Hav nyob ntawd! Raws li ib tug neeg muab khoom ntawm graphite crucibles, kuv yog super stoked coj koj mus rau ib qho kev taug kev los ntawm cov txheej txheem txaus nyiam ntawm yuav ua li cas cov tub phem no tau ua. Graphite crucibles yog qhov tseem ceeb hauv ntau qhov kev lag luam, tshwj xeeb tshaj yog hauv cov hlau smelting. Lawv tuaj yeem tiv taus qhov kub thiab txias heev, ua rau lawv mus - xaiv rau ntau qhov chaw tsim khoom.
Cov khoom siv pib
Thawj yam ua ntej, cia peb tham txog cov khoom siv raw. Graphite yog lub hnub qub ntawm kev ua yeeb yam ntawm no. Peb qhov chaw siab - zoo graphite, uas yog ib daim ntawv ntawm carbon nrog ib co zoo nkauj tshwj xeeb zog. Nws muaj lub siab melting point thiab yog ib tug zoo conductor ntawm tshav kub, uas yog ib qho tseem ceeb rau lub crucible.
Tab sis graphite ib leeg tsis txaus. Peb kuj sib tov rau hauv ib co lwm yam ntaub ntawv xws li av nplaum thiab lwm yam refractory tshuaj. Cov av nplaum ua raws li kev khi, tuav cov graphite hais ua ke. Cov ntaub ntawv refractory pab txhim kho lub crucible lub peev xwm los tiv thaiv tshav kub thiab tshuaj tiv thaiv. Peb ua tib zoo xaiv cov ntaub ntawv no raws li lawv qhov zoo thiab lawv yuav ua haujlwm zoo li cas.
Kev npaj cov hmoov sib tov
Thaum peb tau txais tag nrho peb cov ntaub ntawv, nws yog lub sij hawm mus sib tov. Peb pib los ntawm crushing cov graphite rau hauv cov hmoov zoo. Qhov no yog qhov tseem ceeb vim tias nws tso cai rau kev sib xyaw ua ke zoo dua nrog lwm cov khoom. Cov av nplaum thiab cov khoom siv refractory kuj tau ua tiav rau qhov zoo sib xws.
Tom qab ntawd, peb muab tag nrho cov khoom xyaw no tso rau hauv ib lub khob loj. Xav txog nws zoo li lub chav ua noj loj loj, tab sis tsis yog ua ncuav mog qab zib, peb tab tom tsim lub hauv paus rau peb cov crucibles. Peb tsuas yog ntxiv cov dej kom raug rau qhov sib tov kom nws tuaj yeem yooj yim. Nws yog me ntsis zoo li kneading mov paj. Peb yuav tsum tau txais qhov sib xws yog li ntawd nws yooj yim rau cov duab tab sis tsis ntub los yog qhuav.
Shaping lub Crucible
Tam sim no los txog qhov kev lom zem - shaping lub crucible. Muaj ob peb txoj kev sib txawv peb tuaj yeem siv tau, tab sis ib qho ntawm feem ntau yog txoj kev compression molding. Peb muab cov khoom sib xyaw thiab muab tso rau hauv pwm uas muaj cov duab ntawm lub crucible peb xav tau.
Cov pwm yog muab tso rau hauv hydraulic xovxwm. Cov xovxwm siv ntau lub siab rau cov khoom siv, nyem nws rau hauv cov duab ntawm cov pwm. Lub siab no yuav pab kom compact cov khoom, ua rau lub crucible muaj zog thiab ntom.
Lwm txoj kev yog isostatic nias txoj kev. Nyob rau hauv cov txheej txheem no, cov khoom yog muab tso rau hauv ib tug saj zawg zog pwm thiab ces submerged nyob rau hauv ib tug kua. Lub siab yog siv sib npaug ntawm txhua qhov kev qhia, uas ua rau muaj kev sib txuam ntau dua thiab muaj zog crucible.
Qhuav thiab tua hluav taws
Tom qab lub crucible yog zoo li tus, nws yuav tsum tau qhuav. Peb muab cov crucibles tsim tshiab rau hauv qhov cub kom qhuav. Cov txheej txheem ziab yog qhov tseem ceeb heev vim nws tshem tawm cov dej ntau dhau los ntawm qhov sib tov. Yog tias muaj dej ntau dhau hauv lub crucible thaum nws raug rho tawm haujlwm, nws tuaj yeem ua rau tawg.
Thaum cov crucibles qhuav, nws yog lub sij hawm rau tua. Kev tua hluav taws zoo li qhov kev xeem zaum kawg rau peb cov crucibles. Peb muab lawv tso rau hauv qhov kub siab - qhov cub. Qhov kub hauv qhov cub tuaj yeem ncav cuag 1000 degrees Celsius lossis siab dua, nyob ntawm seb hom graphite thiab lwm yam khoom siv.
Thaum lub sij hawm tua, cov av nplaum thiab lwm yam binders nyob rau hauv qhov sib tov harden, thiab cov graphite hais sib txuas ua ke. Qhov no muab lub crucible nws lub zog thiab tshav kub - resistant zog. Cov txheej txheem tua hluav taws tuaj yeem siv sijhawm ob peb teev lossis ib hnub, nyob ntawm qhov loj thiab qhov nyuaj ntawm lub crucible.
Tiav kov
Tom qab tua hluav taws, cov crucibles yuav luag npaj txhij, tab sis lawv tseem xav tau qee qhov ua tiav. Peb pib los ntawm kev tshuaj xyuas txhua lub crucible kom zoo zoo. Peb tab tom nrhiav rau txhua qhov tawg, chips, lossis lwm yam tsis xws luag. Yog tias peb pom ib qho, lub crucible yog kho lossis muab pov tseg.
Tom qab ntawd, peb ua qee qhov machining kom tau lub crucible mus rau qhov ntev npaum li cas. Qhov no yuav suav nrog kev sib tsoo cov npoo kom lawv du lossis drilling qhov yog xav tau.
Thaum kawg, peb siv txheej tshwj xeeb rau lub crucible. Cov txheej no pab tiv thaiv lub crucible los ntawm cov tshuaj tiv thaiv thiab kuj ua rau nws yooj yim dua los ntxuav.
Daim ntawv thov thiab cov khoom lag luam
Graphite crucibles yog siv nyob rau hauv ntau yam kev lag luam. Hauv cov hlau smelting, lawv tau siv los yaj cov hlau xws li kub, nyiaj, tooj liab, thiab txhuas. Lawv kuj tau siv hauv chav kuaj rau ntau yam kev sim tshuaj.
Yog tias koj nyob hauv cov hlau - smelting kev lag luam, koj kuj yuav txaus siab rau qee yam ntawm peb cov khoom. Mus saib peb Foundry Graphite Crucible, uas yog tsim tshwj xeeb rau cov ntawv thov kev tsim. Peb kuj muaj Graphite Stoppers thiab Graphite Crystallizers, uas yog qhov tseem ceeb rau kev tswj cov dej ntws ntawm cov hlau molten thiab rau cov txheej txheem kev loj hlob siv lead ua raws li.
