(1) Zinc slag yog tsuas yog tsim los ntawm cov tshuaj tiv thaiv ntawm cov hlau, thiab lub hauv paus loj ntawm cov hlau hauv cov kua zinc yog lub hmoov hlau nyob rau saum npoo ntawm cov hlua hlau. Nws yog ib qho tsim nyog los ua kom qhov kev ua kom huv ntawm kev tsiv teb tsaws thiab tshem tawm tag nrho cov saum npoo ntawm cov hlau hlau. Ntawm khib nyiab.
(2) Lub ntsuas kub ntawm zinc cov lauj kaub yuav tsum muaj kev tswjhwm nruj, tsis pub tshaj 4700C, thiab qhov hloov ntawm qhov kub ntawm qhov zinc kua yuav tsum raug tswj me me li sai tau.
(3) Qhov ntsuas kub ntawm qhov hlau hlau nkag mus rau hauv lub lauj kaub zinc yuav tsum ua kom nruj. Yog hais tias qhov ntsuas kub ntawm cov hlau xaim ntau dua 200C lossis ntau dua ntawm cov kua zinc, qhov nyiaj ntawm zinc dross tsim yuav nce ntxiv.
(4) Tswj nruj siv cov txhuas cov ntsiab lus ntawm zinc kua. Cov ntsiab lus tsawg dhau los ntawm aluminium yuav ua rau kom muaj cov hlau yaj ntau hauv cov kua zinc rau saum npoo ntawm cov hlau, thiab tag nrho cov xov tooj ntawm zinc dross yuav nce ntxiv, thiab xaum qab yuav tseem ua tau. Cov ntsiab lus aluminium ntau dhau yuav txo solubility ntawm hlau hauv cov zinc tov thiab nce cov nag lossis daus ntawm zinc dross. Nyob rau tib lub sijhawm, aluminium nws tus kheej yog yooj yim rau oxidize thiab daim ntawv txiav plaub hau. Txo kev hloov ntawm cov ntsiab lus aluminium hauv cov kua zinc, thiab qhov kev hloov ntawm lub aluminium cov ntsiab lus tseem yuav txhawb nqa lub cim ntawm cov hlau xaim.
