe ku-incane yokugoqa kancane ngokuvamile i-billet eqhubekayo yokuphonsa, ubude be-main ubude bungu-160 ~ 160mm, ubude bungamamitha ayi-12, futhi isisindo esisodwa se-billet singu-1.5 ~ amathani ama-3. Iningi lemigqa yokugoqa lihlelwe ngokuqondile ngokuqondile nangokuqondile, ukufezekisa ukugoqa kwama-torssion-free ngaphesheya komugqa. Ngokusho kwemininingwane ehlukene ye-billet kanye nosayizi womkhiqizo osuqediwe, kunamamitha amancane ayi-18, 20, 22, kanye nama-24 ajwayelekile. Ukugingqa ibha kakhulu ukwamukela izinqubo ezintsha ezinjengezinyathelo ezifudumeza ukufudumeza, amanzi acindezelayo asolayo, ukugoqa okushisa okuphansi, nokugoqa okungapheli. Ukugingqa okunolaka kanye nokugoqa okuphakathi kwakha ekuqondisweni kokuzivumelanisa nezikweletu ezinkulu nasekuthuthukiseni ukunemba okuxakayo. Ukunemba okuthuthukile kanye nesivinini (kuze kufike ku-18m / s). Imininingwane yomkhiqizo ngokuvamile i-Ф10-40mm, futhi kukhona u-Ф_-32mm noma i-Фmemm. Amabanga ensimbi akhiqizwa anensimbi ephansi, ephakathi nendawo ephakeme ye-carbon nensimbi ephansi efunwa kabanzi emakethe; Ijubane elikhulu lokugibela lingu-18m / s. Inqubo yayo yokukhiqiza imi ngale ndlela elandelayo:
Ukuhamba Umlilo →I-Riging Mill → I-Intermediate Rolling Mill → Isiqeshana Sokugibela → Idivaysi Yokupholisa Amanzi → Ukupholisa Umbhede → Ukuvuselela Umbhede Ifomula yokubala isisindo: ububanzi obungaphandle х0.00617 = kg / m.
