To taub Dross Pans
Ua ntej peb tshawb nrhiav txoj hauv kev los txhim kho lub neej ntawm cov lauj kaub dross, nws yog ib qho tseem ceeb kom nkag siab txog lawv txoj haujlwm thiab cov qauv. Cov khib nyiab no feem ntau yog tsim los ntawm cov ntaub ntawv uas tuaj yeem tiv taus qhov kub thiab txias, xws li cam khwb cia hlau lossis hlau. Lawv tuaj nyob rau hauv ntau yam duab thiab qhov ntau thiab tsawg, tab sis lawv lub hom phiaj tseem ceeb yog khaws cov dross - sib tov ntawm txhuas oxide, txhuas nitride, thiab lwm yam impurities. Kev tswj kom zoo dross yog qhov tseem ceeb los xyuas kom meej qhov zoo thiab purity ntawm qhov kawg aluminium ingots.
1. Kev tuav thiab tu kom zoo
Ib qho ntawm cov kauj ruam tseem ceeb hauv kev nce lub neej ntawmdros pansyog tu thiab ceev faj tuav. Dross pans yuav tsum tau kho nrog kev saib xyuas, tsis txhob kov qhov hnyav uas tuaj yeem ua rau tawg lossis puas tsuaj. Kev tshuaj xyuas niaj hnub yuav tsum tau ua los txheeb xyuas cov cim ntawm kev hnav thiab tsim kua muag, thiab kev kho lossis hloov pauv yuav tsum tau ua kom sai.
2. Kev tswj qhov kub thiab txias
Kev tswj xyuas qhov kub kom tsim nyog thaum lub sij hawm txhuas casting thiab refining txheej txheem yog qhov tseem ceeb tshaj plaws. Qhov kub thiab txias hloov pauv tuaj yeem ua rau muaj kev ntxhov siab tsis zoo ntawm cov khoom siv hauv lub lauj kaub, ua rau nws tsis muaj zog thaum lub sijhawm. Ua tib zoo saib xyuas thiab tswj qhov kub thiab txias tuaj yeem txuas ntxiv lub lauj kaub lub neej.
3. Cov txheej txheem tshem tawm kom zoo
Cov txheej txheem tshem tawm dross zoo yog qhov tseem ceeb rau kev ua kom lub neej ntev ntawm dross pans. Kev siv cov cuab yeej tshwj xeeb thiab cov txheej txheem rau kev tshem tawm dross tsis tsuas yog ua kom lub lauj kaub tseem ua haujlwm tau zoo tab sis kuj txo qis qhov muaj peev xwm rau kev puas tsuaj thaum lub sijhawm tshem tawm. Kev cob qhia txaus ntawm cov neeg ua haujlwm hauv cov txheej txheem tshem tawm kom raug yog qhov tseem ceeb.
4. Cov txheej txheem ntxuav kom zoo
Kev tu lub lauj kaub tsis tu ncua yog qhov tseem ceeb los tiv thaiv kev sib sau ntawm cov pob zeb thiab lwm yam impurities. Yog tias sab laug tsis muaj neeg saib xyuas, dross tuaj yeem sib sau ua ke, txo qis lub lauj kaub dross efficiency thiab muaj feem ua rau ua tsis tiav ntxov. Tsim kom muaj kev tu txhua hnub yog qhov tseem ceeb rau lub neej ntev ntawm lub lauj kaub dross.
5. Cov txheej txheem tiv thaiv
Kev siv cov txheej txheem tiv thaiv rau saum npoo ntawm lub lauj kaub dross tuaj yeem ua rau nws tsis kam mus rau qhov cuam tshuam corrosive ntawm molten aluminium. Cov txheej txheej no ua haujlwm tiv thaiv, tiv thaiv lub lauj kaub los ntawm cov tshuaj lom neeg thiab txo qhov hnav thiab tsim kua muag. Cov kws tshaj lij sab laj tuaj yeem pab txheeb xyuas cov txheej txheem tsim nyog tshaj plaws rau koj daim ntawv thov tshwj xeeb.
6. Kev xaiv cov khoom zoo
Thaum yuav khoom tshiabdros pans, xaiv cov khoom zoo thiab kev tsim kho kom zoo yog qhov tseem ceeb. Txawm hais tias nws yuav yog qhov kev nqis peev tseem ceeb tshaj plaws, kev xaiv cov lauj kaub uas ua los ntawm cov ntaub ntawv zoo tshaj tuaj yeem txuas ntxiv lawv lub neej thiab kev ua haujlwm tag nrho, ua rau lawv xaiv qhov zoo dua rau lub sijhawm ntev.
7. Kev tshuaj xyuas tsis tu ncua thiab kuaj
Kev tshuaj xyuas thiab kev sim tsis tu ncua yog tsim nyog los txheeb xyuas cov cim qhia ntawm cov khoom siv degradation, hnav, lossis teeb meem ntawm cov qauv. Cov txheej txheem kuaj tsis muaj kev puas tsuaj, xws li kev kuaj ultrasonic, tuaj yeem ua haujlwm los soj ntsuam cov yias dross kev ncaj ncees yam tsis muaj kev puas tsuaj. Kev tshawb nrhiav cov teeb meem raws sij hawm tuaj yeem ua rau muaj txiaj ntsig zoo los yog hloov pauv.
8. Kev cob qhia cov neeg ua haujlwm
Cov tib neeg uas muaj lub luag haujlwm rau kev khiav hauj lwm thiab kev tswj xyuas lub lauj kaub dross ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab lawv lub neej. Kev cob qhia kom raug ua kom cov neeg ua haujlwm paub txog cov kev coj ua zoo tshaj plaws rau kev tuav, tu, thiab tswj cov lauj kaub. Qhov no tuaj yeem pab tiv thaiv kom tsis txhob muaj kev puas tsuaj thiab xyuas kom meej tias covdros panssiv tau zoo.
9. Kev xav txog ib puag ncig
Ib puag ncig yam tseem ceeb, xws li raug dej noo thiab tshuaj lom neeg, tuaj yeem cuam tshuam lub neej ntawmdros pans. Tiv thaiv dross pans los ntawm cov dej noo ntau dhau thiab cov khoom corrosive yog qhov tseem ceeb heev kom ncua lawv txoj sia. Tsis tas li ntawd, kev tswj xyuas qhov chaw ua haujlwm huv thiab tsis muaj paug tuaj yeem pab tiv thaiv kev hnav thiab tsim kua muag ntxov.
10. Kev hloov kho tshiab tsis tu ncua thiab kev tsim kho tshiab
Raws li thev naus laus zis thiab cov ntaub ntawv txuas ntxiv mus, nyob rau niaj hnub nrog cov kev hloov tshiab tshiab hauv aluminium ingot pwm dross pan tsim thiab kev tsim kho yog qhov tseem ceeb.
Txhawm rau tiv thaiv qhov shrinkage qhov kub ntawm qhov sib koom ua ke ntawm lub tank slag, phab ntsa tuab feem ntau yog tsim los ntawm qhov qis ntawm riser, thiaj li ua kom tiav cov khoom sib txuas, thiab thaum kawg lub qhov shrinkage yog pauv mus rau riser. Cov txheej txheem no yog hu ua kev pab nyiaj siv thev naus laus zis hauv cov txheej txheem, thiab cov txheej txheem ntawm kev teeb tsa cov nyiaj pab hlau yog qhov yooj yim thiab ncaj qha, uas tuaj yeem tshem tawm qhov shrinkage qhov thiab slag inclusion defects uas yuav tshwm sim nyob rau hauv qhov kub sib koom ua ke.
Xaus
Dross pansyog cov cuab yeej tseem ceeb hauv kev lag luam aluminium casting thiab refining, thiab lawv cov kev tu thiab kev saib xyuas kom zoo yog qhov tseem ceeb hauv kev ua kom lawv lub neej ntev. Los ntawm kev ua raws li cov tswv yim uas tau teev tseg hauv tsab xov xwm no, suav nrog kev saib xyuas tsis tu ncua, tswj qhov kub thiab txias, tiv thaiv txheej, thiab kev tuav kom zoo, koj tuaj yeem ua rau lub neej ntawm txhuas ingot pwm dross pans. Qhov no tsis tsuas yog txo cov nqi ua haujlwm tab sis kuj lav qhov tsim cov khoom zoo aluminium ingots. Kev nqis peev hauv lub neej ntev ntawm dross yias thaum kawg muaj txiaj ntsig zoo rau kev lag luam thiab ib puag ncig, ua rau nws muaj kev txawj ntse thiab muaj lub luag haujlwm xaiv.
