PC steel hlau
01
Prestressed Concrete Steel Hlau ntawm Indented (PC STEEL WIRE / PC WIRE)
Specifications Taw Qhia
Nws yog tsim los ntawm high carbon steel nrog ib txoj kab uas hla thiab tensile lub zog.Siv cov txheej txheem txias-kos duab, uas ua rau ib tug du nto nrog indentations tsim los ntawm ib tug cais indenting txheej txheem. PC hlau ntawm Indented / Serrated PC hlau uas yog ib hom prestressed pob zeb steel hlau uas yog tsim nrog indentations hom nyob rau hauv thiaj li yuav txhim khu kev sib raug zoo ntawm steel hlau thiab kev tsim vaj tse, kom muaj zog tuav ntawm cov pob zeb thiab hlau. xaim thiab ntxiv dag zog rau cov vaj tse pob zeb.
Qhov zoo
Nrog mechanical interlock nrog cov pob zeb, txhim kho cov qauv kev ua tau zoo thiab durability ntawm cov khoom siv ntxiv dag zog.
Nrog zoo daim ntawv cog lus zog rau cov qauv uas txhim kho.
Nrog kev tswj kom meej qhov ntev thiab qib siab ntawm qhov huv si, thaum lub indentations lav cov khoom zoo heev nrog pob zeb.
Nrog rau ntau theem ntawm daim ntawv cog lus lub zog, txhua yam khoom thiab corrosion kuj nyob rau hauv thiaj li yuav xaiv qhov zoo tshaj plaws kev daws teeb meem rau ib puag ncig tej yam kev mob thiab tej yam ntxwv yuav tsum tau.
Raw Material Requirements
Cov ntaub ntawv tseem ceeb rau cov pob zeb prestressed yog cov zoo carbon steel hlau rods ntawm SWRH77B los yog SWRH82B, lub ntsiab yuav tsum tau rau cov hlau rods yog: loj, puab, hnyav thiab tso cai sib txawv, qib thiab tshuaj muaj pes tsawg leeg, smelting txoj kev, lub xeev tus me nyuam, txhua yam khoom. , decarbonization txheej, micro-structure, nto zoo thiab cov kev cai tshwj xeeb, thiab lwm yam.
Txias yog tswj los ntawm Sterem thev naus laus zis uas yog siv los ua kom tiav ntau dua 85% Sotenization tus nqi. Feem ntau, cov coil ua raws li cov txheej txheem ib txwm muaj tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm prestressed qhob steel hlau thiab steel strand.
Ntau yam ntawm Hlau Diameter:
3.0mm-10.0 hli.
Ntau yam ntawm lub zog:
1470MPa - 1860MPa
Cov qauv ntawm Hlau Hlau rau Prestressed Qhob
Cov qauv tam sim no yog GB / T5223-2014 "Prestressed qhob steel hlau", raws li ASTM A421 / A421M, ASTM A881 / A881M -2005, BS5896-2012, PrEN10138-2: 2009, GOST 7348-813. 136-004-2003, DSTU ISO 6934-2, GOST 7348-81, DSTU ISO 6934 - 2, ABNT NBR 7482: 2008, thiab lwm yam.
Mechanical Properties
Daim ntawv thov ntawm steel hlau rau prestressed pob zeb muaj xws li ib-storey tsev thiab ntau-storey tsev, txoj kev loj thiab railway choj, pw tsaug zog, hluav taws xob ncej, siab twj tso kua mis, cia tank, thiab dej yees. Nthuav mus rau niaj hnub high-sawv vaj tse, underground vaj tse, high-rise lug, hydraulic vaj tse, marine lug, tshav dav hlau cov tsev (khiav thiab davhlau ya nyob twg), siab hlab ntsha ntawm nuclear fais fab nroj tsuag, thiab lwm yam ... Ntau yam industries, xws li super -siab, super-span, super-volume, super-loj cheeb tsam, thiab tshaj qhov hnyav load, nyob rau hauv ntau yam duab thiab txawv zog ntawm structural engineering.
