Cov txheej txheem ntawm tshem impurities ntawm qhov chaw ntawmmagnesium ingotthiab ntxiv cov yeeb yaj kiab los tiv thaiv oxidation. Qhov saum npoo ntawm magnesium ingot yog yooj yim corroded thaum raug rau huab cua. Tsis tas li ntawd, qee qhov impurities nyob rau saum npoo ntawm magnesium ingot, xws li inorganic chloride flux thiab electrolyte, kuj yuav ua rau muaj zog magnesium. Yog li ntawd, magnesium ingots uas tsim los ntawm refining yuav tsum tau kho kom zoo nto tiv thaiv kom tsis txhob muaj corrosion ntawm magnesium ingots thaum lub sij hawm cia. Txoj kev kho deg ntawm magnesium ingot sib txawv nrog nws lub sijhawm cia thiab cov neeg siv khoom xav tau.
Magnesium ingot zoo li yuav tsum tau: du thiab ci ntsa iab, tsis muaj oxidation point, tsis pom tseeb shrinkage qhov
Los ntawm qhov kev xav ntawm kev tiv thaiv ib puag ncig, nws yog qhov zoo dua los siv sulfuric acid pickling rau nplua magnesium pickling, vim tias nitric acid yuav tsim nitrogen oxides thiab ua paug rau huab cua.
Pickling txheej txheem
1. Pickling npaj:
1.1 Cov cuab yeej: yas crane, stainless hlau tawb, pickling tank, sulfuric acid;
1.2 Kev npaj kev nyab xeeb: cov hnab looj tes roj hmab thiab kev nyab xeeb nyob deb
2. Nrog acid:
2.1 Ntxuav lub tank pickling nrog dej huv ob peb zaug kom paub tseeb tias tsis muaj khib nyiab, khoom noj khoom haus thiab plua plav hauv lub tank;
2.2 Sau cov dej ntshiab peb-quarters ntawm txoj kev;
2.3 Sau lub tank pickling nrog dej, thiab npaj cov kua pickling raws li tus qauv sib piv, txog li peb feem plaub ntawm lub tank pickling;
3. Nruab ingot:
3.1 Muab lub tawb stainless hlau rau ntawm lub laub;
3.2 Sau magnesium ingot rau hauv lub tawb stainless;
3.3 thawb lub laub hauv qab lub kaus mom;
3.4 Pib lub kaus mom, nqa lub tawb stainless hlau, thiab maj mam txav mus rau lub pas dej ua ke;
