Q: Dab tsi yog "SPCC" hauv SPCC steel tshwj xeeb txhais tau li cas?
A: SPCC yog qhov kev xaiv rau txias- dov qis- carbon steel phaj hauv Japanese JIS G 3141 tus qauv. Cov tsiaj ntawv sawv cev rau S (Steel), P (Plate), C (Cold Rolled), thiab C (Kev Lag Luam Qib), sawv cev rau "kev lag luam zoo ib yam- qib txias- dov steel phaj." Qhov kev xaiv no tom qab tau txais los ua qhov sib npaug hauv Suav GB / T 11253 tus qauv.
Q: Dab tsi yog cov qauv tseem ceeb rau SPCC steel?
A: Muaj ob tus qauv tseem ceeb: ① Tuam Tshoj tus GB/T 11253 "Cold-rolled Steel Sheet thiab Sawb"; thiab ② Nyiv JIS G 3141 "Cold-rolled Carbon Steel Sheet thiab Sawb." Qhov sib xyaw thiab cov cuab yeej cuab tam rau SPCC nyob rau hauv ob qho tib si qauv yog qhov tseem ceeb tib yam, ua rau lawv hloov pauv tau.
Q: Dab tsi yog qhov txawv ntawm SPCC steel thiab Q235 steel?
A: Cov kev sib txawv tseem ceeb nyob hauv kev ua cov thev naus laus zis thiab kev ua haujlwm ntawm qhov chaw: SPCC yog txias - dov, tsom rau saum npoo tiav thiab cov qauv tsim, thiab yog siv rau stamping thiab kho vajtse. Q235 yog kub- dov (qee qhov txias- dov Q235 yog qib derivative), hais txog kev nruj thiab lub zog, nrog lub zog tawm ntawm 235 MPa, thiab yog siv rau cov khoom siv (xws li brackets thiab rhawv).
Q: Puas muaj cov qib tshiab thiab qub SPCC? Puas muaj lwm cov qhab nia?
A: Tsis muaj cov qib tshiab lossis qub, tab sis muaj cov qib sib npaug: EU EN tus qauv sib haum rau DC01, US ASTM tus qauv sib raug rau CS Hom B, thiab Korean KS tus qauv sib haum rau SPCC (raws li JIS). Thaum yuav khoom, koj tuaj yeem hloov pauv raws li lub hom phiaj kev lag luam tus qauv.
Q: Puas yog SPCC suav tias yog "tsawg- carbon steel"? Cov pa roj carbon ntau npaum li cas?
A: Nws yog cov pa roj carbon tsawg tsawg nrog cov ntsiab lus carbon tsawg dua lossis sib npaug li 0.15% (GB / T 11253 yuav tsum tau). Vim cov ntsiab lus tsis tshua muaj carbon, nws muaj qhov zoo weldability thiab formability, tab sis nws hardness thiab lub zog yog qis dua nruab nrab thiab siab carbon steels.
