Galvanized steel hlau yog kos los ntawm 45 #, 65 #, 70 # thiab lwm yam zoo carbon structural steel, thiab ces galvanized (electro galvanized los yog kub galvanized).
Galvanized steel hlau yog ib hom carbon steel hlau galvanized rau saum npoo los ntawm kub plating los yog electroplating.Nws cov khoom yog tib yam li cov ntawm straightened tempered steel hlau.Nws tuaj yeem siv los ua qhov tsis muaj kev sib koom ua ke, tab sis nws yuav tsum tau galvanized yam tsawg 200 ~ 300g ib square meter.Nws feem ntau yog siv los ua cov hlua khi hlua khi rau cov hlua khi hlua khi (ntxiv rau, lub tes tsho hloov tau yooj yim kuj tau siv los ua txheej txheej txheej tiv thaiv).
khoom ntiag tug
Qhov saum npoo ntawm galvanized steel hlau yuav tsum du thiab huv si tsis muaj kab nrib pleb, pob qhov rooj, pos, nti thiab xeb.Cov txheej txheej galvanized yog ib yam, muaj zog adhesion, muaj zog corrosion kuj, zoo toughness thiab elasticity.Lub zog tensile yuav tsum nyob nruab nrab ntawm 900 Mpa thiab 2200 Mpa (xaim txoj kab uas hla Φ 0.2mm- Φ 4.4 mm), tus naj npawb ntawm twists (Φ 0.5mm) rau ntau tshaj 20 zaug thiab rov khoov rau ntau tshaj 13 zaug.
Lub thickness ntawm kub-dip galvanized txheej yog 250g / m.Lub corrosion kuj ntawm steel hlau yog zoo heev txhim kho.
npaj
Galvanized steel hlau yog tsuas yog siv nyob rau hauv cog tsev cog khoom, yug me nyuam ua liaj ua teb, paj rwb ntim, caij nplooj ntoos hlav thiab hlau hlua manufacturing.Nws muaj feem xyuam rau cov txheej txheem engineering uas tsis zoo ib puag ncig ib puag ncig xws li cov kav hlau txuas txuas thiab cov kav dej phwj tuaj.
Kev kos duab
Electroplating txheej txheem ua ntej kos duab: Txhawm rau txhim kho kev ua haujlwm ntawm galvanized steel hlau, cov txheej txheem ntawm kev kos cov hlau xaim rau hauv cov khoom tiav tom qab txhuas annealing thiab galvanizing hu ua electroplating ua ntej kos duab.Cov txheej txheem raug yog: steel hlau - txhuas quenching - galvanizing - kos duab - tiav steel hlau.Ntawm cov kev kos duab ntawm galvanized steel hlau, cov txheej txheem ntawm thawj plating thiab tom qab ntawd kos duab yog cov txheej txheem luv tshaj plaws, uas tuaj yeem siv rau kub galvanizing lossis electro galvanizing thiab tom qab ntawd kos duab.Cov khoom siv hluav taws xob ntawm kub dip galvanized steel hlau tom qab kos duab zoo dua li cov hlau hlau tom qab kos duab.Ob leeg tuaj yeem tau txais ib txheej txheej nyias thiab zoo ib yam zinc, txo kev noj cov zinc thiab txo cov load ntawm cov kab galvanizing.
Cov txheej txheem kos duab tom qab nruab nrab plating: cov txheej txheem kos duab tom qab nruab nrab plating yog: steel hlau - lead quenching - thawj daim duab - zinc plating - theem nrab kos duab - tiav steel hlau.Cov yam ntxwv ntawm nruab nrab plating tom qab kos duab yog tias cov hlau lead quenched steel hlau yog galvanized tom qab kos ib zaug, thiab tom qab ntawd cov khoom tiav yog kos ob zaug.Galvanizing yog nruab nrab ntawm ob daim duab kos, yog li nws yog hu ua nruab nrab electroplating,.Cov zinc txheej ntawm cov hlau hlau ua los ntawm nruab nrab electroplating thiab tom qab ntawd kos duab yog tuab dua li uas ua los ntawm electroplating thiab tom qab ntawd kos duab.Tag nrho cov compressibility (los ntawm cov hlau lead quenching mus rau cov khoom tiav) ntawm kub-dip galvanized steel hlau tom qab electroplating thiab kos duab yog siab tshaj cov hlau hlau tom qab electroplating thiab kos duab.
Cov txheej txheem sib xyaw plating hlau: txhawm rau tsim lub zog siab zog (3000 N / mm2) galvanized steel hlau, cov txheej txheem "sib xyaw plating hlau kos duab" yuav tsum tau txais yuav.Cov txheej txheem raug yog raws li hauv qab no: txhuas quenching - thawj daim duab - pre galvanizing - theem nrab kos duab - zaum kawg galvanizing - tertiary drawing (qhuav daim duab) - tiav steel hlau tank kos duab.Cov txheej txheem saum toj no tuaj yeem tsim lub zog ultra-siab galvanized steel hlau nrog cov ntsiab lus ntawm 0.93-0.97%, txoj kab uas hla ntawm 0.26mm thiab lub zog ntawm 3921N / mm2.Thaum lub sij hawm tsim cov txheej txheem, zinc txheej tiv thaiv thiab lubricates cov hlau hlau nto, thiab cov hlau hlau yuav tsis tawg thaum lub sij hawm txheej txheem kos duab.
