Dab tsi ntawm ferrosilicon muaj rau smelting auxiliary cov ntaub ntawv?

Ib txwmferrosiliconhais txog ferrosilicon alloys nrog cov ntsiab lus silicon ntau dua 72% thiab cov ntsiab lus hlau tsawg dua 26%. Nws yog ib qho tseem ceeb pab khoom siv rau smelting hlau thiab yog dav siv nyob rau hauv steel, casting, metallurgy, tshuaj lom neeg kev lag luam thiab lwm yam lag luam. Ordinary ferrosilicon muaj cov khoom zoo txo ​​qis thiab ua kom sov zoo, thiab yog ib qho tseem ceeb ntawm cov khoom siv hauv steelmaking thiab ironmaking.

Tsawg aluminium ferrosiliconhais txog ferrosilicon alloys nrog cov ntsiab lus silicon ntau dua 72%, cov ntsiab lus hlau tsawg dua 26%, thiab cov ntsiab lus txhuas ntawm tsawg dua 1.5%. Tsawg aluminium ferrosilicon muaj cov ntawv thov tseem ceeb hauv steel, casting thiab lwm yam lag luam. Nws muaj cov khoom txo qis thiab ua kom sov zoo, thiab tuaj yeem txo cov pa taws thiab cov pa tawm hauv cov hlau molten.

High silicon ferrosilicon yog ferrosilicon alloy nrog cov ntsiab lus silicon ntau dua 96%. High silicon ferrosilicon muaj cov ntsiab lus silicon siab heev thiab feem ntau yog siv los ua tus neeg sawv cev txo qis thiab deoxidizer hauv casting thiab steelmaking. Nws muaj cov yam ntxwv ntawm kev hnav zoo, corrosion kuj thiab siab zog.

Tsawg-carbon ferrosiliconyog ferrosilicon alloy nrog cov ntsiab lus silicon ntau dua 70% thiab cov ntsiab lus carbon tsawg dua 0.1%. Raws li ib qho tseem ceeb raw khoom ntawm manganese silicon thiab silicon manganese, tsawg-carbon ferrosilicon muaj zoo deoxidation, txo thiab carburizing muaj peev xwm, thiab yog dav siv nyob rau hauv steel, casting thiab lwm yam lag luam.

Micro-carbon ferrosilicon yog ferrosilicon alloy nrog cov ntsiab lus silicon ntau dua 60% thiab cov ntsiab lus carbon ntawm 0.1% thiab 0.3%. Lub luag haujlwm tseem ceeb ntawm micro-carbon ferrosilicon yog los ua tus deoxidizer thiab txo tus neeg sawv cev hauv cov hlau, thiab ua lub luag haujlwm tseem ceeb hauv cov txheej txheem steelmaking. Nyob rau tib lub sijhawm, micro-carbon ferrosilicon tuaj yeem txo qhov viscosity thiab qhov nro ntawm cov hlau molten, yog li txhim kho cov dej ntws thiab plasticity ntawm cov hlau.

Nyob rau hauv cov ntsiab lus, muaj tsib hom ferrosilicon li smelting auxiliary cov ntaub ntawv: zoo tib yam ferrosilicon, low-aluminium ferrosilicon, high-silicon ferrosilicon, tsawg-carbon ferrosilicon thiab micro-carbon ferrosilicon. Txhua hom ferrosilicon alloy muaj nws tus yam ntxwv thiab daim ntawv thov ntau yam, thiab ua lub luag haujlwm tseem ceeb hauv kev tsim khoom.
