Txoj kev txhim kho keeb kwm ntawm Silicon Carbide Crucible

Hauv thaj chaw ntawm Metallurgy, Keeb kwm ntau lawm keeb kwm ntawm silicon carbide crucible siv rau smelting tsis-ferrous hlau tuaj yeem raug rov qab mus rau xyoo 1930. Nws cov txheej txheem nyuaj heev xws li cov khoom siv raw, batching, tes spinning lossis yob txoj kev sib tw, tua hluav taws, roj av thiab noo noo-pov thawj. Cov khoom xyaw uas siv xws li graphite, av nplaum, pyrophyltite clinker lossis high-alumina bauxite clinker, monosilica hmoov los yog ferrosilicon hmoov thiab dej, sib xyaw ua feem. Sij hawm dhau mus, silicon carbide tau sib xyaw los txhim kho thermal conductivity thiab txhim kho kom zoo. Txawm li cas los xij, cov qauv no muaj zog siv hluav taws xob, Ntau Lawm Ntau Lawm, thiab kev poob siab thiab deformation nyob rau hauv ib nrab txheej theem.

Nyob rau hauv kev sib piv, niaj hnub no kev ua tiav qib siab tshaj plaws crucible uas tsim txheej txheem yog isostatic nias. Qhov kev thev naus laus zis no suav cov carbide carbide crucible, nrog phenum resin, tar lossis graphing tus neeg sawv cev, thiab silicon carbide li cov khoom siv raw loj. Lub rescuted crucible muaj tsawg porosity, siab ntom, niaj hnub kev ntxhib los mos thiab muaj zog corrosion tsis kam. Dua li ntawm cov kev ua kom zoo, cov txheej txheem kev sib txuas ua haujlwm tso cov pa luam yeeb thiab hmoov av, ua rau ib puag ncig muaj kuab paug.

Qhov kev hloov pauv ntawm silicon carbide crucible ntau lawm muaj kev cuam tshuam cov kev lag luam kev ua haujlwm, zoo thiab ib puag ncig lub luag haujlwm. Raws li thev naus laus zis, kev tsom xam yog ntawm kev txhim kho cov hau kev los txo cov kev siv hluav taws xob tsawg, luv luv sib tsoo thiab sib xyaw ua ke ib puag ncig. Cov khoom cog ntoo uas tau tshawb txog cov ntaub ntawv kab ke tshiab thiab cov txheej txheem ua kom tiav cov hom phiaj no, ua rau kev sib npaug ntawm kev sib tw thiab tiam no. Raws li xav tau rau cov hlau tsis-ferrous hlau smelting tseem loj hlob ntxiv, kev tsim kho hauv lub luag haujlwm uas tsis txaus siab yuav ua rau lub luag haujlwm tseem ceeb hauv kev luam tawm ntawm nws yog metallurgy.
