Cov txheej txheem tsim khoom ntawm cov yeeb nkab steel kub-dip galvanized

1.Kev ntxuav alkali: qee cov kav hlau muaj cov roj av ntawm qhov chaw, yog li yuav tsum tau ntxuav alkali.

2.Pickling: hydrochloric acid yog xaiv rau pickling kom tshem tawm cov tawv nqaij oxide ntawm cov yeeb nkab hlau.

3.Yaug: feem ntau yog kom tshem tawm cov kua qaub thiab hlau ntsev uas txuas rau ntawm cov yeeb nkab hlau.

4.Cov khoom siv dipping: lub luag haujlwm ntawm flux yog tshem tawm txhua yam tsis huv ntawm qhov chaw ntawm cov yeeb nkab hlau, xyuas kom meej tias muaj kev sib cuag huv ntawm cov yeeb nkab hlau thiab cov tshuaj zinc, thiab tsim ib txheej zoo.

5.Kev ziab: feem ntau yog los tiv thaiv cov yeeb nkab hlau kom tsis txhob raug muab tso rau hauv lub lauj kaub zinc thiab tua.

6.Kub dip galvanizing: qhov kub ntawm cov kua zinc hauv lub lauj kaub zinc yuav tsum tau tswj hwm nruj me ntsis ntawm 450 + 5 ° C, cov yeeb nkab hlau yuav tsum tau muab tso rau hauv lub cub tawg galvanizing thiab dov rau hauv peb lub zinc dipping spirals hauv lub tshuab galvanizing. Peb lub spirals muaj ntau theem sib txawv, ua rau cov yeeb nkab hlau inclined rau ntawm cov spirals. Nrog rau kev tig ntawm cov spirals, cov yeeb nkab hlau txav mus rau hauv qab ntawm ib sab los ua lub kaum sab xis ntawm inclination, thiab tom qab ntawd nkag mus rau hauv lub dab dej zinc, txuas ntxiv mus rau hauv qab, thiab cia li poob rau ntawm txoj kab swb hauv lub lauj kaub zinc; Thaum cov yeeb nkab hlau raug tsa mus rau qhov chaw sib xyaw magnetic, nws yuav raug rub thiab tsiv mus rau txoj kev rub lub log.

7.Tshuab sab nraud: cov yeeb nkab hlau hla dhau lub nplhaib tshuab sab nraud kom nias cov huab cua thiab tshuab cov kua zinc ntau dhau ntawm cov yeeb nkab hlau kom tau txais qhov zoo nkauj thiab huv si.
8.Rub tawm: Tus nqi ntawm zinc tuaj yeem tswj tau thiab kev siv zinc tuaj yeem txo qis los ntawm kev txo qhov ceev rub tawm kom raug.
9.Tshuab sab hauv: tshem tawm cov kua zinc ntau dhau ntawm sab hauv ntawm cov yeeb nkab hlau kom tau txais qhov chaw du thiab huv si. Cov kua zinc uas raug tshem tawm yuav ua rau cov hmoov zinc rov ua dua tshiab.
10.Dej txias: qhov kub ntawm lub tank dej txias yuav tsum tswj tau ntawm 80 ℃, thiab cov yeeb nkab galvanized yuav tsum txias.
11.Kev Ua Kom Dhau: cov tshuaj passivation raug txau rau ntawm cov yeeb nkab tiav ntawm lub nplhaib tshuab kom ua rau qhov chaw ntawm cov yeeb nkab passivated. Tom qab lub nplhaib tshuab sab nraud, cov tshuaj passivation ntau dhau raug tshuab tawm nrog cua compressed.
12.Kev Tshuaj Xyuas: cov yeeb nkab galvanized poob rau ntawm lub rooj zaum tshuaj xyuas, tom qab kev tshuaj xyuas, cov yeeb nkab galvanized uas ploj lawm raug muab tso rau hauv lub pob tawb pov tseg, thiab cov yeeb nkab tiav lawm raug ntim thiab muab tso rau hauv qhov chaw khaws cia.
