I-Rebar ligama eliqhelekileyo leentsimbi zentsimbi eziqengqelekayo. Ibakala lentsimbi yentsimbi eqhelekileyo eshushu-eqengqelekayo libandakanya iHRB kunye neyona ndawo isezantsi yesivuno somgangatho. H, R, no B ngoonobumba bokuqala bamagama amathathu, Hotrolled, Ribbed, and Bars, ngokulandelelanayo.
Intsimbi yentsimbi eshushu eqengqelekayo ihlukaniswe ngamabakala amathathu: i-HRB335 (ibakala elidala liyi-20MnSi), ibakala lesithathu i-HRB400 (ibakala elidala liyi-20MnSiV, i-20MnSiNb, i-20Mnti), kunye ne-HRB500 yesine.
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 ngamashishini amancinci aqengqelekayo. Iindidi eziphambili zee-rolling mill zincinci: ziqhubeka, zi-semi-continuous kunye nomqolo. Uninzi lwezixhobo zokungqusha ezitsha nezisasetyenziswayo kwihlabathi ziqhuba ngokupheleleyo. Ii-rebar Mills ezidumileyo zinjongo-jikelele ze-high-speed-rolling rebar mills kunye ne-4-slice high-production rebar mills.
I-billet esetyenziswe kwi-mill encinci eqhubekayo i-billet eqhubekayo yokuphosa, ubude becala ngokuqhelekileyo buyi-130 ~ 160mm, ubude ngokuqhelekileyo 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 oluphezulu lwamanzi, ukuqengqeleka kobushushu obuphantsi, kunye nokuqengqeleka okungapheliyo. I-rough rolling kunye ne-intermediate rolling iphuhlisa kwindlela yokulungelelanisa kwiibhilithi ezinkulu kunye nokuphucula ukuchaneka kwe-rolling. Ukuchaneka okuphuculweyo kunye nesantya (ukuya 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 efunwa kakhulu yimarike; ubuninzi besantya sokuqengqeleka yi-18m/s. Inkqubo yokuveliswa kwayo imi ngolu hlobo lulandelayo:
Iziko lokuhamba →ilitye lokusila eliphakathi → ilitye eliphakathi eliqengqayo → ukugqibezela ilitye lokusila → isixhobo sokupholisa samanzi → ibhedi yokupholisa → ukucheba okubandayo → isixhobo sokubala esizenzekelayo → ibhali → indawo yokukhulula. Ifomula yokubala ubunzima: idayamitha yangaphandle Х idayamitha yangaphandle Х0.00617=kg/m.
