Ferrosilicon pab txhawb rau Alloying thiab Silicon Control li cas?
Ferrosilicon ua haujlwm raws li kev tswj hwm silicon hauv cov hlau.
Nws tso cai rau steelmakers:
Kho cov ntsiab lus silicon precisely
Txhim kho hardness thiab elasticity
Txhim kho cov khoom sib nqus hauv hluav taws xob hlau
Stabilize microstructure thaum solidification
Qhov no ua rau FeSi tseem ceeb rauRaws li FeSi alloy muaj pes tsawg leeg tswj.
Dab tsi yog qhov cuam tshuam rau Mechanical Properties of Steel?
Ferrosilicon txhim kho:
Lub zog tensile
Hardness
Elasticity
Thaum tshav kub kub kuj
Hnav tsis kam
Cov kev txhim kho no nyob ntawm qhov ntau npaum li cas thiab qib steel.
Vim li cas Ferrosilicon nyiam nyob rau hauv qee qib Steel?
Ferrosilicon yog nyiam vim nws:
