Graphite shreglesyog ntau yam thiab cov cuab yeej tseem ceeb hauv kev lag luam xws li metallurgy, chemistry thiab cov hniav nyiaj hniav kub ua. Nws yog tsim los tiv thaiv tsis tshua muaj siab thiab nquag siv rau yaj, cam khwb cia thiab smelt ntau cov ntaub ntawv. Yog tias koj tshiab siv graphite crucibles, lossis tsuas yog xav kom koj cov txheej txheem zoo tag nrho, cov lus qhia no yuav taug kev theem zuj zus, ua kom koj npaj tau txhij txhua txhua tus.
1. Xaiv cov cim graphite crucite:
Xaiv txoj ke graphite crucable yog qhov tseem ceeb kom tau txais cov txiaj ntsig zoo tshaj plaws. Xav txog cov ntaub ntawv koj yuav siv thiab qhov ntsuas kub. Cov tawv ntoo sib txawv yog tsim los daws cov ntsuas kub tshwj xeeb thiab cov khoom siv, xws li kub, nyiaj lossis txawm yooj yim. Nco ntsoov xaiv cov crucible zoo rau koj daim ntawv thov tshwj xeeb.
2. Npaj tus ntoo plig:
Ua ntej koj pib siv koj cov duab ntoo graphite, nws yog ib qho tseem ceeb kom npaj nws kom siv. Qhov no yog qhov tseem ceeb npaum li nws pab tshem tawm cov impurities thiab ua kom muaj kev xav tau ntawm tus ntoo khaub zig. Pib maj mam tu sab hauv ntawm crucible siv muag muag muag lossis txhuam kom tshem tawm cov xoob xoob. Zam kev siv cov ntaub ntawv muaj abrasive uas yuav kos lossis puas cov graphite sab. Yaug cov crucible nrog dej huv thiab tso cai rau huab cua kom qhuav.
3. Siv txheej Crucible:
Txhawm rau txuas lub neej ntawm koj graphite crucible thiab tiv thaiv nws sab hauv nto, nws raug nquahu kom thov txheej txheem. Refractory txheej los yog sib xyaw ntawm graphite thiab borax tuaj yeem siv. Txhuam ib txheej nyias ntawm cov txheej sib xyaw ua ke rau sab hauv ntawm Crucible, ua kom nws npog tag nrho thaj chaw. Qhov txheej txheem tiv thaiv no txo qhov kev pheej hmoo ntawm cov khoom siv molten reacting nrog cov graphite sab hauv ntawm crucible.
4. Prehua cov crucible:
Preheating koj graphite crucible yog qhov tseem ceeb kom tiv thaiv cov cua sov thiab muaj peev xwm kev puas tsuaj thaum lub sij hawm melting. Tso lub crucible rau hauv ib qho khoob rauv lossis kiln thiab maj mam nce qhov kub kom nws cov haujlwm ua haujlwm. Qhov cua sov me me no tso tseg cov ntoo khaub lig crucible kom nthuav dav heev, txo qhov kev pheej hmoo ntawm kev tawg. Nco ntsoov tias xa mus rau cov chaw tsim khoom cov txheej txheem rau cov lus qhia ntxiv ua ntej.
5. Melting nrog graphite crucible:
Thaum tus crucible yog npaj txhij, koj tuaj yeem pib melting cov khoom siv. Nco ntsoov tias cov crucible yog muab tso ruaj sab hauv lub cub tawg kom ntseeg tau tias muaj kev ruaj khov thiab tiv thaiv ib qho xwm txheej. Ua raws li cov lus qhia tshwj xeeb rau cov khoom siv uas koj siv (txawm tias hlau alloy, iav, lossis lwm yam khoom) kom ua tiav cov txiaj ntsig xav tau.
6. Kev nyab xeeb ntawm kev nyab xeeb thiab kev nyab xeeb:
Kev Tu Kom Zoo ntawm Graphite cruciles yog qhov tseem ceeb rau kev ua tau zoo thiab kev pabcuam lub neej. Ua kom huv si cov khoom seem lossis cov khoom seem tom qab siv. Zam txhob kis tus ntoo khaub lig rau kev hloov pauv kub sai li qhov no yuav ua rau lub zog thermal thiab kev puas tsuaj. Ib qho ntxiv, ib txwm tso kev nyab xeeb ua ntej thiab hnav cov iav tiv thaiv uas tsim nyog, suav nrog cov hnab looj tes kub thiab cov hnab looj tes los tiv thaiv koj tus kheej kom muaj kev phom sij.
Hauv cov ntsiab lus, npaj ib qho graphite Crucible yuav tsum ua tib zoo saib xyuas thiab cov txheej txheem tsim nyog. Los ntawm kev xaiv tus ntoo khaub lig zoo, npaj cov crucible kom raug, thiab ua raws li cov txheej txheem pom zoo yaj, koj tuaj yeem ntseeg tau tias muaj txiaj ntsig zoo thiab txuag tau zoo. Nco ntsoov tias yuav tso kev nyab xeeb ib txwm ua ntej thiab tswj koj lub txaj muag tsis tu ncua kom ntev nws lub neej. Nrog cov kauj ruam no hauv siab, koj yuav npaj tau zoo siv koj graphite crucible tau zoo thiab ua kom nws muaj peev xwm ua ntau yam kev siv.
