Metallurgical ferrosilicon rau steel mills thiab foundries

Ferrosilicon yog ib qho tseem ceeb tshaj plaws ferroalloys hauv metallurgy. Nws lub luag haujlwm tseem ceeb yog kom ua tau zoo deoxidize kua hlau, tswj cov ntsiab lus silicon thiab txhim kho cov qauv ntawm cov hlau. Ua tsaug rau cov khoom no, FeSi pab tsim cov hlau huv nrog lub zog ntau dua, zoo dua ductility thiab nce load kuj.

Vim li cas ferrosilicon suav tias yog cov khoom tseem ceeb rau kev tsim cov hlau zoo?

Ferrosilicon ib txhij ua haujlwm ntawm tus neeg sawv cev deoxidizing thiab cov khoom siv ntxiv.

Thaum melting, yaj oxygen muaj nyob rau hauv cov kua hlau. Yog hais tias nws tsis raug tshem tawm, oxide inclusions, pores thiab internal defects tsim. Silicon muaj cov tshuaj lom neeg ua haujlwm siab rau cov pa oxygen thiab zoo khi nws, tsim slag.

Raws li qhov tshwm sim:

tus naj npawb ntawm non-metallic inclusions txo;

steel purity nce;

nto zoo txhim kho;

qhov kev pheej hmoo ntawm kev tawg yog txo.

Dab tsi cov yam ntxwv ntawm ferrosilicon siv hauv metallurgy?

Yuav ua li cas ferrosilicon tshem tawm oxygen los ntawm cov kua hlau?

Silicon reacts nquag nrog yaj oxygen hauv yaj.

Cov tshuaj tiv thaiv yooj yim zoo li no:

Si + O → SiO₂

Lub resulting silicon dioxide dhau mus rau hauv slag thiab raug tshem tawm ntawm cov hlau.

Qhov tsawg dua cov pa oxygen nyob hauv cov hlau, qhov siab dua nws qhov ceev thiab kev ntseeg tau ntawm txhua yam.

Yog vim li cas ferrosilicon yog dav siv nyob rau hauv:

hluav taws xob arc rauv (EAF);

oxygen- hloov ntau lawm (BOF);

ladle metallurgy (LF);

kev tsim khoom tshwj xeeb thiab cov qauv hlau.

ferrosilicon cuam tshuam li cas lub zog ntawm cov hlau?

Tom qab deoxidation, silicon tseem nyob hauv cov hlau raws li cov khoom siv alloying.

Nws txhawb:

nce lub zog tawm los;

nce tensile zog;

txhim kho hardness;

nce hnav tsis kam;

txhim kho elastic zog.

Yog li ntawd, silicon yog ib qho tseem ceeb ntawm ntau yam qauv thiab caij nplooj ntoos hlav steels.

Yuav ua li cas ferrosilicon txhim kho kev huv ntawm cov hlau?

Lub purity ntawm steel ncaj qha nyob ntawm tus naj npawb ntawm non-metallic inclusions.

Thaum siv cov khoom zoo ferrosilicon:

cov ntsiab lus ntawm oxides txo qis;

txhim kho slag tshem tawm;

qhov yuav ua rau muaj kev puas tsuaj sab hauv raug txo;

homogeneity ntawm cov qauv nce.

Qhov no yog qhov tseem ceeb tshwj xeeb rau:

automotive hlau;

cov yeeb nkab steel;

bearing steel;

high-strength tsim steel.

ferrosilicon cuam tshuam li cas rau microstructure ntawm cov hlau?

Kev tswj cov ntsiab lus ntawm silicon pab txhawb kev tsim cov qauv zoo sib xws.

Qhov no ua rau:

nplej zom;

nce viscosity;

txhim kho kev cuam tshuam lub zog;

txo qhov kev pheej hmoo ntawm intercrystalline tsis xws luag.

Yog li ntawd, cov hlau tuaj yeem tiv taus cov khoom hnyav thiab ua haujlwm ntev.

Vim li cas ferrosilicon pab txo cov nqi tsim khoom?

Siv FeSi tso cai rau koj mus:

nce cov qoob loo ntawm usable hlau;

txo tus naj npawb ntawm qhov tsis xws luag;

txo qhov noj ntawm cov khoom kim heev alloying;

nce tus nqi nqus ntawm alloys.

Rau cov tuam txhab metallurgical niaj hnub no txhais tau tias kev lag luam ruaj khov ntau dua.

FeSi75 vs FeSi72

FeSi75 vs Tsawg Aluminium FeSi

FeSi72 vs Tsawg Carbon FeSi

Yuav ua li cas xaiv cov qib zoo ntawm ferrosilicon?

Qhov kev xaiv nyob ntawm qhov yuav tsum tau ua rau cov hlau kawg.

Rau cov qauv siv hlau, FeSi72 feem ntau yog siv.

Rau lub zog siab thiab cov qauv tseem ceeb, FeSi75 feem ntau yog siv.

Rau cov kabmob, cov cuab yeej thiab qib tshwj xeeb, cov pa roj carbon tsawg lossis qis-aluminium ferrosilicon yog nyiam.

Xaus

Ferrosilicon yog ib qho ntawm cov khoom tseem ceeb tshaj plaws nyob rau hauv niaj hnub metallurgy. Nws zoo tshem tawm cov pa oxygen los ntawm cov kua hlau, txo cov naj npawb ntawm kev suav, txhim kho microstructure thiab nce cov khoom siv ntawm cov hlau. Los ntawm kev sib txuas cov haujlwm ntawm tus neeg saib xyuas deoxidizing thiab cov khoom siv alloying, FeSi tso cai rau kev tsim cov hlau uas muaj zog dua, huv dua thiab txhim khu kev qha ntawm cov nqi tsim khoom.
