Vim li cas Ferrosilicon tseem ceeb hauv Steelmaking?

Ferrosilicon yog cov hlau alloy uas muaj hlau thiab silicon. Ferrosilicon yog cov hlau-silicon alloy ua los ntawm coke, steel scraps, quartz (los yog silica) ua raw khoom thiab smelted nyob rau hauv lub cub hluav taws xob.
Vim muaj kev sib raug zoo ntawm silicon thiab oxygen, tom qab ferrosilicon ntxiv rau steelmaking, cov tshuaj tiv thaiv deoxidation hauv qab no tshwm sim. Silicon dioxide yog cov khoom ntawm deoxidation. Nws yog sib dua li molten steel thiab ntab rau saum npoo ntawm cov hlau thiab nkag mus rau hauv slag, yog li tshem tawm cov hlau hauv cov hlau. Oxygen tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm cov hlau, ua kom cov hlau nplaum permeability ntawm cov hlau, thiab txo cov hysteresis poob ntawm transformer steel.
Nyob rau tib lub sijhawm, txij li SiO2 tso tawm ntau cov cua sov thaum nws tsim tawm, nws kuj tseem muaj txiaj ntsig los ua kom kub ntawm cov hlau molten thaum deoxidizing. Nyob rau tib lub sijhawm, ferrosilicon kuj tseem siv tau los ua cov khoom siv alloying ntxiv thiab tau dav siv hauv cov hlau tsis tshua muaj hlau, lub caij nplooj ntoos hlav steel, cov kabmob hlau, cov hlau tsis muaj cua sov thiab hluav taws xob silicon steel. Ferrosilicon feem ntau yog siv los ua tus neeg sawv cev txo qis hauv ferroalloy ntau lawm thiab kev lag luam tshuaj.
