Dab tsi yog cov ntawv thov ntawm ferrosilicon?

Ua ntej, nws yog siv los ua deoxidizer thiab alloying tus neeg sawv cev hauv kev lag luam steelmaking. Txhawm rau kom tau txais cov hlau nrog cov tshuaj muaj txiaj ntsig zoo thiab ua kom cov hlau zoo, deoxidation yuav tsum tau ua thaum kawg ntawm steelmaking. Cov tshuaj affinity ntawm silicon thiab oxygen yog loj heev. Yog li ntawd, ferrosilicon yog ib qho muaj zog deoxidizer rau steelmaking, uas yog siv rau nag lossis daus thiab diffusion deoxidation. Ntxiv qee qhov nyiaj ntawm silicon rau cov hlau tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm cov hlau.

Yog li, ferrosilicon kuj tseem siv los ua tus neeg sawv cev alloying thaum smelting steel qauv (muaj silicon 0.40-1.75%), cov cuab yeej hlau (muaj silicon 0.30-1.8%), caij nplooj ntoos hlav steel (muaj silicon 0.40-2.8%) thiab silicon steel rau transformer ( muaj silicon 2.81-4.8%).

Tsis tas li ntawd, nyob rau hauv kev lag luam steel ua, ferrosilicon hmoov tuaj yeem tso tawm ntau cov cua sov hauv qhov kub thiab txias. Nws feem ntau yog siv los ua tus neeg sawv cev cua sov ntawm ingot cap los txhim kho qhov zoo thiab rov qab los ntawm ingot.
