Nyob rau hauv niaj hnub steel ntau lawm, ferrosilicon alloy ua hauj lwm raws li ib tug indispensable tseem ceeb additive. Nws cov khoom siv tshuaj tshwj xeeb daws ntau yam teeb meem hauv kev smelting, kev ua tau zoo, kev tsim steel tshwj xeeb, thiab casting, ncaj qha txiav txim siab qhov zoo thiab siv tau ntawm cov khoom steel.
Ferrosilicon lub luag haujlwm tseem ceeb yog deoxidizing molten steel:
Oxygen nyob rau hauv molten hlau ua rau brittleness thiab porosity defects. Silicon nthuav tawm muaj zog affinity rau oxygen, ceev ceev khi nrog nws ntawm qhov kub thiab txias los tsim slag uas raug tshem tawm. Cov txheej txheem no tso tawm cov cua sov, tswj cov molten steel kub thiab txo lub zog noj. Tsuas yog 1-3 kilograms ntawm ferrosilicon ib tuj ntawm cov pa roj carbon zoo tib yam kom paub meej qhov zoo.
Raws li "regulator" ntawm cov khoom steel, ferrosilicon enables lub hom phiaj optimization:
Ntxiv rau cov qauv hlau txhim kho lub zog thiab tawv, ua rau nws tsim nyog rau kev tsim kho; incorporating nws mus rau hauv cov cuab yeej steel boosts hardness thiab hnav tsis kam, ncua lub cuab tam lub neej; siv nws nyob rau hauv hluav taws xob hlau txhim kho magnetic permeability thiab txo lub zog noj, ua rau nws yog ib tug tseem ceeb additive rau hauv tsev thiab motors.
Nyob rau hauv smelting ntawm tshwj xeeb hlau xws li stainless hlau, ferrosilicon qhia muaj zog txo cov khoom:
Nws tuaj yeem txo cov ntsiab lus tseem ceeb uas ua rau oxidation thiab poob, xws li chromium, rov qab mus rau hauv cov hlau, ua kom muaj kev tiv thaiv corrosion thiab kev ua haujlwm tseem ceeb ntawm cov hlau tshwj xeeb. Tib lub sijhawm, siab -silicon ferrosilicon nrog cov ntsiab lus qis carbon tiv thaiv kev taw qhia ntawm impurities, pab tsim cov qib siab -purity alloy steels.
Nyob rau hauv cov txheej txheem casting, ferrosilicon ua raws li ib tug inoculant rau refine castings ' grain qauv thiab txhawb graphite spheroidization. Qhov no txo qhov tsis xws luag xws li shrinkage kab noj hniav thiab kab nrib pleb, boosting toughness ntawm castings xws li automotive crankshafts thiab mechanical Cheebtsam los ntawm ntau tshaj 30%. Qhov no ua kom muaj kev ntseeg siab thiab txuas ntxiv lub neej kev pab cuam tom qab tsim.
