Nyob rau hauv tus txheej txheem ntawm txhuas smelting thiab rov qab, vim impurities los yog tsis txaus reactants muaj nyob rau hauv cov ntaub ntawv raw, nrog rau cov oxidation thiab txo cov tshuaj tiv thaiv thaum lub sij hawm melting txheej txheem, yuav tsim insoluble impurities nyob rau hauv txhuas kua, uas yog, txhuas slag, cov no. impurities yuav ntab rau saum npoo ntawm cov kua txhuas txhuas, ntawm cov ntsiab lus txhuas nyiaj ntau dua 60%, yog li, nws yog ib qho tsim nyog yuav tsum siv dross xovxwm,sow pwm, dross pan, skim lauj kaub thiab lwm yam khoom siv los txhim kho kev siv cov peev txheej kom txo tau cov khoom pov tseg.
● Dross xovxwm yog ib qho khoom siv tseem ceeb heev rau kev kho aluminium slag. Aluminium slag feem ntau muaj ntau cov hlau txhuas, tab sis sib xyaw nrog cov oxides thiab impurities, cov txheej txheem kev kho ib txwm siv yuav ua rau cov txhuas poob ntau. Lub hauv paus ntsiab lus ntawm Dross Xovxwm yog extrude cov hlau txhuas nyob rau hauv aluminium slag los ntawm lub siab, thiaj li mus cais ntau ntshiab txhuas, uas tsis tsuas yog txhim kho tus nqi rov qab ntawm txhuas, tab sis kuj txo qhov nyuaj ntawm kev kho mob.
Kev ua haujlwm ntawm dross xovxwm yog qhov yooj yim, raws li hom aluminium slag xaiv hom, lub tais slag nrog kub aluminium slag rau hauv slag xovxwm, los ntawm cov neeg kho tshuab quab yuam ntawm slag xovxwm hlau aluminium thiab residue sib cais, cov residue kho feem ntau muaj ib qho me me ntawm txhuas, tuaj yeem siv rau kev rov ua haujlwm thib ob uas siv lub tshuab ua kom sov thiab cov khoom siv zoo sib xws.
● sow pwm yog siv los sau cov kua txhuas thiab daim ntawv txhuas ingots, uas feem ntau yog thauj los yog khaws cia nyob rau hauv qhov ntev los pab txhawb kev rov ua dua tshiab lossis muag khoom. Sow pwm muaj nyob rau hauv ntau qhov sib txawv rau kev xav tau casting.
Nyob rau hauv cov txheej txheem kev kho aluminium slag, tom qab melting thiab degassing kev kho mob, cov kua txhuas yog nchuav rau hauv cov pwm pwm, thiab tom qab txias, aluminium ingots tuaj yeem raug tshem tawm ntawm pwm rau kev tshuaj xyuas thiab kev kho mob.
● Dross lauj kaub yog lub thawv tshwj xeeb rau kev sau thiab thauj cov txhuas slag. Thaum lub sij hawm txhuas smelting txheej txheem, yuav muaj scum nyob rau saum npoo, thiab nws yog tsim nyog los tshem tawm cov txhuas slag los ntawm lub cub tawg thiab tshuaj ntsuam tawm cov slag thiab txhuas.
Dross yias feem ntau yog ua los ntawm cov ntaub ntawv kub-resistant thiab yog tsim los pab txhawb kev sau thiab pov tseg ntawm txhuas slag, tso cai rau kev yooj yim ntawm kev siv forklifts thauj txhuas slag mus rau lub slag xovxwm los yog lwm yam khoom siv.
Dross xovxwm, sow pwm thiab dross lauj kaub yog cov cuab yeej tseem ceeb heev hauv cov txheej txheem txhuas slag rov ua dua tshiab thiab yog qhov ua tau zoo ntawm txhuas rov ua dua tshiab. Ua kom cov txhuas rov qab los nrog Dross Xovxwm, Sow Mould khw muag khoom ua kua txhuas thiab muab pov rau hauv cov khoom siv, thiab cov lauj kaub dross sau thiab kho cov txhuas slag. Kev siv cov khoom siv tsis tuaj yeem txhim kho kev tsim khoom, tab sis kuj tuaj yeem ua kom zoo dua qub ntawm txhuas, txo cov nqi khiav lag luam, tab sis kuj txo cov pa phem ib puag ncig, tsim nyog thiab siv tau zoo tuaj yeem nqa cov txiaj ntsig kev lag luam ntau dua.
