Khoom Description
Tungsten Crucibleyog ib qho ntawm cov khoom siv hlau tungsten, feem ntau muab faib ua sintering molding (siv rau hmoov metallurgy technology), stamping molding, thiab spinning molding. Siv cov tungsten rods rau txoj siav thiab tsim (feem ntau me me), vuam thiab tsim ntau hom, siv cov tungsten daim hlau ntshiab, cov ntawv tungsten, thiab cov tungsten ntshiab ua tiav los ntawm cov txheej txheem sib thooj. Tungsten crucibles tuaj yeem siv rau hauv lub tshuab nqus tsev inert gases hauv qab 2600 degrees. Tungsten muaj lub siab melting thiab boiling point, zoo high-temperature zog, hnav thiab corrosion kuj, siab thermal conductivity, tsawg coefficient ntawm thermal expansion, thiab zoo hardenability.
Tungsten hmoov - sieving - batching - isostatic nias - ntxhib dawb paug tig - nruab nrab zaus sintering - zoo tig - ntim.

siv cov khoom
Tungsten crucibles yog dav siv nyob rau hauv kev lag luam xws li tsawg lub ntiaj teb smelting, quartz iav, hluav taws xob txau, thiab siv lead ua loj hlob.
Txij li thaum lub melting point ntawm tungsten yog siab li 3410 degree, tungsten crucibles yog dav siv los ua core ntim nyob rau hauv industrial furnaces xws li sapphire ib tug siv lead ua loj hlob furnaces, quartz iav smelting furnaces, thiab tsis tshua muaj lub ntiaj teb smelting furnaces. Qhov chaw ua haujlwm kub uas lawv siv feem ntau yog siab dua 2000 degree.
Tshwj xeeb tshaj yog rau sapphire ib leeg siv lead ua kev loj hlob furnaces, tungsten crucibles nrog cov yam ntxwv xws li siab purity, siab ceev, tsis muaj cov kab nrib pleb, meej qhov ntev, du sab hauv thiab sab nrauv phab ntsa, thiab lwm yam yog ib qho tseem ceeb heev rau txoj kev vam meej ntawm cov noob muaju, kev tswj zoo ntawm cov khoom siv lead ua. rub, thiab lwm yam thaum lub sij hawm txoj kev loj hlob ntawm sapphire muaju. Decrystallization thiab ua raws li lub lauj kaub thiab kev pabcuam lub neej ua lub luag haujlwm tseem ceeb.
