Kub-dip galvanizing, tseem hu ua kub-dip zinc txheej los yog kub-dip zinc plating, yog ib qho zoo hlau tiv thaiv kev tiv thaiv feem ntau siv rau cov khoom siv hlau hauv ntau yam lag luam. Nws cuam tshuam rau cov khoom siv hlau derusted rau hauv molten zinc ntawm kwv yees li 500 degree, tso cai rau cov zinc txheej ua raws li cov khoom siv hlau, yog li ua tiav kev tiv thaiv corrosion. Cov txheej txheem kub-dip galvanizing muaj xws li: tiav cov khoom pickling - dej ntxuav - ntxiv pab plating tov - ziab - dai rau plating - txias - passivation - tu - polishing - tiav ntawm kub-dip galvanizing. Kub-dip galvanizing tau hloov zuj zus los ntawm cov txheej txheem kub-dip qub thiab tau siv hauv kev lag luam txij li Fabkis tau siv rau xyoo 1836, nrog rau keeb kwm ntev dua 170 xyoo. Nyob rau hauv peb lub xyoos dhau los, nrog rau kev loj hlob sai ntawm txias-kuav los tiag steel strips, kub-dip galvanizing kev lag luam tau undergone loj expansion.
Rau kub-dip galvanizing ntawm steel kav, iav-disk tag nrho immersion semi-automatic galvanizing txoj kev yog saws, siv txhua yam hauv paus ntsiab lus ntawm insertion, nias, spiraling, extraction, thiab lifting kom tiav cov txheej txheem kub-dip galvanizing.
Kev tswj cov txheej txheem: Qhov kub ntawm cov zinc tov yuav tsum tswj ntawm {{0}} degree ; lub sij hawm immersion yuav tsum tswj ntawm 30-60 vib nas this; aluminium ntxiv (cov ntsiab lus txhuas nyob rau hauv zinc tov nto: 0.01-0.02%).
Cov zinc ingots siv yuav tsum ua raws li lub teb chaws tus qauv Zn 0-3.
Kev tu thiab kev tswj xyuas tsis tu ncua yog qhov tseem ceeb los xyuas kom muaj kev ntseeg tau ntawm qhov ntxig, nias kauv, rho tawm, thiab nqa cov khoom siv. Lubrication ntawm lub tog raj kheej yuav tsum tau kho kom zoo, thiab qhov siab thiab lub kaum sab xis ntawm cov yeeb nkab galvanized distributor yuav tsum tau hloov kho kom zoo dua cov khoom siv.
Qhov chaw ntawm qhov sib thooj hloov pauv yuav tsum yog qhov tseeb; thermocouple xov hlau thiab meters yuav tsum yog ib qho kev sib koom ua qauv; txwv tsis pub, qhov kub tsis raug yuav yog qhov tseem ceeb. Lub tes tsho tiv thaiv ntawm lub thermocouple yuav tsum tau kuaj xyuas thiab hloov ntau zaus.
Cov neeg ua haujlwm ntawm cov tswj vaj huam sib luag yuav tsum manually kho qhov ceev raws li kev ua haujlwm ntawm cov khoom siv thiab tes taw kom tiv thaiv cov yeeb nkab jamming.
Cov cuab yeej siv los ntawm cov neeg ua haujlwm hauv lub cub tawg yuav tsum tau preheated ua ntej siv los tiv thaiv zinc splashing thiab raug mob; tsis tu ncua xyuas cov kav hlau uas poob rau hauv lub lauj kaub thiab tshem tawm tam sim ntawd; kho cov khoom siv raws sij hawm kom tsis txhob muaj cov yeeb nkab jamming thiab ua kom cov khoom ruaj ntseg.
Thaum ntxiv zinc rau lub lauj kaub zinc, cov zinc ingots yuav tsum tau preheated. Ntxiv zinc rau hauv pob khoom yog txwv tsis pub nruj; ntxiv tsis pub ntau tshaj tsib ingots txhua zaus. Maj mam xaub cov zinc ingots longitudinally tiv thaiv phab ntsa ntawm lub lauj kaub zinc kom tsis txhob ua puas lub lauj kaub thiab txaws zinc, uas tuaj yeem ua rau raug mob. Hlau-raws li cov ntaub ntawv yog nruj me ntsis txwv tsis pub poob rau hauv zinc tov los tiv thaiv cov tiam ntawm ib tug loj npaum li cas ntawm zinc slag.
Thaum melting zinc, cua sov yuav tsum tau siv maj mam, tsis txhob muaj cua sov sai, uas tuaj yeem ua rau lub lauj kaub galvanizing puas thiab ua rau lub emission ntawm zinc vapor ntau heev. Kev nqus pa ntau dhau ntawm cov pa phem no tuaj yeem ua rau "hlau fume fever." Thaum lub sij hawm zinc melting txheej txheem, ib zaug zinc ncav cuag qhov kub siab, tsis txhob siv koj txhais tes los do cov zinc blocks kom tsis txhob kub hnyiab; siv cov cuab yeej tsim nyog hloov.
Tsis tu ncua tshem cov zinc tshauv los ntawm qhov chaw ntawm cov tshuaj zinc. Thaum scraping, maj mam txhuam qhov saum npoo ntawm cov zinc tov nrog lub rooj sib tsoo uas tsis tau nplawm heev kom tsis txhob nce zinc tshauv. Lub scraping board yuav tsum tsis txhob kov cov kav hlau thaum lub sij hawm immersion los yog extraction los tiv thaiv kev raug mob los yog cov khoom puas.
Zinc blocks, zinc fragments, zinc coj tawm thaum lub sij hawm galvanizing, thiab zinc ntws tawm ntawm cov kav hlau nyob rau hauv lub cub tawg yuav tsum tau zoo tu qab tso thiab xa rov qab mus rau lub lauj kaub tam sim ntawd kom txo tau kub los ntawm zinc lub lauj kaub.
Thaum ntxiv aluminium ingots rau saum npoo ntawm zinc tov, xyuas kom meej txawm tias cov khoom siv txhuas los ntawm kev txav cov ingots rov qab thiab tawm ob peb zaug.
Txhawm rau pab tshem tawm slag thiab zinc rho tawm, 20 tons ntawm txhuas yuav tsum muab tso rau hauv lub lauj kaub zinc.
Preheat lub tshuab tshem tawm slag ua ntej siv. Khaws cov zinc slag hauv ntau qhov sib txawv. Qhov kub rau kev tshem tawm slag yuav tsum tswj siab tshaj 455 degree. Siv cov cuab yeej tshwj xeeb thaum ua haujlwm ntawm lub tshuab slag grabbing, thiab sawv nrog taw hauv "T" txoj hauj lwm, ib meter deb ntawm lub lauj kaub zinc.
Cov txheej txheem kub-dip galvanizing yuav tsum tau precision. Yog li ntawd, thaum lub sij hawm kub-dip galvanizing ntau lawm, nws yog ib qho tseem ceeb rau kev ua hauj lwm efficiency. Hauv lwm lo lus, ntau dua ntawm daim lossis tonnage ib lub sijhawm ua rau tus nqi qis dua, thiab rov ua dua.
