Emkhakheni wokukhiqiza insimbi, iJindalai Steel Group Co., Ltd. ivelele njengomhlinzeki ohamba phambili wama-coil e-galvanized, ikakhulukazi ama-coil ensimbi e-galvanized e-hot-dip. Phakathi kobuchwepheshe obuhlukahlukene bokulwa nokugqwala obutholakalayo, i-hot-dip galvanizing ivele njengompetha ongenakuphikiswa, ihlinzeka ngamashumi eminyaka yokuvikelwa okuthembekile ngezindleko eziphansi kakhulu. Kodwa yini eyenza le nqubo isebenze kahle kangaka, futhi izinyathelo ezihilelekile ekukhiqizweni kwama-coil e-galvanized zinikela kanjani ekhwalithini yomkhiqizo wokugcina?
Ukukhiqizwa kwama-coil e-galvanized kuhilela izinyathelo eziningana ezibalulekile: ukukhulula, ukuhlanza, ukuhlanganisa, ukuhlanganisa i-hot-dip galvanizing, ukupholisa, ukufaka i-passivation/oil, kanye nokubuyisela emuva. Isigaba ngasinye sidlala indima ebalulekile ekunqumeni ikhwalithi yokugcina ye-coil yensimbi e-galvanized. Isibonelo, ngesikhathi senqubo yokuhlanganisa, insimbi kumele iphathwe ngokucophelela ukuze kuvinjelwe noma yikuphi ukuguquka. Ukuhlanza kubalulekile ukususa noma yikuphi ukungcola okungathinta ukunamathela kwengqimba ye-zinc. Inqubo yokuhlanganisa iqinisekisa ukuthi insimbi isesimweni esifanele sokwamukela i-zinc coating, kuyilapho ukufaka i-hot-dip galvanizing kulapho kwenzeka khona umlingo—ukucwilisa insimbi ku-zinc encibilikisiwe kudala isithiyo esinamandla ngokumelene nokugqwala. Ukupholisa, ukufaka i-passivation, kanye nokufaka i-oil kuthuthukisa kakhulu ukuqina nokusebenza kwe-coil. Lezi zinyathelo ezicophelelayo ziqinisekisa kanjani ukuthi umkhiqizo wokugcina uhlangabezana nezindinganiso eziphakeme ezilindelwe embonini?
Njengoba imakethe ithuthuka, kukhona ushintsho oluphawulekayo oluya emikhiqizweni ehlanganisiwe "engenazo iziphandla", ene-splengle encane noma i-gloss. Lo mkhuba uvelele kakhulu embonini yokumboza ephezulu, lapho ubuhle nokusebenza kubaluleke kakhulu. Imikhiqizo engenazo iziphandla inikeza isiphetho esibushelelezi esivame ukuthandwa yizinhlelo zokusebenza ezidinga ukubukeka okuhle. Ngaphezu kwalokho, inikeza ukunamathela okungcono kopende futhi ayithambekeli kakhulu ezifweni zomphezulu. Kungani abakhiqizi nabathengi bethanda lezi zindlela zesimanje, futhi ziqhathaniswa kanjani nemikhiqizo yendabuko "enkulu yeziphandla" maqondana nokusebenza kahle kanye nokusebenza kahle kwezindleko?
Uma kukhulunywa ngokucubungula ama-coil e-galvanized, izici ngesikhathi sokusika, ukunyathela, kanye nokushisela zibalulekile. Isendlalelo se-zinc sinikeza isivikelo esihle kakhulu ekugqwaleni, kodwa singaletha nezinselele ngesikhathi sokwenziwa. Ukuqhekeka nokuqhekeka kwesendlalelo se-zinc kungenzeka uma insimbi ingalungiswanga kahle noma uma imingcele yokushisela ingalungiswanga kahle. Ukuvimbela lezi zinkinga, kubalulekile ukugcina ubuqotho be-zinc coating kuyo yonke inqubo yokukhiqiza. Yimiphi imikhuba engcono kakhulu engasetshenziswa ukuqinisekisa ukuthi ama-coil e-galvanized agcina izakhiwo zawo zokuvikela ngesikhathi sokusika nokushisela? Ngaphezu kwalokho, ukubhekana nezinkinga zempilo kanye nenqubo ezibangelwa umhwamuko we-zinc ngesikhathi sokushisela kubalulekile. Umoya owanele kanye nemishini yokuvikela kuyadingeka ukuvikela abasebenzi ngenkathi kugcinwa ukugeleza kokukhiqiza okubushelelezi.
Ekuphetheni, inqubo yokugaya ngogesi esetshenziswa yiJindalai Steel Group Co., Ltd. ayiqinisekisi nje kuphela ukuthi amakhoyili e-galvanised ahlala isikhathi eside futhi athembekile kodwa futhi iwabeka njengesixazululo esingabizi kakhulu embonini yensimbi. Njengoba imikhiqizo engenazo iziphanyeko ithandwa kakhulu kanye nesidingo sokunaka ngokucophelela imininingwane ngesikhathi sokucubungula, kusobala ukuthi ikusasa lensimbi e-galvanised liqhakazile. Njengomhlinzeki ohamba phambili wekhoyili e-galvanised, iJindalai Steel Group izibophezele ekuletheni imikhiqizo esezingeni eliphezulu ehlangabezana nezidingo ezishintshayo zemakethe. Iphrojekthi yakho elandelayo izozuza kanjani ngekhwalithi kanye nokusebenza okungenakuqhathaniswa kwamakhoyili e-galvanised a-galvanised a-hot-dip?
