Ferrosilicon, feem ntau sau ua FeSi los yog "ferro silicon," yog ib qho ntawm cov ferroalloys siv dav hauv steelmaking thiab foundry. Cov neeg yuav khoom feem ntau nug seb nws yog "ua los ntawm" rau ob qho laj thawj. Ua ntej, lawv xav tau cov lus teb meej meej: cov ntsiab lus twg hauv nws. Qhov thib ob, lawv xav tau cov lus teb rau kev yuav khoom: dab tsi raw cov ntaub ntawv thiab cov txheej txheem txheej txheem txiav txim seb cov khoom xa tuaj zoo ib yam, huv, thiab ntseeg tau hauv kev tsim khoom. Ob qhov teeb meem, thiab lawv txuas nrog.
Dab tsi yog ferrosilicon ua los ntawm chemistry?
Ntawm nws lub hauv paus, ferrosilicon yog ua los ntawmsilicon thiab hlau. Cov ntsiab lus ntawm silicon sib txawv raws qib. Qib siab dua (xws li FeSi75) muaj ntau silicon ib tuj dua li qib qis (xws li FeSi45 lossis FeSi65). Qhov sib npaug feem ntau yog hlau, ntxiv rau me me ntawm lwm cov ntsiab lus uas tshwm sim raws li impurities lossis cov khoom me me. Cov ntsiab lus me no tsis yog "random." Lawv raug cuam tshuam los ntawm cov khoom siv raw, kev xyaum ua kom sov, thiab kev tswj kom zoo.
Hauv kev yuav khoom, tus neeg yuav khoom yuav tsum kho ferrosilicon li "Si + Fe + tswj impurity qauv." Cov qauv impurity yog qhov sib txawv ntawm cov neeg xa khoom thiab feem ntau cuam tshuam rau yaj stability thiab rov ua dua. Txawm hais tias ob yam khoom raug muag raws li qib tib, lawv yuav coj txawv txawv yog tias cov impurities drift los yog ntau ntau sib xyaw.
Dab tsi raw khoom siv los ua ferrosilicon?
Ferrosilicon feem ntau yog tsim los ntawm peb pawg tswv yim tseem ceeb:
- Silica qhov chaw
Cov silicon yog los ntawm silica -cov khoom siv raw, feem ntau quartz lossis quartzite. Qhov zoo ntawm cov khoom siv silica cuam tshuam rau ob qho tib si cov tshuaj tiv thaiv kev ua haujlwm thiab kev pheej hmoo ntawm cov khoom tsis zoo. Ruaj khov, huv si silica inputs txhawb nqa tus cwj pwm smelting zoo ib yam.
- Hlau qhov chaw
Cov khoom siv hlau tuaj yeem los ntawm cov hlau- cov khoom siv coj los siv rau hauv qhov cub. Kev xaiv thiab kev huv ntawm cov hlau tuaj yeem cuam tshuam cov theem impurity thiab tag nrho cov khoom sib xws.
- Cov pa roj carbon reductant
Cov pa roj carbon reductants yog siv los txo cov silica rau silicon hauv qhov cub. Cov no tuaj yeem suav nrog cov khoom siv carbon xaiv rau kev ua haujlwm, kev huv, thiab nqi. Reductant xaiv tseem ceeb vim tias nws tuaj yeem cuam tshuam cov pa roj carbon-txoj kev coj cwj pwm thiab kev qhia txog impurity.
Tsis tas li ntawd, cov neeg tsim khoom tuaj yeem siv cov ntaub ntawv txhawb nqa thiab kev tswj xyuas cov txheej txheem uas pab ua kom lub qhov cub ua haujlwm ruaj khov. Los ntawm tus neeg yuav khoom qhov kev xav, daim ntawv qhia tseeb yog qhov tseem ceeb tsawg dua qhov tshwm sim: qib chemistry zoo ib yam, tswj cov impurities, thiab lub cev ruaj khov.
ferrosilicon ua li cas?
Feem ntau ferrosilicon yog tsim nyob rau hauv ib qhohluav taws xob submerged arc rauv. Lub tswv yim yooj yim yog ncaj nraim: silica raug txo qis ntawm qhov kub siab thaum muaj cov pa roj carbon thiab hlau -cov khoom siv los tsim cov silicon- hlau alloy. Tab sis "cov ntsiab lus tseem ceeb" tsis zoo ib yam li "cov txiaj ntsig zoo ib yam." Kev ua tau zoo nyob ntawm qhov cub ruaj khov, kev npaj them nqi, thiab tom qab-smelting tuav.
Ib qho yooj yim manufacturing flow zoo li no:
- Kev npaj them nqi
Cov ntaub ntawv raw yog npaj thiab proportioned. Cov neeg tsim khoom zoo tswj cov dej noo thiab qhov loj me ntawm cov khoom siv hluav taws xob kom lub cub tawg ruaj khov.
- Smelting thiab txo
Nyob rau hauv lub cub tawg, silica yog txo thiab silicon dissolves rau hauv hlau los tsim ferrosilicon. Lub tshuab hluav taws xob stability cuam tshuam cov txiaj ntsig thiab kev sib xws.
- Tapping thiab casting
Lub molten alloy yog tapping thiab cam khwb cia. Kev tswj kom txias thiab tuav tau pab txo qis kev tawg thiab kev nplua tom qab.
- Crushing, tshuaj ntsuam, thiab sizing
Tom qab solidification, ferrosilicon yog crushed thiab tshuaj xyuas rau hauv cov pob loj loj uas phim cov neeg siv khoom. Qhov no yog qhov uas muaj ntau qhov kev tsis txaus siab tshwm sim, vim tias qhov loj me thiab cov ntsiab lus raug nplua tuaj yeem hloov pauv thaum ua haujlwm thiab kev thauj mus los.
- Packing thiab labeling
Cov khoom yog ntim thiab sau npe rau traceability. Ntshiab batch marks thiab cov ntaub ntawv zoo ib yam yog qhov tseem ceeb rau kev tiv thaiv kev tsis sib haum xeeb thiab rov ua dua.
Dab tsi ntxiv hauv ferrosilicon ntxiv rau silicon thiab hlau?
Cov neeg yuav khoom feem ntau xav paub "lwm yam khoom" vim tias cov feem pua me me tuaj yeem muaj teeb meem. Cov khoom me me tuaj yeem suav nrog cov ntsiab lus uas tshwm sim ntawm COA nyob ntawm qib thiab kev tswj hwm tus neeg muag khoom. Txoj hauv kev zoo los daws qhov no tsis yog los kwv yees daim ntawv teev npe impurity thoob ntiaj teb, tab sis txhawm rau txheeb xyuas cov ntsiab lus tseem ceeb rau koj daim ntawv thov thiab xav kom lawv ntawm COA rau txhua qhov kev xa khoom.
Yog tias koj yuav ntau zaus, qhov tseem ceeb tshaj plaws tsis yog ib qho COA uas zoo nkaus li zoo, tab sisntau-rau- ntau ruaj khov. Qhov kev ruaj ntseg ntawd yog lub peev xwm muab khoom siv. Ib tus neeg muag khoom uas tuaj yeem muab cov ntaub ntawv sib txuas ua ke thiab qhov sib npaug sib npaug feem ntau yooj yim ua haujlwm nrog lub sijhawm.
Cov neeg yuav khoom yuav tsum kuaj xyuas dab tsi kom paub meej ferrosilicon zoo?
Ib daim tshev yuav khoom ib txwm muaj xws li:
- Batch - txuas COAuas phim cov khoom xa tuaj thiab ntim cov cim
- Qib chemistryua raws li koj daim ntawv thov (silicon ntau thiab txhua qhov kev txwv tseem ceeb)
- Tswj impurityraws li koj txoj kev pheej hmoo, tsis yog cov kev xav dav dav
- Lump size range thiab fines tolerancephim rau koj txoj kev pub mis
- Packing kev ncaj ncees thiab labelinglos tiv thaiv cov khoom thiab khaws cia traceability
Yog tias koj tab tom nrhiav ferrosilicon rau kev xa khoom xa tawm, cov kev tswj hwm no feem ntau tiv thaiv kev tsis sib haum xeeb feem ntau ua ntej lawv tshwm sim.
