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.
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 madiki uye akapedzwa saizi yechigadzirwa, kune 18, 20, 22, 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 iri kusimukira munzira yekuchinjika kumabhiriji makuru uye kugadzirisa kurongeka chaiko.Kuvandudzwa kwechokwadi uye nekukurumidza (kusvika ku18m / 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:
Kufamba choto →chigayo chinobvongodza → chigayo chepakati → chigayo chekupedza → chigayo chekutonhodza mvura → mubhedha wekutonhodza → kugera kunotonhora → chigayo chekuverenga otomatiki → chigayo → chigadziko chekuburutsa.Weight calculation formula: kunze dhayamita Х kunze dhayamita Х0.00617=kg/m.
