Titanium alloysraug suav hais tias yog cov khoom siv zoo tshaj plaws hauv cov khoom siv hauv kev lag luam xws li chaw, dej hiav txwv, thiab lwm yam, vim lawv lub zog tshwj xeeb, muaj zog corrosion-resistant, thiab cov khoom tsis sib nqus. Txawm li cas los xij, tseem muaj qee qhov teeb meem thoob ntiaj teb xws li kev siv hluav taws xob siab thiab tus nqi siab hauv kev tsim cov titanium alloy thiab nws cov khoom siv los ntawm kev siv ingot metallurgy technology.
Kev tshawb fawb qhia tau hais tias crucible nqus induction melting yog ib txoj hauv kev zoo los daws cov teeb meem saum toj no, tab sis kev ua haujlwm siab ntawm cov tshuaj lom neeg.titaniumua rau nws hnov mob nrog yuav luag tag nrho cov paub refractories. Yog li ntawd, cov khoom siv titanium crucible tshiab thiab nws cov thev naus laus zis npaj yog cov yuam sij kom paub txog tus nqi qis, zoo, thiab kev ua haujlwm siab ntawm titanium alloy.
Hauv qhov no, qee cov ntsiab lus tseem ceeb tau sau tseg rau ntawm qhov kev tshawb fawb ntawm cov ntaub ntawv ceramic crucible (corrosion resistance mechanism, ingredient optimization) thiab crucible durability rau induction smelting.titanium alloyhauv tsev thiab txawv teb chaws. Ua ke nrog kev tshawb fawb tsis ntev los no ntawm Huazhong University of Science thiab Technology, cov kev xav tshiab tau muab tso rau hauv nws txoj kev txhim kho yav tom ntej, koj tuaj yeem tshawb nrhiav lawv.
