Ferrosilicon 75 (FeSi75) yog binary alloy tsim los ntawm silicon thiab hlau, nrog cov ntsiab lus silicon ntawm kwv yees li 75%. Nws yog ib qho ntawm feem ntau siv alloying additives hauv steel thiab foundry industries. Nws yog feem ntau tsim los ntawm siab -kub smelting ntawm silica thiab hlau ore nyob rau hauv ib tug hluav taws xob arc rauv. Vim nws muaj peev xwm deoxidation tau zoo thiab muaj txiaj ntsig zoo alloying, nws tau dhau los ua cov khoom tseem ceeb rau kev txhim kho cov khoom hlau thiab txhim kho cov khoom zoo.

Peb cov khoom ferrosilicon 75% muaj cov tshuaj ruaj khov, cov ntsiab lus tsis zoo, thiab qhov loj me, ua tau raws li qhov xav tau nruj ntawm steel mills, foundries, thiab tshwj xeeb alloy manufacturers rau siab - zoo raw khoom.

Ferrosilicon 75

Cov yam ntxwv tseem ceeb thiab qhov zoo

Superior Deoxidation Peev Xwm

Silicon yog lub zog deoxidizing. Cov ntsiab lus ntawm silicon siab (txog 75%) hauv ferrosilicon75 tso cai rau nws sai sai nrog cov pa oxygen hauv cov hlau molten, tsim cov tebchaw ruaj khov (SiO₂) uas yooj yim ntab thiab tshem tawm. Cov txheej txheem no ua tau zoo txo cov pa oxygen hauv cov hlau molten, txo cov porosity thiab kev suav nrog, thiab txhim kho cov purity thiab ntom ntawm cov billet. Piv rau ferrosilicon nrog cov ntsiab lus tsis tshua muaj silicon, nws muaj ntau dua deoxidation efficiency thiab yuav tsum tau tsawg dua silicon ntxiv.

Qhov tseem ceeb Alloying nyhuv

Thaum lub sij hawm deoxidation, qee qhov silicon yaj hauv cov hlau matrix, ua si lub luag haujlwm alloying. Nws zoo txhim kho lub zog, hardness, thiab elastic txwv ntawm steel. Fesi 75 yog ib qho tseem ceeb ntawm cov hlau alloying, tshwj xeeb tshaj yog rau kev tsim cov siab -lub zog qis- hlau alloy, caij nplooj ntoos hlav steel, hnav- cov hlau tsis muaj zog, thiab silicon steel. Tsis tas li ntawd, nws txhim kho qhov sib nqus permeability thiab corrosion kuj ntawm steel.

Lub cev ruaj khov thiab cov txheej txheem sib raug zoo

High Melting Point thiab Zoo Flowability:

Nws cov ntsiab lus melting ntau (kwv yees li 1300-1400 degree) yog ze rau ntawm cov hlau molten, cia nws yaj sai sai thiab sib npaug hauv cov hlau molten. Cov tshuaj tiv thaiv yog ruaj khov thiab tswj tau, tsis txhob muaj teeb meem kev nyab xeeb xws li steel splashing los ntawm kev kub ntxhov.

Ntau hom kev xaiv:

Peb muab ntau yam kev qhia tshwj xeeb los ntawm cov hmoov zoo rau qhov sib txawv ntawm qhov ntau thiab tsawg, ua kom haum rau cov kev sib ntxiv thiab kev sib cais tus nqi ntawm cov txheej txheem sib txawv xws li converters, hluav taws xob furnaces, ladle refining furnaces, thiab casting inoculation kev kho mob. Tsis tas yuav crushing ntxiv los ntawm cov neeg siv khoom, txo qhov kev poob thiab cov nqi ua haujlwm.

Tus nqi zoo heev -Kev ua tau zoo

Piv rauferrosiliconnrog cov ntsiab lus silicon siab dua (xws li ferrosilicon 90), fesi 75% muaj tib yam zoo heev deoxidation thiab alloying zog thaum khav theeb tus nqi lag luam sib tw. Nws yog qhov kev xaiv zoo tshaj plaws los pab cov neeg siv khoom tswj hwm cov nqi tsim khoom thiab ua kom muaj txiaj ntsig zoo tshaj plaws thaum ua kom ntseeg tau qhov zoo ntawm -kawg steel.
