Kev ceev faj rau kev siv high-purity graphite crucible
Dec 04, 2022
Hauv kev lag luam metallurgical, high-purity graphite crucible muaj ntau yam kev siv. Nws lub luag haujlwm tseem ceeb yog khaws ntau yam kua hlau. Raws li cov chaw tsim khoom metallurgical, graphite crucibles yuav raug siv. Txwv tsis pub, yuav muaj qee qhov teeb meem tom qab siv thiab ntau lawm. Tom ntej no Cia peb qhia txog cov teeb meem dab tsi yuav tsum tau them nyiaj rau thaum siv high-purity graphite crucible.
1. Lub high-purity graphite crucible yog ib qho yooj yim kom ntub, thiab cov khoom yuav ua mos tom qab damp, thiab yuav deformed thaum ntaus los ntawm tej yam khoom, thiab thaum dej nkag mus rau high-purity graphite crucible, nws yuav cuam tshuam. nyob rau hauv Cov ntaub ntawv raw nyob rau hauv tag nrho Bloom yuav ua rau lub dilution ntawm raw cov ntaub ntawv, thiab ib co tshuaj tiv thaiv kuj yuav tshwm sim rau ntxiv cuam tshuam rau nws zoo teeb meem, yog li kev ntsuas dej yuav tsum tau ua kom zoo.
2. Txawm hais tias qhov zoo ntawm high-purity graphite crucible yog qhov zoo heev thiab nws tsis yooj yim rau kev puas tsuaj, nws yuav tsum tau ua tib zoo saib xyuas. Kev poob qis los ntawm qhov siab lossis kev sib tsoo thiab kev sib tsoo muaj qhov cuam tshuam me ntsis ntawm qhov zoo ntawm cov graphite crucible, tab sis yog tias nws txuas ntxiv mus ntev, nws yuav muaj qhov tshwm sim ntawm qhov tawg. Tom qab qhov xwm txheej no tshwm sim, tsis muaj txoj hauv kev los kho nws. Nws tsuas tuaj yeem hloov tau dua.
3. Tsis txhob ua kom sov lub siab-purity graphite crucible rau ntawm qhov qhib nplaim taws. Vim tias nws cov thermal conductivity tsis yog qhov tshwj xeeb txaus, nws tsis muaj qab hau rau cua sov rau saum, thiab nws tsis pom zoo siv cov pa taws thiab hluav taws kub hnyiab lossis cia nws tshwm dub rau hauv qab. Vim hais tias cov high-purity graphite crucible muaj zoo thermal conductivity thiab kub tsis kam, nyob rau hauv high kub siv, thermal expansion coefficient yog me me, nws muaj ib tug tej yam strain tiv thaiv kom kub ceev thiab ceev txias, thiab nws muaj zog corrosion kuj rau acid thiab alkali kuab tshuaj. Zoo tshuaj stability. High-purity graphite crucible muaj ntau yam kev siv, feem ntau yog siv rau smelting ntau yam non-ferrous hlau xws li nyiaj, txhuas, txhuas, tooj liab, zinc, nruab nrab carbon steel thiab tsawg hlau. Lub high-purity graphite crucible muaj qhov ruaj khov zoo, kev ua haujlwm ntev, txo cov roj noj, txo kev siv zog, txhim kho kev siv zog, thiab tsim kom muaj txiaj ntsig zoo ntawm kev lag luam.
