JIS G 3125 SPA-H steel phajyog ib qho kub -rolled atmospheric corrosion resistant steel, feem ntau cais raws li weathering steel (Corten steel).
Piv nrog rau cov pa roj carbon steel (nrog lossis tsis muaj tooj liab ntxiv), SPA-H steel muaj qhov ua tau zoo tshaj plaws rau atmospheric corrosion nyob rau hauv feem ntau qhov chaw sab nraum zoov.
Thaum raug huab cua thiab noo noo, SPA-H steel tsim ib txheej txheej tuab thiab xeb (patina) ntawm nws qhov chaw. Cov patina no ua raws li kev tiv thaiv kev tiv thaiv, ua kom qeeb ntxiv corrosion thiab tshem tawm qhov xav tau rau cov txheej txheej ntxiv xws li xim lossis galvanizing.

Hauv kev tsim hluav taws xob thiab chaw tsim khoom lag luam, SPA-H daim hlau feem ntau siv rau hauv cov cua preheaters, cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob, vim tias lawv tiv taus cov av noo, qhov kub thiab txias - qhov chaw hloov pauv thiab tsim kom muaj kev tiv thaiv patina uas ua rau cov khoom poob qis.
Cov hlau tseem siv dav hauv kev tsheb ciav hlau, dov khoom, thiab cov khoom siv thauj mus los, qhov twg nws tiv thaiv los nag, daus, thiab huab cua muaj kuab paug pab txuas ntxiv kev pab cuam lub neej thiab txo qis kev rov ua dua.
Tsis tas li ntawd, SPA-H yog cov khoom pov thawj rau cov thawv ntim khoom thiab cov txheej txheem sab nraum zoov, muab kev tiv thaiv corrosion txhim khu kev qha thaum lub sijhawm ntev - raug rau huab cua sib txawv. Nws tus cwj pwm huab cua uas xav tau, kev saib xyuas tsis zoo, thiab lub neej ua haujlwm ntev ua rau SPA-H yog qhov kev xaiv pheej yig thiab ruaj khov rau cov haujlwm tsim los rau ntau xyoo ntawm kev ua haujlwm sab nraum zoov.
Steel Qeb ntawm JIS G 3125 SPA-H
SPA-H belongs rau Corten steel / weathering steel qeb.
"Cor-Ten" yog ib lub cim lag luam tsim los ntawm Tebchaws Meskas Steel, xa mus rau cov hlau uas ua ke nrog corrosion kuj (Cor) thiab tensile zog (Ten).
Weathering steels zoo li SPA-H tau tsim los txo lossis tshem tawm qhov xav tau ntawm cov txheej txheem tiv thaiv, tso siab rau lawv cov txheej txheem xeb los tiv thaiv.

Q1: Dab tsi yog SPA-H Corten steel?
SPA-H yog cov txheej txheem Nyij Pooj huab cua hlau qib uas tau teev tseg hauv JIS G 3125. Nws muaj cov ntsiab lus alloying xws li tooj liab, chromium, thiab npib tsib xee, uas tso cai rau nws los tsim cov txheej txheem tiv thaiv xeb ntawm qhov chaw. Qhov patina no ua rau qeeb ntxiv corrosion thiab txhim kho ntev -lub sij hawm durability nyob rau hauv atmospheric ib puag ncig.
Q2: Dab tsi yog qhov zoo ntawm SPA-H weathering steel?
Cov txiaj ntsig tseem ceeb ntawm SPA-H steel suav nrog kev ua haujlwm zoo ntawm huab cua corrosion, siab zog, thiab tus nqi tu qis. Tsis zoo li cov pa roj carbon zoo tib yam, SPA-H tsis tas yuav tsum tau pleev xim ntau dhau los yog txheej txheej, uas yuav pab txo qis cov nqi ntawm lub neej thaum tuav lub cev zoo nkauj.
Q3: SPA -H Corten steel feem ntau siv nyob qhov twg?
SPA-H hlau yog dav siv nyob rau hauv cov txuas hniav, lub tsev cov qauv, architectural façades, railway carriages, ntim, cua preheaters, thiab economizers. Nws yog qhov tshwj xeeb tshaj yog tsim rau cov qauv sab nraum zoov uas raug hloov pauv huab cua rau lub sijhawm ntev.
Q4: Puas yog SPA-H steel xav tau kev pleev xim lossis kho qhov chaw?
Hauv feem ntau cov ntawv thov sab nraum zoov, tsis tas yuav tsum tau pleev xim ntxiv. SPA-H ib txwm tsim txheej txheej xeb ruaj khov tom qab raug rau qhov chaw. Txawm li cas los xij, nyob rau hauv ib puag ncig corrosive heev (xws li marine los yog siab - thaj chaw ntsev), ntxiv kev tiv thaiv saum npoo tuaj yeem raug pom zoo kom txuas lub neej ua haujlwm.
Q5: Nws siv sijhawm ntev npaum li cas rau SPA-H steel los tsim patina ruaj khov?
Nyob rau hauv cov huab cua ib puag ncig, SPA-H steel feem ntau tsim cov patina ruaj khov hauv 6 txog 24 lub hlis
