Tsawg aluminium ferrosilicon 75yog aferrosilicon alloynrog cov ntsiab lus aluminium tsawg, feem ntau qis dua 0.5%. Cov hauv qab no yog cov lus qhia ntxaws ntxaws rau Low aluminium ferrosilicon 75, suav nrog nws cov tshuaj muaj pes tsawg leeg thiab kev siv tseem ceeb:
Tshuaj muaj pes tsawg leeg
Cov tshuaj tseem ceeb ntawm Low aluminium ferrosilicon 75 suav nrog:
Silicon (Si):lub ntsiab tivthaiv, feem ntau nyob ib ncig ntawm 75%.
Hlau (Fe):qhov seem, accounting rau feem ntau ntawm cov alloy.
Aluminium (Al):cov ntsiab lus qis, feem ntau tswj tau qis dua 0.5%.
Kev siv tseem ceeb
Kev siv lub ntsiab ntawm Low aluminium ferrosilicon 75 yog raws li cov khoom siv ntxiv hauv cov hlau smelting. Nws tshwj xeeb daim ntawv thov scenarios thiab zoo muaj xws li:
1, Alloying steel:
Tsawg aluminium ferrosilicon 75 feem ntau yog ntxiv rau cov hlau kom nce cov ntsiab lus silicon. Silicon muaj qhov tseem ceeb cuam tshuam rau hardness, lub zog thiab corrosion kuj ntawm steel, thiab tuaj yeem txhim kho lub zog tensile thiab hnav tsis kam ntawm steel.
2, Refining nyhuv:
Cov silicon hauv ferrosilicon tuaj yeem ua ke nrog oxides, yog li tshem tawm cov oxides thiab lwm yam impurities hauv cov hlau, txhim kho cov purity thiab kev ua haujlwm ntawm cov hlau.
3, Tswj cov ntsiab lus txhuas hauv cov hlau:
Vim nws cov ntsiab lus tsis tshua muaj aluminium, qis-aluminium ferrosilicon yog tsim rau steel smelting txheej txheem uas muaj kev txwv rau cov ntsiab lus txhuas. Lub xub ntiag ntawm txhuas tuaj yeem muaj kev cuam tshuam tsis zoo rau cov khoom tshwj xeeb ntawm cov hlau, xws li kev ua haujlwm thiab kev ua haujlwm vuam, yog li cov ntsiab lus txhuas yuav tsum tau tswj hwm hauv qee cov hlau ntau lawm.
4, Kev tsim cov qib tshwj xeeb steel:
Raws li qee cov qib steel tshwj xeeb thiab cov txheej txheem tshwj xeeb, qis-aluminium ferrosilicon yog xav tau rau kev hloov kho cov alloy kom paub meej tias cov khoom kawg tuaj yeem ua tau raws li qhov tshwj xeeb thiab cov kev xav tau zoo.
Feem ntau, qis-aluminium ferrosilicon plays ib qho tseem ceeb alloying thiab refining lub luag hauj lwm nyob rau hauv steel smelting. Los ntawm kev tswj cov ntsiab lus ntawm aluminium, nws tuaj yeem ua tau raws li qhov yuav tsum tau ua rau cov khoom tshwj xeeb ntawm cov khoom steel. Xaiv cov qauv tsim nyog ferrosilicon thiab cov lus qhia tshwj xeeb yog qhov tseem ceeb hauv kev ua kom zoo dua qub thiab xaiv raws li cov txheej txheem steel smelting tshwj xeeb thiab cov khoom siv kawg.
