Rebar izita rakajairika kune inopisa-yakakungurutswa ribbed simbi simbi.Iyo giredhi yeyakajairwa inopisa-yakatenderedzwa simbi bar ine HRB uye yakaderera goho poindi yegiredhi.H, R, uye B ndiwo mabhii ekutanga emashoko matatu, Hotrolled, Ribbed, and Bars, zvichiteerana.
Iyo inopisa-yakakungurutswa ribbed simbi simbi yakakamurwa kuita mamakisi matatu: HRB335 (yekare giredhi 20MnSi), giredhi rechitatu HRB400 (yekare giredhi 20MnSiV, 20MnSiNb, 20Mnti), uye giredhi rechina HRB500.
Kune nzira mbiri dzinowanzo shandiswa dzekuisa rebar: imwe ndeyekuisa muchikamu nechimiro chejometri, uye kurongedza kana kurongedza zvinoenderana neyakachinjika-chikamu chimiro chembabvu yakachinjika uye kuparadzaniswa kwembabvu.Type II.Uku kusarudzika kunonyanya kuratidza kubata kunobata kweiyo rebar.Yechipiri yakavakirwa padanho rekuita (giredhi), senge nyika yangu yazvino kuita chiyero, rebar iri (GB1499.2-2007) waya tsvimbo ndeye 1499.1-2008), zvinoenderana nechiyero chesimba (goho poindi / kusimba simba) Iyo rebar yakakamurwa kuita 3 mamakisi;muJapan Industrial Standard (JI SG3112), rebar yakakamurwa kuita 5 mhando maererano nekuita kwakazara;muBritish Standard (BS4461), mamakisi akati wandei erebar performance test anotsanangurwa zvakare.Pamusoro pezvo, mabhara anogona zvakare kuverengerwa zvinoenderana nekushandiswa kwawo, senge akajairwa simbi mbariro dzeakasimbiswa kongiri uye nekushisa-kupisa simbi simbi ye prestressed reinforced kongiri.
Rebar isimbi yakabatiswa simbi pamusoro, inozivikanwawo sembabvu simbi bar, kazhinji ine 2 longitudinal mbabvu uye mbabvu dzakachinjika dzakagovaniswa zvakaenzana munzira yekureba.Chimiro chembabvu yakachinjika ndeye spiral, herringbone uye crescent shape.Inoratidzwa mumamirimita ezita rechidimbu.Iyo dhayamita yezita reribbed bar inoenderana nezita rekuti dhayamita yeraundi bhaa yeakaenzana muchinjikwa-section.Iyo dhayamita yezita rebar ndeye 8-50 mm, uye inokurudzirwa madhayamita 8, 12, 16, 20, 25, 32, uye 40 mm.Ribbed simbi mbariro anonyanya kuisirwa tensile kushushikana mukongiri.Nekuda kwekuita kwembabvu, ribbed simbi mbariro vane hukuru kubatanidza kugona nekongiri, saka vanogona kumira zvirinani kuita kwemasimba ekunze.Ribbed simbi mbariro dzinoshandiswa zvakanyanya mumhando dzakasiyana siyana dzekuvaka, kunyanya dzakakura, dzinorema, dzakareruka dzakatetepa-madziro uye yakakwirira-inosimuka zvivakwa zvekuvaka.
Rebar inogadzirwa nezvigayo zvidiki.Mhando huru dzezvigayo zviduku zvinoputika ndezvi: zvinopfuurira, semi-inopfuurira uye mutsara.Zvizhinji zvezvigayo zvitsva uye-mu-kushandisa zvidiki zvinotenderedza pasi rose zvinoenderera zvizere.Akakurumbira rebar zvigayo ndezvese-chinangwa chakakwira-kumhanyisa rolling rebar mill uye 4-slice yakakwirira-yekugadzira rebar mill.
Iyo billet inoshandiswa muchigayo chidiki chinoramba chichikunguruka kazhinji chinoramba chichikanda billet, kureba kweparutivi kunowanzoita 130 ~ 160mm, kureba kunowanzoita 6 ~ 12 metres, uye imwe billet huremu i1.5 ~ 3 matani.Mazhinji emitsetse inotenderedzwa yakarongedzerwa yakatwasuka uye yakatwasuka, kuti iwane torsion-yemahara kukunguruka kuyambuka mutsara.Zvinoenderana neakasiyana mabillet akatsanangurwa uye akapedzwa saizi yechigadzirwa, kune gumi nemasere, makumi maviri, makumi maviri nemaviri, uye makumi maviri nemana madiki emagetsi, uye gumi nemasere ndiwo makuru.Bar rolling kazhinji inotora maitiro matsva senge kutsika kupisa choto, yakanyanya-kudzvanywa kwemvura kudzika, kudzika-tembiricha kutenderera, uye kusingaperi kutenderera.Rough rolling uye yepakati rolling inogadzirwa kuti ienderane nemabhiri mahombe uye kuvandudza kurongeka chaiko.Kupedzisa zvigayo zvinonyanya Kuvandudzwa kurongeka uye kumhanya (kusvika 18m/s).Madimikira echigadzirwa anowanzo ф10-40mm, uye kune zvakare ф6-32mm kana ф12-50mm.Magiredhi esimbi anogadzirwa akaderera, epakati uye akakwira kabhoni simbi uye yakaderera alloy simbi inodiwa zvakanyanya nemusika;iyo yakanyanya kumhanyisa kumhanya i18m/s.Kugadzirwa kwayo kunotevera:
Choto chokufamba → chigayo chinobvongodza → chigayo chepakati → chigayo chekupedza → mudziyo wekutonhodza mvura → mubhedha wekutonhodza → kugera kunotonhora → mudziyo wekuverenga otomatiki → bhari → chigadziko chekuburutsa.Weight calculation formula: kunze dhayamita Х kunze dhayamita Х0.00617=kg/m.
