Induction Melting Rauv Rau Kub Platinum Nyiaj Tooj Liab Rhodium Palladium

1. Kev Taw Qhia

Cov cub tawg me me uas muaj peev xwm txij li 2 kg txog 10 kg tau tsim ib qho chaw tseem ceeb hauv ntau yam lag luam. Cov chav me me tab sis muaj zog no tau tsim los ua kom tau raws li qhov xav tau ntawm kev ua haujlwm uas xav tau kev yaj cov hlau me me, muab ntau yam zoo dua li cov txheej txheem loj dua lossis cov txheej txheem ib txwm muaj.

2. Kev Siv Hluav Taws Xob Zoo

2.1 Kev Kub Siab Induction Zaus

Cov cub tawg me me uas siv induction melting ua haujlwm raws li lub hauv paus ntsiab lus ntawm electromagnetic induction. Cov hluav taws xob hloov pauv ntau zaus raug xa mus rau hauv lub kauj, tsim kom muaj lub zog sib nqus. Thaum muab cov hlau tso rau hauv lub zog no, cov hluav taws xob eddy raug tsim hauv cov hlau. Cov hluav taws xob eddy no ntsib qhov tsis kam ntawm cov hlau, tsim cua sov raws li cov qauv Q = I^{2} Rt (qhov twg Q yog cua sov, I yog tam sim no, R yog kev tsis kam, thiab t yog lub sijhawm). Txoj kev ua kom sov no ua haujlwm tau zoo heev vim nws ua kom cov hlau sov ncaj qha los ntawm sab hauv. Piv rau qee lub cub tawg roj ib txwm muaj, tsis tas yuav ua kom sov ib puag ncig ua ntej, txo qhov poob cua sov. Piv txwv li, piv rau lub cub tawg roj me me, lub cub tawg induction melting 5 kg tuaj yeem txuag tau txog li 30 - 40% ntawm lub zog thaum lub sijhawm yaj. Qhov kev txuag hluav taws xob no tsis yog tsuas yog txo cov nqi ua haujlwm xwb tab sis kuj pab txhawb rau kev ruaj khov ib puag ncig los ntawm kev txo kev siv hluav taws xob tag nrho.

3. Kev Ua Kom Tseeb thiab Zoo

3.1 Kev Tswj Kub Kom Tseeb

Ib qho zoo kawg nkaus ntawm cov cub tawg me me no yog lawv lub peev xwm los tswj qhov kub kom raug. Lawv muaj cov txheej txheem ntsuas kub thiab tswj tau zoo heev. Cov neeg ua haujlwm tuaj yeem teeb tsa qhov kub yaj kom raug, feem ntau nyob rau hauv qhov kam rau siab ntawm ± 5 ° C. Qhov no yog qhov tseem ceeb thaum yaj cov hlau uas muaj cov ntsiab lus yaj tshwj xeeb thiab thaum sib xyaw cov hlau, vim tias kev tswj qhov kub kom raug ua kom yaj thiab sib xyaw cov khoom sib txawv zoo. Piv txwv li, thaum yaj ib qho hlau tooj liab thiab zinc tshwj xeeb los tsim tooj dag, kev tswj qhov kub kom raug ua kom qhov sib piv ntawm ob lub hlau raug tswj, ua rau cov khoom zoo thiab sib xws.

3.2 Txo Kev Ua Phem

Kev yaj induction yog ib qho txheej txheem huv si. Vim tias tsis muaj kev sib xyaw ua ke zoo li cov cub tawg roj, muaj kev pheej hmoo tsawg dua ntawm kev coj cov pa phem rau hauv cov hlau yaj. Cov cub tawg uas siv hluav taws xob tuaj yeem tso tawm cov sulfur, nitrogen oxides, thiab cov khoom me me, uas tuaj yeem cuam tshuam nrog cov hlau thiab ua rau muaj cov pa phem. Hauv lub cub tawg me me induction, tsuas yog qhov ua rau muaj kev sib xyaw yog cov hlau nws tus kheej, thiab nrog kev tuav kom zoo, qhov no tuaj yeem txo qis. Qhov no ua rau cov khoom kawg huv dua, uas yog qhov xav tau heev hauv kev lag luam xws li kev ua hniav nyiaj hniav kub thiab kev tsim cov khoom siv hluav taws xob.

4. Kev ywj pheej

4.1 Kev Sib Txuas Ntau Yam Hlau

Cov cub tawg me me uas siv hluav taws xob me me tuaj yeem siv tau ntau yam hlau. Txawm hais tias nws yog cov hlau ferrous xws li hlau thiab hlau lossis cov hlau uas tsis yog ferrous xws li txhuas, tooj liab, thiab cov hlau muaj nqis xws li kub thiab nyiaj, cov cub tawg no tuaj yeem hloov kho kom tau raws li qhov xav tau ntawm cov khoom sib txawv. Txhua cov hlau muaj qhov sib txawv ntawm qhov melting, thiab lub zog thiab qhov kub ntawm lub cub tawg induction tuaj yeem hloov kho tau yooj yim. Piv txwv li, txhuas yaj ntawm kwv yees li 660 ° C, thaum kub yaj ntawm kwv yees li 1064 ° C. Lub cub tawg tuaj yeem raug programmed kom ncav cuag thiab tswj qhov kub kom haum rau txhua cov hlau, ua rau nws yog ib qho cuab yeej siv tau ntau yam hauv cov chaw ua haujlwm uas cuam tshuam nrog cov haujlwm sib txawv ntawm cov hlau.

4.2 Qhov Loj Sib Txawv ntawm Cov Khoom Siv

Nrog rau qhov muaj peev xwm ntawm 2 kg txog 10 kg, cov cub tawg no haum rau ntau qhov kev xav tau ntawm ntau qhov loj me. Cov lag luam me lossis cov neeg nyiam ua si uas tsuas yog xav tau yaj ob peb kilograms ntawm cov hlau ib zaug tuaj yeem tau txais txiaj ntsig los ntawm cov qauv muaj peev xwm qis dua. Ntawm qhov tod tes, cov lag luam me - mus rau - nruab nrab - uas xav tau cov khoom loj dua me ntsis tab sis tseem nyob hauv 10 - kg kuj tuaj yeem pom cov cub tawg no kom haum zoo. Qhov kev ywj pheej ntawm qhov loj me no tso cai rau kev tsim khoom pheej yig vim tias tsis tas yuav nqis peev ntau dhau rau hauv lub cub tawg loj dua rau kev tsim khoom me me.
