STAINLESS STEEL yog dab tsi?

STAINLESS STEEL yog dab tsi?

Stainless hlau yog hlau thiab chromium alloy. Txawm hais tias stainless hlau yuav tsum muaj tsawg kawg yog 10.5% chromium, cov ntsiab lus thiab qhov sib piv yuav txawv raws li qib uas tau thov thiab kev siv cov hlau.

YUAV UA LI CAS STAINLESS STEEL

Cov txheej txheem tseeb rau qib stainless hlau yuav txawv nyob rau theem tom ntej. Qib ntawm cov hlau zoo li cas, ua haujlwm thiab ua tiav ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab seb nws zoo li cas thiab ua tau zoo.

Ua ntej koj tuaj yeem tsim cov khoom siv hlau xa tuaj, koj yuav tsum xub tsim cov molten alloy.

Vim qhov no feem ntau cov qib steel sib koom ua cov kauj ruam pib.

Kauj Ruam 1: Melting

Kev tsim cov hlau tsis muaj steel pib nrog melting seem hlau thiab cov khoom ntxiv hauv hluav taws xob arc rauv (EAF). Siv cov hluav taws xob hluav taws xob siab, EAF ua kom sov cov hlau nyob rau ntau teev los tsim kom muaj cov kua dej sib tov.

Raws li stainless hlau yog 100% recyclable, ntau stainless xaj muaj ntau npaum li 60% recycled steel. Qhov no yuav pab tsis tau tsuas yog tswj cov nqi tab sis txo kev cuam tshuam ib puag ncig.

Qhov kub thiab txias yuav txawv raws li qib ntawm cov hlau tsim.

Kauj Ruam 2: Tshem tawm cov ntsiab lus carbon

Cov pa roj carbon monoxide pab ua kom lub zog thiab lub zog ntawm cov hlau. Txawm li cas los xij, carbon ntau dhau tuaj yeem tsim teeb meem-xws li carbide nag lossis daus thaum vuam.

Ua ntej casting molten stainless hlau, calibration thiab txo cov ntsiab lus ntawm cov pa roj carbon monoxide yog qhov tseem ceeb.

Muaj ob txoj hauv kev tsim cov khoom lag luam tswj cov ntsiab lus carbon.

Thawj yog los ntawm Argon Oxygen Decarburization (AOD). Txhaj tshuaj argon roj sib tov rau hauv cov hlau molten txo cov ntsiab lus carbon nrog tsawg tsawg ntawm lwm yam tseem ceeb.

Lwm txoj kev siv yog Nqus Oxygen Decarburization (VOD). Nyob rau hauv txoj kev no, molten steel yog pauv mus rau lwm lub chamber qhov twg oxygen yog txhaj rau hauv cov hlau thaum tshav kub kub. Lub tshuab nqus tsev ces tshem tawm cov pa roj tawm ntawm lub chamber, ntxiv txo cov ntsiab lus carbon.

Ob txoj hauv kev muab kev tswj xyuas cov ntsiab lus ntawm cov pa roj carbon monoxide kom ntseeg tau tias muaj kev sib xyaw kom zoo thiab cov yam ntxwv tseeb hauv cov khoom siv stainless hlau kawg.

Kauj ruam 3: Tuning

Tom qab txo cov pa roj carbon, qhov kawg ntsuas thiab homogenization ntawm kub thiab chemistry tshwm sim. Qhov no ua kom ntseeg tau tias cov hlau ua tau raws li qhov yuav tsum tau ua rau nws cov qib npaj thiab tias cov hlau muaj pes tsawg leeg zoo ib yam thoob plaws hauv pawg.

Cov qauv raug kuaj thiab tshuaj xyuas. Kev hloov kho yog ua kom txog thaum sib tov ua tau raws li tus qauv xav tau.

Kauj Ruam 4: Ua los yog Casting

Nrog cov hlau molten tsim, lub foundry yuav tsum tam sim no tsim cov qauv qub siv los ua kom txias thiab ua haujlwm cov hlau. Cov duab thiab qhov ntev yuav nyob ntawm qhov khoom kawg.
