Dab tsi yog txias -rolled steel ntawv?
Txias-rolled steel ntawv yog steel ntawv dov nyob rau hauv chav tsev kub piv rau kub- dov steel ntawv, ua rau ib tug smoother nto thiab ntau dua qhov tseeb.
Dab tsi yog qhov txawv ntawm qhov txias- dov thiab kub- dov steel ntawv?
Qhov kub dov txawv (txias dov ntawm chav tsev kub, kub dov ntawm qhov kub siab). Txias- cov nplooj ntawv steel dov muaj qhov smoother thiab qhov tseeb dua qhov ntev, thaum kub- cov ntawv dov steel muaj qhov toughness zoo dua thiab tus nqi qis dua.
Dab tsi yog cov ntaub ntawv tseem ceeb uas siv hauv cov ntawv txias -rolled steel?
Cov ntaub ntawv muaj xws li SPCC (cov pa roj carbon zoo ib yam), DC01-DC06 (txias-cov pa roj carbon tsawg), Q235 (cov hlau tsis tshua muaj hlau), thiab 304/316 (stainless hlau).
"annealing" txhais li cas nyob rau hauv cov ntsiab lus ntawm txias-rolled steel ntawv?
Nws yog txheej txheem cua sov thiab tom qab ntawd txias tom qab dov kom tshem tawm cov kev ntxhov siab sab hauv thiab txhim kho plasticity thiab toughness.
Dab tsi yog cov qauv siv rau cov ntawv txias- dov steel?
Cov qauv hauv tsev suav nrog GB / T 708, thiab cov qauv thoob ntiaj teb suav nrog JIS G 3141 thiab ASTM A1008.
