Ukutyhila i-Advantages ye-Hot-Dip Galvanizing kwi-Steel Industry

Intshayelelo:

I-Hot-dip galvanizing, eyaziwa ngokuba yi-galvanizing, yindlela esebenzayo yokukhusela izakhiwo zetsimbi ekudlekeni.Isetyenziswa kakhulu kumashishini ahlukeneyo, le nkqubo ibandakanya ukuntywiliselwa izinto zentsimbi ezisuswe ngumhlwa kwi-zinc etyhidiweyo kumaqondo obushushu aphezulu, okwenza umaleko we-zinc okhuselayo kumphezulu.Kule bhlog, siza kuphonononga inkqubo yokuvelisa i-galvanizing ye-hot-dip, ikhanyise kwiinzuzo zayo, kwaye ibonelele ngengqiqo kwiindlela ezahlukeneyo ezisetyenziswa kwishishini.

Inkqubo yeMveliso yokuDiphu eDiphu eshushu:

Inkqubo yemveliso yamaphepha ashushu-diphu anezibatha aquka amanqanaba amaninzi, kubandakanywa ukulungiswa kwepleyiti yoqobo, unyango lwangaphambi kokutyalwa, i-hot-dip plating, unyango lwe-post-plating, kunye nokuhlolwa kwemveliso egqityiweyo.Ngokuxhomekeke kwiimfuno ezithile, inkqubo ye-galvanizing ye-hot-dip ingahlelwa ngokweendlela ezimbini: ukudibanisa ngaphandle kwe-line kunye no-in-line annealing.

1. Ukufakelwa kwe-Off-line:

Kule ndlela, iipleyiti zetsimbi ziphinda zifakwe kwi-recrystallization kunye ne-annealing ngaphambi kokungena kumgca wokutshisa i-galvanizing line.Kubalulekile ukususa zonke iioksidi kunye nobumdaka ukusuka kumphezulu wentsimbi phambi kokuba i-galvanization.Oku kufezekiswa ngokukhethwa, kulandelwa ukusetyenziswa kwe-zinc chloride okanye i-ammonium chloride-zinc chloride solvent yokukhusela.I-Wet hot-dip galvanizing, sheet steel method, kunye ne-Wheeling hot-dip galvanizing yeminye imizekelo ewela phantsi kolu didi.

2. Ukudibanisa kumgca:

Kwi-in-line annealing, iikhoyili eziqengqelekayo ezibandayo okanye ezishushu zisetyenziswa ngokuthe ngqo njengepleyiti yoqobo yokugalela i-hot-dip.Ukukhuselwa kwerhasi i-recrystallization annealing yenzeke ngaphakathi kumgca we-galvanizing ngokwayo.Indlela ye-Sendzimir, indlela ye-Sendzimir elungisiweyo, indlela ye-Steel Union yase-US, indlela yeSilas, kunye nendlela ye-Sharon zezona ndlela zidumileyo ezisetyenziselwa ukufakwa kwe-in-line annealing.

Izinto eziluncedo kwiHot-Dip Galvanizing:

1. Iindleko eziphantsi zokuLungisa:

Inkqubo ye-galvanizing ye-hot-dip inika inzuzo yeendleko, ngokuyinhloko ngenxa yokusebenza kwayo kunye nekhono eliphezulu lomthamo.Ngexesha elifutshane lokucubungula xa kuthelekiswa nezinye iindlela zokukhusela i-corrosion, le nkqubo iqinisekisa ukuguqulwa ngokukhawuleza kunye nokugcinwa okubalulekileyo kwiindleko zabasebenzi kunye nezinto eziphathekayo.

2. IndeUkuqina:

Ingubo ye-zinc eyenziwe ngexesha lenkqubo ye-galvanization inika ukuqina okukhethekileyo, ukwandisa ixesha lokuphila kwamacandelo ensimbi.Iikhoyili zentsimbi ezishushu ezidiphu zinika amandla okumelana neemeko ezirhabaxa zokusingqongileyo, kubandakanywa ukubola, ukugruzuka kunye nefuthe.

3. Ukuthembeka Okulungileyo:

I-Hot-dip galvanizing ibonakalisa ukuthembeka okugqwesileyo ngenxa ye-homogeneous kunye nokungaguquguquki kokutyabeka okukunikayo.Oku kufana kuqinisekisa umaleko we-zinc kwindawo yonke, kungashiyi indawo yeendawo ezibuthathaka ezinokukhokelela kumhlwa.

4. Ukuqina okuqinileyo koMgqumo:

I-coating eveliswa nge-galvanizing eshushu-dip ibonisa ukuqina okugqwesileyo kunye nokuguquguquka.I-zinc layer ibotshelelwe ngokuqinileyo kwindawo yentsimbi, eyenza ukuba ixhathise kakhulu umonakalo womatshini ngexesha lokuthutha, ukufakwa kunye nenkonzo.

5. Ukhuseleko oluBanzi:

I-Hot-dip galvanizing inika ukhuseleko olubanzi kumacandelo entsimbi.I-zinc coating isebenza njengesithintelo somzimba ngokuchasene nokugqwala, ukukhusela intsimbi engaphantsi ekuvezweni kwizinto eziphazamisayo, ezifana nokufuma kunye neekhemikhali.

6. Ukugcina Ixesha kunye noMgudu:

Ngokubonelela ngokhuseleko lwe-corrosion oluhlala ixesha elide, i-coil-dip galvanized coil isusa isidingo sokugcinwa rhoqo kunye nokulungiswa.Oku kuguqulela kwixesha elibalulekileyo kunye nemizamo yokonga kumashishini axhomekeke kumalungu entsimbi egqunyiweyo.

Isiphelo:

I-Hot-dip galvanizing iye yaba yinxalenye yoshishino lwentsimbi ngaphezu kwenkulungwane.Ngokusebenza kwayo kweendleko, ukuqina, ukuthembeka, kunye nokhuseleko olubanzi, ibe yinto ekhethwayo yokuthintela ukubola.Nokuba kungokusebenzisa i-annealing ngaphandle kwe-line okanye ngo-in-line annealing, inkqubo ye-hot-dip galvanizing iqinisekisa amacandelo entsimbi ahlala ekwazi ukumelana nemiba yokusingqongileyo, ukwandisa ixesha lokuphila kwawo kunye nokunciphisa iindleko zokulondoloza.Njengoko imizi-mveliso iqhubeleka nokuvela, izibonelelo zokugalela intsimbi eshushu zenza ukuba ibe bubuchule obuyimfuneko kwintsimbi yokuchasa umhlwa.
