Kev siv tungsten crucible
Tungsten crucible yog tsuas yog siv nyob rau hauv metallurgical kev lag luam, mechanical processing, iav thiab ceramic kev lag luam thiab lwm yam teb. Tungsten crucible yog ib qho ntawm cov khoom ntawm tungsten, uas yog muab faib ua sintering, stamping, spinning, tig thiab vuam ntawm molybdenum rods. Nws yog ua los ntawm cov ntawv ntshiab tungsten, cov ntawv tungsten thiab cov tungsten rods ntshiab los ntawm cov txheej txheem sib thooj. Nws tuaj yeem siv rau hauv lub tshuab nqus tsev inert gas hauv qab 2600 degrees.
Tungsten muaj qhov siab melting point thiab boiling point, zoo kub lub zog, hnav tsis kam thiab corrosion kuj, thermal conductivity, me thermal expansion coefficient, zoo hardenability, thiab yog dav siv nyob rau hauv tsawg lub ntiaj teb smelting, quartz iav, hluav taws xob txau, siv lead ua kev loj hlob thiab lwm yam kev lag luam.
