Vim tias qhov sib ntxiv ntawm ferrosilicon hmoov tuaj yeem tso tawm cov cua kub ntau, uas ua rau cov dej seem seem tsawg dua, kev sib txuas yog qhov zoo. Lub zog thiab permeability ntawm hom xuab zeb no yog siab, tsis tshua muaj roj txiav thaum pouring, haum rau pouring loj thiab nruab nrab-qhov loj me carbon steel castings. Tab sis cov txheej txheem hardening rau precipitate hydrogen, feem ntau coj teeb meem tshwm sim.
Ferrosilicon hmoov ntxiv rau cam khwb cia hlau tuaj yeem siv los ua cov hlau tsis huv, thiab tuaj yeem tiv thaiv kev tsim cov carbide, txhawb cov nag lossis daus ntawm graphite thiab spheroidisation, txhim kho kev ua haujlwm ntawm cam khwb cia hlau. Ntxiv ib qho koob tshuaj ntawm silicon hauv cov hlau, tuaj yeem ua lub luag haujlwm hauv kev txhim kho lub zog ntawm cov hlau, steel hardness thiab steel elasticity, yog li feem ntau nyob rau hauv smelting ntawm cov qauv steel, cuab yeej steel, caij nplooj ntoos hlav steel thiab transformer nrog silicon steel, kuj yuav hlau. silica hmoov raws li tus neeg sawv cev alloying yuav tsum tau siv, charcoal tsau cov ntsiab lus yuav tsum siab tshaj 80%, cov khoom degree yuav tsum tau tswj nyob rau hauv lub 8-18 hli, nyob rau hauv lub sieve yuav tsum tsawg tshaj li 5%. Cov dej noo uas muaj nyob rau hauv charcoal yuav tsum tsawg dua 16%, cov ntsiab lus volatile tsawg dua 8%, thiab cov hmoov tshauv tsawg dua 8%.
Yog li, nyob rau hauv zus tau tej cov ductile hlau, ferrosilicon hmoov yog ib qho tseem ceeb inoculant (los pab precipitate graphite) thiab spheroidal tus neeg sawv cev. Siv los ua tus neeg sawv cev txo qis hauv ferroalloy ntau lawm. Tsis tsuas yog cov tshuaj affinity ntawm silicon thiab oxygen yog loj heev, tab sis kuj cov pa roj carbon ntsiab lus ntawm siab silica ferrosilicon hmoov yog tsawg heev. Txij li thaum qhov sib ntxiv ntawm ferrosilicon hmoov tuaj yeem tso tawm ntau cov cua sov, uas ua rau cov seem ntawm cov dej noo tsawg thiab zoo rau kev sib txuas. Lub zog thiab permeability ntawm hom xuab zeb no yog siab, tsis tshua muaj roj txiav thaum pouring, haum rau pouring loj thiab nruab nrab-qhov loj me carbon steel castings.
Tau kawg, nyob rau hauv kev yuav khoom lub sij hawm los xaiv ib tug txhim khu kev qha chaw tsim tshuaj paus, peb Hoobkas zus tau tej cov ferrosilicon hmoov zoo, zoo siab txais tos hu rau cov lus qhia.
