1. Cov yam ntxwv ntawm txias-dov automotive hlau
Cold-rolled automotive steelyog hais txog cov hlau uas yog tsim los ntawm kev ntxiv dov kub-dov hlau phaj los ntawm lub tshuab txias dov ntawm chav tsev kub. Nws muaj cov yam ntxwv ntawm lub zog siab, siab elongation, zoo heev qaug zog tsis kam, corrosion kuj thiab zoo formability, muab kev txhawb nqa txhim khu kev qha rau kev lag luam tsheb niaj hnub.
2. Cov txheej txheem ntau lawm
Cov txheej txheem tsim khoom ntawm cov tsheb txias-kuav los tiag steel feem ntau suav nrog kub dov, pickling, txias dov, annealing, xov thiab lwm yam. Thaum lub sij hawm kub dov txheej txheem, cov hlau molten yog cam khwb cia rau hauv ib lub steel billet los ntawm ib tug nruam casting tshuab, thiab ces rhuab nyob rau hauv lub cua sov rauv rau kub dov. Cov phaj kub-kuav los tiag steel phaj yog pickled kom tshem tawm nto oxide nplai, thiab ces nkag mus rau lub txias dov zeb rau dov. Rolled steel phaj yog annealed raws li xav tau los txhim kho nws cov khoom siv kho tshuab thiab kev ua haujlwm. Thaum kawg, tom qab ua tiav tiav, xws li txiav, ncab, tshuaj xyuas, thiab lwm yam, tau txais qhov txias txias-rolled automotive steel.
3. Daim ntawv thov teb
Cold-rolled automotive steel yog dav siv nyob rau hauv cov khoom tseem ceeb xws li tsheb lub cev, chassis, cav, thiab ncua kev kawm ntawv. Ntawm lawv, lub zog muaj zog txias-kuav los tiag tsheb hlau tau dhau los ua cov khoom tseem ceeb rau lub tsheb sib zog, txuag hluav taws xob thiab txo qis qis vim nws cov khoom siv zoo heev thiab kev qaug zog. Tsis tas li ntawd, nrog txoj kev loj hlob sai ntawm lub zog tshiab tsheb lag luam, txias-dov tsheb hlau nrog zoo corrosion kuj tau nce dav siv nyob rau hauv lub tshav pob ntawm lub zog tshiab.
