1.Dab tsi yog cov ntsiab lus tseem ceeb tom qab kev faib cov qib hardness ntawm txias-rolled coils?
Qhov ntau dua qhov annealing, cov khoom siv softer (tsim rau kev sib sib zog nqus nqus); Qhov ntau dua qhov txias dov deformation los yog tsis muaj annealing, lub hardness ntau dua (tsim rau qhov yooj yim bending los yog cov yam ntxwv qhov chaw).
2.Yuav ua li cas cov qauv categorized nyob rau hauv Tuam Tshoj lub metallurgical kev lag luam?
Ntxiv mos: Siv rau kev sib sib zog nqus kos duab tshwj xeeb.
Mos: Siv rau kev sib sib zog nqus stamping
Semi- mos: Siv rau kev stamping
Tsawg hardness: Siv rau kev machining
Txias-hardened: tsis muaj annealing, nyuaj heev, tsuas yog haum rau kev khoov yooj yim.
3.Yuav ua li cas stamping kev ua tau zoo raws li tus qauv qub Suav teb?
Z-qib (Deepest Drawing): Softest, siab tshaj elongation.
S-qib (Drawing tob): Nruab nrab.
P-qib (Kev kos duab dav dav): Nyuaj heev.
4.Yuav ua li cas kom paub meej tus qauv?
Tshawb xyuas daim ntawv pov thawj zoo lossis qib lus kawg ntawm qhov txias -rolled coil koj muaj. Yog tias nws yog SPCC-1, nws txhais tau tias nyuaj; SPCC-8 txhais tau tias 1/8 nyuaj; SPCC-A txhais tau hais tias cov khoom muag muag.
5.Yuav ua li cas kuaj nyias daim hlau?
Yog tias daim ntawv thickness tsawg dua 1.5 hli, nws tsis pom zoo kom ntsuas HRB ncaj qha (raws li cov nyhuv anvil tuaj yeem ua rau muaj txiaj ntsig zoo). Hloov chaw, nto Rockwell hardness (HR15T / HR30T) lossis Vickers hardness (HV) yuav tsum tau siv rau kev lees paub.
