Raws li lub tsev tseem ceeb hauv kev lag luam niaj hnub, hlau kauj txheej txheem yuam kev ncaj qha cuam tshuam kev ua tau zoo, ua haujlwm, thiab qhov kawg thov cov txiaj ntsig. Steel kauj tsim yog ntau dua li cov ntaub ntawv yooj yim uas yooj yim; Theej, nws cuam tshuam nrog cov txheej txheem tsim nyog raws li cov ntaub ntawv txuj ci, ua haujlwm ua kom tau raws li cov txheej txheem sib txawv, thiab cov kev xav tau ntawm kev lag luam hauv ntau yam kev lag luam.
Los ntawm cov ntaub ntawv xaiv cov khoom siv rau cov khoom siv hlau rau cov hlau hlau feem ntau yog cov hlau sib txuas, cov hlau tshwj xeeb txiav txim siab lawv cov khoom siv hauv cov khoom siv. Piv txwv li, cov ntsiab lus carbon cuam tshuam tawv thiab lub zog, thaum ntxiv cov roj ntsha thiab npib tsib xee thiab txhim kho corrosion. Thaum lub sij hawm tsim theem, lub sijhawm alloy piv yuav tsum tau hloov kho raws li cov ntawv thov phiaj xwm kom ntseeg tau tias cov khoom muaj txiaj ntsig hauv cov xwm txheej tshwj xeeb. Piv txwv li, steel coils rau kev tsim kho tsheb yuav tsum tau ua kom muaj siab kom haum rau kev siv nyiaj, thaum hlau coils rau kev siv lub zog ua ntu zus thiab lub zog.
Nyob rau hauv cov nqe lus ntawm cov qauv tsim qauv, cov txheej txheem coil winding, thickness kam, thiab kev kho kom nto, yog qhov tseem ceeb yog qhov tseem ceeb. Kev tsim kho cov coilion tswj tau tuaj yeem tiv thaiv cov khoom siv deformation thiab kev ntxhov siab sab hauv, thaum cov tuab tuab tswj ncaj qha. Cov kev kho saum npoo xws li galvanizing, txheej, lossis polishing tsis tsuas yog txhim kho kom zoo nkauj tab sis kuj txhim kho kev kho mob corrosion thiab txuas ntxiv lub neej pabcuam. Tsis tas li ntawd, qhov dav thiab sab hauv ntawm hlau coil yuav tsum yog tsim los ua kom tau raws li cov qauv txheej txheem ntawm cov kab ntau lawm los txhim kho logistics thiab kev ua haujlwm.
Ua kom zoo ua kev tsim khoom tsim tau kuj tseem ceeb heev. Qhov kev xaiv nruab nrab ntawm kub - rolling thiab txias} {rolling nyob ntawm cov khoom siv thaum ub muaj zog tab sis muaj kev haum rau cov txheej txheem; Txias -} rolled coils muab cov khoom siv zoo nkauj thiab cov khoom siv hluav taws xob du rau cov khoom siv hauv tsev lossis cov cuab yeej siv. Tshaj tawm -}}}}}}}}}}}}}}}} ickling ntxiv kho cov khoom siv microstruction micrascing thiab tawv.
Lub science xwm ntawm steel kauj tsim yog ncaj qha rau cov kev ua tau zoo thiab cov khoom lag luam zoo ntawm kev lag luam hauv qab dej. Los ntawm cov khoom siv tshwj xeeb, kev txhim kho qauv qauv, thiab kev tsim kho cov hlua khi rau cov khoom siv hauv tsev, ua ib qho kev lag luam hauv ntiaj teb kev lag luam. Nyob rau yav tom ntej, tsav los ntawm txoj kev txhim kho thiab kev txhim kho steel, kev siv zog steel, muab kev txhawb nqa kom muaj zog rau kev lag luam tshiab.
