Cov Txheej Txheem Kos Duab ntawm Galvanized Steel Wire
lGalvanizing ua ntej kos duab:txhawm rau txhim kho kev ua tau zoo ntawm cov hlau galvanized, cov txheej txheem ntawm kev kos cov hlau hlau rau cov khoom tiav tom qab ua kom cov hlau txhuas annealing thiab galvanizing hu ua plating ua ntej kos cov txheej txheem. Cov txheej txheem ntws ib txwm yog: hlau hlau - txhuas quenching - galvanizing - kos duab - hlau hlau tiav. Cov txheej txheem ntawm thawj plating thiab tom qab ntawd kos duab yog cov txheej txheem luv tshaj plaws hauv txoj kev kos duab ntawm cov hlau galvanized, uas tuaj yeem siv rau kub galvanizing lossis electrogalvanizing thiab tom qab ntawd kos duab. Cov khoom siv kho tshuab ntawm kub dip galvanized hlau hlau tom qab kos duab zoo dua li ntawm cov hlau hlau tom qab kos duab. Ob leeg tuaj yeem tau txais cov txheej zinc nyias thiab sib xws, txo cov zinc noj thiab ua kom lub nra hnyav ntawm kab galvanizing.
lCov txheej txheem kos duab tom qab galvanizing theem nrab:Cov txheej txheem kos duab tom qab galvanizing nruab nrab yog: hlau hlau - txhuas quenching - thawj daim duab - galvanizing - thib ob daim duab - tiav hlau hlau. Qhov tshwj xeeb ntawm nruab nrab plating tom qab kos duab yog tias cov hlau hlau txhuas quenched yog galvanized tom qab ib daim duab thiab tom qab ntawd yog kos rau cov khoom tiav ob zaug. Lub galvanizing yog nyob nruab nrab ntawm ob daim duab, yog li nws hu ua nruab nrab plating,. Cov txheej zinc ntawm hlau hlau tsim los ntawm nruab nrab plating thiab tom qab ntawd kos duab yog tuab dua li qhov tsim los ntawm plating thiab tom qab ntawd kos duab. Tag nrho compressibility (los ntawm txhuas quenching mus rau cov khoom tiav) ntawm kub dip galvanized hlau hlau tom qab plating thiab kos duab yog siab dua li ntawm hlau hlau tom qab plating thiab kos duab.
lCov txheej txheem sib xyaw galvanizing:Yuav kom tsim tau cov hlau galvanized uas muaj zog heev (3000 N/mm2), yuav tsum siv cov txheej txheem "sib xyaw galvanizing thiab kos duab". Cov txheej txheem ib txwm muaj yog raws li nram no: kev tua cov hlau txhuas - kev kos duab thawj zaug - kev galvanizing ua ntej - kev kos duab thib ob - kev galvanizing zaum kawg - kev kos duab thib peb (kev kos duab qhuav) - lub tank dej kos cov hlau tiav lawm. Cov txheej txheem saum toj no tuaj yeem tsim cov hlau galvanized uas muaj zog heev nrog cov ntsiab lus carbon ntawm 0.93-0.97%, txoj kab uas hla ntawm 0.26 hli thiab lub zog ntawm 3921N/mm2. Cov txheej txheem zinc ua lub luag haujlwm hauv kev tiv thaiv thiab lubricating qhov chaw ntawm cov hlau thaum lub sijhawm kos duab, thiab cov hlau tsis tawg thaum lub sijhawm kos duab..
