Ezinhlelweni zokusebenzisa ngokunemba njengemvilophu yokwakha, ukukhiqizwa kwemishini yasekhaya, kanye nemishini yochungechunge olubandayo, ukuzinza kobukhulu bekhoyili yensimbi ye-galvalume (eyaziwa nangokuthi i-coil Gl) kuthinta ngqo ukunemba kokufakwa kanye nomkhiqizo oqediwe. Kungakhathaliseki ukuthi abathengi bakhetha imikhiqizo yokuthengisa ye-galvalume noma abahlinzeki bekhoyili ye-galvalume benza ngcono ukukhiqizwa, kubalulekile ukuqonda ukuthi ukuzinza kobukhulu akuyona ingozi, kodwa kunalokho umphumela wokulawula okunembile kuyo yonke inqubo, kusukela ekunakekelweni kwe-substrate kanye ne-hot-dip galvanizing kuya ekupholiseni nasekuqedeni. Njengomhlinzeki omkhulu womhlaba wonke, izinkampani ezihamba phambili zekhoyili ye-galvalume eShayina sezivele zifinyelele amazinga ahamba phambili embonini okulawula ukubekezelelana kobukhulu bekhoyili yensimbi ye-galvalume eyinhloko ngokuthuthukiswa kwenqubo.
I. Imigomo Eyinhloko Yokuzinza Kobukhulu
Ngobai-galvalume yensimbi, ukuzinza kobukhulu kubonakala kakhulu ezilinganisweni ezintathu, okuphinde kube umehluko oyinhloko phakathi kwamakhoyili ensimbi e-Prime galvalume nemikhiqizo evamile:
*Ukuphambuka Komumo Weshidi: Ukugoba ≤ 3mm/m esimweni esiyisicaba, ngaphandle kokugoba okusobala noma ukugoba eceleni;
*Ukubekezelela Ubukhulu: Ukuphambuka kobukhulu bezinto eziyisisekelo ≤ ± 0.05mm, ukuphambuka kobukhulu bokumboza ≤ 10%;
*Ukuzinza Kokushisa: Ngemva kokwelashwa ngokushisa okuphezulu ku-200℃ amahora ama-2, ukuguqulwa kobukhulu ≤ 0.1%, okuhlangabezana nezidingo zokunyathela okulandelayo, ukugoba, nokunye ukucubungula.
Lezi zinkomba zinquma ngqo ukuthi ikhoyili yensimbi ye-galvalume iyakwazi ukuzivumelanisa nezimo ekuhlanganiseni, ekufakeni, nasekusebenzeni ngokunemba, futhi ziyizinto ezibalulekile okufanele uzicabangele lapho uthenga imikhiqizo yokuthengisa ye-galvalume.

II. Umthelela Wezinqubo Ezine Zokukhiqiza Eziyinhloko Ekuzinzeni Kobukhulu
1. Ukwelashwa Kwangaphambi Kwe-Substrate: "Isiqinisekiso Esiyisisekelo" Sokuzinza Kobukhulu
Ikhwalithi ye-substrate yeikhoyili yensimbi ye-galvalumekuthinta ngqo ukusebenza kobukhulu bokugcina. Izinqubo eziyinhloko zifaka phakathi ukukhahlela nokuqondisa:
*Inqubo Yokukha: Uma isikhathi sokukha siside kakhulu noma ukugcwala kwe-asidi kuphezulu kakhulu, kuzoholela ekugqwaleni okukhulu kobuso be-substrate, okuzobangela kalula ukushwabana kwendawo okungalingani kanye nokugoba ngesikhathi sokupholisa okulandelayo ngemva kokukha. Ngokuphambene nalokho, ukukhamba okungaphelele kuzoshiya isikali se-oxide, okuzobangela ukunamathela okubi kokumboza futhi kuthinte ngokungaqondile ukuzinza kobukhulu. Ama-coil ensimbi e-Prime galvalume ngokuvamile asebenzisa inqubo "yokukhamba okungajulile + ukuxubha online", elawula ngokunembile ukugcwala kwe-asidi (18-22%) kanye nesikhathi sokwelashwa (30-40s) ukugwema ukulimala kwe-substrate.
*Inqubo Yokuqondisa: Ngaphambi kokungena ebhodweni lokugaya, i-substrate idinga ukuqondiswa nge-multi-roller straightener ukuze kuqedwe ukucindezeleka kokugoqa. Uma igebe lokuqondisa lingalungiswanga ngokulinganayo, kuzoholela ekungalinganini ekusatshalalisweni kokucindezeleka kwangaphakathi kwe-substrate, okuholela "ekugobeni kwe-springback" ngesikhathi sokupholisa ngemuva kokufaka i-plating. Abahlinzeki bekhwalithi ephezulu be-galvalume coil eShayina basebenzisa kakhulu imishini yokuqondisa ye-CNC ukuqapha ukugoba kwe-substrate ngesikhathi sangempela, ukuqinisekisa ukuphambuka kokugoba okungu-≤0.5mm/m ngemva kokuqondisa.
2. Inqubo Yokumboza Ngokucwilisa Okushisayo: “Ibhalansi Eqondile” Yokushisa Nesivinini
I-hot-dip coating iyisinyathelo esiyinhloko ekwakheni i-coating ye-metal galvalume. Amapharamitha ayo enqubo athinta ngqo ukufana kobukhulu be-coating kanye nokuguqulwa kwe-substrate: Ukulawulwa kokushisa kwe-Zinc pot: Izinga lokushisa elijwayelekile le-hot-dip coating lingu-600-620℃. Uma ukuguquguquka kwezinga lokushisa kudlula ±5℃, kuzoholela ekusabeleni okungalingani kwe-alloying coating, okuholela ezifweni ezifana "nemiphetho ejiyile" kanye "ne-substrate eveziwe," ngaleyo ndlela kuthinte ukubekezelelana kobukhulu be-coil. Ukulungiswa kwesivinini se-strip: Isivinini sokusebenza kwe-strip kumele sihambisane nesivinini sokunamathela kwe-coating (ngokuvamile ngu-10-15m/min). Isivinini esiphezulu kakhulu singaholela kalula ekubambeni okuncane nokungalingani, kanti isivinini esiphansi kakhulu sizoholela ekubambeni okukhulu kakhulu kanye nokuguqulwa kwe-substrate ngokweqile. Imigqa yokukhiqiza yama-coil ensimbi e-Prime galvalume ifakwe ukulinganisa izinga lokushisa le-infrared kanye nezinhlelo zokulawula i-closed-loop speed ukuqinisekisa ukuzinza kwamapharamitha.
3. Inqubo Yokupholisa: Isinyathelo Esibalulekile Ekuvimbeleni Ukuguquka Kwesimo
Ukupholisa okusheshayo ngemva kokufaka i-galvanizing eshisayo kubalulekile ekuvimbeleni ukuguqulwa kokushisa kwe-coil yensimbi ye-galvalume. Uma kusetshenziswa ukupholisa kwemvelo, umehluko kuma-coefficients okukhulisa ukushisa phakathi kwe-substrate kanye ne-coating (insimbi: 11.5 × 10⁻⁶/℃, i-aluminium-zinc alloy: 23 × 10⁻⁶/℃) kuzodala ukucindezeleka okukhulu kokushisa, okuholela ekugobeni kwe-coil kanye nokugoba ngokweqile. Abahlinzeki be-coil ye-galvalume esezingeni eliphezulu basebenzisa inqubo yokupholisa ehlukanisiwe: okokuqala, ukupholisa umoya kwehlisa izinga lokushisa libe ngu-300℃, bese ukupholisa ngamanzi athomu kunciphisa izinga lokushisa legumbi, kanti izinga lokupholisa lilawulwa ku-15-20℃/s, kunciphisa ngempumelelo ukucindezeleka kokushisa. Abahlinzeki be-coil ye-galvalume abahamba phambili eShayina baqhubekile nokwethula izinhlelo zokupholisa ezihlakaniphile ezilungisa ukuqina kokupholisa ngesikhathi sangempela ngokusekelwe ekujikeni kwe-strip ukuqinisekisa ukuzinza kobukhulu.
4. Inqubo Yokuqeda: Ukulinganisa Okunembile Kobukhulu Bokugcina
Ukuqeda ngemuva kokufaka iplati kunquma ngqo ukunemba kobukhuluikhoyili ye-galvalume. Izinqubo eziyinhloko zifaka izinyathelo ezimbili: ukuqondisa ukucindezeleka kanye nokunciphisa unqenqema. Ukuqondisa Ukucindezeleka: Kusetshenziswa izinga lokucindezeleka elingu-1-2% kusetshenziswa umshini wokuqondisa ukucindezeleka ukuze kuqedwe ukucindezeleka okusele ngaphakathi kwekhoyili nokulungisa ukugoba okuncane, kuqinisekiswe ukuthi ishidi lifinyelela izinga eliyisicaba. Ukusika Unqenqema: Umshini wokusika unqenqema we-CNC usetshenziselwa ukulawula ngokunembile ukubekezelelana kobubanzi bekhoyili (ukuphambuka ≤ ±2mm), ukugwema ubunzima ekufakweni okulandelayo kanye nokuxhumanisa ngenxa yemiphetho engalingani. Inqubo yokuqeda amakhoyili ensimbi e-Prime galvalume ifaka nokuhlolwa kobukhulu obuku-inthanethi; imikhiqizo enephutha ibuyiselwa ngqo ukuze isetshenziswe kabusha.
III. Ukuthengwa Nokukhethwa: Ungahlulela Kanjani Ukuzinza Okulinganayo Ngenqubo?
Ezinkampanini ezithenga imikhiqizo yokuthengisa ye-galvalume, la maphuzu amathathu alandelayo angasetshenziswa ukuhlola imikhiqizo esezingeni eliphezulu: Cela imibiko yepharamitha yenqubo evela kubahlinzeki be-galvalume coil, ugxile ezinkombeni ezibalulekile njengokunemba kokuqondisa kwe-substrate, ububanzi bokuguquguquka kokushisa kwebhodwe le-zinc, kanye nendlela yokupholisa; Beka phambili ama-Prime galvalume steel coil, njengoba inqubo yawo yokukhiqiza isebenzisa ukulawula okuzenzakalelayo ngokuphelele, iqinisekisa ukubekezelelana okungcono kobukhulu; Naka izimfanelo zabahlinzeki be-galvalume coil china. Abahlinzeki abaphambili bavame ukuba nemishini yokuhlola ngokunemba (njengezilinganiso zobukhulu be-laser kanye nezinsimbi zokulinganisa ukuma) futhi banganikeza imibiko yokuhlola yobukhulu benkampani yangaphandle.
Ukuzinza kobukhulu be-galvalume yensimbi kuwumphumela "wokulawulwa kwezinga le-millimeter" enkambisweni yokukhiqiza. Kusukela ekuphathweni kwangaphambili kwe-substrate kuya ekuqedeni nasekuthunyelweni, ukuphambuka kwamapharamitha kuzo zonke izigaba kungathinta ikhwalithi yokugcina. Kubahlinzeki be-galvalume coil, ukuthuthukiswa kwenqubo kuyisihluthulelo sokuthuthukisa ukuncintisana komkhiqizo; kubathengi, ukuqonda ubudlelwano phakathi kwenqubo nokuzinza kobukhulu kubalulekile ekukhetheni ngokunembile i-galvalume steel coil ehlangabezana nezidingo zabo. Esikhathini esizayo, ngokuphindaphinda kobuchwepheshe kwemboni ye-galvalume coil yaseShayina, ukuzinza kobukhulu kuzoba ilebula eliyisihluthulelo elihlukanisa imikhiqizo esezingeni eliphezulu emikhiqizweni evamile, okuqhuba ukusetshenziswa kwe-galvalume yensimbi ezimweni ezinembile kakhulu.
