Hauv cov ntawv thov precision xws li lub hnab ntawv tsim kho, kev tsim khoom siv hauv tsev, thiab cov khoom siv saw hlau txias, qhov ruaj khov ntawm galvalume steel kauj (tseem hu ua coil Gl) cuam tshuam ncaj qha rau qhov tseeb ntawm kev teeb tsa thiab cov khoom tiav. Txawm hais tias cov neeg yuav khoom xaiv cov khoom muag galvalume lossis cov neeg muag khoom galvalume coil tab tom ua kom zoo dua qub, nws yog qhov tseem ceeb kom nkag siab tias qhov ruaj khov ntawm qhov ntev tsis yog qhov xwm txheej, tab sis yog qhov tshwm sim ntawm kev tswj hwm meej thoob plaws hauv tag nrho cov txheej txheem, los ntawm kev kho cov khoom siv thiab kev kub-dip galvanizing mus rau kev txias thiab kev ua tiav. Raws li tus neeg muag khoom loj thoob ntiaj teb, cov tuam txhab galvalume coil hauv Suav teb twb tau ua tiav cov qib kev lag luam ntawm kev tswj hwm qhov ntev rau cov hlau galvalume hlau los ntawm kev txhim kho cov txheej txheem.
I. Cov Qauv Tseem Ceeb rau Kev Ruaj Ntseg ntawm Qhov Ntev
Rauhlau galvalume, qhov ruaj khov ntawm qhov ntev feem ntau yog pom tseeb hauv peb qhov ntev, uas kuj yog qhov sib txawv tseem ceeb ntawm Prime galvalume steel coils thiab cov khoom lag luam ib txwm muaj:
* Kev Hloov Pauv ntawm Daim Ntawv: Qhov Wavyness ≤ 3mm/m hauv lub xeev tiaj tus, tsis muaj qhov pom tseeb ntawm kev khoov lossis kev khoov sab nraud;
* Kev kam rau tuab: Qhov sib txawv ntawm cov khoom siv hauv paus tuab ≤ ± 0.05 hli, qhov sib txawv ntawm cov txheej tuab sib xws ≤ 10%;
* Kev Ruaj Ntseg Thermal: Tom qab kev kho mob kub siab ntawm 200 ℃ rau 2 teev, qhov kev hloov pauv ntawm qhov ntev ≤ 0.1%, ua tau raws li qhov yuav tsum tau ua ntawm kev ntaus cim, khoov, thiab lwm yam kev ua tiav tom qab.
Cov ntsuas no ncaj qha txiav txim siab qhov kev hloov pauv ntawm galvalume steel kauj hauv kev sib txuas, kev teeb tsa, thiab kev ua haujlwm raug, thiab yog qhov tseem ceeb uas yuav tsum xav txog thaum yuav cov khoom muag galvalume.

II. Kev cuam tshuam ntawm Plaub Txoj Kev Tsim Khoom Tseem Ceeb rau Kev Ruaj Ntseg ntawm Qhov Ntev
1. Kev Kho Ua Ntej Rau Cov Khoom Siv: "Kev Lav Paub Yooj Yim" ntawm Kev Ruaj Ntseg Ntawm Qhov Ntev
Qhov zoo ntawm lub substrate raugalvalume hlau kaujncaj qha cuam tshuam rau qhov kev ua tau zoo kawg nkaus. Cov txheej txheem tseem ceeb suav nrog kev pickling thiab straightening:
* Cov Txheej Txheem Pickling: Yog tias lub sijhawm pickling ntev dhau los yog cov kua qaub ntau dhau, nws yuav ua rau muaj kev xeb ntau dhau ntawm qhov chaw substrate, uas yuav yooj yim ua rau tsis sib xws hauv zos shrinkage thiab warping thaum lub sijhawm txias tom qab plating. Ntawm qhov tod tes, pickling tsis tiav yuav tawm hauv oxide nplai, uas yuav ua rau cov txheej txheem tsis zoo thiab cuam tshuam tsis ncaj qha rau qhov ruaj khov ntawm qhov ntev. Prime galvalume steel coils feem ntau siv cov txheej txheem "shallow pickling + online brushing", tswj hwm qhov acid concentration (18-22%) thiab lub sijhawm kho (30-40s) kom tsis txhob muaj kev puas tsuaj rau substrate.
*Txheej Txheem Ncaj: Ua ntej nkag mus rau hauv lub lauj kaub galvanizing, lub substrate yuav tsum tau ncaj los ntawm ntau lub roller straightener kom tshem tawm kev ntxhov siab dov. Yog tias qhov sib txawv ntawm kev ncaj yob tsis raug kho kom sib npaug, nws yuav ua rau muaj kev tsis sib npaug ntawm kev faib tawm kev ntxhov siab sab hauv ntawm lub substrate, ua rau "springback bending" thaum lub sijhawm tom qab plating txias. Cov neeg muab khoom zoo ntawm galvalume coil hauv Suav teb feem ntau siv CNC straightening cov khoom siv los saib xyuas qhov tiaj tus ntawm lub substrate hauv lub sijhawm tiag tiag, kom ntseeg tau tias qhov tiaj tus ntawm ≤0.5mm / m tom qab ncaj.
2. Cov Txheej Txheem Txheej Txheem Kub-dip: "Qhov Sib Npaug Tseeb" ntawm Kub thiab Ceev
Kev txheej kub-dip yog cov kauj ruam tseem ceeb hauv kev tsim cov txheej rau hlau galvalume. Nws cov txheej txheem tsis ncaj qha cuam tshuam rau qhov sib xws ntawm cov tuab txheej thiab kev hloov pauv ntawm cov khoom siv: Kev tswj qhov kub ntawm lub lauj kaub zinc: Qhov kub txheej kub-dip txheem yog 600-620 ℃. Yog tias qhov kub hloov pauv ntau tshaj ± 5 ℃, nws yuav ua rau muaj kev sib xyaw tsis sib xws ntawm cov txheej, ua rau muaj qhov tsis zoo xws li "ntug tuab" thiab "cov khoom siv raug," yog li cuam tshuam rau qhov tuab tag nrho ntawm lub kauj. Kev hloov kho qhov ceev ntawm daim kab xev: Qhov ceev khiav ntawm daim kab xev yuav tsum phim qhov ceev ntawm kev nplaum txheej (feem ntau 10-15m / feeb). Qhov ceev siab dhau tuaj yeem ua rau cov txheej nyias thiab tsis sib xws, thaum qhov ceev qis dhau yuav ua rau cov txheej tuab dhau thiab kev hloov pauv ntawm cov khoom siv. Cov kab ntau lawm ntawm cov hlau galvalume tau nruab nrog kev ntsuas kub infrared thiab kev tswj hwm ceev kaw-lub voj voog kom ntseeg tau tias qhov ruaj khov ntawm cov txheej txheem.
3. Txheej Txheem Txias: Ib Kauj Ruam Tseem Ceeb hauv Kev Tiv Thaiv Kev Hloov Pauv
Kev txias sai tom qab kub-dip galvanizing yog qhov tseem ceeb rau kev tiv thaiv kev hloov pauv thermal ntawm galvalume steel kauj. Yog tias siv txias ntuj, qhov sib txawv ntawm cov coefficients thermal expansion ntawm lub substrate thiab txheej (hlau: 11.5 × 10⁻⁶/℃, txhuas-zinc alloy: 23 × 10⁻⁶/℃) yuav tsim kev ntxhov siab thermal loj heev, ua rau coil warping thiab ntau dhau waviness. Cov neeg muag khoom galvalume coil zoo siv cov txheej txheem txias segmented: thawj zaug, cua txias txo qhov kub kom txog 300 ℃, tom qab ntawd atomized dej txias txo nws mus rau chav tsev kub, nrog rau qhov txias tswj ntawm 15-20 ℃ / s, zoo txo ​​qhov kev ntxhov siab thermal. Cov neeg muag khoom galvalume coil ua lag luam hauv Suav teb tau qhia ntxiv txog cov txheej txheem txias ntse uas kho qhov txias zog hauv lub sijhawm tiag tiag raws li qhov tuab ntawm daim kab xev kom ntseeg tau tias muaj kev ruaj khov ntawm qhov ntev.
4. Txheej Txheem Ua Kom Tiav: Kev Ntsuas Qhov Ntev Kawg
Kev ua tiav tom qab plating ncaj qha txiav txim siab qhov tseeb ntawm qhov ntev ntawmkauj galvalume. Cov txheej txheem tseem ceeb suav nrog ob kauj ruam: kev ncaj ncaj thiab kev txiav ntug. Kev Ncaj Ncaj: Siv 1-2% qhov nrawm nrawm siv lub tshuab ncaj ncaj kom tshem tawm kev ntxhov siab seem hauv lub kauj thiab kho qhov me me warping, xyuas kom meej tias daim ntawv mus txog tus qauv tiaj tus. Kev Txiav Ntug: Lub tshuab txiav ntug CNC siv los tswj qhov dav ntawm lub kauj (kev sib txawv ≤ ± 2 hli), zam kev nyuaj hauv kev teeb tsa tom qab thiab kev sib txuas vim yog cov npoo tsis sib xws. Cov txheej txheem tiav rau Prime galvalume steel coils kuj suav nrog kev tshuaj xyuas qhov ntev online; cov khoom tsis zoo raug xa rov qab ncaj qha rau kev ua haujlwm dua.
III. Kev Yuav Khoom thiab Kev Xaiv: Yuav Ua Li Cas Txiav Txim Siab Qhov Ruaj Khoov Los Ntawm Cov Txheej Txheem?
Rau cov tuam txhab uas yuav cov khoom galvalume muag, peb lub ntsiab lus hauv qab no tuaj yeem siv los tshuaj xyuas cov khoom zoo: Thov cov ntaub ntawv qhia txog cov txheej txheem los ntawm cov neeg muag khoom galvalume coil, tsom mus rau cov cim tseem ceeb xws li qhov tseeb ntawm cov substrate straightening, zinc pot kub hloov pauv ntau yam, thiab txoj kev txias; Muab qhov tseem ceeb rau Prime galvalume steel coils, vim tias lawv cov txheej txheem tsim khoom siv kev tswj hwm tag nrho, kom ntseeg tau tias muaj kev kam rau siab zoo dua; Ua tib zoo saib xyuas cov kev tsim nyog ntawm cov neeg muag khoom galvalume coil Tuam Tshoj. Cov neeg muag khoom ua thawj coj feem ntau muaj cov khoom siv kuaj xyuas qhov tseeb (xws li laser thickness gauges thiab cov cuab yeej ntsuas duab) thiab tuaj yeem muab cov ntaub ntawv tshuaj xyuas qhov ntev ntawm cov neeg thib peb.
Qhov ruaj khov ntawm cov hlau galvalume yog qhov tshwm sim ntawm "kev tswj hwm theem millimeter" hauv cov txheej txheem ntau lawm. Txij li kev kho ua ntej rau kev ua tiav thiab kev xa khoom, qhov kev hloov pauv ntawm txhua theem tuaj yeem cuam tshuam rau qhov zoo kawg. Rau cov neeg muab khoom galvalume coil, kev txhim kho cov txheej txheem yog qhov tseem ceeb rau kev txhim kho kev sib tw ntawm cov khoom; rau cov neeg yuav khoom, kev nkag siab txog kev sib raug zoo ntawm cov txheej txheem thiab kev ruaj khov ntawm qhov ntev yog qhov tseem ceeb rau kev xaiv cov hlau galvalume uas ua tau raws li lawv cov kev xav tau. Yav tom ntej, nrog rau kev siv tshuab ntawm kev lag luam galvalume coil Tuam Tshoj, kev ruaj khov ntawm qhov ntev yuav dhau los ua lub npe tseem ceeb uas cais cov khoom zoo los ntawm cov khoom ib txwm muaj, tsav tsheb siv cov hlau galvalume hauv cov xwm txheej meej dua.
