Mukushandiswa kwakanyatsojeka kwakadai sekuvaka mahamvuropu, kugadzira midziyo yemumba, uye michina yechando, kugadzikana kwesimbi yegalvalume (inozivikanwawo secoil Gl) kunokanganisa zvakananga kurongeka kwekuisa uye goho remushonga wapera. Kunyangwe vatengi vari kusarudza zvigadzirwa zvegalvalume zvekutengesa kana vatengesi vesimbi yegalvalume vari kuvandudza kugadzirwa, zvakakosha kunzwisisa kuti kugadzikana kwesimbi hakusi netsaona, asi mhedzisiro yekudzora kwakarurama mukati memaitiro ese, kubva pakugadzirisa substrate uye kupisa-dip galvanizing kusvika pakutonhodza nekupedzisa. Semutengesi mukuru wepasi rose, makambani makuru esimbi yegalvalume muChina atove nemazinga anotungamira ekutonga kushivirira kwesimbi yesimbi yegalvalume kuburikidza nekuvandudza maitiro.
I. Zvinodiwa Zvikuru zveKugadzikana kweDimensional
Zvegalvalume yesimbi, kugadzikana kwehukuru kunonyanya kuratidzwa muzvikamu zvitatu, izvo zviriwo musiyano mukuru pakati pePrime galvalume steel coils nezvigadzirwa zvakajairika:
*Kutsauka kweChimiro cheSheet: Kutenderera ≤ 3mm/m muchimiro chakati sandara, pasina kukombama kana kukotama kuri pachena;
*Kushivirira Ukobvu: Kutsauka kwehukobvu hwechinhu chepasi ≤ ± 0.05mm, kutsauka kwehukobvu hwekuvhara ≤ 10%;
*Kugadzikana kweThermal: Mushure mekurapwa nekupisa kwakanyanya pa200℃ kwemaawa maviri, kushanduka kwechimiro ≤ 0.1%, zvichizadzisa zvinodiwa zve stamping, kukotama, uye mamwe magadzirirwo anotevera.
Zviratidzo izvi zvinosarudza zvakananga kuchinjika kwesimbi yegalvalume pakusanganisa, kuisa, uye kugadzira nemazvo, uye ndizvo zvinhu zvakakosha pakutenga zvigadzirwa zvegalvalume zvekutengesa.

II. Mhedzisiro yeMaitiro Mana Ekugadzira Zvinhu Zvikuru paKugadzikana Kwemativi
1. Kugadzirisa Substrate: "Chivimbiso Chekutanga" cheKugadzikana Kwemativi
Hunhu hwe substrate yegalvalume simbi coilZvinokanganisa zvakananga mashandiro ekupedzisira. Maitiro makuru anosanganisira kusvuura nekutwasanudza:
*Maitiro Ekunhonga: Kana nguva yekunhonga yakareba zvakanyanya kana kuti acid yakawanda zvakanyanya, zvinotungamira mukuora kwakanyanya kwe substrate, izvo zvinokonzeresa kudonha kusina kuenzana uye kutenderera panguva yekutonhorera kunotevera mushure mekuputira. Kusiyana neizvi, kunhonga kusina kukwana kuchasiya oxide scale, izvo zvinokonzeresa kusabatana zvakanaka kwe coating uye kukanganisa kusagadzikana kwe dimensional. Prime galvalume steel coils inowanzo shandisa "shallow pickling + online brushing", ichinyatsodzora acid concentration (18-22%) uye nguva yekurapa (30-40s) kudzivirira kukuvara kwe substrate.
*Maitiro Ekutwasanudza: Usati wapinda muhari ye galvanizing, substrate inofanira kutwasanudzwa ne multi-roller straightener kuti ubvise kumanikidzwa kwekutenderera. Kana mutsetse wekutwasanudza usina kugadziriswa zvakaenzana, zvichaita kuti pave nekusawirirana mukupararira kwekumanikidzwa kwemukati me substrate, zvichikonzera "kukotama kwe springback" panguva yekutonhorera mushure mekuputira. Vatengesi vepamusoro ve galvalume coil muChina vanoshandisa zvakanyanya michina yekutwasanudza yeCNC kuti vatarise kugadzikana kwe substrate munguva chaiyo, vachiona kuti kutsauka kwe flatness kwe ≤0.5mm/m mushure mekutwasanudza.
2. Maitiro Ekuvhara Mvura Inopisa: "Kuenzanisa Kwakakodzera" Kwekupisa Nekumhanya
Kuputira nekupisa ndiro danho guru pakuumba chifukidziro chesimbi galvalume. Maitiro ayo anokanganisa zvakananga kufanana kweukobvu hwechifukidziro uye kuchinja kwe substrate: Kudzora tembiricha yeZinc pot: Tembiricha yekupisa-kuputira yakajairwa i600-620℃. Kana kuchinja kwetembiricha kukadarika ±5℃, zvinotungamira kune kusawirirana kwekuita kwechifukidziro, zvichikonzera zvikanganiso zvakaita se "mipendero yakakora" uye "substrate yakaratidzwa," zvichikanganisa kushivirira kwese kweukobvu hwe coil. Kugadzirisa kumhanya kwestrip: Kumhanya kwestrip kunofanirwa kuenderana nekumhanya kwekunamatira kwe coating (kazhinji 10-15m/min). Kumhanya kwakanyanya kunogona kutungamira nyore nyore kune kuputira kwakatetepa uye kusina kufanana, nepo kumhanya kwakaderera kuchizokonzera kuputira kwakakora zvakanyanya uye kupisa kwe substrate. Mitsetse yekugadzira yePrime galvalume steel coils ine infrared temperature measurement uye speed closed-loop control systems kuti ive nechokwadi chekuti parameter stability.
3. Maitiro Ekutonhodza: ​​Danho Guru Mukudzivirira Kushanduka
Kutonhodza nekukurumidza mushure mekudziya-kudipudza kwakakosha kudzivirira kuchinja kwekupisa kwesimbi yegalvalume. Kana kutonhodza kwechisikigo kukashandiswa, musiyano uripo pakati pezvikamu zvekuwedzera kwekupisa pakati pe substrate ne coating (simbi: 11.5 × 10⁻⁶/℃, aruminiyamu-zinc alloy: 23 × 10⁻⁶/℃) zvichagadzira kushushikana kukuru kwekupisa, zvichikonzera kutenderera kwe coil uye waviness yakawandisa. Vatengesi ve galvalume coil vemhando yepamusoro vanoshandisa nzira yekutonhodza yakakamurwa: kutanga, kutonhodza kwemhepo kunoderedza tembiricha kusvika pa300℃, uye kutonhodza kwemvura kweatomized kunoderedza kusvika patembiricha yemukamuri, nekutonhora kuchidzorwa pa15-20℃/s, zvichideredza kushushikana kwekupisa. Vatengesi ve galvalume coil vepamusoro muChina vakaunzazve masisitimu ekutonhodza akangwara anogadzirisa kusimba kwekutonhodza munguva chaiyo zvichibva pakukora kwestrip kuti ive nechokwadi chekugadzikana kwemativi.
4. Maitiro Ekupedzisa: Kuenzanisa Kwakarurama Kwezvikamu Zvekupedzisira
Kupedzisa mushure mekuputira kunosarudza zvakananga kururama kwehukuru hwecoil galvalume. Maitiro makuru anosanganisira matanho maviri: kutwasanudza tension uye kuchekerera mucheto. Kutwasanudza tension: 1-2% tension rate inoshandiswa uchishandisa tension straightening machine kubvisa residual stress mukati me coil uye kugadzirisa small warping, zvichiita kuti sheet isvike padanho rakatsetseka. Kuchekerera mucheto: Muchina weCNC edge trimming unoshandiswa kudzora nemazvo coil width tolerance (deviation ≤ ±2mm), kudzivirira matambudziko pakuiswa uye kupwanyika nekuda kwekusaenzana kwemipendero. Maitiro ekupedzisa ePrime galvalume steel coils anosanganisirawo online dimensional test; zvigadzirwa zvisina kunaka zvinodzoserwa zvakananga kuti zvishandiswe patsva.
III. Kutenga neKusarudza: Ungaongorora sei Kugadzikana Kwezvikamu kuburikidza neMaitiro?
Kune makambani anotenga zvigadzirwa zvegalvalume zvekutengesa, zvinhu zvitatu zvinotevera zvinogona kushandiswa kuongorora zvigadzirwa zvemhando yepamusoro: Kumbira mishumo yemaitiro kubva kune vatengesi vegalvalume coil, vachitarisa zviratidzo zvakakosha zvakaita sekururama kwekutwasanudza substrate, huwandu hwekushanduka kwekushisa kwe zinc pot, uye nzira yekutonhodza; Isa pamberi maPrime galvalume steel coils, sezvo maitiro avo ekugadzira achishandisa kutonga kwakazara, kuve nechokwadi chekuti mativi acho anotenderwa zviri nani; Teerera kune zvinodiwa zvevatengesi vegalvalume coil china. Vatengesi vanotungamira vanowanzova nemidziyo yekuongorora chaiyo (senge laser thickness gauges uye shape measuring instruments) uye vanogona kupa mishumo yekuongorora yechitatu-bato.
Kugadzikana kwesimbi galvalume imhedzisiro ye "kudzora kwemazinga e millimeter" mukugadzirwa. Kubva pakugadzirisa substrate kusvika pakupedzisa nekutumira, kutsauka kwema parameter padanho rega rega kunogona kukanganisa mhando yekupedzisira. Kune vatengesi ve galvalume coil, kuvandudzwa kwemaitiro kwakakosha mukusimudzira kukwikwidzana kwechigadzirwa; kune vatengi, kunzwisisa hukama huripo pakati pemaitiro nekugadzikana kwezvikamu kwakakosha pakusarudza nemazvo galvalume steel coil inosangana nezvinodiwa zvavo. Mune ramangwana, nekuvandudzwa kwetekinoroji kweindasitiri ye galvalume coil muChina, kugadzikana kwezvikamu kuchava chinhu chakakosha chinosiyanisa zvigadzirwa zvemhando yepamusoro kubva kune zvigadzirwa zvakajairika, zvichitungamira kushandiswa kwesimbi galvalume mumamiriro ezvinhu akanyatsojeka.
