Cov kev cai rau txias- dov steel strip feem ntau suav nrog cov hauv qab no:
① Surface Condition and Surface Roughness. Txias-rolled steel strip nta zoo heev processability thiab aesthetically pleasing nto tiav; nws nquag siv rau cov vaj huam sib luag pom thiab sib sib zog nqus- daim ntawv thov kos duab, thiab yog li, qhov tsis xws luag yuav tsum tau zam nruj me ntsis.
② Dimensional thiab Shape Accuracy. Qhov tseeb qhov tseeb ntawm qhov txias txias -rolled steel strip npog precision hauv thickness, dav, thiab ntev, nrog kev tso cai sib txawv tau teev tseg hauv cov qauv tsim nyog. Cov duab raug yog feem ntau yog tus yam ntxwv ntawm flatness, lateral camber, thiab squareness, cov kev txwv pub rau uas kuj tau txhais nyob rau hauv cov qauv no.
③ Kev ua tau zoo. Txias- cov khoom dov ua haujlwm rau ntau lub hom phiaj thiab dhau los ua ntau txoj hauv kev-xws li los ntawm kev khoov yooj yim mus rau qhov tob tob. Hais txog kev ua tau zoo, lawv tuaj yeem muab faib ua ob hom: formability (encompassing extensibility thiab tob-drawability) thiab cov duab tuav. Formability yog hais txog cov khoom muaj peev xwm ua tiav rau hauv cov duab tshwj xeeb. Cov duab tuav yog hais txog qhov ntev thiab geometry ntawm cov khoom tom qab kev ua haujlwm tau raug tshem tawm; Cov yam ntxwv tseem ceeb ntawm kev tswj cov txheej txheem no yog hu ua "shape stability."
④ Kev laus yam ntxwv. Qhov tshwm sim ntawm "kev laus" yog hais txog cov kev hloov pauv uas tshwm sim hauv cov hlau lossis hlau dhau lub sijhawm dhau los. Txias- cov ntawv yob cov ntawv hlau yog raug rau ob qho tib si quench aging thiab strain aging. Quench aging tshwm sim thaum cov khoom yog txias txias los ntawm qhov kub thiab txias; strain aging, conversely, tshwm sim thaum lub sij hawm tom ntej txias ua hauj lwm (xws li temper dov) tom qab annealing - notably, lub yield point elongation (los yog "yield plateau") uas tau tshem tawm thaum npau taws dov yuav rov tshwm sim tom qab ib lub sij hawm.
⑤ Cov Khoom Tshwj Xeeb. Cov qeb no feem ntau suav nrog cov yam ntxwv tshwj xeeb xws li enamelability, corrosion resistance, electromagnetic zog, thiab blanking kev ua tau zoo.
