2. Zeziphi iintlobo zeendlela zokugalela ezikhoyo ehlabathini?

IMPENDULO: Zintathu iindidi zeendlela zokugalela: ukugalela kombane, ukugalela okushushu kunye nokugalela igalvanizing.

3. Zeziphi iindidi ezimbini zokugalela idiphu eshushu ezinokohlulwa ngokweendlela ezahlukeneyo zokufunxa?

A: Inokwahlulwa ibe ziindidi ezimbini: i-in-line annealing kunye ne-off-line annealing, ezikwabizwa ngokuba yi-protect gas method kunye ne-flux method.

4. Ngawaphi amabakala entsimbi asetyenziswa ngokuqhelekileyo eshiti elishushu?

A: Uhlobo lwemveliso: I-coil ngokubanzi (CQ), i-galvanized sheet yesakhiwo (HSLA), umzobo onzulu otshisayo we-galvanized sheet (DDQ), ukubhaka ukuqina kwe-galvanized sheet (BH), intsimbi yesigaba sesibini (DP), intsimbi ye-TRIP (utshintsho lwesigaba lubangelwa intsimbi yeplastiki), njl.

5. Zeziphi iindlela zokutshisa iziko lomlilo?

Impendulo: Zintathu iindidi zesithando somlilo esithe nkqo, isithando somlilo esithe tye kunye nesithando somlilo esithe tye.

6, ngokuqhelekileyo kukho iindlela ezininzi zokupholisa zenqaba yokupholisa?

A: Kukho iindidi ezimbini: ukupholisa umoya kunye nokupholisa ngamanzi.

7. Zeziphi iziphene eziphambili zokugalela idiphu eshushu?

Impendulo: Ngokuyintloko: ukuwa, ukukrazula, indawo yokugqithisa, i-zinc grain, i-edge enzima, i-air knife striation, i-air knife scratch, intsimbi eveziweyo, ukubandakanywa, umonakalo womatshini, ukusebenza kakubi kwesiseko sentsimbi, umphetho wamaza, i-ladle curvature, ubukhulu, imprint, ubukhulu be-zinc layer, ukuprintwa komqulu, njl.

8. Eyaziwayo: ukucaciswa kwemveliso ngu-0.75 × 1050mm, kwaye ubunzima bekhoyili buziitoni ezi-5. Buthini ubude bomtya wekhoyili? (Ubunzima obuthile bephepha elenziwe igalvanized yi-7.85g/cm3)

Impendulo: Ubude be-coil strip yi-808.816m.

9. Ziziphi izizathu eziphambili zokuchithwa kwe-zinc layer?

Impendulo: Izizathu eziphambili zokuchithwa kwe-zinc layer zezi: I-surface oxidation, i-silicon compounds, i-emulsion ebophezelayo ebandayo ingcolile kakhulu, i-NOF oxidation atmosphere kunye ne-protect gas dew point iphezulu kakhulu, i-air fuel ratio ayinangqiqo, ukuhamba kwe-hydrogen kuphantsi, i-oxygen yesithando somlilo. ukungena, ubushushu bomcu ebhodweni buphantsi, icandelo le-RWP uxinzelelo lomlilo liphantsi kunye nokufakwa komoya emnyango, icandelo le-NOF. Iqondo lobushushu leziko liphantsi, ukuphuphuma kwe-oyile akwanelanga, umxholo we-aluminiyam we-zinc uphantsi, isantya seyunithi sikhawuleza kakhulu, ukucutha okungonelanga, ixesha lokuhlala lolwelo lwe-zinc lifutshane kakhulu, ukugquma okukhulu.

10. Yintoni ebangela umhlwa omhlophe namabala amnyama?

Impendulo: ibala elimnyama ngumhlwa omhlophe ukwakheka kwe-oxidation ngakumbi. Ezona zizathu ziphambili zomhlwa omhlophe zezi zilandelayo:I-passivation engalunganga, ukutyeba kwefilimu ye-passivation akwanelanga okanye ukungalingani; Umphezulu awufakwanga ngeoli okanye ukufuma okushiyekileyo kumphezulu womgca; Umphezulu we-strip uqulethe ukufuma xa udibanisa; I-passivation ayomiswanga ngokupheleleyo; Ubumanzi okanye imvula ngexesha lokuthutha okanye ukugcinwa; Ixesha lokugcinwa kwemveliso lide kakhulu; Ishiti elenziwe ngesinyithi kunye nezinye iasidi kunye nealkali kunye nolunye unxibelelwano oluphakathi elonakalisayo okanye lugcinwe kunye.
