Tus me nyuam fecr

Fecr yog hlau alloy nrog chromium thiab hlau raws li lub ntsiab lus tseem ceeb. Nws tseem muaj cov impurities xws li carbon, silicon, sulfur, thiab phosphorus. Nws yog ib qho ntawm cov neeg sawv cev ntawm cov hlau ua haujlwm hauv kev lag luam steel thiab tau siv dav hauv metallurgy, cov khoom siv refractory, thiab kev lag luam siv tshuaj lom neeg. Nws yog cov hlau-based alloy nrog cov chromium cov ntsiab lus ntawm 50% {%, thiab lwm yam me me. Nws yog ib qho tseem ceeb ntxiv hauv kev lag luam metallurgical. Nws tuaj yeem txhim kho cov corrosion tsis kam, Hardness, thiab kub-oxidation tsis kam ntawm cov hlau. Nws tso nyiaj rau 60% -80% hauv cov hlau stainless. Nws yog tsim los ntawm kev txo cov chromium ore thiab smelting coke nyob rau hauv lub cub hluav taws xob hauv hluav taws xob. Nws muaj cov nuj nqis thiab ruaj khov sib xyaw. Nws yog siv hauv kev tsim cov khoom ntawm high-kawg corrosion-resistant cov ntaub ntawv.
Fecr yog tsim ntawm chromium thiab hlau. Nws yog smelted nyob rau hauv ib submerged arc rauv thiab muaj siab tawv, hnav tsis kam, thiab oxidation tsis kam. Nws yog siv nyob rau hauv kev tsim cov khoom lag luam stainless hlau, kub-resist hlau hlau, thiab tuam hlau. Nws tuaj yeem txhim kho cov corrosion tsis kam thiab cov tawv nqaij tawv ntawm cov hlau. Nyob rau hauv lub foundry kev lag luam, nws tuaj yeem txhim kho cov kev coj ua tsis kam thiab nyuaj ntawm castings. Nws yog cov khoom tseem ceeb rau kev lag luam steel.
Fecr alloys ua los ntawm Electro-silicon thermal txoj kev los yog nqus cov txheej txheem decarburization muaj ib qho kev sib piv chromium-hlau sib piv. High-carbon hom yog siv rau hnav-resistant cam khwb cia hlau, thiab cov hom muaj roj carbon tsawg yog siv rau ultra-ntshiab stainless hlau thiab aviation alloys. Nws tuaj yeem tsim cov chromium oxide zaj duab xis kom ncua kev xeb ntawm cov hlau, ua kom cov nplej ua kom zoo thiab txhim kho lub zog. Fecr yog cov khoom siv tseem ceeb rau cov khoom siv txheej txheem tiv thaiv corrosion, sib txuas ua ke thiab kav ntev.
