Daim duab txheej txheem ntawm Galvanized steel hlau
lGalvanizing ua ntej kos cov txheej txheem:Txhawm rau txhim kho kev ua tau zoo ntawm Galvanized steel hlau, cov txheej txheem ntawm cov khoom kos hlau xaim rau cov txhuas annealing tom qab txhuas yog hu ua plating ua ntej kos duab. Cov txheej txheem ntws tawm yog: cov hlau hlau - txhuas quenching - galvanizing - kos duab - tiav steel hlau. Cov txheej txheem ntawm thawj plating thiab tom qab ntawd kos duab yog txoj kev luv tshaj plaws hauv txoj kev kos duab ntawm galvanizing thiab electrogalvanizing thiab tom qab ntawd kos duab. Cov khoom siv tshuab hluav taws xob ntawm cov kub galvanized steel hlau tom qab kos duab yog zoo dua li ntawm cov hlau xaim tom qab kos duab. Ob qho tib si tuaj yeem tau txais nyias thiab hnav zoo nkauj zinc txheej, txo zinc tau thiab teeb lub teeb ntawm cov kab galvanizing.
lIntermediate Galvanizing Post cov txheej txheem kos duab:Lub Intermediate Galvanizing Post cov txheej txheem kos duab yog: cov hlau hlau - txhuas kos - galvanizing - galvanizing - galvanizing kos - theem ob - tiav steel hlau hlau. Lub feature ntawm nruab nrab plating tom qab kev kos duab yog tias cov txhuas quenched steel hlau yog galvanized tom qab ib qho kev kos duab thiab tom qab ntawd kos rau cov khoom tiav ob zaug. Galvanizing yog nruab nrab ntawm ob daim duab kos, yog li nws yog hu ua nruab nrab plating ,. Lub zinc txheej ntawm cov hlau hlau tsim los ntawm kev plating nruab nrab thiab tom qab ntawd kos duab yog tuab dua li uas tau tsim los ntawm plating thiab tom qab ntawd kos duab. Tag nrho cov kev nqus tau (los ntawm cov txhuas quenching rau cov khoom tiav) ntawm kub dip galvanized steel hlau tom qab plating thiab kos duab yog siab dua li ntawm cov hlau xaim tom qab plating thiab kos duab.
lSib tov galvanizing txheej txheem:Txhawm rau tsim cov ultra-siab lub zog (3000 n / mm2) galvanized steel hlau, "sib xyaw galvanizing thiab kos duab" yuav tsum tau saws. Cov txheej txheem raug ntws yog raws li hauv qab no: Lead quenching - Proster Dressing - Tertiary teeb (qhuav duab) - dej tank kos duab tas lawm steel hlau. Cov txheej txheem saum toj no tuaj yeem tsim hluav taws xob ultra-siab galvanized steel hlau nrog cov ntsiab lus carbon hlau ntawm 0.26mm thiab lub zog ntawm 3921n / hli2. Lub Zinc Txheej ua lub luag haujlwm hauv kev tiv thaiv thiab lubricating ntawm cov hlau xaim thaum lub sijhawm kos, thiab xaim tsis tawg thaum kos duab.
