Cov khoom siv steel phaj yog qhov qubcarbon steel phaj, stainless hlau, high-speed steel, siab manganese steel thiab lwm yam. Lawv cov khoom tseem ceeb yog cov hlau molten, uas yog cov khoom siv los ntawm cov hlau uas tau nchuav tom qab txias thiab tom qab ntawd nias mechanically. Feem ntau ntawm cov hlau phaj yog tiaj tus los yog cov duab plaub, uas tuaj yeem tsis tsuas yog cov tshuab nias, tab sis kuj txiav nrog lub dav hlau sawb.
Yog li dab tsi yog hom steel phaj?
Classification los ntawm thickness
(1) nyias phaj: thickness <4 mm
(2) Nruab nrab phaj: 4 mm ~ 20 mm
(3) Phaj tuab: 20mm ~ 60mm
(4) Cov phaj tuab ntxiv: 60 hli ~ 115 hli
Muab faib los ntawm txoj kev tsim khoom
(1)Kub dov steel phaj: Qhov saum npoo ntawm cov txheej txheem kub khi muaj oxide daim tawv nqaij, thiab cov phaj tuab muaj qhov sib txawv qis dua. Kub dov steel phaj muaj tsawg hardness, yooj yim ua thiab zoo ductility.
(2)Cold dov steel phaj: tsis muaj oxide daim tawv nqaij ntawm qhov chaw ntawm kev ua haujlwm txias, zoo zoo. Lub phaj txias-kuav los tiag muaj siab hardness thiab kuj nyuaj ua, tab sis nws tsis yooj yim rau deform thiab muaj zog siab.
Classified los ntawm nto nta
(1)Galvanized ntawv(cov ntawv kub galvanized, Electro-galvanized ntawv): Txhawm rau tiv thaiv qhov saum npoo ntawm cov hlau phaj los ntawm kev corroded kom ntev nws cov kev pab cuam lub neej, qhov saum npoo ntawm cov hlau phaj yog coated nrog ib txheej ntawm hlau zinc.
Kub dip galvanizing: nyias steel phaj yog immersed nyob rau hauv lub melted zinc tank, kom nws nto adheres rau ib txheej ntawm zinc nyias steel phaj. Tam sim no, nws yog tsim los ntawm cov txheej txheem txuas ntxiv galvanizing, uas yog, txuas ntxiv mus rau ntawm cov hlau phaj hauv melting zinc plating tank los ua galvanized steel daim hlau.
Electro-galvanized sheet: Cov galvanized steel phaj ua los ntawm electroplating muaj kev ua haujlwm zoo. Txawm li cas los xij, cov txheej txheej yog nyias thiab qhov kev tiv thaiv corrosion tsis zoo li cov ntawv kub-dip galvanized.
(2) Tinplate
(3) Composite steel phaj
(4)Xim coated steel phaj: feem ntau hu ua xim hlau phaj, nrog cov zoo txias-kuav los tiag steel phaj, kub-dip galvanized steel phaj los yog aluminized zinc steel phaj raws li substrate, tom qab degreasing degreasing, phosphating, chromate kho thiab hloov dua siab tshiab, coated nrog organic txheej tom qab ci. .
Nws muaj cov yam ntxwv ntawm lub teeb yuag, siab zog, ci xim thiab zoo durability. Siv dav hauv kev tsim kho, khoom siv hauv tsev, kho kom zoo nkauj, tsheb thiab lwm yam.
Kev faib tawm los ntawm kev siv
(1) Choj steel phaj
(2) Boiler steel phaj: dav siv hauv roj av, tshuaj, chaw nres tsheb fais fab, boiler thiab lwm yam lag luam.
(3) Shipbuilding steel phaj: nyias steel phaj thiab tuab steel phaj tsim nrog shipbuilding tshwj xeeb structural steel rau kev tsim cov qauv ntawm lub hiav txwv-mus, ntug hiav txwv dej thiab inland navigation ships.
(4) Armor phaj
(5) Tsheb steel phaj:
(6) Lub tsev steel phaj
(7) Cov qauv steel phaj:
(8) Hluav taws xob steel phaj (silicon steel ntawv)
(9) Lwm tus
Peb muaj ntau tshaj li 17 xyoo ntawm kev nplua nuj nyob rau hauv cov hlau, peb cov neeg muas zaub nyob rau hauv Tuam Tshoj thiab ntau tshaj 30 lub teb chaws thiab cheeb tsam nyob ib ncig ntawm lub ntiaj teb no, xws li lub tebchaws United States, Canada, Australia, Malaysia, Philippines thiab lwm lub teb chaws, peb lub hom phiaj yog los muab cov khoom lag luam zoo steel rau cov neeg siv khoom thoob ntiaj teb.
Peb muab cov khoom lag luam sib tw tshaj plaws los xyuas kom meej tias peb cov khoom zoo tib yam raws li tus nqi zoo tshaj plaws, peb kuj muab cov neeg siv khoom sib sib zog nqus ua lag luam. Rau feem ntau cov lus nug thiab cov lus hais, tsuav yog koj muab cov ncauj lus kom ntxaws thiab qhov yuav tsum tau muaj, peb yuav muab lus teb rau koj hauv ib hnub ua haujlwm.
