Tungsten pas nrig yog ib qho tseem ceeb ntawm cov khoom siv hlau uas paub txog nws qhov siab melting point, thermal conductivity, siab kub, thiab siab zog. Tungsten rods feem ntau yog ua los ntawm tungsten alloy, uas yog tsim los ntawm kev siv tshwj xeeb high-temperature hmoov metallurgy technology muab tungsten alloy rods uas tsis muaj thermal expansion coefficient, zoo thermal conductivity, thiab cov khoom zoo heev. Qhov sib ntxiv ntawm tungsten alloy cov ntsiab lus txhim kho lub machinability, toughness, thiab weldability ntawm cov khoom, daws teeb meem ntsig txog kev kho cua sov ntawm lwm yam khoom siv.
Cov ntawv thov kev lag luam: Tungsten rods ua lub luag haujlwm tseem ceeb hauv kev lag luam, nrog rau lawv cov ntsiab lus siab melting thiab qis thermal expansion coefficient ua rau lawv yog cov khoom siv zoo tshaj plaws rau qhov chaw kub kub. Piv txwv li, tungsten hlab yog cov khoom tseem ceeb ntawm quartz nruam melting rauv, nrog rau cov crucibles thiab accessories siv rau ruby thiab sapphire siv lead ua kev loj hlob thiab tsis tshua muaj ntiaj teb melting nyob rau hauv LED kev lag luam.
Lub cev muaj zog ntawm tungsten rods muaj xws li siab purity (feem ntau tshaj 99.95% purity), siab ceev (feem ntau siab tshaj 18.2g / cm³), pom zoo ua hauj lwm kub hauv qab 2500 ℃, thiab tshwj xeeb thermal expansion coefficient thiab tshwj xeeb kub muaj peev xwm. Cov yam ntxwv no ua rau tungsten rods ua tau zoo nyob rau hauv daim ntawv thov uas yuav tsum tau kub thiab siab loads.
Tsis tas li ntawd, cov txheej txheem tsim khoom ntawm tungsten rods suav nrog kev rho tawm tungsten los ntawm tungsten ore thiab tom qab ntawd ua cov pas nrig hlau los ntawm cov hmoov hlau metallurgy. Ntshiab tungsten rods muaj lub melting point ntau dua (3422 ° C) thiab ib tug series ntawm zoo heev lub cev lub cev, xws li tsawg coefficient ntawm thermal expansion thiab zoo thermal conductivity, uas pab kom lawv tswj tau zoo nyob rau hauv ntau yam huab cua.
