Hlau kauj, cov khoom siv yooj yim siv dav hauv kev lag luam niaj hnub no, muaj kev cuam tshuam ncaj qha rau qhov zoo thiab kev ntseeg siab ntawm cov khoom qis. Steel coil kev ua tau zoo yog feem ntau txiav txim siab los ntawm nws cov tshuaj muaj pes tsawg leeg, txheej txheem dov, thiab kev kho cua sov thev naus laus zis. Cov ntsuas tseem ceeb suav nrog cov khoom siv kho tshuab, qhov zoo ntawm qhov chaw, qhov tseeb qhov tseeb, thiab kev tiv thaiv corrosion.
Los ntawm kev xav, lub zog, ductility, thiab toughness yog cov yam ntxwv tseem ceeb ntawm steel coils. Los ntawm kev kho qhov sib piv ntawm alloying ntsiab xws li carbon, manganese, thiab silicon, ua ke nrog kev tswj dov thiab txias txheej txheem, lub zog yield thiab tensile lub zog ntawm steel coils tuaj yeem txhim kho tau zoo, ua tau raws li qhov yuav tsum tau ua ntawm siab -kawg daim ntawv thov xws li cov qauv hlau thiab cov ntawv hlau automotive. Piv txwv li, siab -lub zog qis- alloy steel coils, ua tiav los ntawm microalloying thev naus laus zis, ua tiav qhov hnyav txo thaum tuav lub zog thiab tau siv dav hauv engineering machinery thiab tsheb thauj mus los.
Nto zoo ncaj qha cuam tshuam rau kev ua haujlwm tom ntej ntawm cov hlau kauj thiab cov tsos ntawm cov khoom tiav. Niaj hnub rolling mills nruab nrog siab -cov txheej txheem yob qhov tseeb thiab kev tshuaj xyuas hauv online zoo tswj qhov tsis xws luag xws li nplai, khawb, thiab pitting. Tom qab annealing thiab flattening, txias- dov steel coils tuaj yeem ua tiav qhov roughness ntawm Ra Tsawg dua lossis sib npaug li 0.5μm, ua rau lawv tsim nyog rau cov khoom siv hauv tsev thiab cov khoom stamping precision. Dimensional raug thiab tswj cov duab yog cov txheej txheem tseem ceeb rau kev ntsuas qhov zoo ntawm steel coil manufacturing. Lub synergistic nyhuv ntawm txoj kab nruam annealing thiab ntau- yob zeb tso cai rau cov tuab tuab kom tswj tau li ntawm ± 0.05mm thiab qhov tsis sib xws yuav tsawg dua 3mm / m, ua kom ruaj khov thaum lub sij hawm tom ntej shearing thiab vuam txheej txheem.
Nyob rau hauv cov nqe lus ntawm corrosion kuj, galvanized thiab xim -coated steel coils undergone txheej txheej, ua kom lawv cov huab cua tsis kam nyob rau hauv ib puag ncig ntub thiab dhau los ua qhov kev xaiv rau lub tsev ntaub thaiv phab ntsa thiab vov tsev cov ntaub ntawv.
Hauv cov ntsiab lus, qhov ntau- qhov kev ua tau zoo ntawm cov hlau coils ua rau lawv yog ib qho khoom siv tseem ceeb hauv kev tsim khoom. Nrog rau yav tom ntej kev ua tiav nyob rau hauv qis - carbon metallurgical technologies, steel coils yuav muaj ntau dua daim ntawv thov kev cia siab nyob rau hauv ntsuab manufacturing.
