Kev tsim cov txheej txheem ntawm cov ntsia hlau yog muab faib ua 7 kauj ruam, xws li, pob ntseg, deev, kos duab, sib sau, dov, tshav kub kho qib ntu kho.
Txhim kho txoj haujlwm: Thawj txheej txheem tshuaj yog muab tso rau hauv lub tshuab ua kom sov thiab kaw nrog lub hau ua kom sov. Ib lub cub tawg tau 8.4 tons ntawm tib lub sijhawm. Tom qab ntawd maj mam nce tus kub mus rau qhov kev ntsuas kub, qhov no yuav siv sij hawm 3-4 teev. Tom qab ntawd, siv qhov kub qeeb kom 550 degree rau 3-4 teev thiab cia cov khoom kom txias rau chav sov. Cov txheej txheem no tuaj yeem kho cov qauv ntawm crystalline, txo qhov nyuaj thiab txhim kho qhov kev ntsuas kub ntawm cov hlau.
Pickling Process: Lub hom phiaj ntawm cov kua qaub ntxuav yog tshem tawm cov oxide zaj duab xis los ntawm cov xaim. Tam sim no tag nrho disk yog invaded nyob rau hauv chav tsev kub thiab peb hydrochloric acid tso tsheb hlau luam nrog ib tug concentration ntawm 20-35 feeb. Tom qab ntawd siv dej ntshiab kom pom tseeb cov hydrochloric acid corrosion rau ntawm cov hlau. Thiaj li yuav ua rau zaj yeeb yaj kiab ua ib qho txheej txheem ntau dua, oxalic acid yog siv los ua kom cov kev ua ntawm cov hlau. Lub disc yog infiltrated nrog phosphate, thiab cov nplaim ntawm cov hlau yog hu nrog ib cov tshuaj conversion tshuaj kho. Cov tshuaj kho thiab cov hlau tau tsim los ua ib qho chaw, uas tau txuas nrog cov ntsia hlau nto ua ib zaj duab xis. Tom qab ntawd siv cov dej huv kom tshem tawm cov khoom seem. Tom qab ntawd siv cov roj lubricating kom nws cov lubricity.
Teeb duab cov kab xev: Siv cov duab zoo thiab ntxhib duab ntawm qee cov khoom kom rub lub phaj khoom mus rau ntawm daim phiaj xaim. Cov txheej txheem no yog siv rau cov xov hlau uas siv hauv cov ntsuas loj, ceev, thiab cov hniav tuav.
Kev Teeb Meem: Muaj ob hom hexagon bolts: ib hom plaub hom plaub-stroke los yog peb hom three-stroke, tab sis peb hom three-stroke. Cov ntsia hlau yog ob lub punch. Tom qab ntawd kub, kub yog muab faib ua peb kauj ruam, thawj kauj ruam ntawm qhov khoom rau hauv qhov cua kub twj ywm raws li cov khoom siv qhia ua cua sov lub sij hawm thiab qhov kub. Hauv ob kauj ruam, tom qab cua sov, qhov khoom hloov mus rau ib qho pwm rau molding. Tom qab ntawd siv ib lub txiv tsawb kom nyem nws.
Kev Txheeb Milling: Cov khoom ua tiav ib nrab khoom uas tau tsim muaj yog screwed los yog khawm rau qhov xov uas xav tau.
Cov txheej txheem cua sov: Txhawm rau txhawm rau txhim kho cov khoom siv dag zog ntawm cov khoom, tshem tawm txoj kev ntxhov siab thiab txhim kho cov txheej txheem hlau yuav tsum tau kho cov khoom kub. Raws li qhov xav tau ntawm cov khoom, koj tuaj yeem siv ob qho kev kho mob ua ntej sov thiab kev kho mob kawg.
Cov txheej txheem deg: Ntawm lub tshuab electrophlating, kub-ntxeem galvanization, mechanical galvanization los tsim ib txheej ntawm cov nplais ntawm cov khoom, yog li ntawd cov khoom seem pom, cov teebmeem tiv thaiv los ntawm corrosion.
