Pickling Kub Rolled Steel Chev
Qhov loj ntawm cov hlau phaj yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm lub rooj "Qhov ntev thiab cov lus qhia ntawm cov hlau kub dov (Tshooj los ntawm GB/T709-1988)".
Qhov loj ntawm cov hlau yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm lub rooj "Qhov ntev thiab cov lus qhia ntawm cov hlau kub dov (Tshooj los ntawm GB / T709-1988)".
Qhov dav ntawm lub phaj hlau kuj tseem tuaj yeem yog qhov loj me ntawm 50mm lossis ntau ntawm 10mm.
Qhov ntev ntawm cov hlau phaj yog txhua qhov loj me ntawm 100mm lossis ntau ntawm 50mm, tab sis qhov ntev tsawg kawg nkaus ntawm cov hlau phaj nrog qhov dav tsawg dua lossis sib npaug rau 4mm yuav tsum tsis pub tsawg dua 1.2m, thiab qhov ntev tsawg kawg nkaus ntawm cov hlau phaj nrog qhov tuab ntau dua 4mm yuav tsum tsis pub tsawg dua 2m.
Raws li qhov yuav tsum tau ua, qhov tuab ntawm cov hlau phaj tsawg dua 30 hli, qhov sib nrug tuab tuaj yeem yog 0.5 hli.
Raws li qhov xav tau, tom qab kev sib tham ntawm tus neeg muag khoom thiab tus neeg yuav khoom, cov hlau phaj thiab cov strips ntawm lwm qhov ntau thiab tsawg tuaj yeem muab tau.
Cov tuab sib xws:0.8, 1.0, 1.2, 1.5, 1.8, 2.0, 2.35, 2.45, 2.50, 2.70, 2.75, 2.8, 2.9, 2.95, 3.0, 3.25, 3.3, 3.5, 3.75, 3.8, 3.9, 3.95, 4, 4.25, 4.5, 4.7, 4.75, 5, 5.5, 5.75, 6, 6.75, 7, 7.5, 7.75, 8, 8.75, 9, 9.5, 9.75, 10, 10.5, 11, 11.5, 12
Raws li nws cov khoom siv thiab kev ua tau zoo, cov hlau kub txuas ntxiv tuaj yeem muab faib ua cov hlau carbon ib txwm muaj, cov hlau tsis tshua muaj hlau, thiab cov hlau sib xyaw. Raws li lawv cov kev siv sib txawv, lawv tuaj yeem muab faib ua: cov hlau ua kom txias, cov hlau ua qauv, cov hlau ua qauv tsheb, cov hlau ua qauv tiv taus xeb, cov hlau ua qauv kho tshuab, cov hlau roj welded thiab cov hlau siab, cov hlau kav dej, thiab lwm yam.
Lub phaj kub-dip galvanized kub-dov siv cov txheej txheem Sendzimir annealing zoo dua, thiab cov khoom siv raw yog cov kauj kub-dov pickled. Cov txheej txheem ntau lawm yog raws li nram no:
Cov kauj vuam kub dov → uncoiling → txiav taub hau thiab tus Tsov tus tw → vuam → nkag looper → hloov kho Sendzimir kab rov tav annealing cub tawg → kub-dip galvanizing → txias tom qab plating → zinc txheej thickness gauge → smoothing thiab straightening → passivation kho → Lub rooj tshuaj xyuas → Electrostatic oiling → Coiling → Weighing thiab packing → Cov khoom tiav cia.
