Yuav Ua Li Cas Tau Txais Cov Khoom Siv Silicon Manganese Alloy? Tshawb xyuas Cov Kev Ntsuam Xyuas hauv Kab Lus no!

Silicon manganese alloy yog ib hom hlau alloy nrog dav daim ntawv thov thiab siab yield. Ferroalloy tsim los ntawm silicon, manganese, hlau, carbon thiab lwm yam me me yog tsuas yog siv los ua deoxidizer thiab alloy additive hauv steelmaking. Nws cov ntsiab lus tseem ceeb silicon thiab manganese muaj kev sib raug zoo nrog oxygen. Thaum cov kua hlau ntxiv rau cov pa oxygen, nws tuaj yeem hloov mus rau hauv slag deoxidize nrog cov khoom loj, cov ntsiab lus melting tsawg thiab yooj yim rau ntab. Yog tias siv silicon thiab manganese deoxidation ib leeg nyob rau hauv tib lub sijhawm, qhov kub hnyiab yuav ntau dua li nws.

Nws qhov ntsuas tau muab faib ua 6517 thiab 6014, tab sis ntau tus neeg siv khoom xav tau 6818 silicomanganese, uas yog hais txog 6517. Cov ntsiab lus carbon ntawm ob qhov ntsuas no yuav tsum tsis siab tshaj 2.5, phosphorus tsis siab tshaj {{8} }.3 thiab sulfur tsis siab tshaj 0.05

Nyob rau hauv nws cov ntau lawm, kev xaiv ntawm tsim nyog slag hom yog qhov txuas tseem ceeb ntawm nws cov txheej txheem kev ua haujlwm, tab sis kuj yog ib qho kev ntsuas tseem ceeb los txhim kho cov kev ntsuas kev tsim khoom. Nyob rau hauv cov txheej txheem ntau lawm, tsim nyog collocation ntawm manganese ore thiab xaiv ntawm tsim nyog slag hom yuav tsis tau tsuas yog tau txais cov khoom zoo, tab sis kuj stabilize lub qub zus tau tej cov furnace ore. Nyob rau tib lub sijhawm, txhim kho cov kev ntsuas kev tsim khoom, txo cov nqi tsim khoom, ua kom tag nrho lub tuam txhab cov txiaj ntsig kev lag luam.

Ib qho manganese ore lossis ntau hom manganese ore (xws li manganese nplua nuj slag) tuaj yeem siv rau hauv nws cov khoom. Txhawm rau kom ntseeg tau tias cov khoom tsim nyog, qhov piv ntawm manganese rau hlau thiab manganese rau phosphorus hauv ore yuav tsum ua tau raws li qee yam kev cai:

Collocation ntawm raw khoom:

Txhawm rau kom tau txais cov khoom lag luam zoo, tsuas yog cov khoom ntawm manganese ore yog siv hauv manganese ore. Nws tsis tsim nyog coj cov ntsiab lus raws li qhov ntsuas. Nws cov khoom siv tsis yog tsuas yog manganese ore, tab sis kuj muaj lwm yam khoom siv. Txiav txim siab txoj kev npaj tsim khoom.

Nws cov ntaub ntawv raw yog: manganese ore, manganese nplua nuj slag, silica, coke.

Kev suav cov mis ntawm cov khoom xyaw dav dav rau cov ntsiab lus manganese:

Manganese cov ntsiab lus=rauv manganese ÷ (manganese ore ntxiv rau txo tus neeg sawv cev ntxiv rau silica ntxiv hnyav ntxiv rau lwm yam ntxiv))

Los ntawm cov txheej txheem kev suav saum toj no, nws tuaj yeem pom tias txawm tias lub cub tawg manganese cov ntsiab lus siab, yog tias muaj cov khoom siv ntxiv ntxiv, cov ntsiab lus ntawm lub cub tawg manganese yuav txo qis, uas yuav cuam tshuam rau kev tsim khoom zoo ntawm silicon manganese alloy nqi.

Kev xav tau rau txhua yam khoom siv raw:

1. Lub impurity P2O5 nyob rau hauv manganese ore yog qis dua, thiab P2O5 tsub kom cov phosphorus ntsiab lus nyob rau hauv lub alloy. Qhov loj me me ntawm manganese ore feem ntau yog 10-80mm, tsawg dua 10mm tsis tshaj 10 feem pua ​​​​ntawm tag nrho;

2. SiO2 Ntau dua lossis sib npaug li 97 feem pua ​​​​hauv silica, P2O5 < 0.02, particle loj 10-40mm, tsis muaj av thiab khib nyiab;

3. Cov pa roj carbon ntau hauv coke Ntau dua lossis sib npaug li 84 feem pua, cov hmoov tshauv Tsawg dua lossis sib npaug li 14 feem pua, coke particle loj, feem ntau me me thiab nruab nrab hluav taws xob rauv siv 3-13mm, qhov cub loj siv {{5} }mm;

Nws cov txheej txheem ntau lawm yog qhov tseem ceeb tib yam li cov pa roj carbon ferromanganese, tab sis nws yog qhov nyuaj rau tus tswv ntawm lub tshuab cua sov dua li cov pa roj carbon ferromanganese. Yog li ntawd, kev ua haujlwm yuav tsum tau ua tib zoo saib xyuas, kev txiav txim siab qhov cub kom raug, kho raws sijhawm.

Lub cim ntawm lub cub hluav taws xob ib txwm yog tias qhov ntsuas qhov tob ntawm electrode yog qhov tsim nyog, tus nqi sinking tusyees, lub qhov ncauj hluav taws kub sib npaug, qhov muaj pes tsawg leeg yog qhov ruaj khov, thiab cov kev ntsuas kev lag luam zoo. Qhov tseeb piv ntawm cov khoom xyaw yog tus yuam sij kom ntseeg tau tias lub cub tawg zoo li qub.

Qhov teeb meem tseem ceeb ntawm qhov piv ntawm cov khoom xyaw yog qhov teeb meem ntawm kev faib cov pa roj carbon. Thaum tus neeg saib xyuas kev txo qis hauv tus nqi ntau dhau, qhov kev coj ua ntawm tus nqi yog kho kom zoo, qhov tam sim no nce, cov electrode nce, lub crucible shrinks, qhov tshwm sim ntawm lub cev qhuav dej nce, qhov tshwm sim ntawm lub qhov cub lub qhov ncauj yog tib yam li ntawm txo tus neeg sawv cev ntawm ferrosilicon ntau dhau, vim tias qhov txo tus neeg sawv cev ntawm tus nqi ntau dhau, qhov txo ntawm silica ntau dua, thiab cov ntsiab lus ntawm silicon ntawm cov hlau yog siab dua. Yog tias tus neeg sawv cev txo qis ntau dhau, cov electrode nce siab heev, lub qhov cub hauv qab kub qis, thiab cov ntsiab lus ntawm silicon hauv cov hlau yuav txo qis.

Lub hauv paus ntawm slag kuj muaj kev cuam tshuam zoo rau kev smelting ntawm silicon manganese alloy.

Cov alkalinity siab dhau lawm, lub slag kub yog heev txo, qhov kub thiab txias nyob rau hauv lub cub tawg tsis siab, ntxiv rau, CaO thiab SiO2 ua ke rau hauv silicate, cov no ua rau cov ua ke rau hauv silicate, SiO2 rov qab yog nyuaj, alloy silicon ntsiab lus tsis tuaj yeem sawv. . Tsis tas li ntawd, cov alkalinity siab dhau heev lawm, cov slag yog nyias heev, cov hlau yuav siv sij hawm ntau raw cov ntaub ntawv, cov hlau qhov hluav taws xob yog ib qho yooj yim mus hlawv, lub cub tawg qhov muag tsis yooj yim rau ntsaws, alkalinity siab dhau yog tsis zoo.
