Q: Lub ntsiab txhais ntawm SPCE steel kauj yog dab tsi?
A: SPCE yog qhov sib sib zog nqus-kos qib txias- dov carbon steel coil hauv Japanese JIS G3141 tus qauv, luv luv rau "Steel Phaj Txias Rolled rau Deep Drawing". Nws cov txiaj ntsig tseem ceeb yog plasticity siab, kev sib sib zog nqus zoo heev -kev ua tau zoo, thiab kev ua haujlwm ruaj khov, tsim tshwj xeeb rau cov txheej txheem stamping nyuaj.
Q: Dab tsi yog qhov txawv ntawm SPCE, SPCC, thiab SPCD?
A: Tag nrho peb yog cov qauv Japanese txias- dov steels. Qhov sib txawv tseem ceeb nyob hauv kev ua haujlwm: ①SPCC (qib dav dav): elongation Ntau dua lossis sib npaug li 30%, haum rau kev khoov yooj yim; ②SPCD ( qib stamping): elongation Ntau dua lossis sib npaug li 30%, haum rau kev stamping dav; ③SPCE (sib sib zog nqus- qib kos duab): elongation Ntau dua lossis sib npaug li 34%, nrog ntxiv aluminium deoxidation, muaj zog tiv thaiv kev laus, thiab tuaj yeem ua tau raws li cov kev xav tau ntawm ntau- dhau ntawm kev kos duab sib sib zog nqus.
Q: Dab tsi yog cov qauv siv rau SPCE steel kauj? A: Nws feem ntau ua raws li Japanese JIS G3141 tus qauv. Qee cov khoom xa tawm tuaj yeem ua tau raws li cov qauv thoob ntiaj teb xws li German DIN 1623-1 thiab EU EN 10130. Cov lus qhia tshwj xeeb no yuav tsum tau pom zoo rau hauv daim ntawv cog lus ua ntej.
Q: Ua li cas cov qib zoo ntawm SPCE steel coils cais?
A: Raws li JIS cov qauv, lawv tau muab faib ua qhov zoo tib yam (FA), mechanically du nto (FB), thiab precision du nto (FC). FC qib muaj qhov qis tshaj qhov roughness (Ra tsawg dua lossis sib npaug li 1.0μm), haum rau kev ua haujlwm tom ntej xws li pleev xim thiab electroplating. Qib FC feem ntau yog siv rau cov khoom siv hauv tsev thiab cov khoom siv hauv tsheb.
Q: Puas yog SPCE stainless hlau? Nws puas muaj xeb tiv thaiv?
A: Nws tsis yog stainless hlau. Nws yog qhov tseem ceeb tsawg -carbon txias- dov hlau tsis muaj xeb- tiv taus alloying ntsiab (xws li chromium thiab npib tsib xee). Nws yog nquag oxidation thiab xeb nyob rau hauv tej yam kev mob. Kev kho deg xws li galvanizing thiab pleev xim yog xav tau los txhim kho corrosion, los yog kev tiv thaiv kom zoo yuav tsum tau ua kom ntseeg tau thaum khaws cia.
