Kev siv tshuab khoom
Cov txheej txheem yaj ntawm lub tshuab nqus tsev electron beam tsim cov phaj niobium. Cov niobium bar uas tsis tau forged ua ntej raug smelted rau hauv ib lub niobium ingot los ntawm lub tshuab nqus tsev electron beam melting furnace. Nws feem ntau muab faib ua ib qho smelting thiab ntau qhov smelting. Peb feem ntau siv ob zaug smelted niobium ingots. Nyob ntawm cov khoom xav tau, peb tuaj yeem ua ntau dua ob qho smelting.
Daim Ntawv Thov
Kev lag luam superconducting
Siv los tsim cov ntawv ci niobium
Lub tshuab cua sov hauv lub cub tawg kub heev
Siv los tsim cov yeeb nkab niobium welded
Siv rau hauv kev tsim cov khoom cog rau tib neeg.
