Dab tsi yog cov dej num thiab elongation tus nqi ntawm nto tiav (smoothing)?
A: Txhim kho daim ntawv zoo, tshem tawm cov qoob loo siab, thiab txhim kho qhov zoo; elongation 0.5-2.0% (0.5-1.0% hauv lub xeev mos).
Dab tsi yog cov txheej txheem thickness kam rau ua?
A: Ordinary precision ± 0.02mm, siab precision ± 0.01mm; dav kam rau ua ± 0.5mm, flatness Tsawg dua los yog sib npaug rau 3mm / m.
Dab tsi yog qhov tsis xws luag ntawm 1010 txias-rolled steel?
A: Kos, pitting, oxide nplai, tev, indentations, ntug waviness, camber, tapering, thiab roj residue.
Yuav ua li cas tiv thaiv nto khawb?
A: Siv daim iav- ua tiav cov yob, ua kom nruj nruj, tswj kev huv ntawm emulsion, ntxuav electrolytic (roj Tsawg dua lossis sib npaug li 5mg / m²), thiab tsis txhob muaj cov khoom txawv teb chaws indentation.
Dab tsi yog qhov ua rau thiab kev tiv thaiv ntawm oxide scale tsim?
A: Cov huab cua tsis zoo annealing, lub sij hawm ntev uncoiling raug; tswj cov nitrogen-hydrogen tiv thaiv huab cua, txo lub sij hawm raug, thiab siv cov roj los tiv thaiv- xeb.
