Kev Txij Nkawm Ntawm Graphite Silicon Carbide Crucible

Nyob rau hauv teb ntawm cov txheej txheem kev lag luam,npaimGraphite Silicon Carbide Crucible Ua si lub luag haujlwm tseem ceeb hauv ntau yam kev siv xws li metallurgy, foundry thiab tshuaj siv tshuaj txiag. Txhawm rau kom ntseeg tau tias kev ua tau zoo thiab muaj peev xwm ntawm cov cuab yeej tseem ceeb no, muaj kev tu cov kev tu kom zoo.

Thawj thiab foremost, cia ntawm graphiteGraphite Silicon Carbide Crucible yuav tsum ua tib zoo mloog. Tej noGraphite Silicon Carbide Crucible Yuav tsum tau khaws cia rau hauv ib puag ncig qhuav thiab tiv thaiv los ntawm noo noo txhua lub sijhawm. Nws raug nquahu kom muab lawv tso rau hauv ib daim ntawv ntoo qhuav lossis ntoo kom muab ib txheej ntxiv ntawm kev tiv thaiv. Fragility yog ib qho kev txhais ntawm cov xeeb ntxwv ntawm graphiteGraphite Silicon Carbide Crucible thiab yuav tsum yog li ntawd ua tib zoo saib xyuas thaum kev thauj mus los. Txhua hom kev cuam tshuam lossis kev co yuav tsum raug nruj me ntsis kom tiv thaiv kev puas tsuaj.

Crucible yuav tsum yog maj preheated rau 500°C ua ntej siv. Thaum ntxiv cov tshuaj cua kub ntxiv, nws yog ib qho tseem ceeb kom xav txog lub peev xwm ntawm Crucible thiab ua kom paub tseeb tias tus nqi ntxiv yog nruab nrab ntawm ib feem peb thiab ob feem peb ntawm nws cov ntim. Tsis tas li ntawd, cov cuab yeej thiab cov clamps siv rau kev tsis tuaj yeem tsim kho raws li cov duab ntawm tus ntoo khaub zig thiab muaj lub zog clamping muaj zog los tiv thaiv kev puas tsuaj.

Thaum lub sij hawm cov txheej txheem ntawm kev ntxiv cov ntaub ntawv, nws yog ib qho tseem ceeb kom tswj hwm cov nyiaj ntawm crucolved nyob rau hauv Crucible thiab zam kev ua kom nruj los tiv thaiv kev nthuav dav. Thaum tshem tawm cov swb thiab Coke los ntawm sab hauv thiab sab nraud phab ntsa ntawm crucible ntawm Crucible, nws pom zoo kom coj mus rhaub maj mam los tiv thaiv kev puas tsuaj. Qhov chaw ua kom zoo nyob rau hauv qhov cub ua kuj tseem ceeb, nrog cov crucible cia ntawm qhov kev ncua deb ntawm cov phab ntsa thiab muab tso rau hauv qhov chaw rau kev ua tau zoo tshaj plaws.

Kev siv kev siv tas mus li pab cov ntoo plig tau ua kom pom nws cov kev ua tau zoo. Txawm li cas los xij, ntau dhau ntawm cov kev sib txuas ua ke ntawm primators thiab cov ntxiv yuav tsum raug zam vim tias lawv tuaj yeem txo lub neej pabcuam ntawm tus ntoo khaub lig. Txhawm rau txuas ntxiv cov kev pabcuam lub neej ntawm Crucible, nws pom zoo kom tig nws ib hlis ib zaug thaum siv.

Ib qho ntxiv, nws yog ib qho tseem ceeb kom tsis txhob muaj kev txhaj tshuaj ncaj qha ntawm cov nplaim hluav taws xob oxidizing nplaim taws mus rau sab ntoo thiab hauv qab crucible raws li qhov no yuav ua rau kev puas tsuaj. Los ntawm kev ua raws li cov lus qhia txij nkawm no, cov chaw muaj peev xwm ua kom paub meej txog kev ncua ntev thiab ua haujlwm ntawm lawv graphiteGraphite Silicon Carbide Crucible, thaum kawg pab txhawb rau kev ua haujlwm du ntawm ntau yam ntawm cov txheej txheem thiab cov ntawv thov.
