Cia peb xub tau txais lub nominal phab ntsa thickness MM2.02.52.83.53.84.04.5
Tseem muaj galvanized steel yeeb nkab coefficient tsis: C1.0641.0511.0451.0401.0361.0341.0321.028
Cov hauv qab no piav qhia tias kev ua haujlwm ntawm steel hlau yog qhov tseem ceeb ntawm qhov kev ua tau zoo kawg (kev ua tau zoo ntawm cov tshuab) ntawm cov hlau. Nws nyob ntawm cov tshuaj muaj pes tsawg leeg thiab thermal kho system ntawm steel. Nyob rau hauv cov txheej txheem steel yeeb nkab, raws li kev siv sib txawv, kev ua haujlwm ncab (lub zog tensile, yield zog los yog yield point, elongation point) thiab hardness, toughness indicators, as well as high and low temperature performance by users. : Hlau tooj: Q215A; Q215B; qw 235a;. q235 ua.
Ntsuas tus nqi /MPA:D10.2-168.3mm yog 3MPa; D177.8-323.9mm yog 5MPa
Qhov saum npoo ntawm galvanized steel yeeb nkab yog vuam steel kav nrog kub-soaking lossis electro-galvanized txheej. Galvanizing tuaj yeem ua rau muaj kev tiv thaiv corrosion ntawm cov kav hlau thiab txuas ntxiv lub neej kev pab cuam. Galvanized steel kav yog dav siv. Ntxiv rau cov kav dej uas tsis tshua muaj siab xws li kev xa dej, roj, thiab roj, nws kuj tseem siv tau los ua cov kav dej roj thiab cov kav dej ntawm cov roj kev lag luam, tshwj xeeb tshaj yog cov roj hauv hiav txwv, cov roj cua sov, cov cua sov thiab cua txias ntawm cov khoom siv coking. Rau cov raj, thee distillation roj ntxhua khaub ncaws, nrog rau kev txhawb nqa cov kav dej ntawm cov kav dej nro, thiab cov mining tunnels. Kub-dip galvanized steel yeeb nkab yog dav siv nyob rau hauv ntau yam niaj hnub manufacturing industries.
Galvanized steel kav tau muab faib ua cov kav dej txias galvanized thiab kub-dip galvanized kav. Thaum pib, galvanized steel kav tau siv los ua cov kav dej. Tom qab ob peb xyoos, ib qho loj ntawm xeb tau tsim. Cov dej ntws tawm ntawm cov dej daj tsis yog tsuas yog ua rau cov khoom tu huv si, tab sis kuj sib xyaw nrog cov kab mob hauv cov phab ntsa sab hauv. Kho cov ntsiab lus hlau siab hauv dej siab dhau, uas ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv. Yog li ntawd, nyob rau xyoo 1960 thiab 1970s, cov teb chaws tsim kho tau pib tsim cov kav dej tshiab thiab cov kav hlau tsis muaj zog galvanized.
