Ferrotitanium yog dab tsi?
Ferrotitanium (FeTi) yog tsim los ntawm kev sib txuas cov titanium seem, hlau seem, thiab titanium -cov ntaub ntawv bearing los ntawm siab - kub smelting.
Lub resulting alloy yog siv raws li ib tug additive nyob rau hauv steelmaking kom tshem tawm impurities xws li oxygen, nitrogen, sulfur, thiab carbon compounds.
Nws yog muab rau hauv daim ntawv pob lossis granular nyob ntawm daim ntawv thov.
Ferrotitanium ua li cas?
Cov txheej txheem ntau lawm suav nrog siab -kub alloying hauv hluav taws xob arc rauv lossis induction furnaces:
- Kev xaiv ntawm titanium seem lossis daim txhuam cev titanium
- Ntxiv cov hlau seem lossis npua hlau
- Melting nyob rau hauv cov huab cua tswj
- Alloy tsim thiab muaj pes tsawg leeg kho
- Txias, crushing, thiab sizing
