Spcc Cov Khoom Siv Hluav Taws Xob

Cov cuab yeej ua haujlwm ntawm Spcc (feem ntau txias - rolled carbon steel ntawv thiab sawb) yog ze rau nws cov ntsiab lus roj carbon ntau thiab txias} rolling cov txheej txheem. Lawv feem ntau ua yeeb yam zoo, ua haujlwm, thiab lub zog muaj zog, ua rau lawv muaj zog siv rau kev tsim cov txheej txheem xws li txias stamping thiab khoov. Hauv qab no yog nws cov kws kho tshuab cov tshuab hluav taws xob (raug hais raws li Japanese Jis GIS GIS GIS GIS GIS GISH41):
1. Tensile Lub Zog (ulb)
Ntau yam: 270-370 MPa
Nco tseg: Lub zog tensile yog qhov kev ntxhov siab tshaj plaws uas ib cov khoom tiv thaiv pob txha lov. Spcc lub zog xob laim tensile lub zog ua kom muaj kev ruaj khov thaum ua haujlwm txias (tsis kam ua kom tiav) tsis muaj kev nyuaj zuj zus vim ntau lub zog.
2. Puture lub zog (σS)
Ntau yam: ntau dua los yog sib npaug rau 130 mpa (tsis muaj qhov txwv sab saud; feem ntau nce nrog txias- rolling deformation).
NCO TSEG: Tshaj tawm lub zog yog qhov kev ntxhov siab uas ib qho khoom siv pib yub tawg. SPCC qhov tsawg tawm lub zog ua kom nws yooj yim deformable thaum ua haujlwm txias (xws li tsim cov duab kev ua si {}} elongation (Δ)
Ntau yam: ntau dua los yog sib npaug rau 30% (rau cov ntsuas ntsuas ntsuas ntsuas ntev ntawm 50 hli)
Nco tseg: elongation yog ib qho qhia ntawm cov khoom siv lub peev xwm los plastically deform ua ntej bacture. Spcc lub siab elongation (ntau dua los yog sib npaug nrog 30%) qhia tias nws los ntxias cov nyom tensile tsis muaj kev tawg. Qhov no yog qhov tseem ceeb rau cov khaub ncaws txias thiab sib sib zog nqus cov txheej txheem (piv txwv li, cov khoom siv sib txuas ntawm cov cuab yeej siv thiab lub vaj tse tsheb).
4. Hardness
Feem ntau qhia hauv Brinell hardness (HB) lossis vickers hardness (hv):
Brinell Hardness (HB): kwv yees li 60-80 HB (nyob ntawm qhov chaw txias kom txo)
Vickers Hardness (HV): Kwv yees 70-100 HV
NCO TSEG: Spcc muaj qhov tsis muaj zog qis, tso nws rau hauv cov hlau me me. Qhov no ua rau nws haum rau kev ua haujlwm txias xws li txiav thiab stamping, thiab nws cov npoo yog yooj yim rau kev kho mob tom ntej xws li kev pleev xim thiab electroplating. Zais Cov Lus Qhia
Cov khoom siv tshuab hluav taws xob ntawm SPCC muaj kev cuam tshuam los ntawm cov txheej txheem dov txias (xws li txo thiab annealing):
Qhov ntau dua qhov txias txias rolling deformation, ntau dua cov khoom siv lub zog (tensile lub zog, tawm lub zog) thiab qis dua nws cov plasterity (elongation).
Annealing txo lub zog thiab txuas ntxiv ntxiv cov yas, ua rau nws haum ntau rau siab {{0} precision sib sau.
Daim Ntawv Thov Qhov Tseeb
Spcc cov cuab yeej kho tshuab ua kom nws dav siv hauv cov ntawv thov thiab cov haujlwm muaj zog, xws li:
Automotive ntu (cov twj paj nruag panels, lub qhov rooj sab panels);
Cov khoom siv hauv tsev (tub yees thiab tshuab ntxhua khaub ncaws panels);
Kho vajtse (teeb pom kev zoo, nkhaus);
Nyiaj basingings (ntau yam complex nyias -}} cov kab ntawm phab ntsa);
Hauv ntej, nrog nws cov tub ntxhais kho tshuab cov yam ntxwv ntawm "tsis muaj zog thiab muaj txiaj ntsig zoo," Spcc yog tus nqi yooj yim heev rau kev ua haujlwm txias.
