SPCC DC01 St12 Tag Nrho Cov Txias Rolled Steel Sheet Sawb Chev

Dab tsi yog qhov tseem ceeb ntawm kev ua tau zoo ntawm cov hlau txias -rolled steel?
A: Cov no feem ntau suav nrog lub zog tawm los, lub zog tensile, elongation, hardness, deg roughness, dimensional kam rau ua, thiab phaj zoo.
Qhov zoo ntawm qhov chaw txias - dov steel xeem li cas?
A: Los ntawm kev tshuaj xyuas qhov muag (rau qhov tsis xws luag xws li khawb thiab pitting), roughness meter (rau ntsuas qhov roughness), thiab kuaj ultrasonic (rau kev kuaj xyuas sab hauv).
Dab tsi yog qhov tshwm sim ntawm kev tawm dag zog ntau dhau rau txias -rolled steel?
A: Nws ua rau cov txheej txheem nyuaj (piv txwv li, tawg thaum lub sij hawm stamping) thiab txo cov formability. Nws yog qhov tsim nyog rau cov ntawv thov uas xav tau lub zog siab tab sis tsis yog rau cov txheej txheem sib sau ua ke.
Dab tsi yog qhov tseem ceeb ntawm elongation nyob rau hauv daim ntawv thov txias -rolled steel?
A: Elongation qhia txog cov yas ntawm cov hlau. Qhov siab dua qhov elongation, qhov tsim nyog nws yog rau cov txheej txheem nyuaj xws li stamping thiab dabtsi yog khoov. Nws feem ntau yog siv rau hauv cov ntawv thov xws li cov khoom siv tsheb thiab cov khoom siv hauv tsev.
Dab tsi yog txoj hauv kev uas feem ntau siv los ntsuas qhov hardness ntawm txias -rolled steel?
A: Brinell hardness (HB) thiab Rockwell hardness (HRB) feem ntau yog siv. Cov qauv xeem tsim nyog yuav tsum raug xaiv raws li cov khoom siv thiab cov tuab.
