Qhov sib txawv loj tshaj plaws ntawm cov pa roj carbon tsawg ferrosilicon thiab zoo tib yamferrosiliconboils mus rau ib lo lus: carbon. Ordinary ferrosilicon muaj cov ntsiab lus carbon ntawm 0.2% -0.5%, thaum peb lc ferrosilicon tuaj yeem ua tiav hauv qab 0.1%, txawm tias qis dua 0.01%.

Vim li cas thiaj tswj tau cov ntsiab lus carbon tsawg? Vim tias qee cov qib steel tsis tshua muaj siab rau carbon:

Automotive steel (IF steel):Kev xav tau carbon tsawg dua lossis sib npaug li 0.005%. Siv cov ferrosilicon zoo tib yam yuav dhau qhov kev txwv no.

Hluav taws xob steel (silicon steel):Cov pa roj carbon rhuav tshem cov khoom sib nqus, yog li qis heev -carbon ferrosilicon yuav tsum tau siv.

Tsawg- carbon structural steel:Cov ntsiab lus carbon siab cuam tshuam rau weldability thiab toughness.

Yog li ntawd, yog tias koj cov hlau ntau lawm muaj cov pa roj carbon, cov ferrosilicon zoo tib yam siv tsis tau; tsawg carbon fesi yuav tsum tau siv. Peb faib peb cov hlau ua peb qib raws li cov ntsiab lus carbon:

LC1 (carbon Tsawg dua lossis sib npaug rau 0.1%):Rau zoo tib yam qis- carbon structural steel, xws li Q355ND thiab choj hlau. Hom hlau no muaj cov kev xav tau carbon, tab sis lawv tsis nruj li.

ULC1 (carbon Tsawg dua lossis sib npaug rau 0.05%):Siv rau automotive steel ntawv, xws li DP steel thiab TRIP steel. Hom hlau no yuav tsum tau stamping; cov ntsiab lus carbon siab yuav ua rau tawg.

SLC1 (carbon Tsawg dua lossis sib npaug rau 0.01%):Siv rau hluav taws xob hlau (silicon steel). Carbon cuam tshuam cov khoom sib nqus thiab yuav tsum tau tswj kom tsis tshua muaj siab.

Lus Cim: Silicon cov ntsiab lus sib cuam tshuam nrog daim ntawv thov- qib Si siab dua (75% -80%) yog siv rau kev sib tsoo (piv txwv li, hluav taws xob hlau), thaum qis Si qib (65% -70%) tsom rau deoxidation (xws li cov qauv hlau). Cov ntsiab lus carbon ncaj qha txiav txim siab qib steel sib raug: automotive IF steel xav tau SLC1 (C Tsawg dua lossis sib npaug rau 0.01%), thaum qis dav dav - carbon steel txais LC1 (C Tsawg dua lossis sib npaug li 0.1%).

Cov ntsiab lus zoo ntawm LC Ferro Silicon (vs. Regular Ferrosilicon)

1. Tsis muaj cov pa roj carbon ntxiv rau hlau:

Ordinary ferrosilicon muaj 0.3% -0.5% carbon. Ntxiv 1 kg / ton ntawm carbon qhia 0.005% carbon rau hauv cov hlau. Rau cov neeg muas zaub ua automotive IF steel, cov pa roj carbon yuav tsum tsawg dua los yog sib npaug rau 0.005%, uas yuav tshaj qhov txwv nrog ferrosilicon zoo tib yam. Siv peb cov SLC1 (cov pa roj carbon tsawg dua lossis sib npaug li 0.01%), cov pa roj carbon ntxiv yog qhov tsis txaus ntseeg nrog tib tus nqi.

2. Tsis muaj cracking thaum lub sij hawm stamping:

Lub Boon rau Automotive Steel Sheets: Ib lub tuam txhab European tsheb hlau siv cov ferrosilicon zoo tib yam rau DP600 duplex steel, uas tsis tu ncua tawg thaum lub sij hawm stamping. Tom qab peb tau hais kom hloov mus rau ULC1 (cov pa roj carbon tsawg dua lossis sib npaug li 0.05%), qhov elongation tau nce los ntawm 18% mus rau 22%, thiab cov seem seem poob los ntawm 35%. Cov neeg siv khoom tom qab tau xa tag nrho lawv cov qis- carbon steel xaj rau peb.

3. Kev txuag hluav taws xob: qis hlau poob hauv hluav taws xob hlau:

Cov neeg muas zaub ua transformer cores muaj qhov xav tau siab heev rau cov khoom sib nqus ntawm silicon steel. Qhov me me ntawm cov pa roj carbon zoo tib yam ferrosilicon cov ntaub ntawv "pinnings" ntawm cov ciam teb, ua rau cov hlau poob (piv txwv li, nkim hluav taws xob). Hloov mus rau SLC1 (cov pa roj carbon tsawg dua lossis sib npaug li 0.01%) txo cov hlau poob los ntawm 15% -20%, ua kom lub zog hloov pauv tau zoo.

4. Tus Cwj Pwm - Tsawg qhov suav nrog:

Cov txheej txheem tsim cov pa roj carbon tsawg ferrosilicon (xws li refining) nws tus kheej txo cov qib sulfur thiab phosphorus. Yog li ntawd, kev siv peb cov khoom ua rau 20% -25% tsawg kev suav nrog hauv cov hlau piv rau cov ferrosilicon zoo tib yam.

Kev lag luam hlau

Steelmaking txheej txheem:

Thaum lub sij hawm steelmaking txheej txheem, qis -carbon ferrosilicon plays lub luag hauj lwm tseem ceeb ntawm deoxidizer thiab alloying tus neeg sawv cev. Nws yog dav siv nyob rau hauv ntau yam steelmaking txheej txheem, nrog rau converter steelmaking thiab hluav taws xob rauv steelmaking. Thaum ua tau zoo - cov pa roj carbon zoo, qhov sib ntxiv ntawm qhov tsim nyog qis - carbon ferrosilicon rau deoxidation zoo txhim kho cov hlau purity thiab txo nws cov ntsiab lus oxygen, yog li txhim kho nws lub zog, tawv, thiab ua haujlwm tau zoo. Nws tseem tuaj yeem ua tus neeg sawv cev alloying, kho cov ntsiab lus silicon hauv cov hlau kom ua tau raws li qhov xav tau ntawm cov qib steel sib txawv. Piv txwv li, nyob rau hauv zus tau tej cov silicon steel los xij, meej tswj cov ntsiab lus ntawm silicon yog ib qho tseem ceeb rau kev txhim kho cov hlau sib nqus permeability thiab txo hysteresis poob.

Casting:

Tsawg-carbon ferrosilicon kuj tseem yog qhov tseem ceeb hauv kev tsim cov hlau thiab hlau. Hauv kev tsim cov hlau nplaum, nws ua haujlwm tseem ceeb ntawm ob qho tib si nodularizer thiab inoculant, txhawb nqa graphite spheroidization thiab ua tiav qhov zoo tshaj plaws graphite morphology nyob rau hauv cov hlau cam khwb cia, txhim kho cov cam khwb cia hlau cov cuab yeej cuab tam, tshwj xeeb tshaj yog lub zog thiab toughness. Qhov no ua rau cov hlau nplaum siv dav hauv kev tsim khoom ntawm cov khoom tseem ceeb xws li tsheb cav, crankshafts, thiab lub zog, ua tau raws li kev lag luam niaj hnub xav tau rau siab - cov khoom siv casting.

Tsis yog -ferrous hlau smelting:

Tsawg-carbon ferrosilicon kuj tseem siv los ua cov khoom siv ntxiv rau hauv cov smelting ntawm qee yam tsis yog-ferrous hlau, xws li tooj liab thiab txhuas. Ntxiv qhov tsim nyog tus nqi qis - carbon ferrosilicon thaum lub sij hawm smelting txheej txheem ntawm tooj liab alloys yuav txhim kho lawv cov casting thiab txhua yam khoom, xws li nce lawv fluidity thiab txo qhov tsis xws luag casting. Nws kuj tseem txhim kho cov alloy lub zog thiab hardness, nthuav nws daim ntawv thov hauv electronics thiab machinery manufacturing.

Lwm qhov chaw:

Hauv kev lag luam refractory, qis- carbon ferrosilicon tuaj yeem siv los tsim cov khoom tshwj xeeb, txhim kho lawv cov thermal shock resistance, hnav tsis kam, thiab oxidation tsis kam, ua rau lawv ua haujlwm ruaj khov thiab ntev ntev nyob rau hauv siab - qhov kub thiab txias, hnyav rau qhov chaw ua haujlwm. Tsis tas li ntawd, hauv kev tsim khoom ntawm qee cov khoom siv tshuaj, qis -carbon ferrosilicon kuj tuaj yeem ua tus cab cab los yog koom nrog cov tshuaj tiv thaiv tshwj xeeb, ua lub luag haujlwm tshwj xeeb.
