Dab tsi yog txias -rolled steel ntawv?
Txias-rolled steel ntawv yog ib daim ntawv hlau uas ua los ntawm dov kub-rolled steel ntawv nyob rau hauv chav tsev kub uas siv lub txias dov zeb. Nws lub thickness yog feem ntau ntawm 0.1-3.0 hli, thiab nws muaj ib tug du nto thiab siab precision.
Dab tsi yog qhov txawv ntawm qhov txias- dov thiab kub- dov steel ntawv?
Qhov sib txawv ntawm qhov sib txawv ntawm qhov kub dov (txias dov ntawm chav tsev kub, kub dov ntawm qhov kub siab), qhov zoo ntawm qhov chaw (txias dov yog du thiab tsis muaj oxide nplai, kub dov muaj oxide nplai), qhov tseeb qhov tseeb (txias dov muaj qhov tseeb dua), thiab cov khoom siv kho tshuab (txias dov muaj zog dua thiab tawv, tab sis me ntsis qis dua rau lub zog thiab hardness).
Dab tsi yog cov ntaub ntawv tseem ceeb uas siv hauv cov ntawv txias -rolled steel?
Cov khoom siv feem ntau suav nrog cov pa roj carbon zoo tib yam (xws li SPCC, DC01), siab- cov pa roj carbon zoo (xws li 08Al), qis- alloy steel (xws li Q235 txias- qib dov), thiab stainless hlau (xws li 304, 316 txias- cov ntawv dov).
Dab tsi yog lub hom phiaj ntawm cov txheej txheem "annealing" hauv cov ntawv txias -rolled steel? Annealing yog txheej txheem tseem ceeb tom qab txias dov, txhawm rau tshem tawm cov kev ntxhov siab, txo qhov nyuaj, rov ua kom tawv tawv, thiab txhim kho kev ua haujlwm ntawm cov ntawv hlau (xws li stamping thiab dabtsi yog khoov), uas ua rau muaj kev sib txuam ntau dua.
Dab tsi yog cov qauv siv rau cov ntawv txias- dov steel? Feem ntau siv cov qauv hauv tsev: GB / T 708 (Dimensions, puab, hnyav thiab tso cai sib txawv ntawm txias- dov steel los xij thiab strips), GB / T 11253 (Txias- dov nyias carbon structural steel nplooj ntawv thiab strips); Cov qauv thoob ntiaj teb: JIS G 3141 (Nyiv), EN 10130 (EU), ASTM A1008 (USA).
