Ferrosilicon 72Feem ntau yog muaj li ntawm ob lub ntsiab, silicon thiab hlau, ntawm cov ntsiab lus dab neeg uas nyob hauv qab no 0.02%, thiab cov ntsiab lus ntawm cov kab mob uas tsis sib xws yog hauv qab 0.04%. Fesi 72 cov khoom lag luam nrog qhov loj ntawm 1-3mm nyob hauvpoblossisntoDaim ntawv, nyiaj - grey hauv xim, nrog nws yog xim hlau luster.

Silicon hauvFERRO SiliconMuaj lub zog muaj kuab lom nrog oxygen. Thaum lub sij hawm cov txheej txheem statmaking, ferro silicon 72% tuaj yeem hnov mob nrog oxygen hauv Molten hlau ua si deoxidation lub luag haujlwm, yog li txhim kho qhov zoo ntawm cov hlau. Nyob rau tib lub sijhawm, FESI alloy kuj tseem tuaj yeem cuam tshuam nrog lwm cov khoom siv ntawm cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv hlau.

Cov khoom siv siv

Kev lag luam steelmaking:

Raws li adeoxidizer, 72 # ferrosilicon tuaj yeem tshem tawm oxygen los ntawm Molten Hlau, txhim kho cov hlau, thiab txhim kho cov khoom lag luam zoo thiab ua tau zoo ntawm cov hlau. Nyob rau tib lub sijhawm, nws kuj tseem siv tau ua ib qhoAlloying Tus Neeg Sawv CevTxhawm rau kho cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau, txhim kho lub zog, hardness, nruj thiab yog siv tsis kam ntawm cov hlau loj.

Cam khwb cia hlau kev lag luam:

Hauv cov hlau cam ntau lawm, 72% ferrosilicon yog qhov tseem ceeb inoculant thiab spheroidizer. Thaum siv los ua cov inoculant, nws tuaj yeem txhawb nqa cov dej nag, thiab txhim kho cov khoom siv me me thiab ua cov khoom ntawm cov hlau cam; when used as a spheroidizing agent, it can spheroidize graphite in cast iron, significantly improve the strength, toughness and corrosion resistance of cast iron, and is widely used in the production of cast iron products such as ductile iron and gray cast iron.

Ferrinoalloy ntau lawm:

FESI 72% kuj tseem siv tau los ua tus neeg sawv cev txo qis hauv Ferrroalloy ntau lawm. Piv txwv li, thaum tsim khoomTsawg - rerroalloys, ferrosilicon reacts nrog oxides hauv ore kom txo cov hlau oxides rau cov hlau oxides rau cov hlau ua hlau, yog li tau cov ferroalloys nrog cov ntsiab lus muaj roj carbon tsawg.

Cov khoom lag luam zoo

Uniform loj:

Qhov loj ntawm 1-3mm yog uniform zoo, thiab nws tuaj yeem ua tau zoo dua nrog lwm cov ntaub ntawv raw thaum siv, ua kom muaj kev phom sij thiab muaj kev txhim kho cov khoom lag luam zoo.

Zoo inoculation nyhuv:

Thaum siv raws li inoculant, nws loj yog qhov nruab nrab, txhim kho cov khoom siv neeg siv cov khoom siv tsis xws luag, thiab txhim kho qhov zoo thiab ua kom muaj zog thiab tawm los ntawm cov chaw castings.

Siab tus nqi - ua tau zoo:

Ferrosilicon 72 Cov ntsiab lus silicon yog qhov tsawg dua, tab sis nws tus nqi kuj tseem tsawg. Nyob rau hauv lub neej ntawm kev sib ntsib cov kev sib tham uas cov khoom tsim ua ntawm cov kav hlau thiab cov hlau tsim khoom lag luam thiab txhim kho cov nyiaj txiag ntawm kev lag luam ntawm cov lag luam.
