Dab tsi yog qhov txawv txav phenomena ntawmdawb aluminium oxidenyob rau hauv pem hauv ntej ntawm lub qhov cub smelting thiab yuav ua li cas lawv yuav tsum tau nrog? Hnub no kuv yuav muab lus qhia luv luv rau koj.
1. Arc tawg
Nta: Tsis muaj cov zaub tam sim no, tsis muaj suab nrov hauv qhov cub, tsis muaj flash ntawm electrodes.
Ua rau: Cov pas nrig arcing tsis kho zoo, tus pas nrig raug tshem tawm ntxov dhau, thiab tsis muaj yaj; cov khoom yog ntxiv ceev heev, cov txhuas cov pa oxygen yog raus thiab thaiv txoj kev tam sim no, cov tshuaj tiv thaiv ntoo khaub lig ua ib qho nyuaj, thiab cov electrode raug thaiv los ntawm kev poob.
Kev daws: Xyuas ua ntej pib lub arc; tshem tawm cov pa roj carbon pas nrig tom qab lub qhov cub txias yog qhov ruaj khov; them sai sai rau kev pub mis ceev; txav cov electrode nquag thaum hlua lub qhov cub; thiab rov pib lub arc.
2. Skewers
Nta: Cov kua molten ntws sai sai rov qab los rau hauv cov khoom siv hmoov, nplawm ntau cov hmoov txhuas oxide, qee zaum ua rau muaj kev cuam tshuam, uas feem ntau tshwm sim hauv 10 teev tom qab pib lub qhov cub.
Yog vim li cas: Cov ntaub ntawv txheej ntawm ntug yog thicker, lub melting nto nyob rau hauv qab ntawm lub cub tawg yog me me, thiab cov khoom noj tsis sib npaug, ua rau cov cua sov tsis sib xws. Thaum cov yaj tuaj rau hauv kev sib cuag nrog cov phab ntsa hauv qhov cub hauv qee qhov lossis cov cua siab hauv lub qhov cub kub, cov yaj tuaj yeem tawm thiab cov khoom txias txias tuaj.
Kev daws: Siv cov hluav taws xob qis dua hauv thawj ob peb teev, nthuav cov melting nto, thiab nce cov kua ntim; Nyob rau hauv cov xwm txheej hnyav, rhuav tshem cov pob txha tawv, theem tus nqi, thiab ua kom zoo.
3. Tua tawm
Nta: Muaj lub suab nrov nrov hauv lub qhov cub, thiab cov roj kub kub thiab cov pob hluav taws raug tshem tawm. Thaum tsis muaj qhov cub tawg, lub plhaub ntawm lub cub tawg yuav tig liab ntawm qhov chaw uas tawg tau raug rho tawm haujlwm. Hauv qhov xwm txheej hnyav, nws yuav ua rau lub qhov cub tawg.
Ua rau: Lub qhov cub hauv qab thiab qhov cub hauv ob sab phlu yog ntub, cov ntaub ntawv raw yog ntub, cov dej sab nraud infiltrates, cov khoom txheej yog tuab heev, thiab kev ua haujlwm tsis zoo ua rau huab cua ntau dhau hauv qhov cub.
Kev daws: Tiv thaiv kom tsis txhob ya raws hauv qab ntawm qhov cub; tswj cov dej noo ntawm cov ntaub ntawv raw; ntxiv dag zog rau kev ua haujlwm kom ntseeg tau tias cov khoom siv sib xws; nce tus nqi ntawm cov dej txias rau cov cua sov uas tsis muaj cua sov; tuav lawv raws sij hawm kom tawg agglomerates thiab smoothen tus nqi.
4. "Tub tawm lub qhov cub hauv ob sab phlu"
Nta: Cov kua molten reacts nrog rau lub qhov cub hauv ob sab phlu, thiab cov kua molten dhia hla cov khoom txheej. Nyob rau hauv cov xwm txheej hnyav, nws yog ib qho nyuaj rau suppress cov khoom siv ntxiv, thiab txawm tias qhov cub tawg tuaj yeem tshwm sim.
Ua rau: Kev ua haujlwm tsis raug, kev noj tsis sib luag lossis tsis xis nyob, cov khoom nyias nyias txheej sab nraud ntawm lub tshuab hluav taws xob, cov khoom siv hluav taws xob ze ze rau lub tshuab hluav taws xob, qhov hluav taws xob tsawg dhau, thiab lwm yam.
Kev daws: Ntxiv dawb aluminium oxide pov tseg rau sab nraud ntawm cov electrode, nrog rau qhov loj me ntawm 20-40mm; kho qhov voltage lossis electrode nrug; txo qhov tam sim no, txo lub zog tawm tswv yim, nce cov dej txias; nres lub cub tawg yog tias tsim nyog.
