Chidziwitso cha Fakitale ya Galvanized Steel Coil pa coil yamalatisi

A-Kodi mitundu iwiri yakutentha-kuviika galvanizingmolingana ndi njira zosiyanasiyana zoyatsira?

Yankho: Ikhoza kugawidwa m'mitundu iwiri: in-line annealing ndi off-line annealing, yomwe imatchedwanso njira yotetezera gasi ndi njira yotuluka motsatira.

B-Magiredi achitsulo omwe amagwiritsidwa ntchito kwambiri ndi chiyaniotentha-kuviika malata mapepala?
Yankho: Magulu azinthu: koyilo yazinthu zonse (CQ), pepala lokhala ndi malata kuti agwiritse ntchito mwadongosolo (HSLA), pepala lozama kwambiri lovimbika (DDQ), pepala lowumitsa lotentha (BH), chitsulo chapawiri-gawo ( DP), TRIP chitsulo (kusintha kumapangitsa pulasitiki chitsulo), etc.

C- Ndi mitundu yanji ya ng'anjo zoyatsira malata zilipo?
Yankho: Pali mitundu itatu ya ng'anjo zoyimirira, ng'anjo zopindika zopingasa, ndi ng'anjo zoyatsira zoyima ndi zopingasa.

D-Kodi njira zoziziritsira za nsanja zozizirira ndi ziti?
A: Pali mitundu iwiri: kuziziritsa mpweya ndi kuziziritsa madzi.

E-Zolakwika zazikulu zakutentha-kuviika galvanizing?
Yankho: Makamaka zikuphatikizapo: kugwa, zokopa, passivation mawanga, zinc particles, wandiweyani m'mphepete, mpweya mpeni mikwingwirima, mpweya mpeni zokopa, poyera zitsulo, inclusions, kuwonongeka makina, kusagwira bwino zitsulo m'mphepete, mafunde m'mphepete, buckling, miyeso Mismatch, embossing , kusokonekera kwa makulidwe a zinc wosanjikiza, kusindikiza mpukutu, ndi zina.

F-Yodziwika: kapangidwe kake ndi 0,75 × 1050mm, ndi kulemera kwa koyilo ndi matani 5.Kodi kutalika kwa koyilo ndi kotani?(Kuchuluka kwa pepala lokhala ndi malata ndi 7.85g/cm3)

Yankho: L=G/(h×b×p)=(5×1000)/(0.785×1.050×7.5)=808.816m

Yankho: Koyiloyo ndi 808.816m kutalika.

G- Zifukwa zazikulu zopangira zinc layer ndi chiyani?
Yankho: Zifukwa zazikulu za peeling ya nthaka wosanjikiza ndi: pamwamba oxidation, silicon mankhwala, zauve kwambiri.ozizira adagulung'undisaemulsion, mpweya wochuluka kwambiri wa oxidizing ndi mpweya wotetezera mame mu gawo la NOF, chiŵerengero chopanda nzeru cha mpweya wamafuta, kutsika kwa hydrogen, ndi kulowetsa mpweya mu ng'anjo.Kutentha kwachotsa chitsulokulowa mumphika kumakhala kochepa, mphamvu ya ng'anjo mu gawo la RWP ndi yochepa ndipo chitseko cha ng'anjo cha ng'anjo, kutentha kwa ng'anjo mu gawo la NOF ndi chochepa, mafuta samatuluka, zitsulo za aluminiyumu za mphika wa zinc ndizochepa, liwiro la unit. imathamanga kwambiri, kuchepetsako sikukwanira, ndipo madzi a zinki Nthawi yokhalamo ndi yochepa kwambiri ndipo zokutira ndizovuta kwambiri.
