Dab tsi yog qhov txawv ntawm qis-aluminium ferrosilicon thiab zoo tib yam ferrosilicon siv?

Tsawg-aluminium ferrosiliconthiabzoo tib yam ferrosiliconmuaj qee qhov sib txawv hauv kev siv, uas yog vim lawv cov tshuaj sib txawv thiab cov yam ntxwv ua haujlwm.

Ordinary ferrosilicon yog ib qho hlau uas muaj silicon thiab hlau, uas feem ntau yog siv rau hauv cov hlau smelting ua deoxidizer thiab alloying caij. Nws lub luag haujlwm tseem ceeb suav nrog:

1. Deoxidizer:Hauv kev tsim cov hlau, cov ferrosilicon zoo tib yam yog siv los tshem tawm cov pa oxygen los ntawm cov hlau molten, uas pab txhim kho cov hlau zoo thiab tiv thaiv qhov pores thiab lwm yam tsis xws luag hauv cov hlau.

2. Alloying element:Nws tuaj yeem ua kom cov ntsiab lus silicon hauv steel thiab txhim kho lub zog thiab hardness ntawm hlau.

3. Kho qhov muaj pes tsawg leeg ntawm molten steel:Ordinary ferrosilicon yog siv los kho qhov muaj pes tsawg leeg ntawm cov hlau molten kom ua tau raws li cov qauv zoo.

Tsawg-aluminium ferrosilicon yog ib qho ferrosilicon alloy nrog cov ntsiab lus aluminium qis, thiab nws lub ntsiab feature yog tias nws muaj tsawg dua txhuas. Nws cov kev siv tseem ceeb suav nrog:

1. Steel deoxidizer:Tsawg-aluminium ferrosilicon muab cov txhuas tsawg dua thaum lub sij hawm deoxidation txheej txheem thiab tsim nyog rau cov qib steel nrog kev tswj nruj ntawm cov ntsiab lus txhuas.

2. Tshwj xeeb steel ntau lawm:Thaum tsim cov hlau tshwj xeeb nrog cov ntsiab lus tsis tshua muaj txhuas (xws li qee cov hlau tsis muaj steel thiab cov hlau ceev ceev), cov txhuas ferrosilicon tsawg tuaj yeem siv los tswj cov muaj pes tsawg leeg.

3. Txo qhov cuam tshuam ntawm txhuas:Qee qhov xwm txheej, aluminium ntau dhau tuaj yeem ua rau muaj kev cuam tshuam tsis zoo rau kev ua haujlwm ntawm cov hlau, xws li ua rau brittleness lossis lwm yam tsis xws luag hauv cov hlau, yog li cov aluminium ferrosilicon tsawg pab kom tsis txhob muaj cov teeb meem no.

Ordinary ferrosilicon yog tsim rau cov txheej txheem steel ntau lawm, thaum tsis tshua muaj txhuas ferrosilicon yog tsim nyog rau cov sij hawm uas yuav tsum tau nruj tswj ntawm txhuas cov ntsiab lus. Kev xaiv ntawm cov ferrosilicon alloy yog nyob ntawm qhov yuav tsum tau ua ntawm cov khoom kawg thiab cov kev cai tshwj xeeb rau cov alloy muaj pes tsawg leeg thaum lub sijhawm tsim khoom.
