Kev siv Ferrosilicon

(1) Nws yog siv los ua Oxygen scavenger thiab alloying tus neeg sawv cev hauv kev lag luam steelmaking. Txhawm rau kom tau txais cov hlau uas tsim nyog cov tshuaj muaj pes tsawg leeg thiab ua kom cov hlau zoo, deoxidation yuav tsum tau ua nyob rau theem kawg ntawm steelmaking. Cov tshuaj affinity ntawm silicon thiab oxygen yog qhov zoo, yog li ferrosilicon yog lub zog Oxygen scavenger rau steelmaking, siv rau nag lossis daus thiab diffusion deoxidation. Ntxiv qee qhov nyiaj ntawm silicon hauv cov hlau tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm hlau. Yog li ntawd, ferrosilicon kuj tseem siv los ua tus neeg sawv cev alloying thaum smelting structural steel (muaj silicon 0.40-1.75 feem pua), Cov cuab yeej steel (muaj SiO.30-1.8 feem pua), caij nplooj ntoos hlav steel (muaj SiO40-2.8%) thiab silicon steel rau transformers (muaj silicon 2.81-4.8 feem pua ​​). Ib txhij txhim kho cov morphology ntawm inclusions thiab txo cov ntsiab lus ntawm cov roj cov ntsiab lus nyob rau hauv molten steel yog ib tug zoo tshiab technology los txhim kho steel zoo, txo nqi, thiab txuag hlau. Tshwj xeeb tshaj yog tsim nyog rau deoxygenation yuav tsum tau nruam casting molten steel, kev xyaum tau ua pov thawj tias ferrosilicon tsis tsuas yog ua tau raws li qhov yuav tsum tau deoxygenation ntawm steelmaking, tab sis kuj muaj desulfurization kev ua tau zoo thiab qhov zoo xws li lub ntiajteb txawj nqus tshwj xeeb thiab muaj zog nkag.
Nyob rau hauv tas li ntawd, nyob rau hauv lub steelmaking kev lag luam, siv cov yam ntxwv ntawm silicon hlau hmoov muaj peev xwm tso tawm ib tug loj npaum li cas ntawm tshav kub thaum lub sij hawm kub-kub olefin firing, nws yog feem ntau siv los ua ib tug cua sov neeg sawv cev rau steel ingot kaus mom los txhim kho qhov zoo thiab rov qab tus nqi. ntawm steel ingots.
