Cov txheej txheem ntawm Weathering Steel Phaj

Weathering steel, uas yog, atmospheric corrosion resistant steel, yog ib tug series ntawm low-alloy steel ntawm zoo tib yam hlau thiab stainless hlau, weathering phaj yog ua los ntawm cov pa roj carbon zoo tib yam nrog ib tug me me tooj liab, npib tsib xee thiab lwm yam corrosion-resistant ntsiab, huab cua. tsis kam yog 2 ~ 8 npaug ntawm cov pa roj carbon zoo tib yam, txheej yog 1.5 ~ 10 npaug ntawm cov pa roj carbon zoo tib yam.

Weathering steel yog qhov paub zoo tshaj plaws rau cov ntawv luv "Corrosion resistance" thiab "Tensile zog" thiab lub npe lag luam "COR-TEN", yog li cov lus Askiv feem ntau hu ua "Corten Steel" raws li huab cua steel. Tsis zoo li cov hlau tsis muaj hlau, uas tsis tuaj yeem xeb tag nrho, huab cua hlau tsuas yog oxidizes ntawm qhov chaw thiab tsis nkag mus rau hauv qhov tob, nrog kev tiv thaiv corrosion zoo li tooj liab lossis txhuas.

Vim li cas thiaj tuaj yeem tiv taus steel xeb tsis muaj rot?
Weathering steel, tsis zoo li cov hlau tsis tu ncua, kuj xeb ntawm qhov chaw ib yam li cov hlau tsis tu ncua thaum pib. Vim nws cov qib siab ntawm alloying, cov txheej txheem no tseem nrawm dua li cov hlau tsis tu ncua. Txawm li cas los xij, vim tias cov lattice nyob rau hauv cov huab cua huab cua yog qhov nyuaj dua, cov xim dub dub ntom ntom txheej yuav loj hlob hauv qab xoob xeb ntawm qhov chaw. Nyob rau hauv no ntom ntom txheej, npib tsib xee atoms muab qhov chaw ntawm ib co hlau atoms, ua cov xeb txheej cationically xaiv thiab resistant rau corrosive anion nkag.

Nws yog txheej txheej ntom ntom ntom uas ua rau cov huab cua steel xeb ntawm qhov chaw, tab sis sab hauv yuav tsis xeb ntxiv. Qhov tseeb, tsuav yog koj ua tib zoo paub qhov txawv, koj tuaj yeem pom tias qhov saum npoo ntawm cov hlau tsis zoo ib yam li cov xeb zoo tib yam: cov xeb ntawm cov hlau tsis zoo thiab ntom, thiab nws tiv thaiv cov hlau ze ntawm cov hlau; Xwb, ntawm qhov tod tes, yog mottled, xoob thiab ntxeem tau, thiab yuav poob thaum kov.

Weathering steel phaj manufacturing txheej txheem
Weathering steel phaj feem ntau txais kev mloog zoo rau hauv qhov cub-smelting (converter, hluav taws xob rauv - microalloying kev kho mob-argon tshuab-LF refining-tsawg superheat nruam casting (feem tsawg lub ntiaj teb hlau)-tswj dov thiab txias tswj thiab lwm yam txheej txheem. cov hlau seem yog ntxiv rau lub cub tawg nrog cov nqi, smelted raws li cov txheej txheem, thiab cov deoxidizer thiab alloy ntxiv tom qab cov hlau tso tawm, thiab cov hlau molten yog kho los ntawm argon tshuab, thiab tom qab ntawd casting, thiab cov hlau molten tom qab. argon tempering yog cam khwb cia rau hauv ib lub slab los ntawm lub nruam casting tshuab.Vim qhov sib ntxiv ntawm lub ntiaj teb tsis tshua muaj cov ntsiab lus rau cov hlau, cov huab cua steel phaj yog purified, thiab cov ntsiab lus suav nrog txo qis heev.

Kev siv cov cua sov steel
Weathering steel yog tsuas yog siv nyob rau hauv steel lug siv nyob rau hauv railways, tsheb, txuas hniav, yees, photovoltaics, high-ceev tej yaam num thiab lwm yam ntev raug rau cov huab cua. Nws tseem tuaj yeem siv los tsim cov ntim khoom, tsheb ciav hlau, roj derricks, seaport cov tsev, cov chaw tsim roj thiab cov thawv uas muaj cov tshuaj sulfur corrosion media hauv cov khoom siv roj av. Tsis tas li ntawd, vim nws qhov tshwj xeeb zoo li, weathering steel kuj feem ntau siv hauv pej xeem kos duab, duab puab sab nraum zoov thiab lub tsev kho kom zoo nkauj façade.
