Pali njira ziwiri zodziwika bwino za rebar: imodzi imatengera mawonekedwe a geometric, omwe amagawidwa kapena kugawidwa molingana ndi mawonekedwe amtundu wosiyanasiyana komanso kusiyana kwa nthiti.Mwachitsanzo, mu British Standard (BS4449), rebar imagawidwa mu mtundu I ndi mtundu II.Gululi limawonetsa magwiridwe antchito azitsulo zopunduka.Chachiwiri, malinga ndi kagulu ka ntchito (kalasi), mwachitsanzo, mulingo wapano wa dziko lathu, rebar ndi (G B1499.2-2007) ndi ndodo ya waya ndi 1499.1-2008), rebar imagawidwa m'magawo atatu. magiredi molingana ndi mulingo wa mphamvu (zokolola zokolola / kulimba kwamphamvu);Malinga ndi muyezo wamakampani aku Japan (JI SG3112), rebar imagawidwa m'magulu asanu malinga ndi momwe ilili;British Standard (BS4461) imatchulanso magiredi angapo oyesa magwiridwe antchito azitsulo zopunduka.Kuphatikiza apo, rebar imathanso kugawidwa molingana ndi cholinga chake, monga rebar wamba ya konkire yolimbitsa ndi rebar yotenthetsera konkriti yolimba.
Mipiringidzo yachitsulo yopunduka imagawidwa kukhala zitsulo wamba zotentha zotentha komanso zitsulo zopindika bwino.Malinga ndi tanthawuzo la muyezo, zitsulo zachitsulo zotentha zotentha ndizitsulo zomwe zimaperekedwa muzitsulo zotentha.Mapangidwe ake a metallographic amapangidwa makamaka ndi ferrite ndi pearlite, ndipo sipadzakhalanso dongosolo lina lomwe limakhudza magwiridwe antchito.Chitsulo chachitsulo chosungunuka bwino chimatanthawuza chitsulo chopangidwa ndi kugudubuza koyendetsedwa ndi kuzizira kozizira panthawi yotentha.Kapangidwe kake kazitsulo kamakhala kopangidwa ndi ferrite ndi pearlite, ndipo sipadzakhalanso mawonekedwe ena okhudza magwiridwe antchito, ndipo kukula kwambewu sikuyenera kukhala kokulirapo kuposa Giredi 9.
Gawo lazitsulo wamba wamba wopindika ndi nthiti wamba wopangidwa ndi HRB, kufunikira kwa mphamvu zokolola ndi chizindikiro chotsutsa zivomezi (+E);Gulu lazitsulo zopindika bwino zopindidwa ndi nthiti zotentha zimapangidwa ndi HRBF, kufunikira kwa mphamvu zokolola komanso chizindikiro chotsutsa zivomezi (+E);F ndi chilembo choyamba cha Fine.Wamba otentha adagulung'undisa zitsulo bala kalasi amagawidwa m'magulu asanu: HRB400, HRB500, HRB600, HRB400E ndi HRB500E;Mipiringidzo yazitsulo zazitsulo zotentha zotentha zotentha zimagawidwa kukhala HRBF400, HRBF500, HRBF400E ndi HRBF500E.
Screw thread steel imagwiritsidwa ntchito kwambiri pomanga zomangamanga monga nyumba, milatho ndi misewu.Kuyambira misewu yayikulu, njanji, milatho, ma culverts, tunnel, kuwongolera kusefukira kwamadzi, madamu ndi malo ena aboma, mpaka maziko, mizati, mizati, makoma, mbale, ndi mipiringidzo ya nyumba ndi nyumba ndi zida zofunika kwambiri zomangira.Pakalipano, zitsulo zazitsulo za HRB400 kapena HRB400E zakhala zikugwiritsidwa ntchito kwambiri padziko lonse lapansi.Kampani yathu imatha kusintha HRB500, HRB600 ndi mipiringidzo ina yachitsulo yamphamvu kwambiri.
Miyezo ya rebar yomwe kampani yathu imatha kupereka
