304 stainless hlau phaj muaj zoo corrosion kuj thiab siab zog

304 stainless hlau phaj muaj zoo corrosion kuj thiab siab zog

Piv nrog rau cov hlau zoo tib yam, 304 stainless hlau phaj muaj qhov zoo nkauj nto, kev siv ntau yam, zoo corrosion kuj, thiab kav ntev. 304 stainless hlau phaj muaj qhov zoo corrosion kuj thiab lub zog siab, yog li nws muaj peev xwm siv tau, kub oxidation tsis kam thiab siab zog. Yog li ntawd, nws tuaj yeem ua tiav ntawm chav tsev kub thiab yooj yim rau cov txheej txheem yas.

Piv nrog rau cov hlau zoo tib yam, 304 stainless hlau phaj muaj qhov zoo nkauj nto, kev siv ntau yam, zoo corrosion kuj, thiab kav ntev.

304 stainless hlau phaj

304 stainless hlau phaj muaj qhov zoo corrosion kuj thiab lub zog siab, yog li nws muaj peev xwm siv tau, kub oxidation tsis kam thiab siab zog. Yog li ntawd, nws tuaj yeem ua tiav ntawm chav tsev kub thiab yooj yim rau cov txheej txheem yas. Vim tias nws tsis xav tau kev kho deg, nws yog qhov yooj yim, yooj yim los tswj thiab ntxuav, muaj qhov smoothness, thiab zoo weldability.

Qhov sib txawv tseem ceeb ntawm cov tshuaj muaj pes tsawg leeg ntawm 316 thiab 304 yog tias 316 muaj Mo, thiab feem ntau ntseeg tias 316 muaj kev tiv thaiv corrosion zoo dua li 304 hauv qhov chaw kub kub.

Yog li nyob rau hauv ib puag ncig kub, engineers feem ntau xaiv cov khoom ua los ntawm 316 cov khoom. Tab sis tej yam uas hu ua tsis yog kiag li. Nyob rau hauv ib puag ncig muaj zog sulfuric acid, txawm tias qhov kub siab npaum li cas, tsis txhob siv 316. Peb paub tias txhawm rau tiv thaiv cov xov los ntawm qhov kub siab, peb yuav tsum tau siv cov roj pleev xim dub.

1, Khoov txoj kev rau cov kav hlau stainless

Kub dabtsi yog khoov txoj kev: Siv ob peb lub rollers ntawm 304 stainless hlau yeeb nkab sab nraud txoj kab uas hla ncig arc tshuab dhos, thiab tom qab ntawd kho cov chais rau ntawm lub phaj hlau. Cov yeeb nkab hlau yog ntim nrog xuab zeb, thiab ob qhov kawg yog txuas nrog cov ntoo ntsaws. Cov cheeb tsam uas yuav tsum tau khoov yog rhuab thiab khoov nrog nplaim taws.

2, txheej txheem nyuaj

Kev sib txhuam ntawm cov khoom ua haujlwm thiab cov cuab yeej ua kom muaj cua sov, ua rau nws yooj yim rau hnav lub cuab yeej. Yog li ntawd, yuav tsum nruj me ntsis rau cov khoom siv, nrog rau kev hnav tsis kam thiab kub tsis kam, nrog rau kev ua tau raws li qhov yuav tsum tau ua ntawm cov ntse txiav.

Vim yog lub zog siab siv thaum txiav, kev ua haujlwm qeeb qeeb, uas ua rau muaj kev ua haujlwm tsawg. Tsis tas li ntawd, vim yog lub sijhawm kub kub, xaiv cov roj txias zoo, feem ntau yog siv sulfur chloride, muaj txiaj ntsig zoo.

3, Kev ceev faj

1. Lub luj tshib: Qhov ib txwm xav tau rau lub luj tshib puag ncig R yog lub vojvoog (centerline) ntawm lub luj tshib R yog ntau dua lossis sib npaug li 1.5 ~ 2 zaug. Yog tias R lub kaum sab xis me dhau, lub kaum sab xis ntawm cov yeeb nkab steel hlau khoov yuav ua tiaj tus. Lub kaum sab xis r ntawm tib cov yeeb nkab yuav tsum tau ua kom tau raws li qhov sib xws ntawm lub log pwm.

2. Cov txheej txheem qhov: Rau cov kav dej uas muaj kev sib txuas, cov txheej txheem tshwj xeeb yuav tsum raug txiav txim siab kom tawm vuam slag.

3. Kev ua tau zoo: 304 stainless hlau kav muaj cov yas siab thiab tawv thaum txiav, kev siv hluav taws xob siab thaum txiav, siab txiav kub, tsis tshua muaj thermal conductivity ntawm stainless hlau, tsis zoo cua sov dissipation kho, uas tuaj yeem yooj yim ua rau qhov kub thiab txias.
