70 72 75 Ferrosilicon Deoxidizer

Ferrosiliconyog qhov tseem ceeb tshaj plaws thiab siv dav hauv kev sib xyaw deoxidizer thiab alloying additive hauv kev lag luam steel. AON METALS '70/72/75 series fesi yog tsim los ntawm siab - zoo coke, steel seem, thiab quartz (los yog silica) raws li raw cov ntaub ntawv, smelted ntawm kub kub nyob rau hauv ib tug hluav taws xob arc rauv, nrog rau cov ntsiab lus silicon precisely tswj nyob rau hauv lub 70% -75% ntau yam.

Nws lub luag haujlwm tseem ceeb hauv steelmaking:

Dej nag deoxidation:Siv qhov muaj zog affinity ntawm silicon thiab oxygen, silicon reacts nrog yaj oxygen nyob rau hauv molten hlau los ua SiO₂, tsim tau yooj yim floating silicate khoom, yog li txo cov pa oxygen nyob rau hauv cov hlau thiab txhim kho nws ceev.

Alloying:Silicon yog ib qho tseem ceeb alloying khoom rau feem ntau steel qib, txhim khu lub zog, hardness, elastic txwv, thiab kub tsis kam ntawm hlau. Silicon cov khoom siv ntxiv dag zog rau cov hlau yog qhov thib ob rau phosphorus.

Kev pab cua sov:Cov tshuaj tiv thaiv ferrosilicon deoxidation (2FeO + Si=SiO₂ + 2 Fe) yog cov tshuaj tiv thaiv exothermic, uas yuav pab ua kom qhov kub thiab txias thiab txo lub zog noj.

Customizable Loj:

Blocks:10-50mm, 10-60mm, 10-100mm (Suitable rau hluav taws xob furnaces thiab ladle additives)

Granules:1-3mm, 3-8mm (Suitable for casting inoculation thiab cored hlau)

Hmoov:0-1mm, 40-200 mesh (Suitable rau vuam cov ntaub ntawv thiab exothermic agents)

Kev Tswj Xyuas Zoo:

Kev ntsuas ua ntej- cub tawg:Tiag - lub sij hawm saib xyuas siv ncaj qha - nyeem spectrometer kom paub meej cov khoom raug.

Particle Loj Guarantee:Standardized vibrating sieving system kom ntseeg tau tias qhov loj me me raws li cov neeg siv khoom xav tau.

Kev huv huv:Tom qab sieving, cov khoom siv sib nqus sib cais kom tshem tawm cov impurities, ua kom cov khoom purity.

1. Muaj txiaj ntsig zoo deoxidation, txhim kho hlau purity

Txoj Cai:Silicon muaj ntau dua affinity rau oxygen dua hlau. Thaum ferrosilicon ntxiv rau cov hlau molten, cov tshuaj tiv thaiv hauv qab no tshwm sim: [Si] + 2[O]=SiO₂(s). Lub generated SiO₂ ua ke nrog MnO, FeO, thiab lwm yam, nyob rau hauv cov hlau molten kom tsim tsawg-melting-point silicates (xws li 2MnO·SiO₂, 2FeO·SiO₂). Cov khoom ua kua no yooj yim sib tsoo, sib sau ua ke, thiab ntab rau hauv cov slag, yog li txo cov pa oxygen tag nrho thiab tsis yog{10}}hlau suav nrog hauv cov hlau.

Cov ntaub ntawv:Nyob rau hauv cov pa smelting, siv75% ferrosilicon hmoovrau nag lossis daus deoxidation tuaj yeem txo cov pa oxygen ntawm cov hlau molten los ntawm 40-60% thiab tag nrho cov nyiaj tau los ntawm ntau dua 30%.

2. Tus nqi sib piv, muaj zog txheej txheem tswj

Tsis zoo li oxidation ceev ntawm txhuas, cov tshuaj tiv thaiv deoxidation ntawm ferrosilicon yog me me thiab yooj yim los tswj. Qhov no ua rau nws yog ib qho zoo tshaj plaws deoxidizer hauv cov txheej txheem steelmaking: nws tuaj yeem txo cov pa oxygen sai sai yam tsis muaj cov tshuaj tiv thaiv ntau dhau ua rau kub hnyiab thiab txaws ntawm cov hlau molten los yog tsim kom muaj ntau qhov nyuaj-kom- tshem tawm cov pawg ntawm Al₂O₃ suav nrog.

3. Kev lag luam thiab kev ua haujlwm zoo, nrog tus nqi qis

Tus nqi -effectiveness:Silicon yog ib qho tseem ceeb nyob rau hauv lub ntiaj teb lub crust, thiab cov nqi tsim khoom ntawm ferrosilicon yog deb tshaj li deoxidizers xws li txhuas thiab calcium. Raws li lub hauv paus ntsiab lus ntawm kev ua kom tau raws li qhov yuav tsum tau deoxidation, siv ferrosilicon rau ua ntej -deoxidation los yog qhov kawg deoxidation yog ib qho ntawm cov nqi qis tshaj - cov nqi xaiv ib tuj ntawm cov hlau.

Alloying tus nqi ntxiv:Cov silicon ntxiv tsis tsuas yog deoxidizes tab sis kuj yog absorbed los ntawm molten hlau raws li ib tug alloying caij (feem ntau nrog ib tug rov qab tus nqi ntawm 85% -95%), ncaj qha mus rau lub mechanical zog ntawm cov hlau, ua kom tiav "ib peev, ob rov qab."

4. Txhim kho physicochemical zog ntawm molten steel

Txo cov kua dej kub:Qhov nce hauv silicon cov ntsiab lus hauv cov hlau molten me ntsis txo qis nws cov kua dej kub, uas yog qhov zoo rau cov txheej txheem nruam casting.

Nce resistivity:Silicon tuaj yeem ua kom muaj zog ntawm cov hlau, yog li silicon steel los xij (hluav taws xob hlau) yog cov khoom tseem ceeb rau kev tsim cov transformers thiab lub cev muaj zog cores.

Q: Muaj pes tsawg qhov sib txawv ntawm deoxidation nyhuv ntawm 70 ferrosilicon thiab 75 ferrosilicon?

A: 70 ferrosilicon muaj cov ntsiab lus silicon 5-8 feem pua ​​​​cov ntsiab lus qis dua. Ntxiv tib 2 kg ntawm silicon ua rau 0.1-0.16% tsawg silicon qhia. Rau cov pa roj carbon steel, qhov sib txawv no tau txais; rau hlau alloy, 75 ferrosilicon raug pom zoo.

Q: Ntau npaum li cas kim dua yog qis- txhuas ferrosilicon (Al Tsawg dua lossis sib npaug li 0.5%) dua li cov ferrosilicon zoo tib yam?

A: Feem ntau, nws yog 200-500 yuan / tuj kim dua. Rau cov neeg muas zaub ua automotive steel nplooj ntawv thiab pipeline steel, qhov sib txawv ntawm tus nqi no tau txais; rau qhov zoo tib yam rebar, nws tsis tsim nyog.
