Q: "Kev laus" txhais li cas hauv SPCE? Yuav zam tau li cas?
A: Kev laus yog hais txog qhov nce ntawm cov khoom muaj zog thiab txo qis hauv plasticity (brittleness) ntawm cov hlau tom qab lub sijhawm ntev cia. SPCE tuaj yeem ncua nws lub sijhawm laus mus rau ntau dua 6 lub hlis los ntawm kev tswj cov ntsiab lus nitrogen (N Tsawg dua lossis sib npaug li 0.008%) los ntawm txhuas deoxidation. Txoj kev zam: ① Txheej txheem sai li sai tau (cov khoom muag tsis pub dhau 3 lub hlis); ② Khaws rau hauv qhov chaw qhuav, tsis txhob hloov pauv kub.
Q: Dab tsi yog qhov ntsuas qhov ntsuas qhov tseeb muaj rau SPCE steel coils?
A: Tus qauv kam rau ua feem ntau yog JIS (piv txwv li, thickness kam rau ua ± 0.05mm). Rau precision machining, siab kam rau ua (± 0.02mm) lossis ultra- siab kam rau ua (± 0.01mm) tuaj yeem xaiv. Nws yog ib qho tsim nyog kom paub meej tias muaj peev xwm ntau lawm nrog tus neeg muag khoom ua ntej. Siab -kev ua siab ntev ntev tuaj yeem ua rau cov nqi tsim khoom thiab lub sijhawm xa tuaj.
Q: Dab tsi yog qhov hardness ntau ntawm SPCE? A: Vickers hardness (HV) 70-100, Brinell hardness (HB) 65-95, hardness uniformity Tsawg dua los yog sib npaug rau ± 5HV, haum rau kev tswj cov duab stability tom qab stamping yam tsis muaj kev kho cua sov, tsis txhob stamping tawg los ntawm ntau hardness.
Q: Dab tsi ntsuas ntsuas qhov "kev ua haujlwm tob tob" ntawm SPCE steel coils?
A: Qhov taw qhia tseem ceeb yog "tus nqi cupping (IE)". Rau lub thickness ntawm 1.0 hli, IE Ntau dua los yog sib npaug rau 10.5 hli. Tus nqi siab dua, qhov muaj zog ntawm qhov sib sib zog nqus nqus peev xwm. Tsis tas li ntawd, qhov sib piv ntawm lub zog (yield zog / tensile lub zog) Tsawg dua los yog sib npaug ntawm 0.75 kuj yuav tsum tau ua kom ntseeg tau tias cov yas deformation tsis sib xws thaum lub sij hawm stamping.
Q: Puas yog SPCE magnetic?
A: Nws muaj zog hlau nplaum (ferritic qauv). Cov hlau nplaum yuav txhim kho me ntsis tom qab stamping, khoov, thiab lwm yam kev ua, tab sis nws yuav tsis cuam tshuam rau cov txheej txheem tom ntej, electroplating, lossis lwm yam txheej txheem, thiab nws yuav tsis cuam tshuam rau kev ua haujlwm ntawm cov khoom siv hluav taws xob (xws li cov khoom siv hauv tsev).
