Kukho iindlela ezimbini ezisetyenziswa ngokuqhelekileyo zokuhlelwa kwe-rebar: enye kukuhlelwa ngokwemilo yejometri, kunye nokuhlelwa okanye ukuchwetheza ngokwemilo enqamlezileyo yembambo enqamlezileyo kunye nezithuba zeembambo. Uhlobo II. Olu lwahlulo lubonisa ubukhulu becala ukusebenza okubambekayo kwe-rebar. Eyesibini isekelwe kuhlelo lwentsebenzo (ibakala), njengomgangatho wokuphunyezwa kwelizwe lam ngoku, i-rebar yi (GB1499.2-2007) ucingo yi-1499.1-2008), ngokwenqanaba lamandla (inqanaba lesivuno / amandla okuqina) I-rebar i yahlulwe yangamabanga ama-3; kwiMigangatho yoShishino lwaseJapan (JI SG3112), i-rebar yahlulwe yaba ziindidi ezi-5 ngokwentsebenzo ebanzi; kuMgangatho waseBritani (BS4461), amabakala amaninzi ovavanyo lwentsebenzo yerebar nawo achaziwe. Ukongeza, ii-rebars ziyakwazi ukuhlelwa ngokokusetyenziswa kwazo, njengemivalo yentsimbi eqhelekileyo yekhonkrithi eyomeleziweyo kunye nemivalo yentsimbi egxininiswe ngobushushu kwikhonkrithi eyomeleziweyo.
I-Rebar yintsimbi yentsimbi eneembambo kumphezulu, ekwabizwa ngokuba yi-ribbed steel bar, ihlala ineembambo ezi-2 ezinde kunye neembambo ezinqamlezileyo zisasazwe ngokulinganayo kwicala lobude. Imilo yembambo enqamlezileyo i-spiral, herringbone kunye ne-crescent shape. Ibonakaliswe ngeemilimitha zedayamitha yegama. I-diameter ekhethiweyo ye-ribbed bar ihambelana nomlinganiselo oqhelekileyo we-bar ejikelezayo ye-cross-section elinganayo. I-diameter ekhethiweyo ye-rebar yi-8-50 mm, kwaye i-diameter ekhuthazwayo yi-8, 12, 16, 20, 25, 32, kunye ne-40 mm. Imivalo yentsimbi ye-Ribbed iphantsi koxinzelelo lwe-tensile kwi-concrete. Ngenxa yesenzo seembambo, imivalo yensimbi eboshiweyo inamandla okudibanisa kunye nekhonkrithi, ngoko ke inokumelana bhetele nesenzo samandla angaphandle. Imivalo yetsimbi ye-Ribbed isetyenziswa ngokubanzi kwizakhiwo ezahlukeneyo zokwakha, ngokukodwa ezinkulu, ezinzima, ezikhanyayo ezinodonga oluncinci kunye nezakhiwo eziphakamileyo.
I-Rebar iveliswa ngamancinci amancinci ajikelezayo, kwaye iindidi eziphambili zee-rolling mill zi: ziqhubekayo, zi-semi-continuous kunye ne-tandem. Uninzi lwezixhobo zokungqusha ezitsha nezisasetyenziswayo kwihlabathi ziqhuba ngokupheleleyo. Ii-rebar Mills ezidumileyo ziinjongo-jikelele ze-high-speed rolling rebar mills kunye ne-4-slice high-production rebar mills.
I-billet esetyenzisiweyo kwi-mill encinci eqhubekayo i-billet eqhubekayo yokuphosa, ubude becala ngokuqhelekileyo buyi-130 ~ 160mm, ubude ngokubanzi malunga ne-6 ~ 12 yeemitha, kunye nobunzima be-billet eyodwa yi-1.5 ~ 3 iitoni. Uninzi lwemigca eqengqelekayo icwangciswe ngokuthe tye nathe nkqo, ukuphumeza ukuqengqeleka okungagungqiyo kumgca. Ngokweenkcazo ezahlukeneyo zebillet kunye nobukhulu bemveliso egqityiweyo, kukho i-18, i-20, i-22, kunye ne-24 ye-rolling mill encinci, kwaye i-18 yeyona nto iphambili. Ukuqengqeleka kweBar ikakhulu kwamkela iinkqubo ezintsha ezinje ngokunyathela kwiziko lokufudumeza, ukuhla koxinzelelo lwamanzi aphezulu, ukuqengqeleka kobushushu obuphantsi, kunye nokuqengqeleka okungapheliyo. I-rough rolling kunye ne-intermediate rolling iphuhliswa ukulungelelanisa kwiibhilithi ezinkulu kunye nokuphucula ukuchaneka kokuqengqeleka. Ukugqiba izixhobo zokusila ubukhulu becala Ukuphuculwa kokuchaneka kunye nesantya (ukuya kuthi ga kwi-18m / s). Iinkcukacha zemveliso ziqhelekile ukuba yi-ф10-40mm, kwaye kukwakho ne-ф6-32mm okanye i-ф12-50mm. Amabakala ensimbi avelisiweyo aphantsi, aphakathi kunye nephezulu ye-carbon steel kunye nentsimbi ephantsi ye-alloy efunekayo kakhulu kwiimarike; ubuninzi besantya sokuqengqeleka yi-18m/s. Inkqubo yokuveliswa kwayo imi ngolu hlobo lulandelayo:
