Kev sib raug zoo ntawm Cov Khoom Loj Loj ntawm Graphite Cov Khoom Thiab Lawv Cov Khoom

Ib qho tseem ceeb ntawm kev siv graphite yog kev tsim cov khoom siv refractory, suav nrog refractory cib, crucibles, nruam casting hmoov, pwm cores, pwm, ntxuav cov neeg ua haujlwm thiab cov ntaub ntawv kub resistant. Vim tias cov khoom siv graphite muaj ntau yam zoo heev, lawv tau siv dav hauv metallurgy, tshuab, hluav taws xob, tshuaj, textile thiab lwm yam kev lag luam. Thaum cov khoom siv graphite yog siv los ua cov khoom siv thiab cov khoom siv tsis zoo, cov khoom yuav tsum muaj qhov ntom ntom ntom ntom. Qhov ntom ntom ntawm cov khoom graphite muaj qhov cuam tshuam ncaj qha rau nws cov hluav taws xob conductivity, thermal conductivity, txhua yam muaj zog, thiab oxidation kuj. Tsis tas li ntawd, qhov ntau ntom kuj hloov permeability, smoothness thiab hnav tsis kam ntawm cov khoom. Kev nce ntau qhov ntom ntom tsis yog qhov zoo rau kev txhim kho cov thermal contraction coefficient thiab txo cov pwm. Yog li ntawd, graphite cov khoom siv nyob rau hauv thermal poob siab tej yam kev mob yuav tsis tau ib-sidedly caum siab bulk ntom.

Cia peb nkag siab txog kev sib raug zoo ntawm cov khoom ntom ntom ntawm cov khoom graphite thiab lawv cov khoom? Saib cov ntsiab lus hauv qab no rau cov ntsiab lus: Kev sib raug zoo ntawm kev siv hluav taws xob vim muaj cov khoom lag luam graphite, yog li cov tsis kam ntawm graphite cov khoom yog cuam tshuam rau nws cov tuab . Cov kev sib raug zoo ntawm kev ceev ntom ntom thiab cov tshuab ua muaj zog {2}}}} qhov kev cia siab ntawm cov tshuab khoom siv zog ntawm cov khoom lag luam graphite. Lub zog ntawm cov khoom graphite nyob ntawm qhov ntom ntom ntawm cov khoom. Cov kev sib raug zoo ntawm kev ceev ntom, thermal conductivity thiab thermal poob siab kuj zoo ntawm graphite yog nruab nrab ntawm cov txhuas thiab cov hlau me me. Feem ntau, qhov qis dua qhov tshwj xeeb tsis kam, qhov siab dua thermal conductivity ntawm cov khoom, thiab cov khoom siv nrog kev kho cua sov siab tshaj 2600 degrees. Cov kev sib raug zoo ntawm kev ceev ntom ntom thiab tshwj xeeb tiv thaiv cov nyhuv ntawm kev ceev ceev ntawm thermal conductivity.

Graphite electrodes thiab graphite cov khoom raws li cov khoom siv, qhov cuam tshuam ntawm lawv cov thermal shock tsis kam ntawm kev siv tau raug lees paub los ntawm tib neeg, thiab cov thermal conductivity, tensile zog, Young's modulus, thermal contraction coefficient thiab lwm yam ntsuas uas txiav txim siab thermal shock resistance factor. Ob qho tib si muaj feem xyuam nrog ntau qhov ntom ntawm cov khoom. thiab nce nrog nce bulk ntom. Yog li ntawd, qhov teeb meem ntawm "kev tsim lub cev ntom ntom" tau tsa. Kev xaiv ntawm "kev tsim lub cev ntom ntom" yuav tsum ua raws li cov khoom siv khoom siv. Rau cov khoom tsim los ntawm cov khoom siv raw thiab cov txheej txheem sib txawv, lawv "qhov tsim nyog qhov ntom ntom" yuav txawv.
